Important Safety Instructions

When using your video equipment, basic safety precautions

should always be followed, including the following:

1. Read and understand all instructions before using.

2. Position the cord so that it will not be tripped over, pulled,

or contact hot surfaces.

3. If an extension cord is necessary, a cord with a current rating

at least equal to that of the appliance should be used. Cords

rated for less amperage than the appliance may overheat.

4. To reduce the risk of electric shock, do not disassemble this

appliance. Contact an authorized service dealer when repair

work is required. Incorrect reassembly can cause electric

shock when the appliance is used subsequently.

5. The use of an accessory attachment not recommended by

the manufacturer may cause a risk of ire, electric shock,

or injury to persons.
