(only when use as a wireless headphone).
The audio signal input level is too low. Increase the volume
from the audio source of Hi-Fi, CD, or TV, etc.
The connected audio/video equipment may not be in playback
mode. Start playback on by the equipment.
The headphones output level is set too low. Adjust the volume
to a suitable level.
Distortion
Restart the Pairing process.
The headphone’s batteries charge level may be too low.
Recharge the batteries.
Ensure that the volume setting is correct.
The headphones may be too far away from the base. Move closer
to it.
The audio signal input level is too strong. decrease the volume
from the audio source of Hi-Fi, CD, or TV, etc.
Note:
In the event of the television not having the standard red and white audio
output RCA, or the audio jack, then it is most likely the TV will have an
optical audio output. By purchasing a Geemarc optical converter (our
reference CL7XX_OPT) this will allow the CL7400 to connect to the TV's
optical output successfully.
