Auto Audio Control

With AUTO AUDIO, the detector reports with reduced

audio alarms for any alerts that last longer than 5 seconds.

It holds the reduced audio level for any new alerts that

follow within 60 seconds of the alert that turned AUTO

AUDIO on.

Voice Alert On/Off Selection

• Press and hold Mute button repeatedly (for more than 2

seconds each time) to toggle between VOICE ON and

VOICE OFF.

• When the detector is set to VOICE ON, you'll be notified

by voice and visual alerts. VOICE OFF turns off all alert-

related voice messages but does not affect any other voice

messages.

• The detector won't provide the voice alert when the same

band signal is detected within one minute of the last signal.

seconds each time to toggle through four signal sensitivity

modes. They are: Highway1(H1) - Highway2(H2) - City1(C1)

with one beep, C1with two, C2 with three, and H1 is reset

with four beeps.

The detector detects all radar band (X, K, Ka) signals at

H1and C1, while it detects only K and Ka band signals at H2
