To convert 110 volts to 220 volts:

Make sure the appliance to be plugged in uses fewer watts than the transformer's rating.

Insert the voltage tap plug (located on the rear of the transformer) into the pair of holes marked "110".

Plug the transformer's power cord into a source of 110 volts.

220 volts will be available at the front panel outlet marked "220" volts when the power switch is turned on.

To convert 220 volts to 110 volts:

Make sure the appliance to be plugged in uses fewer watts than the transformer's rating.

Insert the voltage tap plug (located on the rear of the transformer) into the pair of holes corresponding to the local voltage standard . Check carefully to be sure no error has been made.

（The power of our transformer must be 2.5 times larger than the buyer's appliance to be used normally.）
