Spectra Precision Survey Pro v4.9 - Manual (Page 29)

The General tab enables you to change general settings on the receiver.
Every receiver has the option to change the elevation cutoff angle and the option to set the receiver to Off Mode.
Models which have special settings available are described below.
Elevation cutoff: Keep receiver from using satellites in its position calculation that are below the given angle. The
elevation angle is given in degrees above the horizon and can be anywhere from 0 degrees (use all satellites) to 90
degrees (use no satellites).
[Set Rx. to OFF Mode]: Tap to set your receiver to Off mode. This is where your receiver does not output or accept
base corrections, effectively stopping RTK operations. This may be necessary in order to configure the radio.

Confidence Level: is where you set the confidence level for ambiguity fixing. The values here are the statistical
