DISPLAY

Height alert warning of rotating laser *1
A flash and a buzzer sound signifies that the height alert function of rotating laser is operating.
Level sensor can detect the signal of height alert warning of the rotating laser.
(This function is not usable to the rotating laser which does not have the height alert and the function to output alarm signal.)

Rotating laser battery warning *2
A flash shows that the rotating laser power is low.
The level sensor can detect the rotating laser battery warning.
(This function is not usable to the rotating laser which does not have the function to output alarm signal.)

Battery remaining display
Indicates the battery remaining of level sensor as follows.

Note:The warning displays *1 and *2 are the functions that the level sensor detects alarm signal from the rotating laser. The level sensor can be canceled the alarm detection from the rotating laser.
To be canceled the detection; Press the power switch while pressing the buzzer sound switch when powering on.

AUTO-CUT OFF FUNCTION
