02/16 and 02/17 -

while initializing PM2 unit "A" on a different known point two different days with open sky, no obstructions, the unit looses lock repeatedly. when I did a code 32, both times and the unit performed the initialization and data collection the rest of the day without loss of lock.

any idea what is going on? have never had any trouble with the unit before 02/16.

thanks.

You mean . . . on each day you had to do a code 32?

yep.
