YOUR SL2 WIRELESS SURROUND LINK
Getting ready
Thank you for choosing a Bose® SL2 Wireless Surround Link. It provides a simple and 
convenient
 means to enjoy the surround sound from your LIFESTYLE® system or 
powered
 Acoustimass® system.
The SL2 features a small radio frequency transmitter and receiver pair that delivers the left 
and right surround audio signals, complete with amplification, to surround speakers in the 
rear of your room. Running cable from the front to the back of the room is unnecessary.
Unpacking the carton
Carefully unpack the carton and save all packing materials, which provide the most secure 
way to transport the product. 
Check to be sure your system includes all of the parts shown (Figure 1). If any part appears 
damaged, do not attempt to use it. Notify Bose or your authorized Bose dealer immediately. 
For Bose contact information, refer to the address sheet included in the carton.

If you have not yet done so, now is a good time to find the serial number on the bottom of the 
SL2 transmitter, then copy it in the space provided on 
“For your records” on page 3.
Setting the transmitter for your system
If your speakers are part of an Acoustimass® speaker system, you need to set the switch on 
the bottom of the SL2 transmitter to Other (
Figure 2).
Figure 2
Speaker switch 
Bottom of the 
SL2 transmitter
Switch
For use of a LIFESTYLE® system with the SL2 Wireless Surround Link, the current default 
switch setting is optimal. There is  no need to change the setting.
Important note: Running the ADAPTiQ® audio calibration system, which is provided with your 
LIFESTYLE® system, helps ensure the most  accurate sound from your system. Be sure to use it 
after the SL2 is connected and your surround speakers are in the final position.
Choosing positions for your  SL2 transmitter and receiver
Radio frequency transmissions make this product easy to place. It is seldom necessary to 
point the SL2 transmitter at its receiver. This allows you to hide both from view if you like.
The SL2 transmitter, identified on the label,  is also distinguished by a single input jack 
(see
 Figure 3 on page 6). The SL2 receiver, which is also  labeled, has two output jacks.
1. Place the SL2 transmitter within 61/2 feet (2 meters) of the Acoustimass® module. 
Make
 sure it is within reach of an AC (mains) outlet. 
2. Place the SL2 receiver at the same end of the room as your surround speakers.  It,
 too, should be within reach of an AC (mains) outlet.
Position the transmitter/receiver pair:
From 61/2 feet (2 meters) to 30 feet (9.2 meters) apart.
 Where the sides are unobstructed to allow for ventilation.
 Upright (neither upside down nor on a side) on the floor or other flat, stable surface.
Note:  If you experience any problem with communications between the SL2 transmitter 
and receiver, positioning them within line of sight to each other may be helpful. For further 
suggestions on how to deal with such problems, refer to “Troubleshooting” on page 9.

Connecting the SL2 receiver
Use the supplied 20-ft (6.2-m) cables to connect the speakers to the SL2 receiver. Or, you may 
prefer to use the longer surround speaker cables that came with your speakers. 
Note: To use the SL2 supplied cables with Jewel Cube® speakers, first attach a Jewel Cube 
adapter to each cable as described in “To adapt the surround speaker cable for Jewel Cube® 
speakers” on page 8.
To make the receiver connections
Using the supplied cables, follow the steps below:
1. Insert the RCA connectors into the jacks on the back of the SL2 receiver (Figure 5).
 Connect the purple one marked RR to the purple jack labeled RR.
 Connect the green one marked LR to the green jack labeled LR.
2. Connect the wire ends of the cable to your surround speakers.
 Insert the wire marked RR into the terminal on the speaker that is placed  
on the right. 
 Insert the wire marked LR into the terminal on the speaker that is placed  
on the left. 
For details on how to set up and make connections to your surround speakers, refer to 
the owner’s guide provided with them.
3. Connect the cable end of the receiver power pack to the small jack labeled DC Power on 
the back of the receiver. 
4. Connect the power cord to the receiver power pack and insert the power cord plug into a nearby AC (mains) outlet.

When this power supply is plugged in, the Status LED on the back of the SL2 receiver blinks 
green until it links to the transmitter. If the transmitter has no audio signal to communicate to 
the receiver, the LEDs on both units turn orange. When the two are communicating with each 
other, their LEDs turn a solid green.
For an explanation of the other LED colors, refer to “What the Status LEDs indicate” on 
page 8.

Using this cable with the adapters attached, follow the steps in “To make the receiver 
connections” on page 7. Be sure to match each adapter to the proper speaker, right or left.
What the Status LEDs indicate
On the rear of the SL2 transmitter and receiver, the color of the Status LED indicates how 
each unit is functioning. With the power pack plugged in, the LED lights as follows:
 Blinking green: when one unit is trying to link to the other.
 Solid orange: in sleep mode for low power use when there is no audio signal to  
communicate.
 Solid green: the receiver and transmitter are communicating with each other. 
This green LED stays lit for several minutes after communications cease.
 Blinking red: the SL2 receiver is too hot, or there is a problem with the surround speaker  cable connection between the SL2 receiver and the speakers.
For information on how to deal with a blinking red LED, see “Troubleshooting” on page 9.

Troubleshooting
ProblemWhat to do
Blinking red Status 
LED on either the 
SL2 transmitter or 
receiver Disconnect the unit from the AC power outlet.
 Remove any possible obstruction to ventilation and reposition the unit upright with 
clear space around the ventilation openings on each side. If the ventilation was 
obstructed, allow the unit a few minutes to cool before reconnecting it to the AC power 
outlet.
 If it continues to blink red, check the cable connection between the SL2 receiver and the surround speakers. Make sure the connections are secure and the cable wires are 
not touching each other, which can cause a short circuit. Refer to 
“Connecting the SL2 
receiver” on page 7. Reconnect the unit to the AC power outlet.
 If it continues to blink red, unplug the unit from the power outlet and contact Bose® 
Customer Service. Refer to the address list included in the SL2 carton.
No sound or 
intermittent
 sound
 Make sure the audio source is playing and the program selected includes surround  sound audio.
 Check to be sure both the SL2 transmitter and receiver power packs are properly plugged into functioning AC power outlets. Refer to 
“Making the connections” on 
page 6.
 Make sure that cables are properly connected to the SL2 transmitter, the Acoustimass® 
module, the SL2 receiver, and the surround speakers. The connectors must be 
inserted securely in the jacks.
 Make sure the SL2 transmitter and receiver are no less than 61/2 feet (2 meters) and no 
more than 30 feet (9.2 meters) apart.
 Locate the small opening labeled Reset on the bottom of both the SL2 transmitter and  the SL2 receiver. Using a fine-pointed tool (like a straightened paper clip), press inside 
the opening on the transmitter. And, within 30 seconds, in the same way press inside 
the opening on the receiver. 
 Move the receiver, the transmitter, or both so the transmission path between them does not intersect with large metal objects in your room or other obstructions (like a 
fish tank full of water). 
Interference with a 
wireless (5.8GHz) 
phone  Increase the distance from each SL2 unit to the phone.
 Press the channel button on the phone (if one is provided) to choose a different channel
 for phone transmissions. 
Contacting Customer Service
For additional help in solving  problems, contact Bose Customer Service. Refer to the address 
sheet included in the carton.
