reception area 6 at the centre mark 7, the centre indicator e on the display.
When the audio signal is switched on, a continuous signal sounds.
6. Audio Signal for Indication of the Laser Beam
The position of the laser beam on the reception area 6 can be indicated via
an audio signal. After switching on the detector, the audio signal is always
set to high volume. The volume level can be decreased or switched off.
To change the volume level or switch off the audio signal, push the Audio
signal button 5 until the requested volume. level is indicated on the display.
At low volume level, the audio signal indicator c appears on the display
with no bar .
At high volume level, the audio signal indicator c appears on the display
with two bars . When the audio signal is set to off, the indicator goes
out. Independent of the audio signal setting, a short beep sounds at low
volume level every time when a button is pressed on the detector.
7.Indicators and lighting of the back display
The indicators and lighting of the back display are switched On/Off
simultaneously when the indicators and lighting of the front display are
switched On/Off.
