Inspection

To ensure the readiness and optimum working condition of the Welch Allyn AED 10, the
unit should be inspected weekly or monthly, depending on the frequency of its use. The
checks outlined in the operator checklists should be planned according to the inspection
schedule outlined below.
Frequency of Use
Monthly
Infrequently, such as once a year
Also, new pads or other accessories should be checked for compatibility with the Welch
Allyn AED 10 when they are first received.
Note If the Welch Allyn AED 10 is used more than once per month, it is recommended
that authorized service personnel perform a periodic inspection servicing at least
once per year.

Automatic Self-Test

The AED 10 will automatically perform a weekly self-test while in standby mode with a
battery inserted. The AED 10 will also continuously monitor battery level. During weekly
self-test, the following tests are performed: battery, main processor, stuck key, internal
circuitry, ECG acquisition system, and defibrillator. If a failure occurs during weekly self-
test, it will be identified on the display accompanied by an audible notification.
Once the weekly self-test failure occurs, the AED 10 will turn itself on every two hours
providing six audible notifications spaced 30 seconds apart. Powering up the AED 10
using the ON button will reset the hourly notification.
If a LOW BATTERY is detected during the self test for two consecutive weeks, the unit
will wake itself up 30 seconds after the weekly self test executed and provide a single
beep followed by the voice prompt "LOW BATTERY. " The AED 10 will turn itself off and
wake up 30 seconds later to repeat the beep and the "LOW BATTERY" phrase.
The AED 10 will then go to sleep for 18 hours before restarting the beep and voice prompt
cycle listed above. The cycle will repeat for approximately two weeks or until the AED 10
is powered up by the user to address the issue.
After two weeks, the AED 10 will stop waking up to deliver the beep and "LOW
BATTERY" notifications and will revert to the standard weekly self test process where it
will only supply a failure beep and tone at the end of the weekly test.
If the failure was a fatal error other than a low battery, the unit will act the same as
described above, except the two beep and LOW BATTERY notifications will be replaced
by six dual beep cycles, each 30 seconds apart. These six dual beep notifications will be
repeated every 18 hours for approximately two weeks, or until the AED 10 is powered up
by the user to address the issue.
If both a low battery and another fatal error are present during the self test, the user will
get both audible notifications described above.
The user can stop these notifications by powering up the unit and addressing the
problem.
