3. Before you install alkaline or any other non-
rechargeable batteries, use a pointed object
such as a ballpoint pen to set 
ALKALINE   JACK
 NI-CD 
inside the compartment to 
ALKALINE
.
Warning:
 Set 
ALKALINE  JACK  NI-CD
 to 
NI-CD
for use only with nickel cadmium (Ni-Cd) or nickel
metal hydride (Ni-MH) rechargeable batteries. 
Never
attempt to recharge non-rechargeable batteries.
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 recharge-
able), or rechargeable batteries of different
capacities.
5. Replace the cover, inserting the lower tabs first.
