IMPORTANT SAFETY INSTRUCTIONS
When using your Micromatic II, basic safety precautions should
always be followed, including the following:
1. Read and understand all instructions before using.
2. Close supervision is necessary when any projector is used by or
near children. Do not leave projector unattended while in use.
3. Care must be taken as bums can occur from touching hot parts.
4. Do not operate projector with a damaged cord or if the projector
has been dropped or damaged - until it has been examined by
a qualified serviceman.
5. Position the cord so that it will not be tripped over, be pulled or
contact hot surfaces.
6. If an extension cord is necessary, a cord with a current rating at
least equal to that of the projector should be used. Cords rated
for less amperage than the projector may overheat.
7. Always unplug projector from electrical outlet before cleaning
and servicing and when not in use. Never yank cord to pull
plug from outlet. Grasp plug and pull to disconnect.
8. Let projector cool completely before putting away. Loop cord
loosely around projector when storing,
9. To protect against the risk of electric shock, do not immerse this
projector in water or other liquids.
10. To avoid the risk of electric shock, do not disassemble this
projector, but take it to a qualified serviceman when some
service or repair work is required. Incorrect reassembly can
cause electric shock when the projector is used subsequently.
11. The use of accessory attachment not recommended by the
manufacturer may cause a risk of fire, electric shock or injury
to persons.
12. Connect this projector to a grounded outlet.
13. Disconnect this unit from its source of supply before replacing
the projection lamp.
Additional lamp safeguards: never handle lamps with bare fingers;
periodically inspect lamps, when they’re turned off, for signs of
blistering or blackening; insure proper action of the cooling system;
turn off the projector immediately if the image becomes abnormally
dim; never operate a projector with the lamp housing open; and make
sure that the lamp itself is properly seated.
