8. Magnetic switch activation 
Series 3000 MkII uses magnetic switches to enable non-intrusive operation. To activate a magnetic switch, 
hold the magnet up to the glass window directly over the magnetic switch area. The switch is activated 
when you then remove the magnet. For example: to put the detector into Menu Mode hold the magnet 
over the ‘’ magnetic switch for 5 seconds, and then remove the magnet. The detector enters menu 
mode on removal of the magnet (not automatically after 5 seconds). Similarly, when changing values or 
navigating in a menu using the ‘’ magnetic switches, hold the magnet up to the glass window directly 
over the switch momentarily, and then remove to activate the switch. In some menus where the displayed 
value can be changed the magnet can be held over the switch and the numeral on the display will scroll 
through the available values. Remove the magnet when the required value is displayed. 
For the purposes of this manual, the instruction to use ‘’, ‘’ or ‘’, means to activate the relevant 
magnetic switch as described above.
