KCU 1051 CONTROL DISPLAY UNIT OPERATION
This section describes the KCU 1051 Control Display Unit controls
and display. The ALE database is preloaded as described in Section
XII.
KCU 1051 GENERAL OPERATING INFORMATION
KCU 1051 CONTROL DESCRIPTION
The controls on the KCU 1051 CDU are: PUSH/ON control, VOL
knob, SQUELCH knob, PUSH CHAR, CURSOR knob, VAR knob,
CLR key, ENT key, SCAN key, MSG key,
PUSH ON/VOL
This control (Figure 3-1) turns the system on and off and controls vol-
ume. Push the VOL knob to the in position to apply power to the unit
or pull the VOL knob to the out position to remove power from the
unit. Rotate the VOL knob to control the audio output level.
SQUELCH (SQL)
Squelch (Figure 3-2) is set by rotating the SQL knob counterclock-
wise until background noise is heard, and then turning it clockwise
until background noise is eliminated or just barely audible. When
using ALE, the squelch normally is turned off because ALE turns off
the audio until a call is received.
