Troubleshooting LED conditions

The receiver has a simple display panel with LEDs to indicate the current status of the receiver. If you need more detailed information about what the receiver is doing, use a Trimble controller or access all configuration settings by connecting the receiver to your smart phone or laptop computer via Configuring the receiver using Wi-Fi and the web interface.

This section describes how the LED lights are used on the receiver to indicate current status. An LED that is flashing quickly indicates a condition that may require attention, and an unlit LED indicates that no operation is occurring. This section describes some LED conditions, possible causes, and how to solve them.

The SV Tracking LED is lit solidly and the Logging/Memory LED is flashing slowly

Possible cause

Solution

The receiver is in Monitor mode, ready for new firmware to be loaded or new options to be added.

Turn on or turn off the receiver. If that does not fix the problem, load the latest version of the firmware using Trimble Installation Manager. See Upgrading the receiver firmware.

The SV Tracking LED is not flashing

Possible cause

Solution

The receiver is tracking fewer than four satellites.

Wait until the SV Tracking LED is flashing slowly.
