4.2 Navigating main menu

Navigation through the menu options is done by activating menu button 1 or 2. The same function is provided using magnet to select Reed switch 1 (indicated by printed magnet in the 8’ o clock position on the face plate) or Reed switch 2 (indicated by printed magnet in the 6’ o clock position on the face plate).

1.Enter the main menu, either intrusive or non-intrusive (using the magnet), by selecting/activating any button then select “yes” by using switch 1.

2.The message “Calibrate Sensor?” will be displayed.

3.Activate up-down buttons (switch 1) or (switch 2) to scroll/navigate through main menu options.

4.Select/activate the enter key (switch 3) to display sub menu. See

5.Figure 16 and Figure 17.

6.To exit the main menu, continue using the navigation keys (up-down keys) and select “Exit” with enter key at each menu stage (sub menu and main menu).

7.The main menu will be exited automatically if no option is selected; it takes 50 seconds to exit to each of the previous options or stage entered. If left untouched, this continues until the main menu is fully exited.
