UPGRADE INSTRUCTIONS

Marsa54L Build 12 and Earlier - !! CRITICAL !!

YOU MUST HAVE AT LEAST ONE FLIGHT RECORDED ON THE ALTIMETER

Num Flights cannot be 0

If you have an earlier Marsa54L with no flights, simply run a simulation flight on the altimeter before upgrading the firmware.

This is done by holding the joystick to the left while powering up the Marsa54L.  The altimeter will then run a simulation flight.
Then Upgrade the firmware by the standard process in MarsaConnect.

Marsa54L Build 17 and later - MarsaNet

Upgrade the firmware by the standard process in MarsaConnect.
