Operations
3.5.2 Setting the Volume
Setting the Volume on the Handset
The sound volume adjustment for the handset has 11 settings. Pressing
and releasing the VOL UP
key increases the volume by one level; pressing
and releasing the VOL DOWN
key reduces the volume by one level.
The number of segments in the VOL bar graph on the LCD display will
increase or decrease accordingly. If the VOL UP/DOWN keys are pressed
and held, the volume levels will automatically change every half-second.
Setting the Volume on the External Speaker
The volume knob on the External Speaker controls its sound volume.
Turning the knob clockwise increases the volume; turning it
counterclockwise reduces the volume. Turning the knob fully
counterclockwise until you hear a "click" switches off the speaker
completely.
The external speaker sounds alert tones, such as Distress calls, at maximum
volume regardless of the volume set with the knob, even when the knob is
set to the OFF position.
3.5.3 Setting the Squelch
The squelch adjustment enables you to "quiet" the receiver when no
signal is being received. The squelch adjustment for the handset has 11
settings. Pressing and releasing the SQ UP
key increases the squelch
by one level; pressing and releasing the SQ DOWN
key decreases it by
one level. The number of segments in the SQ bar graph on the LCD display
will increase or decrease accordingly. If the SQ UP/DOWN keys are pressed
and held, the squelch levels will automatically change every half-second.
3.5.4 Using the Function Key
Most of the keys on the handset control multiple operations. Pressing one
of these keys after pressing the FUNC key initiates the operation marked
on the label above that key. When the FUNC key is pressed, the FUNC
indicator is displayed on the LCD display. If no other key is pressed for 5
seconds, the Function operation is cancelled and the FUNC indicator
disappears.
