Encryption check boxes on the My Bluetooth Device screen
correspond with the security settings of the remote device.

Surveying with the GRS-1
Using Topcon Receiver Utility
(TRU)
The GRS-1 can be used in many surveying situations. From GIS
surveying to data collection on a construction jobsite, the GRS-1
provides an integrated solution for all your needs.
Simple surveying (data collection) with the GRS-1 can be handled
with the on-board TRU software. Other surveys may require an
external GPS antenna and/or a Beacon receiver to acquire GPS
signals or correction data for better position accuracy.
