With all application that require to connect an exter-

nal source to the device, especially if the source is a

battery, attach an extra warning sign onto the device

which instructs the user to be extra careful, watching

the polarity. As an additional measure include fuses in

line with the DC cables which could attenuate or even

prevent damage to the device.
