Just in case these radios have been modified, or have lost there settings, please perform the following:
All radios must be tuned to the same channel and privacy code to communicate. To successfully communicate using a privacy code, both the sending and receiving radios must be tuned to the same channel and to the same privacy code system (CTCSS or DCS) and privacy code number. Each channel will remember the last privacy code system and number you select.
The privacy code 00 is not a privacy code, but allows all signals to be heard on a channel that is set to 00 on both the CTCSS and DCS systems.
Channels 1 through 7 are shared with FRS/GMRS. Channels 8 through 14 are FRS only.
Channels 15 through 22 are GMRS only.
To select a CTCSS privacy code:1. After selecting a channel, press the Mode/Power button until the CTCSS icon appears and the small numbers next to the channel number flash on the display. If DCS is turned on at the channel selected, the display will flash the CTCSS icon and "OFF." To switch from DCS to CTCSS, press the Channel Up or Channel Down button while the display is flashing "OFF." The display will then show the small numbers flashing and you will then be able to proceed to step 2.
2. Press using the Channel Up or Channel Down button to select a privacy code. You can hold the Up or Down button for fast advance.
