Resetting the  
Headphones  
If you ever want to return the  
headphones to their factory presets,  
simply reset the headphones by  
triggering the reset button on the  
right headphone with a paper clip.  
Important Note About Audio Outputs  
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.  
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.

uS I n G Yo u r He a d p H o n e S  
• 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  
tr o u B l e S H o o t I n G  
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  
The headphones can be reset as well. If you experience persistent problems with the  
headphones, see page 9 for reset instructions.  
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.

tr o u B l e S H o o t I n G  
Confirm that the headphones are turned on (the LED is blue) and tuned to the  
transmitter. If the LED on the right headphone is flashing blue, the headphones  
are not tuned to the transmitter. Press the link key on the headphones and on the  
transmitter’s back panel to tune the headphones.  
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.  
LEDs fail 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  
Check the LED on the right headphone. If it’s blinking, you’ve lost the transmitter’s  
signal. Move closer to the transmitter. If you don’t see the LED, the headphones’  
rechargeable battery needs to be recharged. Use the AC adapter to recharge the  
headphones.
