Portable 900 MHz Wireless Speaker System
Thank you for purchasing the RCA
Portable 900 MHz Wireless Speaker
System. Your system gives you high-quality
stereo sound in the 900 MHz band to
almost anywhere in or around your home.
Your Speaker System's three selectable
channels, PLL (Phase-Locked Loop)
circuitry and built-in antenna give you
precise tuning, so you can enjoy your
favorite music while you exercise or work
around your yard or house — up to 300
feet away from your stereo.
Your system has compander circuitry for
optimum dynamic range and noise
reduction, a 10-watt RMS amplifier in each
speaker, a 2-way speaker design with 5"
woofer and 1" dome tweeter. It has true
stereo operation with frequency ranges
from 50Hz to 20KHz (6dB bandwidth),
which will offer you the best sound. There
is no pilot tone spill over in this system,
and this improves your sound quality.
Also there is Automatic Level Control for
audio input to RF transmitter for optimum
FM deviation adjustment (plug and play,
no user adjustment is required)

Installing the Transmitter
Choosing a Location
In order to achieve the best performance,
position the transmitter as far as possible
from other electronic devices such as TVs,
receivers, or VCRs. Radio interference 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. Set up the
transmitter to send a wireless signal to the
speakers.
Connecting to AC Power
Connect the transmitter to AC power with
the supplied 12V, 250mA AC adapter. Plug
the supplied AC adapter's barrel plug into
the transmitter's
adapter into a standard AC outlet.
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
adapter meets these specifications.
Using an adapter that does not meet
these specifications will 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.

Connecting to an Audio Source
Mode Switch
You can connect the transmitter to your
audio source's left and right audio output
jacks or its headphone jack.
Cautions:
• Do not connect the transmitter to your
audio source's speaker output. Doing so
could damage the transmitter and the
audio source.
• If you connected the transmitter to an
audio source's headphone jack, set the
audio source's volume control to its
middle-position.
1. Connect one end of the supplied audio
patch cord to the transmitter's audio
jacks (white plug to
red plug to
R AUDIO IN).
L AUDIO IN and
2. If you are using the audio source's output
jacks, connect the white and red plugs
at the other end of the patch cord
directly to the audio source's
corresponding left (white) and right
(red) audio jacks.
For normal stereo use, set STEREO/MONO,
on the back of the transmitter, to
STEREO.
If you are using a monaural system, set
STEREO/MONO to MONO.
If you are using your audio source's stereo
headphone jack, connect the patch cord's
white and red plugs to the white and
red phono jacks on the phono side of

Installing Batteries
You can use 16 (8 for each speaker) D size
batteries (not supplied) to power the
speakers. Batteries are available at your local
RadioShack store or online at
www.radioshack.com.
Battery Notes:
• Use only fresh batteries of the required
size and recommended type.
• Do not mix old and new batteries,
different types of batteries (standard,
alkaline, or rechargeable), or
rechargeable batteries of different
capacities.
• If you do not plan to use the speakers
for a week or longer, remove the
batteries. Batteries can leak chemicals
that can destroy electronic parts.
1. Press the two tabs located on the back
of the speaker and open the battery
compartment cover.
2. Insert the batteries in the compartment
according to the polarity symbols (+
and –) marked inside the battery
compartment.

Connecting AC Power
1. Insert the supplied 12V, 1800mA AC
adapter’s barrel plug into the
jack located at the back of the speaker.
2. Plug the other end of the AC Adapter
into an AC wall outlet.
3. Route the adapter’s cord through the
strain relief slot on the back of the
speaker.
Repeat the above steps for the other speaker.

Mounting the Speakers
To mount a speaker on the wall, you need a
screw (not supplied) with a head that fits
into the keyhole slot on the back of the
speaker.
1. Select a location and drill a hole at the
location.
2. Thread a screw into the hole until the
screw’s head extends about 15mm from
the wall.
3. Align the keyhole on the speaker with
the screw head in the wall, then slide
the speaker downward to secure it.

Using Your System with Your PC
Follow these steps to use your speakers with your computer.
1. Connect the male end of the supplied cable adapter (
1
/8-inch stereo male to dual-1/8-inch
stereo female cable) to your computer’s audio output jack. Connect one of the cable ends
to your existing computer speaker plug and connect the other unused
cable end to the supplied Y-Adapter (
1
/8-inch stereo male to Dual-RCA female adapter).

2. Connect one end of the RCA adapter (Dual RCA-to-RCA) to the white and red phono
jacks on the phono side of the Y-adapter (
1

adapter).
3. Connect the RCA Adapter’s (Dual RCA-to-RCA) left (white) cable end to the transmitter’s
LAUDIOIN jack and the right (red) cable end to the transmitter’s R AUDIO IN jack.

Operation
Listening Safety
To protect your hearing, follow these
guidelines when you use the speaker system.
• Set the volume to the lowest setting
before you begin listening. After you
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.
• 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.
Using Your Speakers
Follow these steps to obtain maximum
listening performance:
1. Turn on your audio source.
See Transmitter AUTO ON/OFF below
for the transmitter operation.

Care
Keep the system dry; if it gets wet, wipe it
dry immediately. Use and store the system
only in normal temperature environments.
Handle the system carefully; do not drop it.
Keep the system away from dust and dirt,
and wipe it with a damp cloth occasionally
to keep it looking new.
Caution: You might permanently damage
your speakers by cleaning them with a
vacuum cleaner. Use a feather duster or a
soft cloth instead.

Troubleshooting
We do not expect you to have problems with your speaker system; however, if you do have
problems, try these troubleshooting tips.
Problem Solution
No sound. Be sure the speakers are turned on.
Replace the speakers’ batteries.
Be sure the AC adapter is plugged in and
has power.
Be sure all cables are securely connected.
Be sure the audio source is turned on and
turned to an active channel.
Adjust the speakers’ volume control.
Distorted audio. Be sure the speakers and transmitter are set
to the same channel.
If you connected the transmitter to an audio
source’s headphone jack, reduce the audio
source’s volume.
10
Change the position of the transmitter.
The speakers are placed beyond the
transmitter’s effective range (approximately
300 feet). Move the speakers closer to the
transmitter.
Other 900 MHz transmissions are being
picked up by the speaker’s receiver
(possibly from a 900 MHz cordless
telephone). Change the transmitter’s and
the speaker’s frequency channel.
The speaker’s batteries are low. Replace the
batteries.
