Handling Precautions; Installation Precautions - Toa SV-200M Instruction Manual

4. HANDLING PRECAUTIONS

[VM-2120/VM-2240 and RM-200M/RM-210]
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.
[VM-2120/VM-2240]
• 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.

5. INSTALLATION PRECAUTIONS

[VM-2120/VM-2240 and RM-200M/RM-210]
• 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.
[VM-2120/VM-2240]
• 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.
At least 50 mm
• 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.
Caution
• 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
external wiring connected to these TERMINALS requires installation by an INSTRUCTED PERSON
or the use of ready-made leads or cords.
