Radius GR1225 Repeater 2-Way Radios The GR1225 Repeater relays both 12.5 kHz and 25 kHz. And Motorola made it hard to hear a difference. Attractive, trim, versatile, the GR1225 is loaded with advantages, and savings are the direct result of its simplicity. This latest innovation in design not only eliminates one of the internal mobile radios and the basic repeater controller that modular repeaters require, it cuts the cost to build a repeater by nearly a third. This more stylish, compact, desktop unit relies on a single, fulL duplex transceiver to transmit and receive. The GR1225 is ideal for desktop use in an office setting. It can also become a base station allowing a desktop operator to communicate with other radios in the field. It has built-in basic repeater capabilities. Optional controllers can be added for enhanced features such as telephone interconnect, multiple codes and signalling. Compact styling makes it ideal for desktop use. You may be used to conventional repeaters that dominate whatever space they're relegated to within the office environment. The GRI225 accommodates a built-in power supply as well as numerous internally-housed accessories. With the capacity to house options like duptexers, battery revert and an enhanced controller within, the modest space it occupies is even more impressive. This repeater comes standard with two PL or DPL squelch codes per channel. With both a transmit and receive code per channel, the GR1225 prevents transmissions over your repeater without proper I.D. or "squelch codes". You set the Time Out Timer to 1-255 seconds or off, if desired. This automatic shut-off feature prevents a group from monopolizing the repeater with a single transmission. This equitable feature governs the unit itself when used as a base station.

The Battery Back-Up Tone sends a warning. When the battery revert kit is installed, this heads-up alert notifies users during conversations that they're using the back-up battery supply for the GR1225.

Power is adjustable by channel. Each channel can be programmed to a different power level - either 25 or 45 (UHF) and 25 or 50 (VHF) Watts to meet your coverage needs no matter how varied. Warehouse and taxi companies set to low power for continuous communication for a distance of up to 20 miles. Delivery truck companies might set to high power for less frequent communication of up to 40 miles.

Because of CWID, you don't have to I.D. yourself. Continuous Wave Identification uses Morse Code to automatically send out the station ID periodically to identify the owner of the transmitting repeater. This satisfies the requirements of the FCC.

The AdvantagePort allows expansion of the GR1225's capabilities under full protection of its original warranty. Your dealer can quickly and safely install a wide range of capabilities to meet unique customer needs.

Courtesy Beep signifies when a person is through talking. You don't have to say "over" to complete your transmission - the other people in the group are now clearly free to talk or respond.

Relay Delay keeps the repeater transmitter keyed a short time after a radio user releases the PTT switch. This allows a user group to conduct a normal conversation without delays from re-activating the repeater. This "polite pause' or Relay Delay can be set from 0 to 7 seconds.

Conversion Kit. Allows you to use the R1225 transceiver to create a 12.5/25 kHz switchable repeater for rack mount or wall mount applications.

X-Pand lets you gradually migrate to the narrower bandwidth and still preserve audio quality. X-Pand technology actually compresses your voice at transmission. At the receiving end, it expands it while simultaneously reducing extraneous noise. X-Pand technology at 12.5 kHz can actually out perform 25 kHz sound quality and is available only in the Motorola Radius 1225 series.

Optional Accessories

Duplexer. Can be internally installed to allow a single atenna to be used instead of two separate antennas to transmit and receive simultaneously.

Portable Carry Case. Allows easy transport for use as a back-up or emergency repeater.

Desk Microphone. This converts a desktop repeater into a dispatch radio for office or personnel use.

C100 Desk Set. DC or Tone Remote model allows user to control a remotely located repeater. Extended Local model provides base station control for dispatch operations. RapidCall model provides the dispatcher with features such as Push-to-Talk ID, Emergency Alarm Decode, Call Alert, Radio Check and Voice Selective Call.

Battery Revert. Automatic back-up power allows continued use when power goes down. Also includes float maintenance charger to keep battery charged when not in use.

One of the following controllers can be installed inside the repeater to provide enhanced features...

i20R Onsite Repeater/Controller. Provides up to 10 PL/DPL single code or cross code combinations for multiple group repeater operations, remote knock-down/set-up, uni/bi-directional capabilities and CWID.

ZR310 Multiple Tone Community Repeater Controller. Provides up to 50 PL and 20 DPL single code or cross code combinations with CWID and enhanced community repeater operation capabilities.

ZR340 Advanced Interconnect Controller. Provides advanced telephone interconnect capability with stored telephone numbers, access/override codes, dialing restrictions, call timers, direct-air access and CWID.

i750R Advanced Selective Calling Interconnect Controller. Provides revertive PL/DPL/Quick-Call II/MDC-1200 group or individual selective calling and advanced interconnect capabilities.
