■ CAUTION
1) PLEASE DON`T USE AS A CAR BATTERY CHARGER.
2) Use only in a well ventilated place.
3) Connect the AC plug directly to an AC wall socket.
4) Connect the chassis of the unit to the ground earth.
5) At high internal temperatures, the protecttion circuit will limit the output current.
6) Due to the presence of large magnetic field, please ensure that the output cable of
the SS-330W is kept as far away from your antenna connecting cable as possible.
7) Be sure to use at least 5.5mm diameter wire.
