Firmware updates

The FH-1's firmware can be updated from a USB flash drive. The process is as follows:
  • Download the firmware from the Expert Sleepers website.
  • Unzip the download.
  • Copy the file 'image.hex' from the unzipped download to the root folder of a USB flash drive.
  • Turn off the FH-1 and insert the USB flash drive.
  • Turn on the FH-1. It will go through its startup sequence as above. At the stage where LEDs H/8 flash alternately, if the FH-1 finds a USB flash drive with a file named 'image.hex' on it, it will proceed to the next step.
  • LEDs A-H will flash alternately with LEDs 1-8. This indicates the FH-1 is waiting for your confirmation before proceeding. At this point, spinning the encoder will cancel the upgrade process and the FH-1 will continue to boot its current firmware. To continue with the firmware update, press and hold the encoder for one second.
  • When the update starts, LED B will light and LEDs 1-8 will flash to indicate progress. Do not remove the flash drive or turn off the power during the update.
  • When the update is complete, the FH-1's usual boot process will resume.
