THEIS TCL POCKET Instructions De Service page 20

Align the centre line of the LVH100 parallel to the laser line and
then move the detector slowly in the direction of the laser line
until one of the arrow symbols lights up.
Now move the detector toward the centre until only the centre
indicator lights up blue.
If the horn is switched on, a continuous tone is issued when the
centre is displayed. When the arrows are displayed, a tone
differently pulsating indicates in which direction the detector
must be moved to reach the centre.
Arrow and centre indicators are placed on the front of the
detector. On the back and the outer sides of LVH100 a centre
notch is shown.
If no laser beam hits the detector field (sensor window) for
approximately 10 minutes, the detector switches off. A short
sound is emitted if the horn is switched on.

When unused for long of the device, the batteries should be
removed to avoid discharge and corrosion deposits.
