GMRS Mode Programming

The GMRS (General Mobile Radio Service) feature is a land- mobile service available for short-distance, two-way communications in the USA. You must have a valid FCC license to communicate on these channels (see page 28).

Start from GMRS Standby mode to begin GMRS Setup programming. Press and hold the Call/Enter/Setup button for two (2) seconds to enter the programming mode.

CTCSS and DCS Coding Mode

Continuous Tone Controlled Squelch System (CTCSS) and Digital Coded Squelch (DCS) coding are used in two-way radio systems. These are sub-audible frequencies or digital tones that are sent continuously with speech to engage other radios with this feature. This feature is generally used between talk groups on shared channels. Only radios with the same subcode set will hear your transmission.

To Set CTCSS Code Entry:

1.The CTCSS code entry mode is the first mode that begins the GMRS Setup programming.

2.Display will show CTCSS icon and OFF icon flashing.

NOTE

If CTCSS was previously set to a Code number, display will show the current GMRS channel and flash the CTCSS icon and Code number.

3.Codes begin at 01 and go to 38, followed by OFF, and return back to 01 again. The last used GMRS channel will be shown in the large digit display.

NOTE

If CTCSS is On, then DCS must be Off. If DCS is On, then CTCSS must be Off.

4.Press Channel Up/Down button to change code number, or press and hold Channel Up/Down button to rapid advance (scroll).
