Replacement Battery for Plantronics CS50

Product Code: 64399-01

If you have had your CS50 for less than a year and you are having problems that lead you to believe your battery has gone bad, the system probably just needs to be re-synchronized.

If your CS50 had been working great and then suddenly began exhibiting extremely loud static, or if your HL10 handset lifter suddenly stopped operating properly, then your system most likely needs to be re-synchronized. Please follow these simple instructions and your system will be as good as new:

STEP 1: SYSTEM RESET
A.) Press both the talk button and the mute control button on the headset simultaneously for 10 seconds. When the talk indicator light on the headset blinks, release both buttons.

B.) Press the talk button again and then release.

C.) Disconnect the AC power adapter from the AC power outlet and leave it unplugged for 10 seconds, then reconnect.

The system reset operation is now complete. If your CS50 problem has now been resolved, there's no need to go on to Step 2 below. If your CS50 problem still exists, please continue to the Subscription Reset operation below.

STEP 2: SUBSCRIPTION RESET

A.) Place the headset into the base charging cradle and be sure that it is pressed down and seated all the way in the charger.

B.) Press and hold both of the talk volume fine tune buttons on the back of the base (the buttons marked "+" and "-") simultaneously for a minimum of 10 seconds. The power indicator light on the base will flash red and you can release the buttons.

C.) Next, push and hold the mute control button on the headset for a minimum of 5 seconds. The talk indicator on the headset will light up green.

Successful re-subscription is indicated when the power indicator on the base is fully illuminated and the talk indicator light on the headset is off.

D.) To complete the process, disconnect the AC power adapter from the AC power outlet and leave it unplugged for 10 seconds, then reconnect.
