Quick Survey Base Mode: Select if exact location of
guidance tracks do not need to be stored for future
applications. If Quick Survey Base Mode is used to
establish rows or paths that will be used at a later date,
location of Track 0 must be saved using Current Field
setting in Tracking Setup (see AutoTrac Operator’s
Manual). When Current Field is recalled, a one-time use
of Shift Track feature will be needed to align vehicle on
previous tracks. See Setup Quick Survey Base Mode

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 Field in Tracking Setup 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 building or post
mounted in concrete.

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