CLEANING
• Clean with a dry, soft cloth
• A slightly damp cloth may be used to remove stubborn grime and dirt. Never use cleaners such as alcohol or thinner
• The M350 contains electronic circuitry that may cause interference if placed too close to radio or television receivers. If this occurs, move
the M350 further away from the affected equipment
SERVICE AND MODIFICATION
• There are no user serviceable parts in the M350
• Do not attempt to open the M350 or make any change to circuits or parts. This will void the warranty
PROTECTIVE CIRCUIT (POLY SWITCH)
The M350 is fitted with a self-resetting poly switch that protects the high-frequency driver from damage caused by excessive power. If a
loudspeaker cabinet loses high-frequency output, immediately remove power from the unit and wait for two to three minutes. This should be
long enough to allow the poly switch to reset. Reapply power and check the performance of the high frequency driver before continuing, with
the power reduced to a level that does not cause the poly switch to interrupt the signal.
INTERFERENCE FROM CELL PHONE
Using a cell phone near the speaker system can induce noise. If this occurs, move the cell phone further away from the speaker system.
