Firmware Updates
As a responsible manufacturer, HHB adopts a policy of continuous product
development. As with all software-based products, it may be desirable from time to
time to update the firmware in your FlashMic with a more recent version. You can
contact your HHB dealer or distributor, or visit the FlashMic website at
http://www.flashmic.info for details of firmware updates.
Firmware updates are downloadable from the FlashMic website, or if you prefer,
from your local dealer/distributor on a CD-ROM. Alternatively, if you are uncertain
about performing a firmware update yourself, take your FlashMic to your HHB
dealer, who will be happy to do it for you.
It is recommended that the internal memory is reformatted after a firmware update.
See Reformatting the Memory for further details.
To perform a firmware update, proceed as follows:
First locate the firmware folder and file. Whether you have downloaded the
firmware from the FlashMic website or have it on a CD-ROM, it will always
be in a folder called FW VER xx-xx-xx, where xx-xx-xx is the firmware version
number. This folder will contain a file called DRM85.bin, which is the
firmware file itself.
Note that the firmware filename does not identify which version it is, therefore it is
important to keep it in the folder it ‘arrived in’ for identification.
Ensure that the batteries in your FlashMic are adequately charged, and
change them if there is any doubt. NEVER start a firmware update with
low batteries, as the FlashMic may be rendered unusable if the batteries run
out midway during the update procedure.
Turn the FlashMic on, and connect it to the computer with the USB cable.
The LCD display will change to USB, and the computer will signify its
recognition of the FlashMic in the usual way.
The FlashMic will be identified in the directory tree as an additional drive (the
drive letter will vary from machine to machine).
Drag-and-drop the DRM85.bin file to the FlashMic root (not into any of the
three folders AUDIO, CONFIG or FIRMWARE it contains).
When the file transfer is complete, unplug the FlashMic’s USB cable and
switch the FlashMic off.
Switch the FlashMic back on again; the LCD display will now show the
message UPDATE. The bargraph meter indication will start to move from
left to right. When it gets halfway, the FlashMic will turn off.
Switch the FlashMic back on again, and the update will continue
automatically. When the bargraph indication is full, the FlashMic will return
to IDLE mode.
The new firmware is now installed. It is suggested that the FlashMic memory
is now reformatted. See Reformatting the Memory for further details.
