ICOM IC-F31GSN
ADVANCED VHF PMR HANDHELD TRANSCEIVER
256CH - WITHOUT KEYPAD

The IC-F31GS is the latest range of advanced hand portable transceivers, launched by Icom, aimed purely at systems.

Incorporating good design
and featuring a large capacity for expansion, the new IC-F31GS contains a wide range of built-in features including 256 channel capacity, a 2-line-LCD display, , narrow 12.5kHz channels, multiple tone signalling standards, Flash-ROM and high speed PLL.

This makes it
the ideal transceiver for small systems as well as large, wide area networks.

The strength of the IC-F31GS
is its versatility. The IC-F31GS is designed on a Flash ROM platform, which enables future system upgrades and future compatibility with other protocols.

Featuring state-of-the-art
RF technology including a newly designed Fractional-N™ PLL system, the ultra high-speed circuitry provides stable data communications.

A new speech compressor
(Audio Compander function) provides crystal clear audio under noisy conditions.

See accessories table

The IC-F31GS has a variety of signalling standards built in, including CTCSS, DTCS, 2 Tone, 5 Tone and DTMF.

Both encode and decode functions are also built in.
ANI (Automatic Number Identification) identifies the unit in use with the appropriate dispatch equipment.

Two levels of voice scrambling are available to safeguard your transmissions.

You can choose either the UT-109 Simple Inversion module or the more secure UT-110 Rolling Code module.

The LCD Display is large and easy to read. Utilising full dot matrix characters of up to 2 lines, the user can create a sentence of up to 24 characters. You can also display your own personal icons, programmed from a PC.

The Man Down feature (optional UT-113 required) is an important safety feature for lone workers in potentially dangerous situations. Two internal option slots, not available previously on Icom commercial radios, allow you to combine optional features such as scramblers and man down facilities.

The IC-F31GS features 256 memory channels, which may be selected from either the keypad or the rotary knob. Further customisation of the transceiver may be gained from eight programmable keys, each of, which can be assigned one of 27 different functions.

The IC-F31GS features an attractive ergonomic design. The body is compact and meets MIL STD grade C, D and E for shock and vibration.

Included with each radio are a rapid charger, belt clip, comprehensive handbook and a NI-MH rechargeable battery (which is designed for 10 hours operation). To give added confidence each model has a 1-year warranty. A comprehensive list of accessories is also available.
