CONTROL PANEL 3 - 20

How to use the control panel

When you operate the Menu buttons (+, -, Set or Back), remember
the following basic steps:
If no control panel operations are performed for 30 seconds, the
LCD automatically returns to READY.
When you press the Set button to choose a setting, an asterisk
appears at the end of the display for a short time. After that, the
display returns to the previous menu level.
After changing the status or a setting, pressing the Back button
before you press the Set button will cause the display to return to
the previous menu level with the original settings unchanged.
There are two ways to input numbers. You can press + or - to
scroll up or down one number at a time, or you can hold down + or
- to scroll faster. The blinking number is the one that you can
change.
