ACTIVATION
To Activate the XR2, press and release the Advance (Front) button.
The XR2 will also automatically activate by water contact, unless
Wet Activation is set OFF (a user setting). This is accomplished
by bridging the gap between contacts located on the stems of the
control buttons and back of the module. The graphic H2O will be
displayed as an indication. If the Water Activation feature (a user
setting) is set OFF, the XR2 will only activate by push button and
only if shallower than 4 feet (1.2 meters) depth.
Upon manual activation, the Backlight will come ON and the
unit will enter Diagnostic Mode (Fig. 15), displaying all seg-
ments of the LCD, then dashes, then a countdown from 9 to 0.
Diagnostic Mode checks the display and battery voltage to en-
sure that everything is within tolerance and functioning prop-
erly.
When the Advance (Front) button is held depressed when the
Diagnostic countdown reaches 00, an External Access request is
initiated. A Serial Number screen appears displaying the units
Serial Number and firmware code Revision Number as long as
the button is held depressed (Fig. 16). Upon releasing the but-
ton, the unit shuts Off.
