16-1. F/W Upgrade method
If the firmware is required to be updated for correction of bugs found
after mass production, the F/W should be upgraded according to
the following procedure:
(1) Connect the AC adapter and supply power from an AC outlet.
(2) Connect the set with a PC via USB and copy the following
file to the root directory in the Nancy drive. (This file is
distributed for correction of bugs found.)
* MSFWUPGR.UPG (file for upgrade)
(3) Ensure the copy is complete and disconnect USB connection.
(4) Set TEST MODE and select “F/W Update”.
(5) Press
u
key to start the F/W Update.
(6) The OPE-LED is lit red to green to orange and then lit out.
Now the update is complete.
(7) Select “Version” in TEST MODE and check the version.
NOTE:
The upgrade will fail if the power is off or RESET is pressed during
upgrade.
(This will result in malfunctions such as power not turned on and
incorrect operation during operation of the set.)
If this problem occurs, the set need be disassembled for upgrade.
Contact the Design Department.

microphones due to variations in sensitivity dependent on the single
microphone.
*
Provide an anechoic box.
*
Install a speaker and a set stand in the box.
*
Fix the set on the stand. (The set should face the speaker
straight.)
*
