Most of these devices use a conductive rubber "pill" that is pressed against a set of interdigitated finger traces on a circuit board beneath the keys. These can get dirty OR can have a crack in the circuit board/trace.

The latter is fatal. The dirt you disassemble and clean with a Q tip and 91 or 99% isoprophyl alcohol.

Clean both the "pill" (usuall black) and the place it presses against.

Keep the alcohol off the plastic case.

What to check if Plantronics cordless mic does not work but earpiece works fine

If the party you call cannot hear you, check two things:

1- while on phone with the party, change the configuration dial on the headset base to 1. (We have Nortel phones and it must be on 1 for headset and mic to work with Nortel phone sets.)
2- Push IN on the headset volume control. Pushing IN activates or deactivates to MUTE feature on the headset.

Hope this tip helps you.

On my new Plantronics S12 Headset System, I hear a dial-tone (through the headset) when I press the headset button, but when I remove the phone and begin dialing nothing happens. I also tried a test call...

Unfortunately, the phone does matter. The S12 is designed to work with office style phones where the handset is just the mouthpiece, all other features located on the base. My suggestion is to get a phone of that style (you can find inexpensive ones at Wally world) and connect the headset following the instructions on this link for the Plantronics S12.

Good luck from Headsets Direct!

How to replace battery?

Just put the tip of a pen into the opening at the bottom of the handset that looks like hole. The cover will pop off.

Can not get my plantronics calisto phone to par with the headset or the base

We have two of the Calistro Pros and they will lose contact all the time for no apparent reason. Most of the time when I walk to far away from the handset they will beep and there will be the "OUT OF RANGE" will display. I have found that while sitting next to the phone press the ear piece switch straight in. You will hear a series of tones either getting louder or going from high to low. Wait a few seconds after pressing the ear piece switch and then look at the hand set. the No Headset circle should dissaper. If not depress the earpiece switch and listing for the tones again. Wait again and they will find each other. If this does not help you then I think you have a phone issue. I use my for 8 hours a day and have to do this several times a day. I hope this helps.
