Absolute Survey Base Mode Select if exact location of
guidance tracks need to be stored for future guidance
applications without relying on visual reference for track
position to align using Shift Track feature. Track 0 must
be stored using Current Track 0 in Guidance Setup – Set
Track 0 in order to follow previously used tracks. Absolute
Base Mode requires 24-hour self survey to be conducted
on location before first use. After survey is completed,
base station will then transmit corrections. If base station
is moved to another position and then returned to original
surveyed position, it is very important that base station is
mounted in exact same position. Any difference between
original surveyed position and mounted position will result
in offset of corrected position. For this reason, it is
important to mount receiver to a fixed position like a
building or post mounted in concrete.

OFF Mode This mode disables all RTK functionality in
receiver. RTK Operating Mode must be OFF for normal
SF1 or SF2 operation on SF2-licensed receiver.
