The therapy device Soleo
line
has numerous hardware and software safety features for the safety of patients and
users.
Dangers that may arise from undefined control conditions or functional errors in the device are prevented by various
safety circuits.
A temperature monitoring function prevents overheating.
If the device malfunctions, the software stops the therapy and set all modules to a safe status.
The fault is shown on
the display as an error status.
The device runs a self-test when switched on to check all-important components. The 5V operating voltage is also
checked. If a fault occurs, a fault display will be shown. The device can only be switched off in this case.
If the processor operating voltage is not 5 V, it will remain on reset continuously. The device cannot be reactivated.
The processor functions are monitored by a watchdog device. It monitors the program operation and initiates a
processor reset in the event of malfunction (such as an endless loop).

Do not touch modules or parts in the device when working on an open device with the power cable plugged in.
Electrical cables and wires may have a voltage up to 120V/ 240 V. Unplug power cable before opening and
closing the device.
