2. Record the antenna height, points name, and start time in the field notes.
Step 4: Collect Data (for Base and Rover)
1. Turn on the receiver. The STAT (status) light
(LED) initially blinks red.

Surveying
2. Once the receiver has locked on to one or more satellites, the STAT light blinks green for GPS satellites and orange for GLONASS satellites. A short red blink indicates that the receiver has not solved a position.
3. Once the short red blink is gone, the receiver has a position and surveying can begin; wait for green and orange lights before beginning data collection.
This ensures that the receiver has the correct date and time, and is locked on to enough satellites to ensure good quality data.
The process of locking on to satellites normally takes less than one minute. In a new area, under heavy tree canopy, or after resetting the receiver, it may take several minutes.
4. To begin collecting data, press and hold the
FUNCTION key (for more than one second and less than five seconds).
5. Release the FUNCTION key when the REC
(recording) LED turns green. This indicates that a file has opened and data collection has started. The
REC LED blinks each time data is saved to the internal memory.
6. When finished, press and hold the FUNCTION key until the REC LED light goes out.
