Motorola Gm300 Selling Manual

							5 Tone (Select 5) Decoder2-33
If the received telegram does not have address digits, the call is not placed in the Missed Calls List.
If a second call occurs from a radio ID already stored in the Missed Calls List, only the most recent
information is stored.
The Missed Calls List can support up to 10 entries. If the Missed Calls List is already full and
another unanswered call occurs, the radio can be programmed to either:

Discard the oldest call entry, or

Not enter any new calls.
If the Missed Calls List has entries, the Missed Calls List icon is illuminated. If one or more new calls
have been added since the last time the Missed Calls List was displayed, the Missed Calls List icon
flashes.
The Missed Calls menu can be accessed via the menu navigation buttons or a programmable
button. However, if the Missed Calls List is empty, the Missed Calls menu is not available. Missed
Calls are displayed on a last in first out basis. They can be viewed and deleted from the Missed Calls
List.
The currently selected Missed Call can be answered by pressing any button programmed as Fixed
Telegram. The radio ID stored for that entry is entered in the telegram, then transmitted.
For Advanced Multicall users only, the currently selected Missed Call can be answered by pressing
any button programmed as Address Send. The radio ID stored is entered in the telegram number
stored, then transmitted.
The tick and hash buttons serve as Fixed Telegram or Address Send buttons, if so programmed.
There must be the correct number of radio ID digits for the selected telegram’s Variable Digits. An
incorrect number of digits results in an error tone.
When the Missed Call is answered, the Missed Calls menu is exited, and the call is deleted from the
Missed Calls List.
The Missed Calls List is remembered over radio power down.
If Call Forward has been enabled, the calls are not stored in the Missed Calls List of the forwarding
radio.
Benefits

The user knows who has called if they are unable to answer calls for some reason.

The caller’s ID is stored even if another call is received.

The user can answer calls when it is convenient for them.

The user does not have to answer the calls in the same order that they were received.

							2-34FEATURES AND BENEFITS
13.0 Additional Decode Functions
In addition to individual and group call alerts, the functions available to be activated on successful
decode are:
13.1 Start Auto-Reset and Stop Auto-Reset (Cleardown)
The Auto Reset Timer can be started and stopped by decode of a 5 tone sequence.
Start Auto Reset decode starts the auto reset timer and opens the squelch so that voice messages
are heard. Stop Auto Reset decode (“Cleardown” or “Remote Close”) ends the auto reset timer and
returns the radio to the “Receive Squelch” so that the radio is squelched.
Start Auto-Reset and stop Auto-Reset are used to “authorise” and “de-authorise” the radio when
operating in Authorisation.
Benefits

Automatically opens squelch so that radio user can hear incoming voice message.

Automatically closes squelch, to prevent user from hearing unwanted messages.
13.2 Authorisation
Authorisation allows the central dispatch to control call set up and monitoring activity. Only
authorised radios can make calls or monitor channels. The only call a de-authorised radio can make
is the request for authorisation to a pre-determined destination.
In order that the user can be confident that their call has been received by the base, the base sends
back an acknowledgement beep for a short period. To allow the mobile user to hear the
acknowledgement beep, the “Monitor Timer” is be set to open the radio’s squelch automatically for a
few seconds.
On receipt of the request for authorisation call from the mobile, the base, when ready, sends back
an authorisation call. The mobile becomes “Authorised” when it receives this call: the squelch opens
and the PTT allows the mobile user to talk with the base.
At the end of the conversation, the radio is sent a “De-Authorisation” 5 tone sequence from the
base, to reset it back to the de-authorisation state.
It is possible for the base to authorise a whole group of radios, if “Conference Calling” is required.
Benefits

Complete control of radio usage within a team, especially useful for supervisors.

Enables central dispatcher to deal with calls on priority basis.

Enforces good system discipline.

Prevents users from listening to sensitive conversations.

Reduced time wasting leading to increased productivity.

Efficient use of air time. 
						

							Additional Decode Functions2-35
13.3 Stun / Unstun
Stun/Unstun can only be activated by the system manager or administrator.
A 5 tone sequence is sent to a radio which, on decode, causes it to stop working: the buttons do not
function and it will not transmit or receive audio.
This feature can be used to stop a radio working in case:

The radio is stolen;

Hire radios are not returned or payments not made;

A user abuses communication protocols.
The radio can only be unstunned, i.e. returned to operational use, by an unstun signal sent from the
system administrator or returning the radio for reprogramming.
Benefits

Over-the-Air Stun prevents fraudulent or illegal use of the radio.

Render stolen radios unusable.

Disableunreturnedhireradios.

Disable lease radios if monthly payment not received.

Over-the-Air reset of stunned radios eliminates need to bring radio to base.
13.4 Auto-Acknowledge Features
When the GM300 Series radio decodes one of its 5 tone sequences, it can be programmed to
automatically send back a 5 tone telegram. This provides an (audible) 5 tone response to the calling
radio, so that they know that their call has been received.
The radio can decode the auto-acknowledge sequence. Most 5 tone systems use this to automate
calls from the central dispatcher. If the dispatcher console does not receive the expected
acknowledge, the call is resent to the mobile –Telegram Repeat.
It is possible to incorporate “Status” within the auto-acknowledge telegram. It is therefore possible
for the central dispatcher to “interrogate” the mobile radio to find out the current status of the mobile
vehicle operator. This of course assumes that the operator remembers to update the Status number
as appropriate.
The auto-acknowledge feature is highly flexible, to enable the radio to work in a wide variety of 5
tone systems. Up to 16 different acknowledge replies can be set up, each with different encode
telegrams and other features such as making the radio wait until the channel is free before sending
back the auto-acknowledge telegram, sending the telegram on a pre-defined channel, and turning
off the usual side tones and LEDs associated with Auto-Ack operation.
An auto-acknowledge telegram may be sent prior to the radio invoking a call forward telegram.
Benefits

Auto-Acknowledge can be used to automate calls from the dispatcher.

Auto-Acknowledge with status allows dispatch to integrate the radio.

High degree of system flexibility is possible.

“Silent Interrogate” or “Radio Check” is possible (turn off side tones/LEDs). 
						

							2-36FEATURES AND BENEFITS
13.5 Call Forward
Feature
Call Forward allows calls to be forwarded to a portable radio, a 5 tone pager or another radio user.
This can be used if the user is away from the vehicle, or does not want to be disturbed.
Benefits

Enables re-routing of calls when user is away from vehicle.

If you really cannot be disturbed, e.g. in a meeting, your calls can be answered by somebody
else.
13.6 Emergency Calls
Emergency is useful if a user is in a potentially hazardous situation, such as risk of hijack or hostage
situation (taxis and police). A single button press establishes immediate communication with a pre-
defined person or group of people. Emergency calls are prioritised by the radio system and by pass
all normal system protocols.
Emergency can be activated by pressing a button or switch with the feature programmed to it. The
Emergency feature can be programmed to any of the programmable buttons, or inputs on the
accessory connector. If an emergency switch is connected to pin 9 of the accessory connector and
the radio is turned off, pressing the switch will turn the radio on and immediately put it into
emergency mode: seeemergency wake upin the accessory connector section.
13.6.1 Emergency Cycles
When in emergency mode, the radio cycles through periods of transmission (TX) and reception
(RX), to allow the central dispatcher (base) to hear activity in the vicinity of the radio, and to then
allow the radio user to hear messages from the base. This is automatic due to the assumption that
in the emergency situation, the radio user is probably unable to press and release the PTT button.
The duration of the TX and RX periods within the cycle is dealer programmable.
Limited Number of Cycles:
The number of TX/RX cycles can be dealer programmed as a fixed number, or to carry on until the
emergency mode is reset (see later).
TX Cycle: Tone / Tone & Voice
Optionally, a special “alarm” tone can be transmitted along with any sounds picked up by the
microphone. This alarm tone is at a low level, so that voice messages from the mobile radio user
can still be heard by the central dispatcher, but is distinctive so that all radio users on the channel
are immediately aware that they are listening to an emergency transmission.
NOTEThe microphone must be a ‘hot’ mic for its audio to be transmitted. In a ‘hot’ mic, the
PTT is not in series with the mic, and the radio can put the mic into transmit mode.
The enhanced compact mic, MDRMN4025, is a ‘hot’ mic. 
						

							Additional Decode Functions2-37
TX Cycle: Telegram
A special 5 tone emergency telegram can be transmitted, to activate emergency mode on the
central dispatcher’s equipment (e.g. Centro Plus desktop controller). This telegram can also contain
Status information.
TX Cycle: Voice Message
An emergency message can be pre-recorded which is sent automatically when the emergency call
feature is activated. This message can contain, for example, the user’s location or status which
would be useful to the recipient, especially if the user is unable to talk.
Refer to Voice Storage to use this feature.
13.6.2 On/Off Switch Enable
The On/Off switch can be programmed to be operational or non-operational when in Emergency
mode. If the On/Off switch is enabled, then when in standard emergency, it is possible to turn the
radio off (and therefore reset the emergency mode). If the On/Off switch is disabled, it is not possible
to turn the radio off. See Power Off Logic section.
13.6.3 Secret Emergency
The radio can be set to “Secret Emergency” . The display and LEDs turn off, the alert tones and side
tones are not generated and the audio is muted; the radio appears to be turned off, even though it is
in fact transmitting and receiving.
In “Standard Emergency” the display, LEDs and alert tones function as in normal radio operation
and they change if the radio changes channel or transmits as part of the emergency operation.
13.6.4 Emergency Squelch
The Emergency Squelch can be set different from the standard squelch setting.
13.6.5 Emergency Debounce
In order that the emergency mode of operation is not entered into by accident, it is possible to
programme the period of time that the emergency button must remain pressed, before the radio
enters emergency mode.
13.6.6 Emergency Revert Channel
A default emergency channel can be specified, so that the radio changes to this channel during the
emergency transmission and reception.
13.6.7 Emergency Microphone Source
The microphone source during TX periods is dealer programmable. It can be either the standard
microphone (which will work even if the PTT is not pressed), or an external microphone wired into
the 16 pin accessory connector. This external microphone can be hidden within the vehicle to avoid
the possibility of an attacker being able to disconnect the working microphone (even if the standard
microphone is ripped out, the radio can still transmit because it is using the hidden microphone). 
						

							2-38FEATURES AND BENEFITS
13.6.8 Emergency Microphone Gain
It is quite likely, especially if a hidden emergency microphone is used, that the speech level will be
lower than normal operational situations. Therefore, a special microphone gain can be set for
emergency operation, to amplify quiet sounds.
Incoming emergency calls are unique and easily identifiable.
13.6.9 Exiting Emergency Mode
Emergency mode can be exited by:

Completion of a limited number of transmit receive cycles;

Turning the radio off;

Power is removed from the radio;

Receipt of a 5 tone Emergency Reset sequence – stops the emergency cycles and
returns the radio to normal operation.
13.6.10 Incoming emergency
Incoming emergency calls are decoded by the radio. A unique and easily identifiable alert is
sounded.
Benefits

A single button press initiates automatic radio operation in situations where vehicle driver is
unable to operate radio as normal.

Immediate and guaranteed communication with your team when you need it most in an
emergency situation - no unpredictable infrastructure delays.

Emergency TX/RX cycles allow other radio system users to hear what is happening at the
emergency site, and to talk to the radio user.

Secret Emergency provides “covert” communications for sensitive situations.

Highly flexible configuration to match radio user requirements.

Emergency reset enables central dispatcher to reset radio remotely from emergency mode.
13.7 Lone Worker
Lone Worker is a special form of Emergency mode. The feature enables individuals to work alone
with added safety. The radio continues to operate as normal providing the radio buttons are pressed
regularly. However, if none of the radio buttons are pressed for a pre-determined amount of time, the
radio sounds a distinctive reminder to prompt the user to press one of the buttons.
If after a further amount of time, the radio user still has not pressed any of the buttons, the radio
concludes the operator is in need of assistance and automatically makes an emergency call to a
pre-determined contact number.
The operation is flexible and can be tailored to meet specific customer requirements.
The Lone Worker Response time can be set from 1 to 255 minutes, giving sufficient time for a driver
to leave his vehicle, check a premise and return to the vehicle. The driver could leave a voice or
status message stating where he is going, so that if he does not return to his vehicle the location is
transmitted in the emergency call.

16.0 Installation
16.1 Control Heads
The control head on the mobiles can be disconnected from the transceiver eg for remote mount
installation. It must be noted that although the control heads on different models of mobile are
physically interchangeable, the software functionality is NOT interchangeable; for example, a
GM360 control head will not work on a GM340 transceiver, or via versa.
16.2 Remote Mount
Each of the mobile radios can be installed in a remote mount configuration. The control head and
transceiver are separated, and reconnected via a length of cable. This allows the head to be
mounted where it can be seen easily and the transceiver to be mounted somewhere else eg the car
boot. This is useful if space is limited, and also reduces the probability of theft.
The cable to connect the control head and transceiver is flat 8 wire telephone cable with small
telephone telco connectors on the ends. As the connectors are so small, the cabling can be routed
through the vehicle more easily, usually using just the conduits normally available and not having to
drill any extra.IMPORTANT:
If the wrong control head is connected to the transceiver, the
radio will not work!
