Registration and deregistration
Adding and registering handsets
3. The In USE light on the telephone base turns on. The handset
shows Registering... Please wait. When the registration is
successful, the handset shows HAnDSET X Registered (HAnDSET
represents the handset name, X represents the handset number)
and you hear a confirmation tone. The In USE light turns off. The
handset is now registered with the telephone base.
If the registration fails, the system will automatically try to register
again. If registration fails after the third try, Registration Failed
appears on both screens. The handset shows To register HS, see
manual and the telephone base returns to idle mode. This may
take up to five minutes to occur. Please start again from Step 1.
NOTES:
• You cannot register a handset if any other system handset is in use.
• You can only register one handset to the telephone base at a time.
