IMPORTANTSAFETYINSTRUCTIONS
When using the Slide Scanner, basic safety precautions should always be followed including the
following:
•Readand understand all instructions before using.
•Position the cord so that it will not be tripped over, pulled, or contact hot or sharp surfaces.
•If an extension cord is necessary, a UL recognized grounded cord with a rating at least
equal to that of the slide scanner should be used. Extension cords rated for less amperage
may overheat. Connect the slide scanner to a grounded outlet.
•Always turn the host computerOFF and then the slide scannerOFF before unplugging.
•Always unplug the slide scanner from the electrical outlet before cleaning and servicing and
when not in use. Never pull the cord from the outlet. Grasp and pull the plug from the outlet
to disconnect.
•Do not disassemble the slide scanner, but take it to a qualified service person when service
or repair work is required. Incorrect assembly can cause electrical shock when the slide
scannerisusedsubsequently.
