Parameter Modification Mode

The Parameter Modification mode is accessed by pressing the CHANGE key when an
adjustable parameter is displayed. In the Main Menu, a password is then requested; in the
Extended Menu, a password is requested only for parameters requiring password No. 2
(because password No. 1 has already been entered to access the Extended Menu). For
details on passwords, see Section 4.4 on page 4-9.
The Parameter Modification mode is indicated with a colon displayed on the bottom line,
at the left of the numerical value or choice to being modified. The value of the parameter
can then be changed using the UP and DOWN keys; the modification is validated with
ENTER.

• Short power-up (power-off shorter than five minutes): See Section 4.2.5.2 on page 4-7.
