OPERATION
1. Switch on the sound source (TV, PC, VCR, DVD player or audio component) that
the transmitter is connected to.
2. Place the headphones On/Off switch in the On position.
3. Before placing headphones on head, make sure the volume is not too loud and then
place the headphones on your head and adjust the volume to obtain the desired
sound level.
4. There are 3 available channels. Press the Auto Scan button on the headphones to
search for the best reception. The corresponding indicator light will illuminate.
NOTE: You should then be able to move freely from one room to another with no
interference. If interference does occur (interruptions in the signal), press the Auto
Scan button once to find a better reception channel.
A For better stereo reception, stay approximately 23 feet away from the transmitter
when you press Auto Scan.
B If it is impossible to find a satisfactory frequency, change the channel setting
(CHANNEL 3 x2x1) on your transmitter, then press Auto Scan to find the
corresponding channel.
To protect the transmitter and save power, the transmitter will automatically switch off after
approximately four minutes if the signal from the audio source is too weak. If, however, the
signal returns to an acceptable level, the transmitter automatically switches back on.
ATTENTION:
The transmitter for this wireless stereo headphone set is designed to work with a
wide variety of devices. Our tests have shown the default volume levels of iPods,
MP3 players and other devices connected to the transmitter through the
headphone jack does not have the signal strength required by the transmitter.
Raising the volume of your device will increase the signal strength to the
transmitter. The red signal LED will light when the required signal strength from
your device if reached. We recommend that you keep the volume set on your iPod
or MP3 player at a minimum of ¾ of full volume.
