PREPARATION
CONNECTING POWER
You can power your SCP-99 from:
• Internal batteries (not supplied)
• AC power (using an optional AC adapter)
• Your vehicle’s battery (using an optional DC
adapter)
Note: Connecting an adapter automatically discon-
nects internal batteries.
Using Batteries
The SCP-99 can use two AA batteries for power. For
the best performance and longest life, we recom-
mend alkaline batteries, such as RadioShack Cat.
No. 23-557.
You can also use rechargeable nickel-cadmium bat-
teries (Cat. No. 23-125). Use a battery charger (Cat.
No. 23-133) to recharge nickel-cadmium batteries.
Cautions:
• Use only fresh batteries of the required size and
recommended type.
