talking to the service personnel as the situation entails. To see the HW/SW version, scroll to
SET_MENU>MAINTENANCE> HW_SW_VERSION and and press the wheel to invoke ENTER. The
hardware and software versions will be displayed.
6.3. Check update
The check for possible firmware updates, you can connect to the update server of the manufacturer.
Scroll to SET_MENU>MAINTENANCE>CHECK_UPDATE and and press the wheel to invoke ENTER. A
check for an available update will be expedited. You will be prompted for the update if there is one.
Interrupting the power supply in the course of update might damage the flash memory permanently
and render the DMW300 useless. Hence only confirm to expedite a firmware update when no power
supply interruption is to be expected. Note that the warranty will be void if the DMW300 is diagnosed
to have a firmware-update related memory damage.
The update firmware is contained in a compressed package to be downloaded to the DMW300 when
the user confirms the update to be expedited. The received compressed package will be decom-
pressed and applied automatically. When the update is done, the DMW300 will prompt you for a
Restart. Press the wheel to invoke ENTER to restart and the DMW300 will have the updated firm-
ware in operation upon powering up again. If there is no update, the DMW300 will display "Already up
to date". Normally, when you power up the unit, when Internet is connected, it will automatically check
with the Update Server for any available firmware update. If there is new update, a pop up window will
prompt you to update the unit. If you do not take action, the pop up window will disappear in 10
seconds. However, you can always do the manual check and then update later.
Please note that there are two components, kernel and applications, that might need to be updated.
You will be prompted for an update in sequence if the new update contains both components. Just
follow the steps as you are prompted. Depending on the specific update required and the bandwidth
during the transmission, the file transmission, decompression and installation may take from 2 to 10
minutes. If you have not quite kept up with the firmware update, chance is that you might have to go
through more than one upgrade for each component. For example, your DMW300 is using rev 1.2
firmware and the latest firmware is rev 1.8. Depending on the situation, you might have to step
through some or all of the previous upgrades in order to properly upgrade to rev 1.8.
6.4. Factory default

presets for FM radio and WEB radio. Use this with extreme care under the instruction of the service
personnel as and when required. To reset the unit to factory default settings, scroll to
SET_MENU>MAINTENANCE>FACTORY_DEFAULT and press the wheel to invoke ENTER. You will be
prompted to confirm the reset. Press the wheel again to invoke ENTER and the unit will be reset to
