To convert 220 volts to 110 volts: 1. Make sure the appliance to be plugged in uses fewer watts than the transformer's rating(80%). 2. 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.   Specification Model No.: DT-1000VA Shell Material: Iron Protection Mode: Overload Protector Rated Capacity: 1KVA Rated Power: 800W Output Voltage: 110V 220V Product Size: 15.3*23*19.3cm/ 6.02*9.06*7.6in   Package Included 1* Transformer 1* Power Cord 1* English Instruction Manual   Notes 1.To prevent damage and possible fire hazards, the fuse should be replaced with a slow fuse (MDL) of the same amperage rating as the original fuse. If the fuse continues to blow, the transformer and/or the appliances connected to it may require service. 2.Please do not connect appliances that exceed the maximum power rating of the transformer to it.
