Deregistering the cordless headset without the VCS752
Cordless headsets can also be deregistered using the headset. You can use this
method when you cannot use the deskset for standard deregistration. The VCS752
may be out of range or may have been removed from the system. Check your
headset manual for deregistration instructions applicable to your model.
Cordless accessory registration and deregistration time-out
If the cordless device is registered to another telephone, it must be deregistered rst.
See “Deregistering a cordless headset”.
For security reasons, the registration process on both the phone and the cordless
accessory terminates after the time-out period of two minutes if registration is not
successful.
If the registration process times out on the cordless accessory, the cordless
accessory resets itself. If the registration process times out on the phone, it displays
Registration Failed and returns to Idle mode.
If cordless headset registration fails, the ON/OFF light on the headset ashes twice
every ve seconds. To reset the headset, lift the headset out of its charging base,
place it back in the charger, and try the registration process again.
