Macro 5 SLR Camera

General

The Polaroid Macro 5 SLR (Figure 1-1) is a fully automatic, close-up portable camera. It is designed for medical and dental documentation, quality control, law enforcement, and other applications that requires close-up photographs.

The Macro 5 SLR has two built-in electronic flash units that provide even illumination. It also has a microprocessor-controlled exposure system that automatically sets the camera for correct exposure at all magnification settings.

The Macro 5 SLR produces automatic exposures at:

• 0.2x (20%)

• 0.4x (40%)

• 1x (100%)

• 2x (200%)

• 3x (300%)

The lens for each exposure setting is self-contained within the camera's manually rotating turret, so there is no need to attach any accessories when changing camera magnification.

3. Set the lighten/darken buttons to the desired exposure (trim). Notes: • Makes the picture lighter or darker to enhance the specific details

of the subject.

• Normally the camera provides the correct exposure for subjects of average brightness.

• Each setting adjusts the flash output by 1/3 f-stop. The center

light is the nominal setting.

• White arrow lightens the picture (increases exposure).

• Black arrow darkens the picture (decreases exposure).

4. Set date/time selector buttons to the desired date/time sequence to be printed on the picture.

Note: This function is optional. It can be shut off if desired. For detailed

information on how to select, or set, the current date/time, refer to the Macro 5 SLR User's Guide.

Date Display: The five printable date sequences are as follows:

• No Print Mode - - -

• Month/date/year 8 7 '95

• Day/month/year 7 8 '95

• Year/month/day '95 8 7

• Day/time (24-hour clock) 7 13:30

5. Set the flash control buttons (left/right or both). The red charging status light above the flash control button blinks while the flash units are charging. The green status lights come on when the flash unit/s are fully charged (ready).

Note: Normally both flash units will be on. For detailed information on how to

select either the left or right flash, refer to the Macro 5 SLR User's Guide.

Picture Taking

1. Turn on the camera by lightly pressing the shutter (S1/S2 switch) button. This closes the S1 switch.

Closing the S1 switch:

• Turns on the top and bottom range (aim) lights to focus the camera.

• Latches the camera's power on.

• Starts the strobe charge cycle (charged before self-check routine started).

• Starts the camera's self-check routine. Notes: If the shutter button is pressed all the way in at this time, the

camera's electronics inhibit it from taking a picture (camera beeps indicating strobes not charged). The strobes must be fully charged and the camera’s status lights must be green indicating that the camera is ready before a picture can be taken.

The two range lights stay on as long as the button is lightly pressed. If the button is released, the two range lights go off in approximately fifteen (15) seconds. Press the shutter button lightly to turn them on again.

2. During this self-check routine, the microprocessor controller initializes (resets) the camera's electronics and checks the status of:

• Control panel settings

• Magnification setting - position of turret (remembers last magnification

setting)

• Lighten/Darken (remembers last exposure setting)

• Film door (open/closed)

• RS232 receptacle (connected or not connected)

• Battery (low?)

• Picture count (0?)

• End-of-pack

• Auxiliary receptacle (connected or not connected)

• Internal timer (updated)

• Strobes (charged/not charged) Note: This self-check routine starts a thirty (30) second continuous test loop

that times out if no action is taken. It continually checks the status of the camera. If no action is taken during this thirty (30) second continuous test loop, the camera automatically powers down (shuts off). It takes an action (button pressed, setting changed, picture

taken, etc.) to keep it powered up.

Repair Manual

Macro 5 SLR Camera

3. While this self-check routine is checking the camera's status, focus and frame the subject.

For detailed information on how to properly focus and frame the subject, refer to the Macro 5 SLR User's Guide.

4. Once the camera is properly focused and the status lights are green, press the shutter button (S1/S2) all the way in to take the picture. This action closes the S2 switch.

Closing the S2 switch:

• Fires the strobes.

• Actuates the shutter. Note: The camera will take a picture only when it is properly focused, the

strobes are fully charged, and the self-check routine is in progress.

5. The picture will automatically eject from the camera when the shutter button is released.

Note: The camera powers down (shuts off) when:

• Picture count reaches zero (0).

• Self-check continuous loop times out - no camera activity for thirty (30) seconds (button pressed, setting changed, picture taken, etc.).
