Hi, I have the GN9120 and they are getting ve...

Hello Jennifer,

I do not own a GN9120, or anything similar (I have an old bluetooth earbud for a cellphone), but it sounds like a typical exhausted battery issue.

Batteries get old and sometimes do not charge to full capacity. According to the pdf manual from Jabra, the headset will beep every 20 seconds if the battery is low.

Another idea is maybe they are drifting off-frequency, either the adjustment got knocked off (if there is a physical adjustment inside), or the capacitor or other component values have changed to cause them to transmit off-frequency. I am surprised there is no sort of squelch on the base unit like they have in wireless microphones used on-stage.

Also check the phone cable between the base unit and any other phone cables.

My last thought is check the power supply for the base unit, sometimes they fail and output too low of a Voltage or start becoming noisy with power line noise.

I hope you figure it out! :-)

I am thankfully not near the fires here in California...

My GN9120 does not connect ...

I solved this over the weekend: I found out, that the GN9120 comes with slightly differing battery sizes. I had to push the contacts deeper inside the housing so they got in touch with the new battery again. I used a very small flat screwdriver to achieve that. You have to be careful not to destroy anything surrounding.
This was an easy solution to a stuoid problem, but the contacts are barely visible in the inside of the GN9120 so i needs to have the idea to search for that as the source of trouble,

Plantronics GN9120 microphone is too quiet for listener

I've had this same probelm and after much pressing of buttons eventualy fixed it by reading the manual... :s

Last page page of Quick Set-Up Guide under "Transmit volume adjustment":

1.) Make call to another phone user to assist.
2.) Press + and - on the headset at the same time.
3.) Adjust volume by pressing either - and +.
4.) Confirm volume with helper.
5.) Wait for 10secs and the settings will store.
