General Maintenance

AC Voltage: Check that the rated voltage on the MX-Z3200M rear panel matches local voltage.
Placement: Avoid extreme heat, cold, dust, humidity, or vibration. Place on a flat, even surface. Maintain adequate space around the unit for heat dissipation (10cm top, 5cm sides/rear). Avoid airtight racks. Keep away from TVs/radios to prevent noise interference.
Safety: Pull the plug, not the cord, when disconnecting AC. Disconnect AC cord if not used for extended periods (small current flows even when off). Contact dealer for damaged AC cord.
Repairs: Disconnect AC cord and contact qualified service. Bring TX-Z9300, MX-Z3200M, and FX-WZ7300 together for repairs.
Copyright: Check local copyright laws for recording from discs, radio, or external tape.
