Updating Firmware

HQView-5xx accepts firmware downloads only in a dedicated Updater mode.

First disconnect the USB lead.

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.
