100 Corporate Drive Mahwah, NJ 07430 Service Bulletin No. : OST-F914 Date: June 14, 2007 _____________________________________________________________ Model: AVR-5805 Subject: Countermeasure for the malfunction reported from the market. Symptom: The following items 3) and 4) are modified for improving the specification. 1) When the Speaker Configuration for Zone 2 has been set to "Front = Small" and "Subwoofer = Yes" respectively, the output signal is not fed out from the Subwoofer-output during the Stereo Mode. 2) At the AUTO SETUP measurement, the unit misunderstands the signal as an detection error and there is a case to interrupt the measurement due to the malfunction of the distance-detection-processing. 3) After setting the Boundary Gain Compensation to ON, if the Subwoofer was set to "NO", the level of the low frequency range of main channels such as Front, etc., is lowered. 4) When a source that does not conform to the HDCP was inputted from DVI, the image is forcibly muted. Solution: Improved the software to resolve the symptoms outlined. MODIFICATION: (Upon Claim only) Please refer to the attached Manual and update the firmware on your customer's unit using the DENON Flash ROM Writer. Only update upon customer claim.
