Default North
Reference: True

Note: Apart from the Arrival and PDOP alarms,
MobileMapper Pro will generate a warning message on the
screen in each of the following two cases:
- "Low Memory." This message will appear when the
handheld is running out of memory. If a job is being
logged, then the occurrence of this message will auto-
matically stop GIS data logging. You will however be
allowed to enter the attribute values of the current fea-
ture before the job is closed.
- "Out of Memory." This message will appear when the
memory is full. The occurrence of this message will
immediately close the currently open job and you will
not be able to log any new feature until you free some
space in memory.
