BATTERY INSTALLATION  
PLUGGING IN & TURNING ON  
Open the battery compartment by sliding the compartment cover in the  
direction of the arrow printed on the cover. Install two AAA alkaline batteries  
in accordance with the polarity symbol ( + ) diagram printed on the base of  
the compartment.  
1. Locate a 120 volt AC outlet no more than approximately five feet from the  
sound system and plug the Transformer on the end of the AC/DC Power  
Cord into the outlet.  
(This Transformer converts standard 120 volt AC household current into  
12 volt DC current).  
Replace the battery compartment cover.  
2. Plug the other end of the AC/DC Power Cord into the AC/DC input jack  
on the underside of the Transmitter base.  
3. Plug the Audio Cord leading from the underside of the Transmitter base  
into the audio output jack on your sound system. Sound system jacks  
typically are labeled “audio out,” “earphones” or “phones.”  
Note: There is a short, black ribbon attached to the interior of the battery  
compartment. Install the batteries on top of this ribbon and place the excess  
ribbon on top of the batteries. This ribbon will facilitate future battery  
replacement (i.e., to remove the batteries, simply grab the exposed ribbon  
and pull upwards).  
Note: With some sound systems, it will be necessary to install the  
supplied 1/4" adapter on the end of the Audio Cord in order to make the  
connection to the audio output jack.  
Battery Notes  
Follow these precautions when using batteries in this device:  
1. Use only the size and type of batteries specified.  
4. Turn the sound system on.  
5. Turn the Transmitter on. The ON/OFF Switch is located on the underside  
of the Transmitter base.  
2. Be sure to follow the correct polarity when installing the batteries as indicated in the  
battery compartment. Reversed batteries may cause damage to the device.  
The red LED will light confirming that the Transmitter is receiving power.  
If the LED does not light, make certain that all connections have been  
properly made.  
3. Do not mix different types of batteries together (e.g. Alkaline and Carbon-zinc) or old  
batteries with fresh ones.  
4. If the device is not to be used for a long period of time, remove the batteries to prevent  
damage or injury from possible battery leakage.  
6. Turn the Headphones ON. (This same control adjusts the volume on the  
right earphone).  
5. Do not try to recharge batteries not intended to be recharged; they can overheat and  
rupture. (Follow battery manufacturer’s instructions.)  
The red LED will light confirming that the batteries are providing power to  
the Headphones.  
7. Adjust the headband so that it fits comfortably.  
8. Adjust the left and right volume controls on the Headphones. (In the  
event of insufficient volume, check the volume control on the sound  
system).  
A FINAL WORD ABOUT THOSE AAA BATTERIES.  
To preserve the life of the batteries, always turn the Headphones OFF when  
not in use. If the red LED does not light when the headset is turned on, it is  
an indication that the batteries are not supplying sufficient power. Make  
certain the batteries have been properly installed or replace them with fresh  
batteries.  
DOESN’T SOUND RIGHT TO ME  
If you experience static or distortion in the Headphones:  
1. Check all connections.  
2. If applicable, make certain the sound system is tuned properly.  
3. Make certain you are within approximately 100 feet of the Transmitter.
