Check both the ‘View GNSS Level’
and ‘
Correct
Tilted Pol
e’
check boxes.
When in the Store or Stake screens, the top line
of the display will display an icon with the
current IMU initialization state.
If this icon is shown on the top line:
the IMU needs to be initialized.
The IMU can be initialized by allowing the
receiver to sit level for 15 or more seconds,
then dip the receiver in any direction 30
degrees and return to level, wait 15 seconds,
the IMU will initialize and the icon will change to
green:
Once the IMU is initialized it will remain
initialized if the receiver stays Fixed and pole
has some movement.
If the pole is held static for more than 30-
seconds, the IMU will report that it is
uninitialized, the smallest shake (0.01’) of the
pole will reinitialize the IMU for another 30-
seconds.
If the receiver drops to a FLOAT or DGPS
solution, the IMU initialization will be lost,
however the smallest shake of the pole after a
15-second period of FIXED readings will typically
reinitialize the IMU.
You may also see these IMU related icons:

configured ‘Level Tolerance’
or ‘Incline Tolerance’, see

measurement.
IMU Tolerance Settings
There are several IMU / Tolerance related
settings that will cause the top status line to ‘Go
Red’:
When the top line is red, any one or multiple
tolerance conditions will prevent you from
storing a shot, without overriding the action.
To configure the Tolerance settings, from the
main menu ‘
Equip: 8 Tolerances
’:
The ‘
Level Tolerance
’ is the
maximum allowable
linear ground distance error allowable.
