On the other hand, if the update is underway and stops halfway through, then the firmware has been erased;
even though the instrument is completely fine, there is NO DAMAGE, but it will drain the battery fairly quickly.
To restore it, you will need to do a different kind of reset using 3 buttons that will reset the AIR and, at the same
time, bring it to bootloader mode:
o
Press and hold the 3
and
keys together.
o
Wait 5 seconds and then release the
key; the instrument emits a long acoustic “beep”.
o
First release the
key and then the
key. Now the instrument is turned on and it is in “boot loader
mode”, waiting for the firmware upload. Note: the screen will be totally blank at this point.
o
Resume from step 6) making sure the “Set COM” is on “Auto-search” and “Set speed” on “115200”.
