Solution
Lower the volume level of the M812 by using the supplied remote
control or the VOLUME – key on the speaker.
Disable the EQ function of the iPod or turn down the bass on the M812.
Ensure the WALL/TABLE switch on the bottom of the M812 is set to the
proper position.
Move the unit to see if the interference goes away.
Move the GSM cell phone away from the unit.
Reduce the volume level. The M812 will automatically reset itself after
a short period of time. When the M812 resets it will come back in the
standby mode. Upon powering the unit back up, reduce the volume level
to prevent it from going into protection mode.
Set the MODE switch to the correct position: STEREO when one speaker
is used. LEFT or RIGHT when two speakers are used in the same room.
To manually regain synchronization between the transmitter base and
the speakers, hold down the STANDBY key on the transmitter base for six
seconds. The speakers will then synchronize with the transmitter base.
You can manually re-synchronize the speaker by holding down the
STANDBY key on the transmitter base for six seconds. The speaker(s) will
then synchronize with the transmitter base. This is only necessary if your
speaker has synchronized to someone's transmitter base that is in close
proximity to your speaker unit, as could be encountered in an office or
condo environment.
