3. If you are installing alkaline batteries, use a
pointed object such as a pencil to set ALKALINE
JACK NI-CD inside the compartment to
ALKALINE . Or, if you are installing nickel-cadmium
batteries, set it to NI-CD .
Warning: Never set ALKALINE JACK NI-CD
to NI-CD if you are installing non-rechargeable bat-
teries. 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 dif-
ferent capacities.
5. Replace the cover.
