AVR-391 AV SURROUND RECEIVER MODEL DHT-1311XP DHT-391XP 5.1CH HOME THEATER SYSTEM For purposes of improvement, specifi cations and design are subject to change without notice. Please use this service manual with referring to the operating instructions without fail. Some illustrations using in this service manual are slightly different from the actual set.
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.
NOTE FOR SCHEMATIC DIAGRAM WARNING: Parts marked with this symbol z have critical characteristics. Use ONLY replacement parts recommended by the manufacture 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.
When you update the fi rmware, you can use the following JIG (RS232C to internal connector conversion adapter with 4P FFC cable kit ). Please order to Denon Offi cial Service Distributor in your region if necessary. 8U-210100S WRITING KIT...
