If you experience problems while using this product, try the following solutions. If you still

Team direct at 877-335-2673 to arrange for service.

Recommended troubleshooting tools:

• Portable voltmeter

• Cable tester

• AC outlet tester

• XLR and ¼-inch phone plug cables

What to do

• Make sure you have power at the AC outlet. Try operating a lamp or other equipment

from the same AC outlet or test the outlet using an AC outlet tester.

• Make sure the L1 model I power stand's power cord plug is fully inserted into the

AC outlet.

• Check the line fuse on the L1 model I power stand.

• Make sure volume control is turned up on your instrument.

• Make sure the applicable level control is turned up (Trim, or Channel 3/4 Level on the

L1 model I power stand; CH 1/2 LEVEL and MASTER level on the R1 remote control).

• Make sure your instrument is plugged into the Channel 1/2 Input or Channel 3/4 Input

jack.

• Connect your instrument to the L1 model I power stand using a different cable.

• Plug your instrument into a different amplifier to make sure the instrument is working.

• Please call Bose Live Music Customer Support at (877) 335-2673 for assistance.

• If you have more than one L1 model I power stand plugged into the same AC circuit,

stagger the turn-on times. Each L1 model I power stand has an inrush current of about

32 amps when turned on.

• If you have more than three L1 model I power stands plugged into a single 15 amp

circuit, move some systems to another AC circuit. Each L1 model I power stand can

draw 5 amps or more when playing at high volumes for long periods of time.

• Using an AC outlet tester, test the AC outlet that the L1 model I power stand is plugged

into for reversed or open (hot, neutral, and/or ground) contacts.

• If using an extension cord, make sure that the cord is also tested as above.

• Make sure you are using the (blue) B1 bass module 4-wire cable included with the B1

bass module.

• Make sure that the B1 bass module cable is plugged into the B1 Bass Module jack on

the L1 model I power stand.

• Try a different 4-wire cable.

• Check that the B1 bass module cable connectors are fully engaged in the jacks.

• If available, try a different B1 bass module.
