Make an exchange line test call to verify wiring between extensions, main unit and PSTN
exchange lines.
Set the system clock (see page 42).
If an Executive Terminal or Standard Terminal is fitted then it will automatically identify itself
to the system, this will take longer if more than one terminal is connected. Should the
identification fail for any reason then the Line 1 lamp will flash. In this case the terminal may be
logged on manually by dialling the code * 751 ext. #.
