Operation; Power On; Volume Control - Uniden LRD747 Reference Manual

OPERATION

You are now ready to enjoy the convenience and security of your
LRD 747/LRD 757. Please read this section of the Reference Guide
carefully to familiarize yourself with the basic operation of this
unit.

POWER ON

Turn the volume control to switch on the power. When you
power up the LRD 747/LRD 757, it performs a self-test of all its
circuits. This test takes about 5 seconds, during which you will
hear the different alarm tones and see all the LEDs. First, you will
hear the X-band alarm for 2 seconds while the X-band indicator
lights. The test also checks the signal meter LEDs. It is best to
adjust the audible alarm during the self-test. Next you'll hear the
K-band alarm while the K-band indicator and City LED lights,
Ka-SuperWideband alarm while the Ka-Band indicator and mute
LED lights. The laser alarm and the SWS alarm will each alarm
for 1 second, while the City and Mute LED light. The VG2 alarm
will alarm for 2 seconds while the City and Mute LED light.(The
power LED remains on until you turn off the unit.) When turned
on the LRD 747/LRD 757 always returns to its last setting.
After the LRD 747/LRD 757 confirms proper operation,
the alert tones and all LEDs, except the green Power LED, turn
off. If the Power LED does not light, check the cigarette lighter
socket connection. If the unit turns on and off intermittently, or
the alert tone sounds too often for no reason, check the power
cord connection at both ends to be sure it is not loose.

VOLUME CONTROL

Adjust the volume control to a comfortable alarm tone level for
your vehicle. The volume level does not have any effect on the
unit's sensitivity. It is best to adjust the audible alarm during the
self-test.
