Deregistering a cordless headset
You must deregister a cordless headset from its original deskset before you can 

register it to a different deskset.

To deregister a cordless headset:
1.  When the phone to which the headset is registered is idle, press 

Menu.

2.  Press q to highlight 

User Settings, and then press SELECT.

3.  Press q to highlight 

DECT Headset, and then press SELECT. 

The DECT headset menu appears.

4.  Press q to highlight 

Deregister, and then press 

Select

 .

The deskset screen displays 

DECT headset is deregistered. The cordless 

headset ON/OFF light flashes twice every five seconds to indicate it is not 

registered.

The DECT headset menu appears.

Deregistering the cordless headset without the deskset
Cordless headsets can also be deregistered using the headset. You can use 

this method when you cannot use the deskset for standard deregistration. The 

deskset may be out of range or may have been removed from the system. 
To deregister a VSP505 headset, on the headset, press

Cordless accessory registration and deregistration time-out
If the cordless device is registered to another deskset or telephone, it must be 

deregistered first. See “Deregistering a cordless headset”.
For security reasons, the registration process on both the deskset 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 deskset, it 

displays 

Registration Failed and returns to Idle mode.

If cordless headset registration fails, the ON/OFF light on the headset flashes 

twice every five 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.
