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.

Repair Manual Model 204/404 MiniPortrait Camera

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.

Note: For distances of 60 inches, adjustments can be made during picture-taking by simply moving the camera back 20 inches and making final adjustments

with the aiming lights.

6. Plug one end of the AC Adapter into the power cord socket (M) of the camera and the other end into the power source. Or, use the optional 12 volt battery.

Aim Light Adjustment

Check the vertical alignment of the aiming lights as follows:

1. With the system on, face the camera toward a wall at a distance of 40 inches.

2. Set the camera’s aiming switches to 40 inches.

3. Place a target, consisting of two intersecting lines, on the wall.

38

Repair Manual Model 204/404 MiniPortrait Camera

4. Press the aiming button and move the camera away from the target until the converging light beams are aligned on the target. In the illustration below, both beams are properly aligned on the horizontal axis.

4A

However, if one light is higher than the other, as shown below, it must be adjusted downward.

4B

Lower the Aiming Light as follows: (Refer to Figure 3-4)

a) Access “Aim Lamp” in the diagnostic menu as described in Section 2 of

this manual. The Aiming Light will blink for one (1) minute so that it can be checked and adjusted if necessary.

b) Insert a 1/32 inch allen wrench into the Aiming Light adjustment opening

in the Rear Housing (Figure 3-4). Note: There are two adjustment openings, one for the left Aiming Light and one for the right Aiming Light.

c) Turn the adjustment screw clockwise until the beam is lowered into

vertical alignment with the lower beam as shown in number 4A above. At 40 inches, the beams will be superimposed for proper framing on the subject’s chin.
