3. Before you install alkaline or any other non-
rechargeable batteries, use a pointed object such
as a ballpoint pen to set
inside the compartment to
CD
Warning: Set
for use only with nickel cadmium (Ni-Cd) or nickel
metal hydride (Ni-MH) rechargeable batteries.
Never attempt to recharge non-rechargeable batter-
ies. Non-rechargeable batteries can get hot or
explode if you try to recharge them.
4. Install two batteries in the compartment and two in
the cover as indicated by the polarity symbols (+
and –) marked inside those locations.
Cautions:
• Use only fresh batteries of the required size and
recommended type.
• Always remove old or weak batteries. Batteries
can leak chemicals that destroy electronic cir-
cuits.
• Do not mix old and new batteries, different types
of batteries (standard, alkaline, or rechargeable),
or rechargeable batteries of different capacities.
