Improving Sound by Switching Channels
The CL7350 can transmit on either of two built-in
frequency channels. You can select the channel that will
produce better audio quality.
1. If the audio sound is distorted or unclear, press the Auto
Tune Button on the TV Receiver (see figure (7) at right), to
match the frequency of Channel 1 or Channel 2 set at the
back of Transmitter. Allow a few seconds for the audio to
resume.
2. If this does not help, switch the channel selector on the
rear of the Charging Cradle (see figure (8) at right) and see
if the audio quality has improved.
3. Press the Auto Tune button again to improve the quality
still further.
NOTE: The Transmitter will turn off automatically after
about 5 minutes if there is no audio signal from the audio
source (TV set, etc.), or the signal from the audio source is
too weak for proper reception. However, if the audio signal
returns to an acceptable level, the transmission will
automatically restart.
Controlling the Tone (Bass & Treble)
You can adjust the tone of the audio you are listening to and enhance your listening pleasure
Adjusting the Sound Balance (left-right)
You can adjust the sound to suit your hearing in each ear.
With the Receiver on, rotate the Sound Balance button (see
figure (10) at right) to adjust the sound – you will notice that
the sound seems to "drift" from one side to the other. Play
with this button until you find your most pleasant sound
balance.
