To clean, be sure to first switch off the power supply to the unit, then wipe with a dry cloth.  When the unit gets
very dirty, use a cloth damped in a neutral cleanser. Never use benzene, thinner or chemically-treated
cleaning cloth because such volatile liquids could deform or discolor the unit. 

• When the EV-200 is mounted, never move the unit from one place to another with the Flash Card inserted

because the EV-200 or the CompactFlash card may fail. 

• Avoid inserting or withdrawing the CompactFlash card while the unit is alive. 

• Do not install the unit in locations exposed to the direct sunlight or heaters, as  the unit could be deformed or

discolored.

• Avoid installing or storing the unit in dusty or humid locations, as doing otherwise could cause the unit's

failure.

• Keep the unit as far away as possible from a fluorescent lamp, digital equipment, PC or other equipment

which generate high frequency noise.

• Do not block the ventilation slots on the upper, right and left, and rear sides to allow inside heat radiation. 

• Keep at least 50 mm space from the unit's right and left sides for heat radiation. 

• Never connect the AC power cord to any other line voltage than that specifically designated. 

• To avoid oscillation, keep the input cable away from the output cable. Particular care must be exercised

when mounting the unit in an equipment rack. 

• In some installations, a ground loop is formed and hum noise may be generated. In such cases, connecting

the rear-mounted signal earth terminal to the body of connected equipment (BGM sound source, expansion
amplifier, etc.) may reduce it.

• Never connect two amplifier outputs in parallel under any circumstances.

• When such work as mounting optional boards or setting switches needs to open the amplifier's top

cover, leave it to a qualified service technician. 

• In the case above, be sure to switch the power off before the work. 
• A warning that TERMINALS marked with the symbol 

are HAZARDOUS LIVE and that the

external wiring connected to these TERMINALS requires installation by an INSTRUCTED PERSON
or the use of ready-made leads or cords.
