Tried unmuting the headset

1. make sure HS-905BT is off (hold Power till the blue light goes off, you hear descending sequence of tones)

2. hold Power to turn on (ascending tones, blue LED on) + KEEP holding Power till the blue LED flashes twice and you hear a double-beep. Device is ready for pairing.

Hello.

Make sure your headset is not Low-Bat and you are not far away from your mobile phone then try it again.

The three beeps usually indicate low talk time. If you have tried turning off and on your headset and still have the annoying beeps, then there is a problem with the device. You'll need to contact your retailer or Plantronics (800-544-4660 x5538) for warranty replacement. If it's out of warranty, check out our website Headsets Direct for the latest in Bluetooth headsets.

Good luck from Headsets Direct!

Try to unmute the headset. This may be your problem. The mute function is enabled through the volume buttons. Simply tap both volume buttons at the same time until you hear a mute tone. The mute tone when unmuting the call will be a descending tone. When you tap both volume buttons, if you hear a descending tone you have just disabled the mute function and your problem is solved. If the mute tone is ascending tones you have just enable the mute function and this was not the issue. If this is the case consult your user manual or contact Motorola for trouble shooting.

Could be that the headset has been muted by accident. To unmute, tap both volume buttons at the same time until you hear a tone or kind of beep.

sounds like the non replaceable battery is bad get another headset cheap at www.n1wireless.com

a short beep normally indicates that your phones network signal is low or absent, so you are aware that you are in a low signal area without looking at your phone, or two short peeps normally means the headset needs charging.

Press both buttons at once to unmute the headset - you should hear two beeps, in ascending tone.
