Screen options cont’d
“fast mode” to change frequencies quickly. Release the button to stop
the fast change. Some practice is required to stop the frequency scan
near the desired frequency. The final frequency can be selected by
quickly tapping the Up or Down button to get to the frequency
desired. Once the final frequency is selected, press the Set button once
to save the frequency. To return to Group/Channel mode, press both
the Set and the Up buttons at the same time.
To change the Squelch Level :
(Other than the factory setting), press and hold the UP button for 3
seconds. The Squelch screen can now be seen.
CAUTION!!! Setting the squelch level to 0 opens (disables) the
Squelch which will allow LOUD noise to be heard on the audio
system!! Turn the audio volume down before proceeding!
Lower values of squelch (1-5) enable weaker signals to be heard that may
include weak interference. Higher values of squelch (5-9) prevent weak
interference from being heard but also shorten the operating range
(distance) and may increase the risk of noise-ups or drop-outs.
Once the desired squelch value is selected, press the SET button to
save the setting.
Note: If any display item is flashing, the Power Off button will not
operate. Press Set to save all items before power off.
