The cabinet surfaces of the M1 Active Mk2 are covered with a vinyl laminate.
Clean these surfaces when necessary with a lint-free cloth dampened in warm
soapy water. USE ONLY A DRY CLOTH ON THE BACK PANEL OF THE
POWER AMPLIFIER. Do not attempt to clean the cabinet with a brush (which
may damage the surface) or a sponge (which may leave small crumbs in the
texture).
Do not attempt to clean either of the drivers.
The M1 Active Mk2/Surround speakers require no periodic maintenance.

We believe that the M1 Active Mk2 is one of the most reliable powered
monitors that can be made using current technology, and should provide
years of trouble-free use. However, should problems occur, DO NOT attempt
to service the unit yourself. Service on this product should be performed only
by qualified technicians. THERE ARE NO USER-SERVICEABLE PARTS
INSIDE.

Before sending the M1 Active Mk2s in for repair, make sure they are faulty
and that the problem isn't being caused by something else in the system.
Distortion or noise may be caused by a defective preamp, cable, equalizer etc.,
or a loose connection in the system. Connect the speakers to a system that is
known to be working properly to check whether the monitors have
malfunctioned.

Customers in the USA and Canada:
If the problem persists, call Alesis USA
at 1-800-5-ALESIS and request the Technical Support department. Talk the
problem over with one of our technicians; if necessary, you will be given a
return order (RO) number and instructions on how to return the unit. All
units must be shipped prepaid and COD shipments will not be accepted.
For prompt service, indicate the RO number on the shipping label. Units
without an RO will not be accepted. If you do not have the original packing,
ship the M1 Active Mk2 in a sturdy carton, with shock-absorbing materials
such as styrofoam blocks or “bubble-pack” surrounding the unit. Make sure
