Q: I’m using a Plantronics CS50 wireless headset and handset lifter.  I no longer get the beep notification for incoming calls.  Is something wrong with my CS50?

A: It is the handset lifter that actually picks up the ring tone from the telephone, and not the CS50 itself.  The first thing that you want to do is make sure that the ring tone or ring volume didn’t change on the phone, because this could throw off how the lifter ”hears” it.  Also, I’m not sure which lifter your user has.. if it’s the larger HL1 (this one has a base that the phone sits on), there is a sensitivity adjustment on the back of the lifter.  If is the smaller HL10 which sticks onto the phone (and should be positioned over the speaker grill where the ring tone comes out of the phone), the internal mic may have stopped working and that could be why it doesn’t hear the ring anymore.  If you have the HL10, you can try using a ring detector cable, this is a little accessory that should have come with your lifter (it looks like a wire with a small speaker on the end of it with double-sided tape).  Plug this into the back of the HL10 (there are 2 jacks back there but it will only fit in one, you may need to remove the rubber plug), then stick the little speaker over the speaker grill on the telephone.  If this doesn’t work, you may need to replace the lifter.  Here is a link below with a picture to take a look at the ring detector.
