2-6 LIFEPAK 500 Automated External Defibrillator Operating Instructions
Getting Ready
Low Battery Detection
Whenever the LIFEPAK 500 AED is turned on after it has been off for at least 60 seconds, it takes
about 10 seconds to complete a self-test and to indicate a low or replace battery condition.
The AED monitors the battery power level and indicates when the battery should be replaced:
When the battery power is too low, the AED will automatically turn off. The service and battery
indicators appear on the Readiness Display.
If the AED detects a low or replace battery condition during an auto test while it is not in use, audible
beeps and the REPLACE BATTERY voice prompt will repeat every 20 minutes until the battery is
replaced or battery power becomes too low to power the AED.
SETTING THE CLOCK
You may set the clock at any time except during the interval between patient care and data transfer to a
computer or printer. Setting the clock during this interval will interfere with proper time synchronization.
To change the date and time:
1 Turn on the AED. (Be sure the AED has been off for at least 60 seconds and that nothing is
connected to the AED.)
2 Press and hold the
! or " button for approximately three seconds until the AED displays the date
and time setting:
A value blinking on and off indicates that the value can be changed. The day, month, year, hour, and
minutes values can be increased. The seconds value can be reset to zero.
3 To set the hour:
• Press the
! button to increase the value.
• Press the
" button to advance to the next field.
4 To set the minutes:
• Press the
! button to increase the value.
• Press the
" button to advance to the next field.
5 To reset the seconds value to zero:
• Press the
! button once.
Note: If the seconds value is less than 30 when reset, the minutes value stays the same. If the
seconds value is greater than 30 seconds when reset, the minutes value increases by one.
• Press the
" button to advance to the next field.
6 Repeat Step 3 as needed to set the day, month, and year.
7 After the date and time are set, press
ON/OFF to turn off the AED.
Indicator illuminates on the device key panel and appears on the Readiness Display and
the
LOW BATTERY message displays on the LCD; battery is low.
Indicator flashes on and off on the device key panel, the REPLACE BATTERY message
displays, and a voice prompt sounds; battery is low and should be replaced immediately.
Note: The Readiness Display battery indicator does not flash.
