Universal AC/DC Adapter
AH3WH/AH5WH User’s Guide
The RCA brand Universal AC/DC Adapter
allows you to power portable devices
requiring 300mA or less (AH3WH)
or 500mA or less (AH5WH) 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 1.5m
= 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 fits device.
3. Before inserting the plug tip into
the AC adapter receptacle, you
must first 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
diagram below.
If your device has negative polarity,
align the word “Tip” on the AC
adapter receptacle with the (-)
symbol on the adapter plug tip. See
