4. HANDLING PRECAUTIONS
• Keep the input cable away from the output cable. If installed close to each other, oscillation could occur.
• To avoid unit failures, never connect outputs of two or more units in parallel.
• Only connect speakers with an impedance equal to or greater than those specified. Connecting speakers
with a smaller than specified impedance could cause damage to the unit.
• Periodically clean the filter located inside the ventilation panel on the unit's front panel. If the filter becomes
clogged, heat will become trapped inside the enclosure.
• Install the unit in locations where the temperature is between –10 and +40°C and the moisture is less than
90%RH (no dew condensation must be formed).
• To clean, be sure to first switch off the unit's power, then wipe with a dry cloth. When the unit gets very dirty,
use a cloth damped in a neutral cleanser. Never use benzene, thinner, alcohol, or chemically-treated
cleaning cloth because such volatile liquids could deform or discolor the unit.
