If an AC source is present, the oximeter will draw power from it first. While the oximeter is
operating from an AC source, the External Power Indicator ( ) will illuminate.
If there is enough power, the WW1090 Lithium-Ion (LI+) rechargeable battery pack will also
charge, if installed. The battery charge indicator ( ) will display segments showing the charge
level. As the battery charges, more green segments will light, until all four are lit.
nOTe: The AC Power supply does nOT charge “AA” (lR6) alkaline batteries.
If no external power source is available, the oximeter will draw battery power. When the battery
charge is low enough, the Battery Indicator shows one yellow segment. When the battery has less
than approximately 30 minutes of charge left, that segment will flash, and the low battery alert
will sound. See the Low Battery Signal section in Chapter 6: Alarms .
If no AC source is available, the oximeter will operate from an external USB source only when
attached to a WW1089 USB Interface Cable and energized USB connection. In this case, the
external power indicator lights. If enough power is available, the optional WW1090 Lithium-Ion
(Li+) rechargeable battery pack will trickle charge.
