something does no sound right, recheck your connections and settings. Re-measure, re-check, re-align.

12. Switch the processor/receiver to each input that you will use. Check your settings for each input and each

mode. Some processor/receivers require that you enter settings separately for each mode and/or input.

13. Before playing the system, check levels and speaker alignment one last time. Make sure that you write down

all processor settings for future reference.

12. IF YOU NEED SERVICE OR SET-UP ASSISTANCE

Contact your dealer or M&K with a complete description of the problem. Please have the unit's model and serial

numbers (found on the back of the cabinet), date of purchase, and your dealer's name. You can call M&K between
8:30 AM and 5:00 PM Pacific Time, Monday through Friday, at (310) 204-2854. If you call out

side these hours, leave

a message, and we will return your call promptly. Alternatively, an email can be sent to support@mksound.com.

DO NOT RETURN YOUR SPEAKERS TO THE FACTORY FOR

SERVICE WITHOUT OBTAINING PRIOR AUTHORIZATION

All M&K Satellite speakers carry a ten year limited parts and labor warranty. This warranty is transferable to new

owners up to ten years from the date of original purchase. It does not cover abuse, misuse, repairs by unauthorized
service stations, speakers without M&K serial numbers, speakers not sold by authorized M&K dealers, and those
damages in shipping or by accident. If you have any questions about the warranty, please contact M&K.

13. CABINET MAINTENANCE

Treat the cabinet as you would any piece of fine furniture. Its black or white vinyl finish does not require any

special maintenance; regular dusting with a lint-free cloth and periodic cleaning is all that is required. Do not use any

solvent based cleaners, as they may damage the cabinet surface.

14. USE WITH M&K ST-WALL BRACKETS

The Bookshelf-75 and LCR-55MkII speakers contain a threaded (3/8") insert, as well as a set ot two threaded

1/4"-20 inserts, located on the speaker's back baffle. Using the appropriate screws, you can fasten the speaker to an
M&K ST-series speaker stand or M&K ST wall mount brackets. The LCR-45 will require the ST-BT5 bracket. Both the
M&K stands and brackets offer tremendous flexibility for installation in a wide variety of environments and both are
available in several configurations. This mounting scheme can also be used with Omnimount brackets.
