The SIM card is missing. After the SIM has been inserted a warm  boot may be required.
• SIM failure.  The SIM card is permanently disabled (e.g. because the wrong PU K has been entered too many times). A 
new SIM is needed.
• Modem failure.  The modem did not respond to commands as expected. If a warm bo ot does not clear this condition, the 
modem may need to be replaced.
• NDIS error.  An internal software error has occurred. If a warm boot does no t clear this condition, Zebra technical 
support may need to investigate further.
Tools Menu
The Tools menu in the main  Wireless WAN dialog box offers some additional, advanced setup features. 
WWAN Data Configuration
Enable Automatic Connect
If the Enable automatic connect check box is checked  (unchecked by default), the Wireless WAN user inter-
face will attempt to establish a  GPRS connection whenever GPRS  is available (e.g. after resume from suspend 
without further user interaction). 
To activate the automatic connection mode:

• Tap on the OK button.
While automatic connecti on mode is enabled, the Connect Data button in the main  Wireless LAN dialog box 
changes to  Disable Auto . To close the currently active connection (if any) and disable  the automatic connection 
mode:
• Tap on  Disable Auto.
Use Virtual Serial Port
If  Use virtual serial port  is enabled, packet data connections are established through the  virtual serial port of 
the WWAN driver rather  than through the WWAN driver directly. This check box should  only be checked if 
certain third-party VPN (Virtual  Private Network) clients are used that do not work c orrectly otherwise. The 
default setting is  disabled (unchecked). 
Enable Automatic Configuration
In most cases,  the data connection is configured automati cally and no user interaction is required. This is true 
even if multiple SIM cards from different operators are used wi th the same device. The connection parameters 
are adjusted automatically when a new SIM card is detected (thi s may require a warm boot). The connection 
parameters are retrieved from a database. 
Manual configuration sho uld be necessary only if:
• One or more parameters in the database are incorrect or a new  operator is not yet in the database. (The 
database should be corrected for  subsequent software releases.)
• An operator has assigned indivi dual GPRS user names and passwo rds. 
• A very large site has its own  APN. Such connections always have to be configured manually.
• A customer has subscribed for a static IP address. By definiti on this must be configured manually.
• An operator may use a differen t APN for certain groups of customers. Since the automatic configuration 
can configure only one APN per operator such connections have t o be configured manually.
Profiles
In the following section, all the  parameters that need to be configured for a connection (such as APN, user 
name, password, DNS server addresses etc.) are referred to as a  ‘profile’. Every profile is identified by an arbi-
trary, unique name. T he profile named Default is special in that it is always present and can neither be edi ted 
nor deleted. The  Default profile uses parameters from a built-in database. The home net work (the network that 
issued the SIM) is used for the database look-up. While there c an be many configured profiles, only one profile 
can be active at any time.
If connection profiles are configured manually, the  Enable automatic configuration check box should normally 
be unchecked.
In one particular use case, manually configured profiles may be  combined with automatic configuration. If 
multiple SIM cards are  used with the same device, each SIM card being from a different operator and some 
or all of them requiring a manua lly set up profile, automatic co
nfiguration may be used to automatically pick 
IMPORTANT Automatic connection mode should  not be used if applications other than the Wireless 
WAN user interface (e. g. Connection Manager ) are expected to open and close 
connections. 
If the automatic connection mode  is enabled and another application closes the GPRS 
connection, the WWAN user inte rface will immediately try to re-establish the connection.
NOTEThe connection setup takes longer  through the virtual serial port.

the correct manually configured  profile for each SIM card. For this to work, each prof ile must be configured 
while the corresponding SIM card is inserted in the device and  initialized (i.e. the status is at least Searching 
for network ).
The  Select profile:  drop-down list in the data conf iguration profile selects to which profile a subsequent action 
applies. A profile named  Default is always present and contains the current parameters from the  database. The 
following actions are available:
Show
The parameters for the selected  profile are displayed when you tap the stylus on this button. For the  Default 
profile, the publicly known passw ord is shown — otherwise, the password is hidden.
Edit
The parameters of the selected p rofile can be edited when you choose the Edit button. Keep in mind that you 
cannot edit the Default profile.
Delete
The selected profile is del eted. You cannot delete the  Default profile.
Activate
When this button is chosen, the selected profile becomes the ac tive profile. Activation is possible only if the 
Enable automatic configuration:  check box is unchecked.
New
Tapping on the  New button allows you to create a new  profile. 
Figure F-4Creating a New Profile
The name of the newly c reated profile must be different from al l existing profiles. Also, the name cannot be 
Default . When the  New Data Profile dialog box is opened,  a proposal for a unique name is filled i n the corre-
sponding entry field. If a manua lly configured profile has a secret password and unaut horized access to the 
device is a concern even after the SIM PIN has been entered, th e password should not be entered in the New 
Data Profile dialog box and the  Prompt user for password check box should be check ed instead. In this case, 
you will be prompted for the passw ord each time a connection is initiated (the  Connect Data  button in the main 
Wireless WAN  dialog box is selected). 
By default the connection uses PAP (Password Authentication Pro tocol), a simple authentication protocol used 
to authenticate a user to a remot e access server or Internet Service Provider. However, if your ISP does not 
support PAP, tapping in the box to the left of  Force PAP authentication disables PAP and directs the connection 
to use CHAP (Challenge Handshake Authentication Protocol) inste ad.

Reset
The Reset  button in the  New Profile and Edit Profile dialog boxes resets all entry fi elds to the values they had 
when the dialog box was opened. 
Advanced IP
Figure F-5Assigning IP Information
The  Advanced IP  button in the Show Profile  and Edit Profile  dialog boxes opens another dialog box that allows 
you to configure a static IP address as well providing DNS and  WINS fields so that you can specify DNS and 
WINS resolvers.
Security Configuration
The  Security Configuration  dialog box is accessed through the  To o l s menu. The  Security Configuration  dialog 
box allows you to enable, disable and chan ge the PIN. You will need the current PIN to  make any of these 
changes. The PIN must be enabl ed in order to be changed. (If the PIN is disabled, the New PIN entry field is 
greyed out.)
The  Require PIN  on resume  check box is independent of the aforementioned settings. By de fault, this check 
box is unchecked. While this option remains unchecked, any PIN  entered on startup or through the Security 
Configuration  dialog box and submitted success fully to the modem is stored in memory for as long as the 
device is not rebooted. This s tored PIN is then used without fu rther user interaction whenever the modem 
requires a PIN (such as resume after suspend or modem removal).  The stored PIN is also automatically 
entered in the  Current PIN text box whenever the  Security Configuration dialog box is called up. 
If unauthorized access to the  device is a concern, the Require PIN on resume check box should be checked. 
In this case, the PIN is not store d; whenever a PIN is required, you will be prompted to enter an 
appropriate value.
NOTE Keep in mind that some network o perators do not allow the SIM PIN to be disabled. A new PIN 
must consist of 4 to 8 numeric digits.

Network Configuration
In the main Wireless WAN window:
• Tap on the  To o l s menu, and choose  Network.
Enable Automatic Network Select
By default the GSM radio modem  automatically chooses from the available and allowed networks (allowed 
networks are the home network and  all other networks with which the home network has a roaming agree-
ment). You may find th ere are some situations in which you want to override this default behaviour. For 
example, you may want to disable roaming if you find yourself i n a border area where the home network is not 
available but a foreign roaming partner is available. Abroad, y ou may find that an available network does not 
have GPRS roamin g agreements. In this c ase, you’ll need to manu ally select the networ k which you know to 
support GPRS roaming.
Automatic network selection is  enabled or disabled by checking  or unchecking Enable automatic network 
select  in the  Network  dialog box. When automatic netwo rk selection is disabled, you must select a network 
manually.
Show Available Networks
Available networks can also be vi ewed without changing any settings. Scanning for available networks is a 
lengthy operation — a progress bar is shown while the scan is a ctive. For every network that is found, the 
network name, country,  status and numeric network identifier (M CC/MNC, Mobile Country  Code followed by 
the Mobile Network Code) is displayed.
Configure Frequency Bands
NOTE Your home network oper ator will need to let you know which othe r networks have roaming 
agreements. Even when a network  is listed with an ‘Available’ status, it does not necessarily fol-
low that it can be used or that t he roaming agreement covers GP RS. 
A status of ‘Forbidden’ indicates that the network cannot be us ed. If you choose a network that is 
not covered by a roaming agreement , the status in the main WWAN dialog box changes to 
‘Emergency calls only’, ‘No network found’, ‘GPRS not available ’ or ‘GPRS not allowed’. 
						

							F - 10 Workabout Pro4 (Windows Embedded CE 6.0) User Manual
The network selection can be modified by enabling or disabling GSM and UMTS frequency bands. 
By default all bands supported by  the installed WWAN modem are enabled. All bands that are not supported 
by the installed modem are greyed -out. While some modems (e.g. Cinterion PH8-P) allow all possible combi-
nations of supported bands to be selected, others do not (e.g.  Cinterion MC75i). A warning is displayed if an 
unsupported band comb ination is chosen. 
By enabling only bands in use on a  given network, the network search time (e.g. after losing the network due to 
a coverage gap) is improved. Through the band configuration it  is possible to force the modem into GSM-only 
or UMTS-only mode. As an exampl e, this is useful if a legacy application needs to use a dial-up connection 
and the network supports dial-up connections only on GSM but not on UMTS (as is the case with many Euro-
pean networks). 
Enable Automatic Time Update
If this feature is enabled, it allows the system time and time  zone to be updated with information received from 
the WWAN network. This feature is network-dependent. If the WWA N network supports NITZ (“Network Infor-
mation and Time Zone”), then it can send the current time, time  zone, or both to the terminal.
Driver Mode Configuration 
By default, the Wireless WAN driver is enabled (the Enable driver check box is checked). If the  Enable driver 
check box is not checked, the d river is shut down as soon as th e OK  button in the  Driver Mode dialog box is 
chosen. 
If, on the other hand, the Wirel ess WAN driver is not running a nd the Enable driver  check box is checked, the 
Wireless WAN driver is started as soon the  Driver Mode dialog box is closed using the  OK button. 
Since all currently supported GSM  modems are automatically detected, the Enable automatic port detection  
check box should always be check ed. If this check box is not checked, a serial port can be selected manually. 
This experimental feature allows  the driver to be used with an internal GSM modem that was not recognized by 
the automatic detection or an external GSM modem connected to a  serial port of the computer through USB or 
through  Bluetooth . An external modem connected to a serial port must support 115 .2 kbit/s, 8bit, no parity and 
hardware flo w control.
IMPORTANT Care must be taken wh en disabling bands — the wrong band will p revent the modem 
from registering with the networ k (that is, not even emergency calls are possible if a 
mistake is made). 
NOTE When the driver is not running,  no network status or signal strength can be displayed.

Modem Information
The fields in this dialog box cannot be edited, they only displ ay information about the computer’s modem. If the 
network operator has not programmed a user’s phone number into  his SIM, the Phone: field remains empty. If 
the main menu shows an error status, at least partial modem information may be available.
Diagnostics and More 
The  Diagnostics  screen may be useful when diagnosing network problems. The inf ormation presented here is 
not needed for normal operation. The  More button shows you some additional detail about your modem. 
The following Diagnostics  values are displayed:
Diagnostic 
ValueDescription
MCC Mobile Country Code (decimal v alue and, if available, decoded country name)
MNC Mobile Network Code (decimal v alue and, if available, decoded network name)
LAC Location Area Code (dec imal and hexadecimal value)
CID Cell Identifier (decimal  and hexadecimal value)
TA Timing Advance (decimal value an d converted distance to base station in meters)
BCCH Broadcast Control Channel (AR FCN or UARFCN value and converted frequency in MHz)
BER Bit Error Rate
RSSI Received Signal Strength Indication
TCH Traffic Channel (ARFCN value  and converted frequency in MHz) 
						

							F - 12 Workabout Pro4 (Windows Embedded CE 6.0) User Manual
Note that TA, BER , and  TCH are available only in GSM mode and only while there is an acti ve connection (e.g. 
a voice call). If the status in th e main window shows “No netwo rk found” or “Searching for network”, then typi-
cally only  Batt and Te m p are available. For the status “Emergency calls only”,  MCC, MNC , LAC, CID , and 
BCCH  may be available. For the GSM 1800MHz and GSM  1900MHz bands it may not be possible to convert 
the ARFCN for BC CH and TCH to a frequency because the channel n umbers overlap. This can be overcome 
by enabling only the GSM bands us ed by a particular network (i.e. either GSM 1800MHz or GSM 1900MHz is 
disabled). If the network uses f requency hopping during GSM voi ce calls, then “hopping” is displayed in the 
TCH field.

SMS Menu 
SMS (Short Message Service) func tions are accessed through the SMS menu. For modems that support a 
SIM card, the SIM initializatio n typically takes longer than the network initialization, resulting in a noticeable 
delay before the SMS func tions become available. 
New
Tapping on the New button opens a dialog for sendi ng a new SMS message. The recipient's phone number (to 
be entered in the  To :  field) can consist of the digits  0 through 9, as well as the * and # characters, optionally 
preceded by one + character, indi cating an international number (i.e. the country code follows immediately 
after the + character). 
By checking the  Store message in Outbox  field a new message can be stored in the Outbox before being s ent. 
If no storage space is available,  or the modem does not support  the storage of outgoing messages, then this 
check box is disabled.
Inbox
Tapping on the  Inbox button opens the list of received messages. Reading 50 message s, for example, from the 
SIM can take about 30 seconds. By  default the list of messages is sorted with the most recently received 
message first. The list can be s orted by any other column by cl icking on the corresponding column heading. 
Clicking the same column heading twice reverses the sort order.  Tapping on any letter or digit moves the high-
light to the next message whose a ddress begins with that letter or number. 
The  Open button opens the selected messa ge in a new window such that the entire message can be read 
including the original formatting (line breaks are replaced by spaces in the Inbox message list). Pressing the 
Reply  button opens the new message di alog as described above, except the destination phone number is 
filled in already.
Outbox
Tapping on the  Outbox button opens the list of se nt messages. Otherwise the  Outbox behaves exactly as the 
Inbox described above. The date an d time when a message was sent is not available for GSM modems.
NOTEThe date and time formats can be changed through the Region and  Language menu in Control 
Panel. For a new date or time format to take effect the Inbox h as to be closed and re-opened.
