and an access
code restrict access, intended
for competent trained service personnel only. The Entr(+-)command is done by
PUSHING MENU AND ESC AT THE SAME TIME (hold down for about 14 seconds).
The access code has eight binary digits; one press at MENU(+) equals 1 and one
press at ESC(-) equals 0. The code value can be changed for your personal choice
from the software UIP 4.3.
Always use the ESC button to return to the DEFAULT mode. Several pushes of the
ESC button may be needed to return to the DEFAULT mode. The
Entr(+-)
push
(MENU & ESC) eventually leads to execution of functions, which causes temporary
or permanently change of any parameter, that affects the system outputs!
