Sound module USM-RC-2
Firmware update
On the SD card is always located a firmware file for the sound module. The sound-
Teacher writes the firmware file automatically while saving project data to SD card.
Therefore you do not have to care about that.
A firmware update of the sound module is always performed automatically when the
version of a firmware file on the SD card is different from the current version of the
sound module firmware. The firmware update will be started after the supply voltage
is switched on and it takes about 10 seconds. The red and blue LEDs flashes during
this period a few times alternating.
You are not allowed to 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!
