Introduction
AR Wireless Stereo Speakers eliminate the hardest part of adding
speakers to almost any location in your home – running and hiding
hundreds of feet of speaker wire. Like FM radio, the AR Wireless Speaker
System’s 900MHz signal travels with ease through walls, floors, ceilings
and other obstacles, delivering high-quality stereo sound virtually
anywhere inside the house or out. With drift- and static-free reception
along with outstanding range – up to 300 feet* – the possibilities for
enjoying your AR Wireless Speaker System are nearly unlimited.
AR Wireless Stereo Speakers are compatible with most audio sources,
such as TVs, DVD players, VCRs, A/V receivers/amps, stereos,
computers, and portable devices (CD players, cassette players, MP3,
players, etc.).
This manual covers various connection options and detailed operating
instructions for making AR Wireless Speakers a valued part of your
lifestyle. If, after having reviewed the instructions, you have any
questions, please contact our Customer Service Department at
1-800-732-6866.

Important:
If you are using NiMH or NiCd batteries, the batteries will charge when the
headphones are powered with the AC power adapter. Do not power the headphones with the AC power adapter if you installed alkaline or other non-rechargeable batteries—this could cause the batteries to leak. Do not mix batteries with different chemistry types (for example, a zinc battery with an alkaline
battery). Do not mix new and used batteries. Do not leave batteries installed in
the product when not in use for long periods.

1. Turn ON your audio source (i.e., A/V receiver, TV, stereo, etc.) and play music
at a normal listening volume.
2.

Set the channel select switch (K) on the back of the transmitter to 1, 2 or 3.
The transmitter provides three different broadcasting frequencies. In the
event that you experience poor reception or interference, try choosing a
different frequency by moving the channel select switch to another position.

IV. Tuning the Speakers

A. Tuning indicator light (tuned)
B. Standby/Charging indicator

F. Left/mono/right switch

light (stdby/chrg)

C. Power/volume/scan control
1. Push the power/volume/scan controls (C) to turn each speaker ON. The
standby/charging indicators (B) will illuminate red while the speakers are
tuning to the transmitter. The “tuned” indicators (A) will illuminate blue,
indicating that the speakers are tuned to the transmitter, and you should
hear sound coming from the speakers.

Note: Once the speakers have tuned to the transmitter and the blue
“tuned” indicators are on, the red “standby/charging” indicators will turn off.

2. Adjust volume on each speaker as desired.
3.

For stereo operation, set the left/mono/right switch (F) to “left” on the
speaker located to the left of the listener, and set the other speaker to
“right” position. Set each speaker to “mono” for the best audio quality, if
you plan on using one speaker in a different room from the other.

4. The speaker will automatically retune if it loses the signal from the
transmitter. However, you can also push the power/volume/scan control to
retune the speaker at any time. While the speaker is tuning, the blue
“tuned” indicator will turn off and the red “standby/charging” light will be
lit. After locking onto the transmitter signal, the blue “tuned” indicator will
come back on and the red “standby/charging” indicator light will turn off.

Note: Interference in the form of static and/or distortion can sometimes
be heard. If this occurs, confirm the transmitter/speaker adjustments and
indicators. If the problem persists, refer to the Troubleshooting section
of this manual.

V. Turning the Speakers Off
1. Push and hold the power/volume/scan control (C) to turn each speaker OFF.
You will need to hold the control for about 1.5 seconds for the speaker to
turn off.
2. Confirm that the speaker is off by verifying that the red “standby/charging”
light and the blue “tuned” light are off.

Note: If rechargeable batteries are installed (NiMH or NiCd only) and the
speakers remain plugged in via the AC power adapters, the left
“standby/charging” indicator light will glow green, even after the
speakers have been turned off, indicating that the rechargeable batteries
are being charged.

VI. Recharging the Batteries
The speaker will automatically charge the rechargeable batteries when the
batteries are installed and the speaker is plugged in with the AC power adapter.
The “standby/charging” indicator (B) will light up green to confirm that the
batteries are being charged.

Warning: The AW871 built-in charger will charge rechargeable NiMH or
NiCd batteries only. DO NOT attempt to charge any other batteries except
those specified above.
Warning: If alkaline or other non-rechargeable batteries are installed, DO
NOT plug in the speakers using the AC power adapters. This can cause the
batteries to leak and damage the speakers. Only use rechargeable batteries if
you intend to keep the speakers plugged in.

VII. More Helpful Information
i. About Fixed-Level Audio Outputs:

A fixed-level, or line-level audio output is considered ideal since it provides
an audio signal unchanged by adjustments to the audio source (stereo, etc.)
volume control.

Hint: Fixed-level audio outputs from stereo receivers/amps will typically be
designated as Tape, Tape 1, and Tape 2 outputs, or VCR audio output
connections.
These outputs are frequently marked on A/V equipment as ‘TAPE OUTPUT,’
‘TAPE OUT,’ ‘TAPE REC, or ‘TAPE RECORD or REC OUT.’
Please note: Jacks labeled PHONO, CD, LD, DVD or tape or VCR playback
(PB) are INPUTS and will not work with the transmitter.

Fixed-level outputs from TVs are usually marked as ‘Constant,’ ‘Fixed,’ or
‘Select.’ If they are not marked as such, they are probably variable outputs (see
“About Variable-Level Audio Outputs” below). Outputs from VCRs are almost
always fixed.

Hint: When connecting to the audio outputs of a VCR, remember that the
VCR must be playing a tape or showing a TV channel for sound to be
produced.

Hint: If your VCR (or other audio source with RCA jacks) only has a single
audio output, you will need another RCA “Y” cable. It differs from the “Y”
Cable Adapter included with these speakers. It will have a single male RCA
plug and 2 female RCA jacks. Connect the dual RCA plugs from the
included “Y” cable adapter to the 2 female RCA jacks on the second “Y”
cable, and then connect the single male RCA plug of the second “Y” cable
to the single audio output of the VCR.

ii. About Variable-Level Audio Outputs:

A variable-level output, such as a headphone jack or certain RCA-type outputs,
provides an audio signal that changes with the volume level set on the
audio source (stereo, etc.). As the volume of the audio source is adjusted up
and down, so is the audio signal strength sent to the transmitter. This can
affect the quality of sound generated by the speakers, and may require an
adjustment of the volume level of the audio source to produce a signal strong
enough for the transmitter.

Hint: On most bookshelf-type or compact stereo systems, inserting a
headphone plug into the headphone jack results in automatic cutoff of the
regular, or hard-wired speakers.

Hint: Most TVs, regardless of age or price, have variable outputs. If you are
unsure which of your TV audio outputs is fixed, refer to the TV instruction
manual. Some TVs have outputs that can switch between variable and
fixed. When given a choice, fixed is always recommended.

VIII. Troubleshooting
The following troubleshooting guide takes you through some of the more
common problems associated with the installation and/or operation of a wireless
system. If the problem persists, please call 1-800-732-6866 and a knowledgeable
customer service representative will assist you.

Issue:

Cause and solution:

No
sound

• Check that the transmitter AC power adapter is fully inserted into the wall
outlet and the power cord from the AC adapter is firmly connected to the
transmitter power input jack.
• Confirm that the speakers are turned ON and tuned to the transmitter –
the blue “tuned” indicator light should be glowing steadily.
• Confirm that the speaker AC power adapters are fully inserted into the wall
outlet and the power cord from each AC power adapter is firmly
connected to the speaker power input jack.
or
• Check that the C-cell batteries are fresh and inserted with correct polarity
(+, –).
• Check that the audio source component (stereo, TV, etc.) is turned on and
transmitting sound as it normally should.
• Check that the speaker volume is turned up.
• If you are using a Tape 2 Monitor output from your receiver/amp as the
audio output, check that you have pressed the Tape Monitor/Tape 2
button on the front of the receiver. This will turn on the Tape 2 outputs,
which may not have been active.

When using battery power, make sure the batteries are fresh and replace
if necessary.
Check that the speaker “tuned” indicator light is illuminated blue.
Change the position of the channel select switch (1, 2 or 3) to change the
operating frequency. The speaker will detect the loss of signal and
retune automatically. However, you can also press the power/volume/scan
control once to make the speaker retune.
Change the location of the transmitter. Place it as high and away from
obstructions as possible. Avoid placing the transmitter directly on top of or
behind a TV.
Move the transmitter and speakers closer together. Sending the signal
through certain materials, such as glass, tile, and metal, can decrease the
effective transmitting distance of the system.
