Firmware update
The sound-Teacher writes the firmware file automatically while saving the project
data onto SD card.
A firmware update of the USM-RC-3 is always performed automatically when the
Sound-Teacher version is different from the current version of the USM-RC-3
firmware. The firmware update will be started after the supply voltage is switched on
and it takes 10 seconds. The red and blue LEDs flashes during this period a few
times alternating.
Never disconnect the sound module from power supply while updating!
A new firmware is mostly included if you are using a new version of the Sound-
Teacher. If you are using a new version of the Sound-Teacher, take care that on the
first turning on of your sound module, the firmware might be updated. Therefore the
voltage should not be turned off for at least 10 seconds!
