5.2.
Updating Firmware
HQView-5xx accepts firmware downloads in a dedicated Updater mode. The unit is put in Updater
mode by pressing and keeping the Menu key pressed at power up. If the Menu key is released within
10 seconds after power up HQView-5xx is in Updater mode. Otherwise, HQView-5xx is started
normally. Whilst the Menu key is still pressed the On LED is flashing. When in Updater mode the On
LED is flashing two times, then switched off, then flashing two times again, then switched off and so
forth. Now the USB connection between PC and HQView-5xx needs to be established and the Calibre
PC Updater tool to be started. The PC Updater tool allows to browse and select a firmware file in
BREC format. Once a BREC is selected the Update Firmware button has to be pressed and the
firmware download to the HQView-5xx into non volatile flash RAM starts. After completion of the
download HQView-5xx needs to be restarted normally (without pressing the Menu key) for the change
to take effect.
