OWNER’S MANUAL — Please read before using this equipment.

Your RadioShack Rechargeable 900 MHz
Wireless Stereo Headphones use the 900
MHz band to deliver high-quality stereo
sound to almost anywhere in or around your
home. Your headphones’ three selectable
channels, PLL (Phase-Locked Loop) circuitry
and built-in antenna give you precise tuning,
so you can enjoy your favorite sounds with­out disturbing others while you exercise or
work around your yard or house — up to 150
feet away from your stereo.

THE FCC WANTS YOU TO
KNOW

Your headphones might cause TV or radio
interference even when they are operating
properly. To determine whether your head­phones are causing the interference, turn off
the headphones. If the interference goes
away, your headphones are causing the in­terference.

Try to eliminate the interference by:

• moving your headphones’ transmitter
away from the receiver

• connecting your headphones’ transmit­ter to an outlet that is on a different elec­trical circuit from the receiver

• contacting your local RadioShack store
for help

If you cannot eliminate the interference, the
FCC requires that you stop using your head­phones.

ference from these devices could affect
your system’s performance.

• Position the transmitter away from large
metal objects, as these could block your
transmitter’s signals.

• Try several locations for the transmitter.
Select the location that provides the best
performance.

Your system’s overall performance depends
on your home’s construction method, the oth­er devices near the system, and other radio
frequency sources in your home (such as
cordless telephones).

Using AC Power

Use the supplied 12V, 250mA AC adapter to
connect the transmitter to AC power.

Cautions:

• You must use a Class 2 power source
that supplies 12 volts DC and delivers at
least 250mA. Its center tip must be set to
positive and its plug must fit the transmit­ter's

jack. The supplied adapter

DC 12V

meets these specifications. Using an
adapter that does not meet these specifi­cations could damage the transmitter or
the adapter.

• Always connect the AC adapter to the
transmitter before you connect it to AC
power. When you finish, disconnect the
adapter from AC power before you dis­connect it from the transmitter.

Plug the supplied AC adapter’s barrel plug
into the transmitter’s

DC 12V

jack, then plug

the adapter into a standard AC outlet.

Charging the Rechargeable Battery
Packs

To power the headphones, use the supplied
nickel-metal-hydride rechargeable battery
packs. There are two batteries supplied, so

you can alternately charge one and use the
other.

Your transmitter has a built-in charger to
charge the rechargeable battery pack. When
the headphones are not in use, the battery
pack can be continuously charged over sever­al days.

Before using your headphones for the first
time, you must charge the battery pack for at
least 24 hours. If the headphones’ range de­creases, you do not hear sound from the au­dio source, or the headphones’ POWER
indicator is blinking, recharge the batteries. It
takes 12 to 14 hours to completely recharge
the batteries.

To charge the
battery pack,
