Pull outward at the top of the hinge until the back cover is fully removed from the camera body. To mount the Info Back-2 to the camera, reverse procedure is required.

 


 

INSTALLING THE BATTERY:

Slide out the Battery Compartment Cover (Fig. 3) from the front of the Info Back-2. Pull out the Battery Terminal (with the 2 leads attached) from the Battery Compartment (Fig. 4). Plug in a 9 V transistor battery (S-006P, 6F22, Mn1604 type or equivalent). The correct positioning of the positive (+) or negative (-) end of the battery is shown on the battery. Insert the battery into the Battery Compartment with the battery terminal upward (Fig. 5) and replace the battery compartment cover. NOTE: The mode Selector Switch should be set to the "OFF" position when the unit is not in use. Failure to do so will result in completely drained battery in approximately four days. The Info Back-2  will make approximately 800 imprints with a fresh battery.4.butkus.org
 
 

BATTERY TESTING

Turn the Mode Selector Switch (Fig. 6) to INPUT position and depress the Battery Check Button (Fig. 7). When the battery is in good condition (battery potential is high enough), an audible signal will beep and the word "BATTERY OK!" will appear in the monitor window. When battery voltage is too weak to operate, no audible signal will be heard. When replacing the battery the Mode Selector Switch should be set in the OFF position. NOTE: Battery testing can be executed with the Mode Selector Switch in the INPUT or MEMORY position.

DATA INPUT:

1. Set the Film Type Selector Switch to the desired film speed (ASA/ISO 100 or ASA/ISO 400).

2. Set the Mode Selector Switch (Fig. 9) to the INPUT position, the Number "30" will appear in the LCD monitor window.

3. Check the battery, then input the data.4.butkus.org

4. After each input of data, the remaining number of possible inputs of information will appear. Up to 30 characters can now be keypunched into the unit by depressing the appropriate character keys. This unit is equipped with dual stage audible signal.
Stage one: a single audible signal which indicates that the unit is properly recording the first 25 characters of information.
Stage two: a dual audible signal that warns you when the last five (26th30th) characters of information is being recorded by the unit and the unit is approaching maximum input level.

NOTE: Do not depress the keys with any sharp objects such as a ball point pens or a knife.

5. Set the Mode Selector Switch in MEMORY position (Fig. 10) from INPUT position. The word "MEMORY" will appear in the LCD monitor window and remain visible for a few seconds.

6. Depress the shutter of the camera and take the picture in the normal manner. NOTE: Information will not be clearly imprinted on the bottom of the film
frame when the bottom of subject is white or yellow.

7. Now you are ready to imprint the data onto the film. Simply depress the IMPRINT Button (Fig. 1 1). An audible signal will then be heard indicating imprinting has begun. When all information has been transferred to the film, a triple audible signal will be heard. The word "IMPRINTED" will appear in the LCD monitor window. As long as the Mode Selector Switch is set in MEMORY position, the information will be stored indefinitely and can be repeatedly imprinted on the film frame, picture after picture.

NOTE: Do not advance the film unless the word "IMPRINTED" appears in the LCD monitor window. When the film is advanced during the imprinting process, the information on the film will be garbled.4.butkus.org

8. The data being stored in memory can be cleared by switching the Mode Selector Switch to the INPUT or OFF position. NOTE: The battery will last for approximately 4 days if the Mode Selector Switch is left in the MEMORY position. (These times are for the old type batteries, not current year 2000 brands.  Still, you must turn it off)

CAUTIONS:
1 Do not depress the keys with any sharp objects such as a ball point pen or a knife

2 Do not use cleaning solution such as lacquer, thinner or MEK, it will dissolve plastic components

3. To clean the unit, use a soft cloth without any solution.

4. Rough handling may result in damage to the unit.

5. Do not print twice on the same film frame otherwise the data will be garbled.

6. When using with a power winder, release the shutter after data are imprinted. Data can not be imprinted with the power winder in continuous use.4.butkus.org

1. At high temperatures (60°C or over), LCD (Liquid Crystal Display) may turn black Do not leave the unit in any place under the direct rays of the sun for a long time
