Updating the PAM firmware
=========================

Common way:
- Enter menu SETUP/UPDATE, the PAM will enter SERVICE menu

- Go back and select UPDATE
- Connect the USB key and wait for update completion
- Disconnect the USB media and apply a power cycle


Emergency way (to be used with old firmware 1.0A/1.0B or in case of power failure during update):
- Power OFF the module
- Press and hold both buttons (MENU + BACK) and apply power, the PAM will enter SERVICE menu
- Select RESET and confirm (this will reset the configuration)
- Go back and select UPDATE
- Connect the USB key and wait for update completion

Note: if the module doesn't have any calibration data, it will display an error message
To remove that error message, enter the hidden menu SETUP/INFO and long press the MENU button until the DADC CAL menu is displayed. Select SAVE.
