Some examples and use cases from the internet:

• where audible warning devices receive direct current that must be supplied by an electrical generator of the type normally used with this type of device.
• The device receives telemetric signals containing traffic information using a traffic message channel through FM radio broadcast band.

• For the devices receiving a printing order from a computer, a message should be formulated by the manufacturer and displayed on the computer screen of the user when the default setting is changed into one
• in the case of audible warning devices receiving direct current a test voltage of 6,5, 13 or 26 volts, measured at the output side of the eletricity source and corresponding to a nominal voltage of 6, 12 or 24 volts respectively;
• If a rectified current is used for the test on an audible warning device receiving direct current, the unsmoothed component of the voltage at its terminals, measured from peak to peak during operation of the warning devices, must not exceed 0,1 volts.
• The resistance of the electrical conductor for audible warning devices receiving direct current, including the resistance of the terminals and contacts, must lie as closely as possible to:
• side printing.
