The factory has pre-programmed all the UHF CB channels into the
Open SCAN channel memory.
However, you can change or customize the channels by this menu.
To remove the channel from memory, press up or down in this menu.

5 Selectable Call Tones
You can select from 5 call tones. This is the tone that is emitted when
the PTT is pushed 2 times within 1/2 a second.
Current regulations require calling tones to be restricted to one
transmission per minute. If a second transmission is attempted
within one minute, then an error tone will sound.
Scramble
Scramble enables private communications by scrambling the voice
signal.
This prevents users without descrambler equipment or a compatible
unit, from understanding the conversation.
Select desired channel. SCR appears when scramble setting from off
and 1 to 5.

To enable or disable the “Key lock” Function:
Turn radio off. While holding Menu button turn the Radio on.
When the key lock is active, a warning beep will be heard if you
attempt to press keys (except for the PTT button).
