lows, the device may not be searched or connected
properly.
-If there is strong electromagnetic interference.
-If there are many Bluetooth devices in the area.
-If the headset is turned off, not in place or has an
error.
-Because products such as microwave oven, wireless
LAN, plasma light, gas range etc., use the same fre-
quency range, they can cause communication errors.

off etc. will not be automatically recovered. Try con-
necting the applicable device again.

GMono headsets may suffer from noise as the dis-
tance from the TV increases, because they use a
different transmission method compared with
stereo headsets.

Volume +/- and MUTE keys do not work, and
the Audio menu returns to the default value
and is disabled.
