4. Updating of System Firmware
4-1. How to update of MCU rmware
4-1-1. Checking the firmware version Checking the firm-
ware version
Check the rmware version of AD-RW900/900E before starting
rmware updating procedures.
1) Turn the unit on.
2) Press the “COUNTER RESET” and “SOURCE” buttons at the
same time.
3) The current rmware version is shown at the bottom of the
display.
iAfter checking the version, press the “COUNTER RESET”
and “SOURCE” buttons at the same time again to restore
the usual display contents. (You can also turn the unit off
and on again to restore the usual display contents.)
4-1-2. Firmware update procedures
Copy the “player.rom” updater le to an empty USB ash
drive in advance.
1) Set the SOURCE to “USB”.
2) After “No USB” appears on the display, connect the USB ash
drive that contains the “player.rom” updater le to the USB
port.
3) After “READING” appears on the display, “UPDATING” will
appear for about 30 seconds while the rmware is being up-
dated.
注意
Do not disconnect the power cord or turn the unit off while
“UPDATING” appears on the display.
4) After about 30 seconds, “COMPLETE” will appear on the dis-
play.
5) Disconnect the USB ash drive and turn the unit o.
6) When you turn the unit on again, it will be using the new
rmware version.
