Satellites LED (blue)
•When the receiver is searching satellites, the green
LED flashes once every 5 seconds
•When the receiver has tracked N satellites, the
green LED will flash N times every 5 seconds.
Correction LED
•Indicates whether the receiver is
transmitting/receiving differential data.
•The LED flashes once per second when
As a Base station (orange): successfully
transmitting differential data.
As a Rover station (orange): successfully receiving
differential data from Base station but float.
As a Rover station (green): successfully receiving
differential data from Base station and fix.
Static LED (orange)
If E91 is recording static data:
•If the recording rate is larger than 1 s, the static LED
will flash as the setting rate.
•If the recording rate is less than 1 s, the static LED
will flash twice per every second.
If the memory of E91 is full, the static LED will keep
awake.
If E91 is in APIS mode, the static will keep 3 s awake per
10 s.
Power LED
If E91 has already powered on:
•If the power of internal battery is more than 20%
or the receiver is charging via 7-pin port, the power
LED (green) will keep awake.
