Default energy settings
Accuracy at 50
Ω
: ± 3 J or ± 15 % (the higher value is assumed)
SCHILLER's customer service department can change the default energy levels to
the following values:
70 – 90 –120 – 150 – 200 J (adults)
30 – 50 – 70 J (children)
(automatic adaptation when paediatric pads are connected)
Cycle time: rhythm analysis –
