3-14 Operations

3.5.2Setting 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.

3.5.3Setting 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.

3.5.4Using 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.
