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 re.

Incorrectly inserted batteries may destroy the device or the batteries. Ensure that proper polarity is observed when inserting bat‐
teries.
NOTICE!
