PREPARATION
You can power your SCP-83 from any of these power
sources:
• Internal battery power
• Standard AC power (using an AC adapter)
• Vehicle battery power (using a DC adapter)
USING INTERNAL BATTERY
POWER
You can power the SCP-83 from two AA batteries
(not supplied). For the best performance, we recom-
mend alkaline batteries, such as RadioShack Cat.
No. 23-557. Follow these steps to install batteries.

1. Press down on the battery compartment cover
and slide it off in the direction of the arrow.
2. Install the batteries as indicated by the polarity
symbols (+ and –) marked next to the compart-
ment, with the back battery over the ribbon.
Cautions:
• Use only fresh batteries of the required size
and type. Never mix fresh and old batteries or
different battery types.
• Always dispose of old batteries promptly and
properly.
3. Replace the cover.
Notes:
• If the sound gets distorted or weak, replace the
batteries.
• If you do not plan to use the SCP-83 for a week
or more, or if you plan to power it using only an
AC or DC adapter, remove the batteries. Batter-
ies can leak chemicals that corrode or damage
electronic circuits.

USING AC POWER
You can power the SCP-83 from AC power using an
optional AC adapter, such as RadioShack Cat. No.
273-1654.
Cautions:
• The recommended AC adapter supplies 3 volts
and delivers at least 300 milliamps. Its center tip
is set to negative, and its plug correctly fits the
SCP-83’s DC 3V jack. Using an adapter that
does not meet these specifications could dam-
age the SCP-83 or the adapter.
• Be sure the adapter is connected to the SCP-83
before you connect it to the AC outlet and that
you disconnect the adapter from the AC outlet
before you disconnect it from the SCP-83. Oth-
erwise, the unconnected plug might touch some
metal and damage the adapter.

Follow these steps to power the SCP-83 from a stan-
dard AC outlet.
1. Set the adapter’s voltage switch to 3V.
2. Insert the adapter’s 3.4 mm outer diameter/1.3
mm inner diameter barrel plug into the adapter’s
cord so it reads –TIP.
3. Insert the adapter’s barrel plug into the SCP-83’s
DC 3V jack.
4. Plug the adapter into a standard AC outlet.
Connecting an AC adapter automatically disconnects
internal battery power.

USING VEHICLE BATTERY
POWER
You can power the SCP-83 from a vehicle’s battery
using an optional DC adapter, such as RadioShack
Cat. No. 270-1560.
Cautions:
• The recommended DC adapter supplies 3 volts
and delivers at least 300 milliamps. Its center tip
is set to negative, and its plug correctly fits the
SCP-83’s DC 3V jack. Using an adapter that
does not meet these specifications could dam-
age the SCP-83 or the adapter.
• Be sure the adapter is connected to the SCP-83
before you connect it to the cigarette-lighter
socket and that you disconnect the adapter from
the cigarette-lighter socket before you discon-
nect it from the SCP-83. Otherwise, the uncon-
nected plug might touch some metal in the
vehicle and damage the adapter.
