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
by amplifying either the Treble or the
Bass in the Headset Receiver.
Press the Tone Clarity Button to
switch cyclically between :
1. Enhanced treble (yellow LED glows
),
2. Enhanced bass (blue LED glows
), or
3. Flat tone (bass and treble equally
enhanced, no LEDs glowing ).
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.
Using the Mic Button and Microphone
for Conversation
You can switch from Listening mode to Conversation mode
without having to take off the Receiver.
To talk or listen to someone:
1. Press the Mic button (see figure (11) at right). This will
shut off the Audio Source and the Receiver will become an
amplifier by activating the Microphone.
2. To resume listening to your audio device, press the Mic
button again. The microphone will be shut off and the audio
will resume.
Charging the Battery
1. The signal LED Indicator on the Headset Receiver will
blink slowly when the battery level is low. At this stage
there are about 20 minutes of operating time before the
Headset will switch off. Recharge the battery.
2. Switch OFF the On/Off Switch on the Headset (see
figure (12) at right). The green LED on the Headset should
turn off.
3. Place the Headphone on the Charging Cradle (see
figure (13) at right), make sure the charge contact touches
the charge pins on the Charging Cradle.
4. The Charging process starts automatically.
• The LED Indicator glows red during charging.
• It will glow in green after the battery is fully charged.

The battery must not be exposed to excessive heat such as
sunshine, fire etc.
Do not attempt to replace the original rechargeable battery.
When the headphones are not in use, move the switch to the OFF position to avoid
damaging the batteries.
The battery must always be fully charged before first use. An initial 3 hours charge is required
