Model: AVR-2106, AVR-1707, AVR-1907, AVR-1507, AVR-886, AVR-787,
AVR-687, AVR-587, AVR-487
Subject: Countermeasure for improving the functionality of the UNIVERSAL®
REMOTE CONTROL (MRF350).
Countermeasure is only for a claim from the customer.
Symptom: When controlling the Denon AVR receiver with the MRF-350 (BASE
STATION) and MX-900 (Remote Control) manufactured by UNIVERSAL®
REMOTE CONTROL, the UP/DOWN operation of the Volume Control will stop if
the VOL UP/DOWN Button is hit frequently or continuously. The malfunction is
due to a bug in the AVR MICON.
Solution:
Replace IC201 with the new MICON. (You cannot rewrite the software since it is
not a Flash type MICON.) The Version of the MICON firmware after replacement
is: XM45
2) For the models
1707 and AVR-1907:
Rewrite the MICON software using the improved MICON Program.
