Using The Detector's Buttons - Thermo Scientific APEX 100 User Manual

The Display Panel
The display panel allows you to access all the detector's functions.
The Indicator Lights
These give you a quick overview of how the detector is functioning.
• Red—Flashing once indicates an excess product effect; steady indicates a fault.
• Green—Indicates a product is present in the detector's search head.
• Yellow—Indicates a contaminant has been detected in the product.
The Navigation Buttons
These allow you to navigate around the detector's menus and sub-menus. When you
press a navigation button, the display highlights an adjacent function (using a black
background). You access the highlighted function by pressing the Go button. In addition,
the four navigation buttons are used increase or decrease numbers and select characters
and settings in various menus and input screens.
The Go Button
Press the Go button to select or start one of the detector's functions.
The Back Button
Press the Back button to stop one of the detector's functions or to return to the previous
menu screen. Pressing the Back button repeatedly will always take you back to the
detector's Main Menu.

Using the Detector's Buttons

The detector's buttons—unlike those on a cell phone, for example—are not activated by
direct mechanical force. Instead, a sensor below the image of the button on the control
panel detects the movement of your finger to and away from the button's location. As a
result, the best way to activate the button is to lightly tap the button and—the key point
here—immediately move your finger away from the button. For most people, this to-
and-away motion is not intuitive but, with a little practice, you will find this is the best
way to activate the detector's buttons.
