2 Registering the handset
For the handset to interact with the base
station it must be registered with it.
To register a handset
A handset can be registered to the base station
only if the handset security code on the
handset matches the code on the base station.
The base station code is preset to 0000. If this
has not been changed, you can register the
handset using the ‘simple method’. If it has
been changed you will need to use the
‘customised method’. You will also need to use
the ‘customised method’ if you wish to register
the handset with more than one base station.

method’ of registration in conjunction with the
