Once the scrambler has been activated your transmission and reception will only be intelligible to others
using the same scrambler technology.
To enable or disable the voice scrambler:
1. Press and hold the key to enter the Menu.
2. Press the key repeatedly until ‘ENCxx’ is displayed (where xx = ON or OF).
3. Press the key to enable the scrambler encoder. ENCON will be displayed.
4. Press the key to disable the scrambler encoder. ENCOF will be displayed.
5. Press the PTT to exit the Menu.
MINIMUM VOLUME
When the volume control is adjusted to minimum there is still sufficient volume to be heard in a
quiet environment. This minimum volume level can be adjusted.
To adjust the Minimum Volume
1. Press and hold the key until the radio beeps.
2. Press the key repeatedly until ‘VMINx’ appears (where ‘x’ is a value from 1 – 9).
3. Press the key to increase the value or press the key decrease the value. A higher
value results in a higher level of minimum volume.
TIP: If there are no signals present to help with the minimum volume adjustment, briefly press the
Squelch key to open the Squelch. You can then adjust the minimum volume while listening to the
receiver noise.
NOTE: There will always be some audible output at the minimum volume setting even when VMIN is
set to the lowest value. It is not possible to set the minimum volume to 0.
DISPLAY CONTRAST
To adjust the Display Contrast
1. Press and hold the key until the radio beeps.
2. Press the key repeatedly until ‘CONTx’ appears (where ‘x’ is a value from 1 – 9).
3. Press the key to increase the contrast or press the key decrease the contrast.
DYNAMIC VOLUME CONTROL (DVC)
The modulation levels of signals heard on the UHF CB band may vary considerably resulting in
noticeable differences in received audio volume between stations. Generally users have compensated
for this by adjusting the Volume control for each incoming signal. With the introduction of 80 channel
narrowband transmissions, the variation in received audio volume caused by the mixture of wide and
narrow band signals has increased further.
Your radio has a unique GME feature called Dynamic Volume Control that is able to automatically
compensate for these variations in received audio level. When activated, this feature automatically
adjusts the received audio level resulting in a constant audio output level to the speaker.
To enable Dynamic Volume Control
1. Press and hold the key to enter the Menu.
2. Press the key repeatedly until ‘DVCxx’ is displayed (where xx = ON or OF).
3. Press the key to enable the Dynamic Volume Control. DVCON will be displayed.
