-By the direction indicators “move downward” d, “move
upward” for centre e on the display 2 on the front and back
of the detector.
-Optionally by the audio signal (see the following No. 6
“Audio Signal for Indication of the Laser Beam”
operation instruction).
Detector too low: If the laser beam runs through the upper
half of the reception area 6, then the direction indicator f on
the display. If the audio signal is switched on, a signal
sounds at high frequency.
Detector too high: If the laser beam runs through the lower
half of the reception area 6, then the direction indicator d on
the display. If the audio signal is switched on, a signal
sounds at low frequency.
Move the detector downward in the arrow direction.
Detector in centre position: When the laser beam runs
through the 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.
8. Working Advice
Marking
When the laser beam runs through the center of the
reception area 6, its height can be marked at the centre
mark 7 right and left on the detector.
When marking, take care to align the defector exactly
vertical ( for horizontal laser beam), or horizontal
(for vertical laser beam) by making use of the bubble vials 8
& 9 .
Rod Clamp Installation
The Detector can be used in hand or with an optional clamp
to install the detector to a measuring rod, pole or similar
object.
To install the clamp on the detector (See figure):
• Guide the clamp towards the detector by using the
alignment hole.
• Tighten the fixing screw.
(1) Alignment Points-help secure and align rod clamp.
(2) Captive Rod Clamp Screw-attaches to the back of
detector.
(3) Alignment Points-help secure and align rod clamp.
(4) Reversible Face-slanted face for round and oval rods;
flat face for rectangular and square rods.
(5) Clamping Screw Knob-secures clamp to rods by moving
the traveling jaw. Clockwise tightens; Counter clockwise
loosens.
