RX-V2065/HTR-6295

■ UPDATING FIRMWARE

Note) The user memories (sound field parameters, system memory, tuner presetting, etc.) are preserved even after the
firmware is written.
When replacing the following parts, be sure to write the latest firmware.
Replaced parts
DIGITAL P.C.B.
IC20 (Main microprocessor) of DIGITAL P.C.B.
IC49 (TI (DSP) flash ROM) of DIGITAL P.C.B.
IC513 (BF (Sub-microprocessor) flash ROM) of GUI P.C.B.
● Confirmation of firmware version and checksum
Before and after writing firmware, check the firmware version and checksum by using the self-diagnostic function
menu.
Start up the self-diagnostic function and select "25. ROM VER/SUM/PORT" menu. (See "SELF-DIAGNOSTIC FUNCTION")
Using the sub-menu, have the firmware version and checksum displayed, and note down them.
