NOTE: The auxiliary coordinate file created during a

the prefix is different (“A” instead of “G”).
• MobileMapper 10 and MobileMapper 6 raw data files are
named as follows:
nnnnyymmddss.grw
Where:
NOTE: The coordinates file created during a working
session uses the same naming convention. Only the
extension is different (”crw” instead of “grw”).
• During raw data collection, even if you are not logging any
feature but just moving from one feature to another,
remember you should keep holding the receiver at an
angle of 45° above the horizontal.
• Never switch the receiver to suspend mode while
collecting raw data (this would end raw data collection). If
you want to save battery power while collecting data, you
may turn off the screen backlight. However, if you are also
using the e-compass while collecting raw data, remember
the backlight setting must be left unchanged. It must stay
as was set when you last calibrated the e-compass.
• Always collect raw data for at least 10 minutes, including
for those projects where GIS feature collection can be
completed in less time. Remember the more you collect
