LIFEPAK 500 automated external defibrillator Modes of Operation
5-12
Auto Test Modes Page 4 of 4
Extended Auto Test The AED automatically turns on and performs the following Extended Auto Test
on the first Monday morning of the month at 0300 (3:00 a.m.):
■ The standard Daily Auto Test
■ Additional testing of front-end circuitry
■ (LIFEPAK 500 Biphasic AED only): Additional relay testing
The Daily Auto Test includes charging the Energy Storage Capacitor to about
50 joules and discharging it internally (this energy is not available at the patient
cable connector). The Daily Auto Test is not performed if the AED is already on
at 0300 or if the battery is not installed; if the AED ON/OFF key is pressed while
the Daily Auto Test is in progress, the test is halted and the AED is available for
normal operation.
WARNING! (LIFEPAK 500 Monophasic AED with
Operating System Software Version 4.0)
Possible loss of power during patient care. Do not leave an external test
load or patient simulator connected to the AED when not in use. The AED
enters Normal Mode instead of performing a Daily Auto Test if it is
connected to a patient, an external test load, or a patient simulator at the
time of test initialization. The AED will remain on and continue to drain the
battery until it is turned off or until the battery is depleted.
