SEVEN F REQUE NCY ASKE D QUESTI ONS (FAQ ) from marketing statistical analysis:
1.Outside noise overpowers the TV voice.
It is possible that the MIC ON/OFF button at the rear of headset is pressed on inadvertently, in this case the MIC
indicator is solid red . To back to watching TV, just press the MIC ON/OFF button again or switch off the headset
and then restart with the red MIC indicator off and the green TV receiving indicator on.
2.The connections are correct and in place, but no TV sound is heard or sound cuts in and out.
1) It is possible that the volume of the audio source is set too low. If you connect STB/Cable box/DVD etc to the
TV to watch programs, then the audio source is the STB/Cable box/DVD etc. Please use the audio source's
remote control to set its volume to a sufficient level to ensure a steady sound signal. If you want to mute the TV
sound and only hear from this headset, please use your TV remote control to click MUTE menu. (For most TVs,
the TV's speakers are separately controlled from the TV's audio out).
2) When do connection with the optical cable, set the Audio Out Format of your TV and TV related AV devices
(e.g., cable box/DVD etc ) to PCM to get the unit to work. ( Settings > Sound > Digital Audio Out Format >
