This unit can show a position in degrees (36.14952°); degrees, minutes
and thousandths of a minute (36° 28.700'); or degrees, minutes, seconds
and tenths of a second (36° 28' 40.9"). It can also show position in: UTM
(Universal Transverse Mercator) projection; MGRS (Standard); MGRS
(Standard + 10); Map Fix; Loran TD; British, Irish, Finnish, German,
New Zealand, Swedish, Swiss, Taiwan, Greek and Military grids.

The military grid reference system (MGRS) uses two grid-lettering
schemes, which are referred to as standard and alternate MGRS on this
unit. The position and datum you are using determine whether you
should use standard or alternate MGRS. If you use standard, and your
position is off significantly, then try the alternate.
