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.
