ACTIVATION
To Activate the Pro Plus 2, press and release the Left (Advance) Button.
Upon manual activation, the unit will enter Diagnostic Mode (Fig. 14), displaying all
segments of the LCD as 8's, followed by dashes (- -), then a countdown from 9 to 0.
Diagnostic Mode checks the display and battery voltage to ensure that everything is
within tolerance and functioning properly.
Backup Activation (
only if Water Activation is set ON)
As a backup, the Pro Plus 2 will also automatically activate by water contact. This is
accomplished by bridging the gap between contacts located on the Button stems and
case. The graphic H2O that will be displayed as an indication is described later.
If no dive is made within 2 hours after initial activation, the
unit will automatically deactivate. If the wet contacts are still
bridged, the unit will reactivate and display the H2O
graphic.
WARNING: If the unit is manually activated at eleva-
tions higher than 14,000 feet (4,267 meters), it will
perform a diagnostic check followed by immediate
shutdown.
