DefiSign Life AED

2.4 Function

Status LED

Service

LEDs

Immediately  after  a  battery  has  been  inserted,  the 

DefiSign Life AED

®

  performs  a 

test of the device and battery. If this test is completed successfully, the green status 
LED is blink-ing and all service status LEDs are off, showing that the device has not 
detected an error.

If a problem is detected during this test:

• an acoustic alarm is issued,
• the status LED stops blinking
• additional information are given by the service LEDs

Fig. 2.1

LED indicator

• If an alarm is in progress (visual and/or acoustic), the battery autonomy is reduced.
• In addition, the device performs a daily or weekly self-test (this setting must only 

be configured by service personnel authorised by Schiller)

• An alarm (visual and/or acoustic) can only be reset by removing and reinserting the 

battery.

• For the alarm details, refer to chapter 

6.5.1 Error messages.
