Motorola GR1225
Solves Coverage Issues Quickly and Easily

You can have X-Pand and all the advantages of a Motorola Repeater with the GR1225. With 16 programmable channels, you can talk on either a 25 or a 12.5 kHz channel allowing a seamless, economical transition to the narrower bandwidth. Two-way users won't want to be without this greatly expanded audio quality at 12.5 kHz. The GR1225 makes a perfect complement to the 1225 Series Two-Way Radios.

GR1225 Features

The GR1225 has the following features:

• 12.5/25 kHz Switchable Channel Spacing - with X-Pand Technology
• Compact Styling - The GR1225 accommodates a built-in power supply as well as numerous internally housed accessories such as a duplexer, battery revert and an enhanced controller.
• Adjustable Power - Each channel can be programmed to either 25 or 45 (UHF) or 25 or 50 (VHF) watts to meet various coverage needs.
• 2-Character Numeric LED Display - Green light illuminates the channel that's in use.
• Battery Back-Up Tone - When the battery revert kit is installed, it alerts users that they are operating on the back-up battery supply.
• Time-Out Timer - Programmable from 1-255 seconds, this feature prevents a group from monopolizing the repeater with a single transmission.
• Repeater Enable/Disable - Temporarily enables or disables repeater operation from the front panel to allow use as a base station for dispatch operation.
• CWID (Continuous Wave Identification) - Continuous Wave Identification uses Morse code to automatically send out the station ID to identify the transmitting repeater.
• Courtesy Beep - This programmable alert indicates when a person is through talking so that other users are free to respond.
• Programmable Relay Delay - This “hangtime” keeps the repeater transmitter keyed from 0 to 7 seconds after the radio user releases the Push-to talk switch to enable other users to respond without having to re-activate the repeater.
• AdvantagePort Expandability - Allow an authorized dealer to add an Advantage Board to upgrade the repeater functionality.
