Adjusting the Transmitter

1. Turn on your audio source (for example, A/V receiver, MP3 player, stereo, etc.) and

play music at a normal listening volume.

2. Set the channel select switch on the back of the

transmitter to one of the transmitter's three broadcast

When the transmitter is receiving an audio signal and is

ready, the SIGNAL indicator turns solid green.

Note

If the SIGNAL indicator on the transmitter does not turn on, please check the

following:

- Confirm the transmitter AC power adapter is securely connected.

- Confirm the cable from the transmitter is securely connected to the audio source

output (MP3 player, A/V receiver, etc.).

- Confirm the audio source is playing audio and is turned up.

Tuning the Speaker

1. Press the Music On/Off button on the bottom

of the speaker to turn it on. The indicator

light on the front of the speaker blinks while

the speaker is tuning to the transmitter.

The indicator light turns solid blue when

the speaker is tuned to the transmitter—you

should hear sound coming from the speaker

now.

Note: If the speaker is on a switched outlet, make sure the outlet is on.

Note: If the speaker is not tuned or if the transmitter is not connected properly, the

indicator light will continue blinking. If this occurs, please see the troubleshooting

section of this manual.

2. Adjust the volume on the speaker as desired.

3. Set up the speaker for mono or stereo operation using the switch on the bottom of

the AW850 speaker.

a) Monaural operation: The monaural mode (mono) is recommended when using a

single AW850 by itself. For monaural operation, set the L/M/R switch to "M" on

the speaker.

b) Stereo operation: You need an additional AW850 speaker for the stereo option.

Set the L/M/R switch to "L" on the speaker located to the left from the listener,

and set the other speaker to the "R" position.

Notes:

A single AW850 transmitter can send its signal to more than two speakers. All you need

to do is tune the speakers to the single transmitter.

The speaker automatically retunes if it loses the transmitter's signal. You can also press

the Auto Scan button on the bottom of the speaker to retune the speaker at any time.

The transmitter turns off automatically if there is no audio signal present for a prolonged

period.

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.

Turning the Speaker Off

1. Press Music On/Off button on the bottom of the speaker to turn the speaker off.

2. Confirm that the speaker is off by verifying that the indicator light on the speaker's

front panel is no longer illuminated.

Turning the Lamp On and Off

To turn the lamp on: Put the Light On/Off switch on the bottom of the speaker in the

on position. If the lamp is on a switched outlet, make sure the outlet is on.

To turn the lamp off: Put the Light On/Off switch on the bottom of the speaker in the

off position.

More Helpful Information

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 volume control.

Hint: Fixed-level audio outputs from stereo receivers/amps will typically be

designated as Tape (or Record) outputs or DVR/DVD-R audio output connections.

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 DVD players are almost always fixed.

Hint: When connecting to the audio outputs of a DVD player, remember that the DVD

player must be showing a TV channel for sound to be produced.

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.

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

speaker, 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.

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 toll-free at 1-800-732-6866 or visit www.araccessories.com.

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 speaker is turned on and tuned to the transmitter—

the indicator light on the front of the speaker should be solid blue (not blinking).

• If the speaker is on a switched outlet, make sure the outlet is on.

• Check that the audio source component (stereo, MP3 player, etc.) is turned on and

transmitting sound as it normally should.

• Make sure the volume on your audio source is turned up.

• 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.

No sound/

• Check that the speaker's indicator light is solid blue (not blinking).

distortion/

• Change the position of the channel select switch (1, 2 or 3) to change the operating

static

frequency. Then press the Auto Scan button on the bottom of the speaker 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 closer to the speaker. Sending the signal through certain

materials, such as glass, tile, and metal, can decrease the effective transmitting

distance of the system.

Bulb doesn't

• Make sure the light on/off switch on the bottom of the lantern/speaker is switched

on.

• Make sure the bulb hasn't burned out. Try a new bulb in the lantern/speaker.

• If the above solutions don't work, turn off power to the outlet at the circuit box and

make sure the lantern/speaker is wired correctly.

Circuit breaker

• The lantern/speaker is probably wired incorrectly. Turn off power to the outlet at the

trips when you
