button on the remote control unit. The laser tool remains
in standby mode (the standby LED on the tool blinks
slowly).
When using the remote control unit, point the signal
transmission aperture on the remote control unit toward
the receiving window on the laser tool.
When switching the laser on, press and hold the on / off
button for 2 seconds.

If the pipe laser is moved, it can no longer be switched on
by the remote control unit. The message “Error” is shown
on the display of the pipe laser and the laser beam blinks
slowly.
Press the on / off button on the pipe laser and check that
the laser is set up correctly.
