20 Most Recent GN Netcom Remote Handset Lifter GN-1000RHL Wireless Headset Questions & Answers

I think I just fixed the same problem on mine...
My phone has a headset button. It took a couple tries - but 2nd attempt it worked & I see no more flashing red.
I pushed my speakerphone button on the phone, then hit the lifter button on my headset...then hit the sensor button...and voila!

I had a 9120 for years, great headset. Change the compatibility wheel and levels on the unit per the instruction book link below. https://www.jabra.com/_/media/Product-Documentation/Jabra-GN9120-Series/User-Manuals/User_Manual_Jabra_GN9120-GN9125_EN.pdf

If you haven't already tried this, disconnect the base unit from the computer and then see if the problem continues. If it does, there is likely a fault in the electronic switching in the base unit. If the problem doesn't continue, then it could be an intermittent switch on the base unit. You could try pressing and releasing the computer switch on the base unit multiple times. Maybe even lightly pry it up with your fingernail to make sure it's not stuck down. From my understanding any phone connection will override computer audio, so while on a phone call even if you computer beeps, it should not switch to computer audio. Hopefully this will narrow down the issue.

Many reasons that could be happening. Could need re pairingwith docking station, might need to play with the compatibility dial.

I found the manual!

Wiring a fridge thermostat typically involves connecting the thermostat to the power source and the compressor. Here's a general guide for wiring a 3-pin thermostat:

1. Identify the Pins: The thermostat will typically have three pins labeled 4, 6, and 3.
2. Connect the Power Source: Pin 4 is usually the common (C) terminal, which connects to the power source. This could be the live wire from your electrical supply.
3. Connect the Compressor: Pin 6 is often the normally open (NO) terminal, which connects to the compressor. This allows power to flow to the compressor when the temperature rises above the set threshold.
4. Ground Connection: Pin 3 is commonly the ground (GND) terminal. This should be connected to the ground wire for safety purposes.

I recommend RadioReference.com, they have detailed lists from all over the United States. In addition to frequency lists, they also include live audio, HAM radio lists, licensing information and a lot more.
