Testing And Replacing Battery - AirSep ImPulse Elite Patient Manual

Testing and Replacing Battery

ImPulse Elite requires just one 1.5 volt "D" size alkaline battery (Energizer
recommended) for full operation. Battery life is dependent upon the predeter-
mined unit settings, your breathing rate, and the length of daily ambulation time.
Most patients experience 10–18 months of battery life. AirSep strongly recom-
mends that you maintain a spare battery in your carrying case for replacement
in this unit as necessary.
To install or replace the battery, follow the steps below:
1. Make sure the ON/OFF power switch is set to the OFF position. (It
is not necessary to disconnect the cannula or remove the ImPulse
Elite from the cylinder, although you may find it easier to replace the
battery within the battery compartment door if the unit is first
removed from the cylinder.)
2. If the unit is not connected to the
cylinder, simply hold the unit with one
hand while you press in and lift up on
the battery compartment latch with your
other hand. (Figure 7).
If the unit is connected to the cylinder,
steady the unit by grasping the
neck of the cylinder just below the
unit with one hand while you press
in and lift up on the battery
compartment latch with your other
hand (Figure 8).
3. Insert a fully charged battery into
the inside door of the battery
compartment. Make sure
the battery is properly
positioned to match the
correct positive and
negative polarity markings
(Figure 9).
