Resetting the Standard Product Default Settings:
Current Application Work Group
If you aren’t sure what programming options are in your image scanner, or 
you’ve changed some options and want the standard product default settings 
restored, scan the 
Standard Product Default Settings: Current Application 
Group bar code below.
The Menu Commands starting on page 10-6 list the factory default settings for 
each of the commands (indicated by an asterisk (*) on the programming pages).
Note: Scanning...

Using the Image Scanner with Bluetooth Devices
The 3820/3820i image scanner may be used either with the 2020 base or with 
other Bluetooth devices.  Scanning the Non-Base Bluetooth Connection bar 
code below allows the image scanner to be used with other Bluetooth devices 
(e.g., PDA, PC - Bluetooth USB Adapter).  After you scan the bar code below, 
follow the instructions supplied with your Bluetooth device to locate the image 
scanner and connect to it.  If you go out of range with your image...

and then set the time-out duration (from 0-3000 seconds) by scanning digits on 
the Programming Chart inside the back cover, then scanning Save.  Default = 0 
sec (no alarm).
Note: If you are out of range when you scan a bar code, you will receive an error 
beep even if you do not have the alarm set.  You receive the error beep 
since the data could not be communicated to the base or the host.
Alarm Sound Type
If you have set the out-of-range alarm enabled, you may change the alarm type 
for the...

Batch Mode Transmit Delay
Sometimes when accumulated scans are sent to the host system, the transmis-
sion of those scans is too fast for the application to process.  To program a 
transmit delay between accumulated scans, scan one of the following delays.
Note: In most cases, a short (250 ms (milliseconds) delay is ideal; however, 
longer delays may be programmed.  Contact Technical Support (page 
15-1) for additional information.

3820/3820i LED Sequences and Their Meaning
2020 LED Sequences and Their Meaning
The base contains a red LED that indicates the status of the unit and verifies its 
communication with the host system and a green LED that indicates image 
scanner battery charge condition.LED Indication Beeper Indication Cause

The tables below list the indication and cause of the LED illumination and beeps 
for the 2020.
Note: Charging only occurs with external power applied to the 2020 or 12 volt 
Host power.
Basic Operation of the Cordless System
Cordless Base
The cordless base provides the link between the cordless image scanner and 
the host system.  The base contains an interface assembly and an RF commu-
nication module.  The RF communication module performs the data exchange 
between the cordless image scanner...

RF (Radio Frequency) Module Operation
The cordless system uses a state-of-the-art two-way Bluetooth radio to transmit 
and receive data between the image scanner and the base.  Designed for point-
to-point and multipoint-to-single point applications, the radio operates using a 
license free ISM band, which sends relatively small data packets at a fast data 
rate over a radio signal with randomly changing frequencies, makes the cord-
less system highly responsive to a wide variety of data...

Out of Range and Back into Range with Data Accumulation Mode 
On
The image scanner may store a number of symbols (approximately 500 UPC 
symbols, others may vary) when out of range and then send them to the base 
when back in range.  You will not hear a communication error beep in this mode, 
but you will hear a short buzz when you pull the trigger if the radio communica-
tion is not working.  Once the radio connection is made, the image scanner pro-
duces a series of beeps while the data is being...

2. Disconnect the keyboard cable from the back of the terminal/computer.
3. Connect the 
appropriate 
interface cable 
to the base and 
to the terminal/
computer and 
keyboard.  Make 
sure the cables 
are secured in 
the wireways in 
the bottom of 
the base and 
that the base 
sits flat on a 
horizontal 
surface.
4. Turn the terminal/computer power back on.
5. Program the base for the keyboard wedge interface.  See Keyboard Wedge 
Connectionon page 1-21.)
6. Verify the base operation by scanning a...

Reading Techniques
The image scanner has a view finder that projects a bright red aiming beam that 
corresponds to its horizontal field of view.  The aiming line should be centered 
horizontally over the bar code; it will not read if the aiming line is in any other 
direction. 
 
The best focus point for reading most code densities is about 5 inches (12.7 
cm) from the unit.  To read single or multiple symbols (on a page or on an 
object), hold the image scanner at an appropriate distance from the...
