The GS-900 Radio Kit has onboard LED lights that can assist with troubleshooting in the event of a malfunction.

LEDs 1, 2, and 3 are on a small, raised circuit board mounted on the main circuit board. LED 4 is on the main circuit board.
Table 2 GS-900 LED Definitions

1 CD Steady Green Steady Red Off
2 TX Off Off Off
3 CTS Steady Red Blinking Red Off
4 Power/Data Green + Blinks Orange Steady Green Off
Normal Operation
During normal operation LED #4 should be steady green and blink orange about once every second. If LED #4 is steady green
but not blinking orange, it means that the unit is powered up but is not communicating with the Base Station. If the unit is not
communicating with the Base Station, check the channel number of both the GS-900 radio and the radio modem on the Base
Station which should be the same number. Refer to your GeoSteer user manual and Base Station user manual for instructions
on how to verify and, if necessary, change the channel number.
