Squelch Key

H/L Power Key

Squelch Key - This key breaks the squelch

(unmutes the audio) when pressed and held. It

is also sed to set the squelch threshold (the

level at which only strong signals can be

received). The squelch threshold is set by

pressing and holding the squelch key while

using the UP/DOWN keys to adjust the

squelch level from 0 to 9. At level 0, all signals

can be heard, while at level 9, only the stron-

gest signals can be heard. Adjusting the squelch

level eliminates weak, unwanted signals, as

explained on page 17.

H/L (High/Low) Power Key - This key toggles

the transmitter power level from High (5 watts)

to Low (1 watt) when pressed and released. It

also locks the keypad when pressed and held

for more than one second.. The Power key,

PTT key, backlighting key and the Squelch key

still function in the Lock mode. Locking the

keypad prevents inadvertent changing of

channel settings and feature modes.
