Why do I hear beeps in the headset of my Plantronics CS55?
A. On the Plantronics CS55, one beep every 10 seconds is caused by a low battery warning. Recharge the battery by returning it to the base charge cradle for one to three hours until charge light stays lit or stops blinking. Two beeps is an out of range warning. Move closer to the base unit. Three rapid beeps every 15 seconds indicates your mute is on. Press the mute control once to turn it off. When the optional HL10 handset lifter is connected, Three rapid beeps indicate a call is coming into the headset. Press the talk button on the headset to anwer the call.
