mode, memory programming and recall, channel scanning, etc. In
general terms, to recall/change settings for various functions:
1. Press the
F (Function) key repeatedly to scroll through the
available functions, until you nd the one you want.
2. Press the
o buttons to set the function currently on the screen.
Depending on the function, you can select

Off (function deactivated), or scroll through the various values
(e.g., from 01 to 06

3. To store a changed setting, press either the

Both will perform the same operation, the difference being that
the

function.
After following step 1, you must make any changes you wish
to within 10 seconds of each button being pressed, otherwise
the radio will return to standby and will store with the current
settings.

6.2 VOX mode
VOX (Voice Operated eXchange) enables the user to activate hands-
free transmission (without pressing any buttons) simply by speaking
into the microphone (7). This way, the user is able to rest the radio
on a nearby surface and still be able to communicate without picking
up the radio.
VOX functions best with the optional audio accessories which
connect to the
SPK and MIC PTT jacks. By using these accessories,
the microphone will always be close to the user’s mouth, and apart
from the convenience of being hands-free, this will give the user an
even greater range of movement, especially with the radio clipped
onto the user’s belt.
