The Lamp Change option is a help when replacing the lamp.
To access this option a PIN code must be entered. The default code is '1234'.
There is an option to reset a lamp counter so the system can warn you when there
are 500 hours left of the expected lamp lifetime.
Here is also so you can change the type of lamp that is installed in the instrument,
either the normal 35 W lamp or the 50 W long-life lamp.
