FIRMWARE UPDATE
5.1.
Introduction
HQView-2xx has an USB port which allows a PC connection. With the Calibre PC Updater tool new
firmware can be installed on HQView-2xx for feature upgrades and bug fixes.
5.2.
Updating Firmware
HQView-2xx 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-2xx is in Updater mode. Otherwise,
HQView-2xx 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-2xx 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-2xx
into non-volatile flash RAM starts.
After completion of the download HQView-2xx needs to be restarted normally (without pressing the
Menu key) for the change to take effect.
This user manual complies with firmware revision 292A build 9693. Prior or later firmware revisions may
deviate in details or lacking of newly introduced features.
