6. Operating Instructions
IMPORTANT: It is the responsibility of the user to verify the
calibration of the instrument before each use.
Battery Installation
Open the cover on the back of the unit in
accordance with markings on the cover and insert
three AAA batteries (included in 40-0912 only).
Place cover back onto unit.
Note: Used (discharged) batteries are hazardous
waste and should be disposed of properly.
The unit must be locked/turned off before returning the laser to its
case. Locking the unit must be done when the unit is in its upright
position. It is done to hold the internal components in place to avoid
damage to the internal mechanism during transport. The
knob must be unlocked/turned on prior to each use and
locked/turned off after each use of the laser.
Tripod Set-up
Open up the tripod and position it firmly on a surface that is even
and as near level as possible. For uneven surfaces and inclines,
compensate by adjusting the telescoping legs of the tripod. Tightly
screw the unit and tripod together.
Tripod working range from 17" to 47".
The laser can be used either with the tripod or independently.
