2.Press the power button on the right headphone to
turn the headphones on.
3.Switch on the audio source (TV, DVD, CD player,
etc.) to which the transmitter is connected. If your
audio source is a DVD or CD player, start a disc.
4.The headphones and transmitter should automatically lock onto each other for
wireless transmission.
If they don’t tune automatically, or if you experience interference in the
transmission, press the ch select button on the top of the transmitter until you
find the clearest channel. The headphones beep when they lock onto a new
channel. If you don’t hear a beep, the current channe might be in use by other
2.4GHz devices (such as a wireless router). Push the ch select button again to try
another channel. There are 8 channel frequencies available.
5.Adjust the volume using the volume up and down buttons on the left earphone.
Turning the Headphones Off
To turn the headphones off: Press and hold the power button on the headphones
for 1 second. Don't forget to switch off the transmitter too!
If you’re using the LINE IN input...
If possible, use a fixed-level (or line-level) audio output from your audio source.
This kind of output provides a consistent level of audio that doesn’t change when
you adjust the source’s volume control.
Fixed-level audio outputs from stereo receivers/amps are typically designated as
tape or VCR audio output connections, sometimes marked on the component as
‘TAPE OUTPUT,’ ‘TAPE OUT,’ ‘TAPE REC, or ‘TAPE RECORD or REC OUT.’
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.
Important: Jacks labeled CD, DVD/DVR, PHONO, or tape playback (PB) are INPUTS
and will not work with the transmitter.
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 headphones, and may require an adjustment of the volume level
of the audio source to produce a signal strong enough for the transmitter.
Hints:
• 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.
• 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.
Listen safely!
Enjoy your headphones at a safe volume. Avoid or limit the amount of time you
listen at higher volumes—permanent hearing loss may occur if the headphone is
used at too high a volume. If you experience a ringing in your ears, or your own
voice and other sounds seem muffled, stop using the headphones and consult a
hearing professional.
Battery life
Due to the chemistry of the headphones’ rechargeable battery, required charging
time may increase while the actual capacity of the battery may decrease. If you
have any questions regarding the replacement of the built-in battery, please call
toll-free 1-800-732-6866 or visit www.araccessories.com.
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 1-800-732-6866 or visit
www.araccessories.com.
Issue:
Cause and solution:
No sound
• Make sure the transmitter’s 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.
• Check that the audio source component (DVD player, TV, etc.) is turned on and
transmitting sound as it normally should. If you’re using a PC or DVD player,
make sure you’ve selected the correct audio output and that the sound is not
muted.
• Confirm that the headphones are turned on (the LED is blue) and tuned to the
transmitter. If the LED is not blue, press the ch select key on the transmitter to
try a different channel. If this doesn’t work, press and hold the mute/link key on
the headphone and the ch select/link key on the transmitter simultaneously for 3
seconds.
• Make sure the headphones are charged—the LED on the right headphone should
be blue.
• Check that the headphone volume is turned up.
• If you’re using a variable output audio source (like a headphone jack or variable
output on a TV set), make sure the source component’s volume is set high
enough for the transmitter to detect.
• 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.
Interrupted
sound
• Move closer to the transmitter with the headphones on. Sending the signal
through certain materials, such as glass, tile, and metal, can decrease the effective
transmitting distance of the system.
• Try a different channel from the transmitter: press the ch select key on the
transmitter’s top panel.
LED fails to
light up
• Make sure the headphones are charged and that the transmitter is properly
connected to the audio source. Then, move the headphones close to the
transmitter and press the headphone power button again.
Headphones
shut off
automatically
• Move closer to the transmitter.
Headphones
start beeping
• If you’re trying to find a different channel on the transmitter, the headphones
beep when they lock onto a new channel.
• The headphones’ rechargeable battery needs to be recharged. Use the charging
cable on the transmitter to recharge the headphones.
• The headphones beep every few seconds when the batteries are running low. Use
the charging cable on the transmitter to recharge the headphones.
