Laser batteries
The laser is powered using two high energy AA size alkali-manganese 1.5 V batteries (use only
Duracell Industrial ID 1500 or Energizer E91). These provide a typical operating duration of
120 hours.
CAUTION
As the battery becomes depleted, the colour of the 'laser active' indicator LED changes
from green (full) to yellow (half full) to red (empty). When this occurs, the batteries
should be replaced.
If the laser is not in use for extended periods of time, a month or more, the batteries
should be removed from the unit.
Replacing laser batteries
Batteries must be changed only outside the explosive area! Note that only alkali-man-
ganese batteries can be used in explosive atmospheres.
The batteries are replaced by undoing the quarter-turn screw (1) on the battery compartment
cover (2) by rotating it by at least 90° (1/4 turn). With the screw loosened, lift the cover, and
then use the red strap (3) to remove the batteries. Replace both batteries at the same time.
CAUTION
Under no circumstances may the two smaller housing hex head screws be removed, as
that would void all warranty coverage.
Used batteries should be disposed of in an environmentally-sound manner!
