Resetting GPS
To reset the GPS, press the Reset submenu key. The green GPS icon shows a red cross mark when satellite tracking is lost after tracking four or more satellites. The GPS latitude and longitude are saved in the instrument memory until the Spectrum Master is turned off or until GPS is turned off by using the GPS On/Off key.
