AUTO-CUT OFF FUNCTION
The power will be turned off automatically after detecting no laser beam for more than approx. 30
minutes. (To turn on the level sensor, press the power switch again.)
*1, 2 For more information about the warning displays of above *1 and *2, refer to instruc-
tion manual of each rotating laser.
REPLACING BATTERY
1
Keep pushing the battery cover in 1 direction
,
and then try to
slide the cover in 2 direction.The cover does not move but it
will be open.
2
Take out the battery and place a new one into the battery box.
3
Press the lid down and click to close.
• Replace all 2 batteries with new ones at the same time. Do not mix used and new batteries, and do not
mix different types of batteries together.
• Use alkaline dry cells. (Dry cells for movement confirmation are packed in shipment.)
Nickel hydrogen dry cells and nickel cadmium dry cells can be used too, but the operating time is dif-
ferent from the time of alkaline dry cells.
• Generally, performances of dry cell deteriorate temporarily in low temperature, but recover in normal
temperature.

*1
(Except for LS-80G)
A flash and a buzzer sound signifies
that the height alert function of rotating
laser is operating.
