Tilt alarm
▪ Once the instrument has been levelled off
the tilt alarm can be enabled by pressing
the tilt alarm button on the instrument.
The tilt alarm indicator light will flash
continuously whilst active.
▪ If the instrument is disturbed while the
alarm is active the instrument will stop
rotating and will need to be powered off
and on again to reset its level position.
OPERATION
Powering on
▪ Press the power button once and the
instrument will power on and begin
automatically self-levelling. When this
levelling process is complete, the penta
prism inside the lighthouse will start rotating.
▪ If the instrument is outside the self levelling
range the instrument will not level causing
the laser beam to flash continuously. If this
occurs, reposition the instrument onto a level
surface until the instrument can level off.
Powering off
▪ Press the power button once and the
instrument will power off.
