Using the Avant™ 4000 Digital Pulse Oximetry System
Installing the Battery Pack in the Display Unit
WARNING: The battery pack must be installed at all times while the
device is operating—even when operating on AC power. If it is
necessary to operate the device without batteries, audible
alarms and memory functions may not be available. DO NOT
use the device without batteries when patient safety relies
upon audible alarms.
NOTE: Contact your distributor or NONIN to purchase or replace battery
packs.
NOTE: Reposition the back cover carefully, and tighten the screws
firmly—being careful not to over-tighten.
