XP Series Personal Gas Detector

In set-up mode, pressing the Up or Down button selects the function and pressing the On/Off button
activates the function, so that the displayed value may be changed. For each value, pressing the Up
button increases the displayed value, pressing the Down button decreases the displayed value, and
pressing the On/Off button sets the displayed value. Once the displayed value has been changed and
accepted, then the new value is stored within the detector. The value can be returned to its previous
value by pressing the Up and Down buttons together, e.g.
Prompt
UP button to increase
On/Off button to accept Up + Down button to cancel
If no button is pressed within 20 seconds or both buttons are pressed together the XP will revert back
to its normal gas monitoring mode.
