the speaker (when
connected to PC
or laptop).
The sound is distorted.
Intermittent buzzing.
The wireless speaker
stops playing or cuts out.
It appears that the
wireless speaker is
not reproducing a
stereo signal.
I have three speakers
connected to one

lost sync and now it
will not automatically
re-synchronize.
My speaker is picking
up music from a
different source.
NO SYNC shows on
speaker display.
The LCD displays "iPod,"
and the iPod is playing,
but no sound is coming
from the speaker.
iPod does not function
properly when docked to
the transmitter base.
Possible Problem
The operating system's volume level
is set too high.
Interference.
The M812's volume level is set too
high.
The EQ function is enabled on the
iPod and there is too much bass.
The WALL/TABLE switch on the
bottom of the wireless speaker is in
the wrong position.
The unit is located too close to a
GSM cell phone.
The M812 has gone into an over-
current, protection mode.
The MODE switch on the bottom of
the unit is in the wrong position.
In a multi-speaker system if a single
speaker loses synchronization that
speaker unit will not be able to
automatically regain synchronization.
Your speaker has synchronized to
another transmitter base that is within
range of your speaker.
Synchronization between speaker
and transmitter base has failed.
The speaker and transmitter base
have a poor connection.
You may need to update the software
on the iPod.
Solution
Check the operating system volume level and
decrease it if necessary.
Move the unit to another location or select a
different RF channel.
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 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 POWER key on the speaker for
six seconds. The speaker will then synchronize
with the transmitter base.
Disconnect the speaker power cord from the
wall outlet, wait 30 seconds, reconnect to the
outlet and power on the speaker. Press and hold
the STANDBY key on the transmitter base for
six seconds. If situation persists, you may need
to manually set the RF channel. See Set RF
Channels in Advanced Operations (page 8).
Press and hold the STANDBY key on the
transmitter base for six seconds. This will cause
the speaker to re-synchronize with the transmitter
base.
Go to the Apple Web site and follow the
directions to upgrade your iPod to the latest
software.
