Diagnostics
A number of diagnostics tests can be performed to test the hard-
ware and software of the optiPoint 300 basic.
Display test
When you test the display, all of the symbols and display seg-
ments should show on the display.
Keyboard test
This test allows you to check the keys of your optiPoint 300 basic
unit one by one: as you press a key, a click will sound to indicate
that it has registered, but without performing the normal function
of the key.
