Battery Disposal 10.2
Some countries, states, and local
areas have regulations regarding
the disposal of rechargeable
batteries. Be sure that replaced
batteries are disposed of properly.
System Cleaning 10.3
Use only a good-quality glass
cleaner and a soft cloth to clean all
external optical components. A dry
cloth used on the laser’s/IR remote
control’s optical components or
displays could scratch or damage
these surfaces.
Blow off any loose debris before
cleaning any surfaces to prevent
scratching of optical surfaces.
Monthly, wipe off with a moist,
clean cloth any dust or dirt from
the laser’s outer surface, inside the
battery housing. Clean all corroded
battery contacts with a pencil
eraser or baking soda solution.
