Whether you want to improve your logistical control over a fleet of vehicles, or to increase the safety of your personnel when on the move, the GM350 offers a great communications solution. With a choice of two models, the GM350 combines Motorola's traditional reliable performance with breakthrough features, giving enhanced communication effectiveness.  User features from the wide range below can be selected to match your specific requirements to provide easy to use, flexible, long lasting communications.

GM350 Standard Features

• Internal Loudspeaker with 4 W audio power 
• Private Line (CTCSS) and Digital Private Line
• Programmable Time Out Timer and Re-Key Timer
• Single Tone Encode for repeater access or limited selective calling
• Single Tone Decode for limited selective calling (128 ch display models)
• Programmable Power 5-25 W, set per channel from 2 programmable levels
• Choice of 12.5 kHz or 20/25 kHz models 
• Ultra-Wide frequency range for maximum system flexibility
• Plug in modules for enhanced functionality Data mode (128 ch display models)

Other Standard Features

Fully Field Programmable All the operational parameters of the GM350 can be field programmed by an IBM PC or compatible computer, using advanced programming software employing a graphical user interface, running Windows or DOS operating systems.

Up/Down Volume Control The elimination of rotary volume controls results in increased radio reliability and higher overall quality at a lower cost.  The GM350 volume control is easy to use and functions just like a cellular telephone volume control.

Installation Flexibility The slimline design and small size of the GM350 provides for maximum ease of installation in all types of vehicles - even those with minimal space.  Also, the control head can be "reversed" to ensure that the user always sees the display the right way up. An optional DIN slot bracket provides a neat installation solution.

Busy Channel Lockout Using the optional busy channel lockout function will greatly improve your communications efficiency and reduce user annoyance, especially on community repeaters, as this function prevents different user groups from transmitting "over" each other.

Ignition Sense For users where it is important that the GM350 is powered up and functional whenever the vehicle ignition is on - without the user having to remember to turn the radio on - the ignition sense facility is perfect.  Combining this feature with the optional "designated power up channel" means that whenever the vehicle is started up, there is no danger that the radio will be on the wrong channel and miss vital messages. Also, use of ignition sense is a great way to avoid dead batteries on vehicles that are left standing between operational use.  It's ideal for vehicles in the emergency services.

Dealer Programmable Function Buttons To provide maximum flexibility, and ensure the operation of your GM350 radios to match your individual operational requirements, you may select a number of useful features to be assigned to the function buttons.  Non-Display (4 channel) radios have two function buttons, while Display (128 channel) radios have six function buttons.
Standard Function Button Options on  all Models

Repeater Talkaround In situations where it is not required, or desirable to communicate via a repeater, Talkaround turns the radio into simplex radio for back-to-back communications.  In addition, it's a vital feature to ensure continued communications when unforeseen circumstances cause a repeater to go out of service.

Dual Level Monitor Any option button can be dealer programmed to offer up to two levels of monitor operation, such as carrier squelch then open squelch (volume set).

Single Tone Encode In addition to having an automatic single tone encode sent whenever the radio transmits, to access a repeater, it is possible to also configure a function button to send a single tone, for manual repeater access.

Function Button Options on 128 ch Model with Display

Scan The GM350 supports up to 2 scan lists, each of which can be assigned to any of the function buttons.  Both scan lists can include one priority channel that will be monitored for activity even if the radio is receiving on another channel.  The scan lists are dealer programmable - however users may temporarily delete unwanted channels from a scan list using a "nuisance channel delete" function button. Several options for transmit operation in scan mode are available:

Talkback: Transmit on the channel that is currently used for receiving

Home Revert: Transmit on the channel displayed prior to entering scan mode

Last Free: Transmit on the most recent channel that was free of activity

Last Busy: Transmit on the most recent channel that was busy

Designated Channel: Transmit on a pre-defined channel
Memory Channel Button Up to two function buttons can be dealer programmed as "memory channel".  The GM350 user can store any channel in the memory button in the same manner as modern FM car radios.  Rapid access to important channels such as an emergency channel is then available at the press of a button.

Scrambler Related Functions The 128 channel GM350 option module interface supports the use of voice scramblers.  When a suitable scrambler module is installed, one function button can be dealer programmed to provide selection of  "coded speech/clear speech" and another button to provide a "scramble key select" function.

Accessories

DIN Mounting Bracket Allows the GM350 to be neatly installed in a spare mounting slot often provided in vehicles.

Remote Mount Kit Allows the control head to be mounted on the dashboard, where the radio unit is installed elsewhere (i.e. in the car trunk).  This overcomes the problem of restricted space and reduces the risk of the radio being stolen.

Desktop Operation

The GM350 may be mounted in a free-standing tray and used in conduction with a desktop microphone. Suitable for dispatch operations.

Audio Accessories

External Loudspeaker A low cost speaker with 13W of power provides enhanced volume for high ambient noise applications
DTMF Microphone Enables use of the GM350 in systems requiring phone patch capability, and also is used in Selectone Smartrunk II systems. 
Handset The optional telephone style handset accessory may be used instead of the standard hand microphone to provide privacy on conversations - whenever the handset is picked-up, the radio's loudspeaker is disabled, ensuring that only the handset user can hear the received message.
