7. Engineer code and lock menu
Engineer
This section is used to programme the dialler’s engineer code and to enable “Engineers lock”.
7.1. Change the dialler code
Dialler code
Enter your new engineer code. This code must be entered to access the dialler menu. It is important
to safe-guard this code because if you change and loose the code, you can only return the dialler to
factory settings (providing menu 7.2 is set at off!) and are unable to recover previously programmed
parameters.
This code is set to 7812 as standard.
7.2. Switch the dialler engineer lock on or off
Digi Eng Lock Off
Switches the engineer lock for the dialler 'On' or 'Off'. You cannot now return the dialler to standard
factory default settings unless this option is 'Off'.
