AFFORDABLE YET
POWERFUL COMBINATION
GM3189 & GM3689 Select V

In today’s fast-moving workplace, efficient communications
solutions are vital to your competitiveness. A misunderstood
message may have big consequences. That is why 75 years of
pushing the frontiers in radio technology makes Motorola the
brand of choice when you need reliable, clear communication.
The GM3189 and GM3689 two-way radios comfortably meet the
level of reliability and clarity needed for industries like Taxis and
Courier services. The rugged build quality, characteristic to all
Motorola mobiles, means they are apt for Construction and
Manufacturing activities too.
Advanced features such as PTT-ID, Emergency and Lone Worker
capabilities are possible with these Select V mobiles.
Furthermore, your investment is protected, as the GM3189 and
GM3689 are compatible with the existing range of accessories.
GM3189: Affordable and Efficient
Communications Solution

GM3189 & GM3689 Select V

Common Features of GM3189 and
GM3689
Signalling Standard
Both mobiles support the following Select V
signalling standards, and programming of up to two
‘user-defined’ signalling standards is possible.
• ZVEI
• Modified ZVEI
• French Modified ZVEI
• 20ms CCIR
• 70 ms CCIR
• 100 ms CCIR
• EEA
Rugged Construction
The mobiles are built to meet or exceed the stringent
Motorola ALT, MIL-STD 810C/D/E and IP54
international standards, which make them suitable
for use in rough environments.
Audio Enhancement
The mobiles offer voice compression mode and
powerful 4W front-firing speakers for maximal audio
clarity. Optional 13W external speakers are available
for high-noise environments like the construction and
manufacturing industries.
User Friendly
• Large ON/OFF Knob and Channel Buttons enable
easy and quick operation.
• Programmable Buttons provide convenient access
to frequently-used functions.
• LED Status Indicators and Alert Tones allow clear
indication of radio’s operating status and timely
notification of incoming calls.
16-pin External Accessory Port
Allows easy expansion of radio’s capability, without
messy dismantling and rewiring.
Devices such as GPS module, data modem and a host
of others can be added on as your business needs
grow.
Industrial Applications
The GM3189 and GM3689 can be used as a
Radio Frequency (RF) pipe for integrated
solutions such as Automatic Vehicle Locator
Systems (AVL) and Telemetry. A host of devices
can be connected via the mobile’s 16-pin
external port, to offer a multitude of solutions.
Automatic Vehicle Locator Systems (AVL)
Allows remote tracking of your vehicle’s
location using the Global Positioning System
(GPS) and integrated software. This ensures a
more efficient utilisation of the fleet, dynamic
planning of delivery routes and estimation of
arrival time, thereby resulting in better
customer service and profitability. The AVL
system can also be used to track vehicles
carrying precious cargo and company personnel
in high-risk environments.
Telemetry
Enables remote real-time monitoring of
environmental conditions or equipment
parameters. Together with integrated hardware
and software solutions, the mobiles can be
used for remote monitoring of water levels in
inaccessible areas, or to track key operational/
process parameters to ensure the safety of
plant workers.
PTT - ID
Identifies the radio during transmission. This saves
the need of verbal identification, making
communication more efficient.
Lone Worker
Provides added safety to users who work alone. The
radio enters into Emergency mode if the user fails to
respond to a warning signal after a stipulated time.
Stun/Unstun
Prevents abuse of the radio network. The central
dispatcher can disable unauthorised or nuisance
users over the air.
Emergency
Activates the emergency mode via the footswitch,
allowing the driver to notify the central operator
quickly and discreetly in an emergency situation.
Voice Operated Transmission (VOX)
Radio may be activated by voice control when
connected to a Visor microphone, thus allowing users
to concentrate on road safety.
