NOTICE!
External power supply
The device is powered by an external power supply. Before connecting
the external power supply, ensure that the input voltage (AC outlet)
matches the voltage rating of the device and that the AC outlet is pro‐
tected by a residual current circuit breaker. Failure to do so could result
in damage to the device and possibly the user.
Unplug the external power supply before electrical storms occur and
when the device is unused for long periods of time to reduce the risk of
electric shock or fire.
