De-Register All Handsets - VTech MI6889 User Manual

Registration
After a while the handset will emit series of tones, the newly registered handset will be assigned the
lowest extension number not previously assigned to another system handset (1-4) when successfully
registered. Repeat steps 1 and  if handset does not successfully register to the telephone base
