For Europe model SERVICE MANUAL MODEL DHT-500SD Ver. 3 Please refer to the MODIFICATION NOTICE. HOME THEATER SYSTEM HOME THEATER SYSTEM (DHT-500SD) consists of DVD SURROUND RECEIVER (ADV-500SD) and SPEAKER SYSTEM (SYS-500SD).
DHT-500SD SAFETY PRECAUTIONS The following check should be performed for the continued protection of the customer and service technician. LEAKAGE CURRENT CHECK Before returning the unit to the customer, make sure you make either (1) a leakage current check or (2) a line to chassis resistance check. If the leakage current exceeds 0.5 milliamps, or if the resistance from chassis to either side of the power cord is less than 460 kohms, the unit is defective.

DHT-500SD NOTE FOR SCHEMATIC DIAGRAM 配線図について 1. WARNING: Parts marked with this symbol have critical characteristics. Use ONLY replacement parts recommended by the manufacturer. 2. CAUTION: Before returning the unit to the customer, make sure you make either (1) a leakage current check or (2) a line to chassis resistance check. If the leakage current exceeds 0.5 milliamps, or if the resistance from chassis to either side of the power cord is less than 460 kohms, the unit is defective.
