Important Safety Instructions
When using the camera, always follow these basic safety precautions:
• Read and understand all instructions before setting up and using the system.
• Close supervision is necessary when any appliance is used by or near
children. Do not leave the camera unattended while in use.
• Do not operate the camera with a damaged cord, or when it has been
dropped or damaged, until it has been examined by a qualified service
person.
• Position the cord so that it will not be tripped over, pulled, or in contact with
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 camera should be used.
• Always turn the camera OFF before unplugging.
• Always unplug the camera from the electrical outlet when not in use, and
before cleaning and servicing. Never pull the cord from the outlet. Grasp
and pull the cord from the outlet to disconnect.
• To reduce the risk of electrical shock, do not immerse the camera in water or
other liquids and do not operate outdoors in inclement weather.
CAUTION
The film used by this camera contains a caustic jelly that is safely
packed inside the film pack. If you should accidentally get some of
this jelly on your skin, wipe it off immediately and wash the area with
plenty of water as soon as possible. Under all circumstances, keep
the jelly away from the mouth and eyes. Keep discarded materials
out of reach of children and animals, and out of contact with clothing
and furniture, as discarded materials still contain caustic jelly
residue.

A. General Description
The Polaroid Model 204/404 MiniPortrait Camera is a new, optical cut-and-paste
camera that features the unique combination of programmability, low cost, and
exceptional ease-of-use.
Features include programmable LCD graphic display of step-by-step operational
prompts, power-on memory, battery capability, counters for strobe flashes and
packs used, key switch, tripod mount, converging light rangefinder, sync circuit
system with ON/OFF switch, and removable film holder for black-and-white and
color films.
The system consists of a camera head, camera base and AC/DC adapter. The
camera head pivots so that it can swing down into the camera base for storage
and transport, and swing up for picture-taking.
The camera can be positioned either 40 inches from the subject for a larger
head size, or 60 inches from the subject for a smaller head size. At 60 inches, a
supplementary lens is required for proper focus.

inches from the camera lenses to the
subject’s chin. This may be approximate
since the final rangefinder adjustment is
made with the aiming lights during picture-
taking.

made during picture-taking by simply moving the
camera back 20 inches and making final adjustments
with the aiming lights.
