5. Keep the firmware update push-button (located next to the USB receptacle at the back of the unit) pushed while
powering-up the unit (by setting the Power on/off switch to on).
6. The unit will start up in firmware update mode and will update its internal firmware with the image present on the
USB stick. Do not interrupt or unplug the unit until the firmware update is finished. This typically takes about 5
seconds.

If the firmware update procedure fails, try to download the latest software images from www.ch-precision.com, use another USB
stick, and rerun the firmware update procedure (don't forget to prepare the software update files and USB stick accordingly). If
failure persists, contact your authorized dealer.
