How to fix Symmetricom Receiver if power LED is off?
If the power LED on your Symmetricom Receiver doesn't light up when you turn it on, the issue might be with the power supply. First, check the fuses in the power entry module. Also, inspect the power wiring connections to ensure they are properly connected.
What to do if Symmetricom ET6000 does not track satellites and shows 'ANT. UNDERCURRENT' error?
If your Symmetricom Receiver displays an 'ANT. UNDERCURRENT' error and isn't tracking satellites, it could be due to antenna issues. The antenna or preamp might have failed. Alternatively, the antenna cable could be open or shorted, specifically with the center conductor touching the shield.
Why is tracking LED not illuminating on Symmetricom Receiver?
If the tracking LED on your Symmetricom Receiver isn't lighting up, there could be several reasons. The antenna or preamp might be defective. Another possibility is that the cable or connections between the antenna/preamp and the unit are open or have intermittent issues. Also, the OnCore GPS Module (55182) could be defective.
How to perform a cold reset on Symmetricom ET6000 Receiver?
