Uniden LRD 766 - Manual (Page 15)

MEMORY RETENTION FEATURE
The Memory Retention Feature retains the LRD 767/LRD 777’s
operational settings in memory for at least 2 days without power.
When you turn on the LRD 767/LRD 777, it will be in the same
mode as when you turned it off.
FULL WARNING
When the LRD 767/LRD 777 detects a radar, laser, VG-2 or safety
warning signal, it emits a distinct warning tone and the
corresponding visual messages will light. The blink rate of the LEDs
increases and the signal strength meter LEDs light successively as
the signal source comes closer.
AUDIO ALERT ONLY OPERATION
Press the audio button for Audio Alert Only operation.
When Audio Alert Only is selected, the visual alert and signal
strength meter are disabled. In this mode, the display panel will
dim. There are four levels for the display panel brightness control.
You can control the brightness by pressing the
audio button repeatedly.
Press the audio button again for the Full Alert (audio and
visual) Mode. Do not set the Volume control at minimum when in
Audio Alert Only because there will be no alert.
