3.5 mm stereo audio cable

User guide and quick-connectioninstructions

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 forstep-by-stepinstructions 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-outjack on your auxiliary audio device.

RCA connectors. To connect a device that uses RCAtype 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-supplystores.

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-toporwall-mounteduse. The factory default setting is fortable-topuse.

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 wallmounting bracket.

The speaker should only be mounted on the wall using a wall-mountingbracket provided by Altec Lansing. You can order thewall-mountingbracket online atwww.alteclansing.com. Go to the M812 product page.

3

Wireless Connectivity

The transmitter base and speaker can communicate over three wireless radio frequency (RF) channels. The default setting is AUTO. You may also manually select one of the three channels.

In AUTO, the transmitter base looks for and transmits on the most interference-freeof the three channels. The speaker searches the channels until it finds the base.

It is possible that the speaker and base may lose their synchronized connection from time to time. You may also experience interference with the connection.

If you experience interference or lose the connection between speaker and transmitter base, you can force the M812 to re-synchronize.To do so, press and hold down the STANDBY key on the transmitter base. After three seconds, the LED to the left of the STANDBY key will begin to flash. Continue to hold down the STANDBY key until the LED stops flashing (about six seconds).

If you continue to experience interference, check to see if you can eliminate the source by moving other devices that use the same RF spectrum. For instance, laptop computers that use 802.11 wireless networking can conflict with your M812 wireless connection.

If problems persist, you can manually set the radio frequency (RF) channel to channel 1, 2 or 3. To do so, follow the instructions in Advanced Operations under the headingSet RF Channels (page 8).

Listening To Your M812

Remote Control Operation

To control the M812, the remote control must be pointed toward the front of the speaker. (In a multi-speakersystem, any speaker that is synchronized can control the system.) The transmitter base does not have an IR sensor. Commands are transmitted to the base from the speaker. The M812 remote control uses twoAAA-sizebatteries.

Power and Input Selection

To turn on the M812, press the STANDBY key on the transmitter base or the POWER key on the side of the speaker or the remote control. Select iPod, FM or AUX by pressing the input selector on the speaker or using the remote control.

iPod

With your iPod docked in the transmitter base, turn on your iPod.

Press on the remote to start playing the iPod. (You can also presson the iPod itself.)

FM

To change the radio tuning, press oron the remote or the TUNE +/– keys on the speaker. Hold the key down to make the tuner scan to the next strong signal. Press the key repeatedly to manually adjust the tuning.

The M812 can store up to six of your favorite FM stations. To PRESET a station, tune to the desired frequency, then press and hold the desired PRESET key on the remote until PRESET shows on the speaker display.

AUX

To play music from an auxiliary audio device, connect the device to the transmitter base. Control music play back using the controls on the auxiliary device.

Volume

There are two levels of volume control: local and master. The range for local and master volume is 0 to 80.

Local volume affects only one speaker at a time. To adjust local volume, use the + and – keys on the remote control while pointing the remote control at the speaker that you want to adjust. You can also adjust local volume using the VOLUME keys located on the side panel of the speaker.

Master volume allows you to adjust all speakers in a multi-speakersystem from a single location. Master volume can be adjusted using the MASTER VOL keys on the remote control.

If you have a single-speakersystem, you may use master and local volume interchangeably.

Treble and Bass

To control treble or bass levels, press the TREBLE or BASS keys on the remote control. The display on the speaker will indicate the levels.

Reset

To reset your M812 settings, press and hold the POWER key on the side of the speaker for three seconds. See theAdvanced Operation section for more information on the reset function.

Advanced Operation

Multi-SpeakerSystems

With a single transmitter base, you can transmit audio to as many as eight wireless speakers. Speakers can be set to standard stereo mode or to serve as pairs of left and right speakers. By adding speakers to your system, you can create separate listening areas served by one or more speakers.

When you power up a multi-speakersystem, turn on the speakers first and then turn on the power to the transmitter base. This will allow synchronization between the speakers and the base. If one or more speakers fail

to synchronize or synchronization is lost during operation, you must re-synchronizethe system.

To re-synchronizethe transmitter base with the speaker(s), press and hold the STANDBY key on the transmitter base. After three seconds, the LED to the left of the STANDBY key will begin to flash. Continue to

hold down the STANDBY key until the LED stops flashing (about six seconds).
