SERVO AND BIAS
servo mode
1. Tracking：AAT real-time automatic control servo.
2. Offline：Keep the last moment;If the signal is lost or the AAT tilt angle is too
large,it will automatically enter offline mode.
*Please try to ensure that the device is stationary when powering up.
servo bais
1. bais1：Horizontal servo bais,1 degree at a time.
2. bais2：Vertical servo bais,1 degree at a time.
YWA/PITCH1/2
Accurately set the range of servo motion,avoid dead zones caused by a larger or smaller
range of motion angles than normal.
CALIBTATION
Compass calibration：
(1) Enter calibration:<KEY OPERATION>.
(2) Calibration step:vertical and horizontal for 3 turns.
(3) Verify calibration:enter the seting menu for angle calibration.If it is not accurate, there may
be magnetic field interference nearby,please check again.
