User's Guide

The RCA brand Universal AC/DC Adapter allows you to power portable

devices requiring 300mA or less (AH30BR) or 500mA or less (AH50BR)

using a conventional AC electrical outlet.

Instructions:

1. Set the voltage selector switch to the proper setting for your device.

Refer to the device's user manual for the correct voltage requirement,

or determine the voltage by multiplying the number of AA, AAA, C, or

D batteries required by 1.5—for example, 4 batteries x 1.5 = 6 volts.

Note: Voltage setting may also be found next to the DC jack or on device

information plate.

2. Select the adapter plug tip that best fi ts device.

3. Before inserting the plug tip into the

AC adapter receptacle, you must fi rst

determine the correct polarity of your

device. Polarity is represented by the

following symbols.

Note: Polarity information may be found

next to the DC jack, user manual, or device

information plate. The adapter plug tips have a positive (+) symbol on one side

and a negative (-) symbol on the other side. The AC adapter receptacle says

"TIP" on one side.

4. If your device has positive polarity, align the word "Tip" on the AC

adapter receptacle with the (+) symbol on the adapter plug tip. See

7. If your device does not work, IMMEDIATELY unplug the AC adapter and

recheck the instructions carefully, particularly the voltage and polarity

settings.

CAUTION:

1. Never attempt to power a device for which the voltage or polarity is

unknown. Improper voltage or polarity settings may result in severe

damage to the device or AC Adapter.
