Motorola 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.
