28 GSR2700 IS Operations Manual
Chapter 3 Display Panel Operations
Table 9 summarizes the values indicated by each LED for internal
and external batteries, and charging status.
When the internal batteries have full charge, the top LED (green)
is illuminated. The bottom LED (red) is illuminated when you
have less than one hour of battery power remaining.
When the receiver is off and the batteries are charging, the top
LED blinks; the LED stops blinking when charging is complete.
3.3.2 Satellite tracking gauge
The satellite tracking gauge displays the number of
satellites currently being tracked by the receiver. If the
current position of the receiver is being held fixed,
consistent with RTK base operation, the currently
illuminated LED will blink.
For a satellite to be counted as used, it must have a healthy signal
and be above the elevation mask, and the receiver must have
achieved lock (both code and carrier).
