2.3 SELF-TEST DuRING START-uP (CRT/HNA/HWT)
A series of tests is accomplished after the machine has been turned on. If a test is not successful:
a series of audible signals is given, or
•
an error code is read out.
•
On HNA/HWT or CRT models, a three-tone signal is given once, if the machine is operative.
In case there is a functional error it must be acknowledged by pressing the STOP or ESC key and there is no
three-tone signal.
