• 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.

No sound
• Make sure the transmitter's 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 (stereo, 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.
