600# Direct Access - Direct access to the parameters
This is a main menu that gives you direct accesss to the settings and display values (see section
10.3 ”Direct Access (to the parameters)” (page 69)).
10.2 Changing Parameters
Using the up and down arrow buttons, you navigate through a selected menu to view or change a
parameter, for example. When the relevant parameter appears on the display, you can read its
present value.
An arrow next to the value indicates that the parameter can be changed.
If you press <ENTER>, the arrow begins to blink, and you can use the up and down arrow buttons to
change the value of the parameter.
As soon as the desired value appears on the display, press <ENTER> to save the new value.
Then select Y(es) or N(o) by pressing the up/down arrow buttons to accept or reject the changes.
Finally press <ENTER> again in order to finish the process and continue with other modifications.

standby mode or require a different password level.
