Merdian Platinum instructions (2 digit codes)

i own the Meridian Platinum unit but it has spent more time in the drawer
than in the field lately due to events in my life. i have moved to a
different state and now im trying to calibrate it. i know how to calibrate
the digital compass but i remember sometimes having to follow on screen
instructions about: "place unit on end until beep. place unit on front
until beep. etc" that gave a more in depth calibration.

i remember that if i hold down the NAV button while turning on the power to
the unit it will take me to a screen that asks for a 2 digit number. one
set of numbers would manually prompt the full calibration.

does anyone know what that number is?

does anyone have the full list of what all the 2 digit codes are designated
for?


thanks.
