the OFF position. The pendulum unit is locked when the tool is
switched off.
Never leave the measuring tool unattended
when switched on, and ensure the measur-

If the maximum permitted operating temperature of 113 °F (45
°C) is exceeded, the tool shuts down to protect the laser di-
ode. Once it has cooled down, the measuring tool is operational
again and can be switched back on.
Automatic shut-off
The measuring tool automatically switches itself off after 60 min

Position the measuring tool on a level, firm support or attach it

After switching on, the automatic levelling function automati-
