2.1.4 None option
The differential type selection NONE causes the receiver to operate without differential inputs,
known as Autonomous mode. This option will not display a menu specific to the option, but will
instead jump to the GPS/Position menu.
2.1.5 AUTO menu (e-Dif)
This single tab menu contains options to configure the receiver for e-Dif operation. An error will
display in the TMNL window if e-Dif is not subscribed.

The receiver can be subscribed using the terminal mode with commands described in the
receiver’s manual using codes supplied when the option is purchased. Contact your dealer or
Hemisphere GPS’ sales team for additional information on purchasing an e-Dif subscription.
For receivers with valid subscriptions (subscription will be shown in the TMNL window), this
menu allows the user to initialize based on the multiple run, a known reference point, entered in
the boxes labeled “Latitude,” “Longitude,” and “Height” to set the latitude, longitude, and height
of a reference position or single run. Please refer to receiver user manual for more details on
which option is appropriate to your application.
