So, both handsets are Mark I's
If you have followed the previous advice by:-
- Pressing the button on the base and hold it for about 2 seconds until the indicator light on the base flashes.
- Press the phone symbol and it should say REGISTER BASE ? you then press OK
If the above does NOT work then it means that your purchased handset is still registered to the previous owners base and you will need to un-register it first.
To un-register the phone you need to:-
- Go to the MENU item called HANDSET/BASE by pressing 7
- Turn wheel to find REMOVE BASE then press OK
- Turn the wheel to select the base you wish to remove if it was registered with more than one base then press OK
Once you have de-registered the handset from all bases you can then go base and register it with your base.
If you get a request to add a pin code then use "0000" but due to a software bug this prompt will also occur if you have 6 handsets already registered with your base.
