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.
