900 MHz Wireless Stereo Headphones
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.
If you cannot eliminate the interference, the
FCC requires that you stop using your headphones.
Warning: Changes or modifications to this
unit not expressly approved by the party responsible for compliance could void the user’s authority to operate the unit.
Notes:
THE FCC WANTS YOU TO
KNOW
• This equipment has been tested and
found to comply with the limits for a
Class B digital device, pursuant to Part
15 of the FCC Rules. These limits are
designed to provide reasonable protection against harmful interference in a
residential installation. This equipment
generates, uses and can radiate radio
frequency energy and, if not installed
and used in accordance with the instructions, may cause harmful interference to
radio communications.
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.
• Your headphones are subject to interference from other devices, such as cordless phones, wireless speakers, and
other wireless headphones that operate
on the same frequencies. If you experience interference, try moving the headphones away from the other device.
Power/Transmitter Indicator — lights
green when the AC adapter is correctly
plugged in and turns amber when the transmitter is on.
Charging Indicator — lights red when the
battery is charging.
Try to eliminate the interference by:
• moving your headphones’ transmitter
away from the receiver
PREPARATION
Choosing a Location
• connecting your headphones’ transmitter to an outlet that is on a different electrical circuit from the receiver
Many factors affect the range of your system.
To achieve the best performance:
• contacting your local RadioShack store
for help
• Position the transmitter as far as possible from other electronic devices such
as TVs, receivers, or VCRs. Radio inter© 2000 RadioShack Corporation. All Rights Reserved.

ference from these devices could affect
your system’s performance.
you can alternately charge one and use the
other.
• Position the transmitter away from large
metal objects, as these could block your
transmitter’s signals.
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.
• Try several locations for the transmitter.
Select the location that provides the best
performance.
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.
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.
Charging
Portal
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 DC 12V jack. The supplied adapter
meets these specifications. Using an
adapter that does not meet these specifications could damage the transmitter or
the adapter.
Battery
Pack
POWER
To charge the
battery pack,
plug it into the
transmitter’s
charging portal.
The battery pack
automatically begins charging
and the
CHARGE indicator lights.
When charging is complete, unplug the battery pack. The indicator turns off.
Note: You can charge the battery pack with
the transmitter set to on or off.
• 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.
Installing a Battery Pack
1. Remove the
battery compartment
cover on the
left earpiece
by pressing
the sides of
the cover
and lifting it
off.
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

tabs inside the compartment.
begin listening, adjust the volume to a
comfortable level.
• Do not listen at extremely high volume
levels. Extended high-volume listening
can lead to permanent hearing loss.
3. Replace the cover.
Warning: Dispose of old batteries promptly
and properly. Do not burn or bury them.
• Once you set the volume, do not increase
it. Over time, your ears adapt to the volume level, so a volume level that does
not cause discomfort might still damage
your hearing.
Caution: When you replace the battery, use a
RadioShack replacement battery pack.
Note: When the headphones stop operating
properly, replace or recharge the battery pack.
Using Your Headphones
Connecting to an Audio Source
You can use multiple sets of headphones with
each transmitter. We do not recommend using
multiple transmitters in the same area.
To connect the transmitter to your audio
source, connect one end of the supplied stereo audio cable to the transmitter’s R/AUDIO IN
(red plug) and L/AUDIO IN (white plug) jacks.
Then plug the other ends into the audio
source's audio output or headphone jacks.
1. Set the headphones’ channel (1 – 3) to
the same channel as the transmitter.
2. Turn on the transmitter and the audio
source.
