Wireless Speaker System for iPod. The M812 includes 
one or two wireless, high-performance speakers and a

models, FM radio stations and auxiliary audio sources. 
Music is wirelessly transmitted from the base to the 
speaker. Since the speakers are wireless, you can place 
them almost anywhere in your home. Basic playback 
functions for the iPod can be controlled with the supplied 
remote control.

Set up and basic operation
Set Up
The wireless capabilities of the M812 make it easy and 
flexible to set up. The transmitter base can be located up 
to 100 feet from the speaker, so you can place speakers 
for best sound and the base for convenient access. 
See the M812 Quick Start Guide for step-by-step 
instructions for quick set up of your M812 system. In 
this booklet, you’ll find more detail on connections and 
operation. After making connections, turn on the speaker(s) 
first and then turn on the power to the transmitter base. 
This allows the base and speaker(s) to synchronize more 
easily. If synchronization does not take place, see Wireless 
Connectivity for more information (page 4).
Transmitter Base
The transmitter base serves as an iPod dock and FM 
tuner. It has rear connectors for auxiliary audio sources 
and the power adapter. 
iPod Dock
The M812 works with iPods that have a dock connector 
(Generation 3 iPods and newer.) To use an iPod with 
the M812, install the appropriate adapter plate into 
the universal dock. Adapters for several different iPod 
models come with the M812. Other adapter sizes may be 
supplied with your iPod or be available from Apple.
Auxiliary Audio Devices
The M812 supports auxiliary audio sources such as 
portable CD players.
Connect one end of the supplied 3.5 mm stereo cable 
into the auxiliary input jack (AUX) located on the back 
of the M812 transmitter base, and the other end to the 
headphone or line-out jack on your auxiliary audio device.
RCA connectors. To connect a device that uses RCA-
type output jacks, you must use an adapter to convert 
the RCA output to a 3.5 mm input. These adapters are 
available at most electronics-supply stores.
FM Antenna
Attach the supplied FM antenna for FM reception.
Power Supply
The transmitter base is powered by the power supply 
that comes with the M812. Connect the power supply 
to the transmitter base, then plug the power supply into 
a wall outlet. 
Wireless Speaker
The supplied power cord attaches to the back of the 
wireless speaker.
Speaker Settings
Two switches are located on the back of the speaker. The 
location switch allows you to set the speaker for table-top 
or wall-mounted use. The factory default setting is for 
table-top use.
The mode switch allows you to set the speaker for stereo 
sound or as the left or right speaker in a pair of speakers. 
The factory default setting is stereo.
Wall Mounting A Speaker
The wireless speaker can be placed on an appropriate 
level surface or mounted on a wall using the optional wall-
mounting bracket. 
The speaker should only be mounted on the wall using 
a wall-mounting bracket provided by Altec Lansing. 
You can order the wall-mounting bracket online at 
www.alteclansing.com. Go to the M812 product page.
