■ UPDATING FIRMWARE

Note) The user memories (sound field parameters, system memory, tuner presetting, etc.) are kept stored even when you

write the firmware.

When replacing the following parts, be sure to write the latest firmware.

● 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.
