Using Batteries

You can power your SCP-103 fro m two AA ba tteries (not su p­plied). We recommend RadioShack alkaline batteries. You
can also use rechargeable nickel-cadmium batteries. If you
use rechargeable batteries, you also need a battery charger
(not supplied, available at your local RadioShack store).

Cautions:

• Do not mix old and new batter ies, dif ferent type s of bat ­teries (standard, alkaline, and nickel-cadmium), or
rechargeable batteries of different capacities in the SCP-

103.

• Use only fresh batteries of the required size and type.

Follow these steps to install batteries.

1. Press down on the battery
compartment cover and
slide it in the direction of the
arrow, then lift it up on its
hinge to open it.

2. Install the batteries as indi­cated by the polarity sym­bols (+ and –) marked
inside.

3. Replace the cover.

If your SCP-103 locks up, remove one of the batte ries ,

Note:

then reinstall it.

14-1255.fm Page 7 Tuesday, July 27, 1999 10:47 AM

Replace th e batteries when the low battery icon fla shes on
the display, the sound distorts, or the volume weakens.

Warning:

Dispose of old bat ter ie s promp tly and p rop erly . Do

not burn or bury them.

Caution:

If you do not plan to use the SCP-103 for a month
or more, remove the batteries. Batteries can leak chemicals
that can destroy electronic parts.

Important:

At the end of a nickel-cadmium battery’s useful
life, it must be recycled or disposed of properly. Contact your
local, county, or state ha za rdou s w as te ma nagement authori­ties for information on recycling or disposal programs in your
area. Some options that might be available are: municipal
curbside collection, drop-off boxes at retailers such as your
local RadioShack store, recycling collection centers, and
mail-back programs.
