Adjusting Film Speed

Load the film and turn the MF-12's film speed selector until the white dot click-stops at the corresponding ASA/ISO indication in the ASA/ISO film speed scale.

Note: 1) Do not use films with ASA/ISO speeds not covered by the scale. 2) When using special films or using a technique for increasing or decreasing image density, make test shots first. 3) Make sure the MF-12's film speed selector clicks into the correct film speed setting; otherwise, erroneous results will occur.

Special Usage of the MF-12

instead of the Year/Month/Day or Day/Hour/Minute, you can use the MF-12 to imprint a one or two-digit number of your choice by pushing the ADJUST/R button. In the ADJUST mode for either hour or minute/ second, the numerical indication for minute or hour is underlined.

Note: The bulk-in clock keeps time continuously Thus, should you decide to use the minute indication for the number you enter, bear in mind that after the lapse of one minute, that number will change. Also, the number in the display will not be imprinted while the ADJUST/R button is being held down.

Operation : Shooting

To imprint data, turn the MF-12's data imprint ON/OFF switch to ON. If data imprint is not necessary, make sure the MF-12's data imprint switch is on OFF.

Choose the type of data required for recording - Year/Month/Day or Day/ Hour/ Minute - by pushing the CHANGE button.

Note: The LED indicator flashes as the camera shutter is released. The diamond mark and colon in the display are not imprinted. Time data is underscored as shown in the illustration.

1). With color film, the data is imprinted in red; with B&W film, the data imprinted is in white. Accordingly. it may be difficult to read data imprinted on a red or white ground; 2) To imprint data on a DOUBLE EXPOSURE picture, turn the data imprint switch to OFF after the first exposure.

Battery Issue: Changing Batteries

The life span of the batteries used with the MF-12 is approximately 2 years under conditions of normal use. If the MF-12's LED indicator is continuously lit, change both batteries; changing only one shortens the life span of both batteries.

1) In low temperatures of -10°C or below, the LED may light up continuously even if new batterries are used. Should th~s occur turn off the LED to conserve battery power by pushing the ADJUST/R button. Batteries that temporarily 'deteriorate' due to low temperature can be used again as they recover their capacity when the temperature rises back to normal.
2) The MF-12 is programmed to show 80 1 1 in the display whenever batteries are replaced.

Flash Photography with Flash Unit

For flash photography in conjunction with the MF-12 the use of Nikon electronic flash units with a hotshoe contact is recommended. This type of unit is designed to match precisely the electronic circuitry of the MF-12. With non-Nikon flash units, the MF-12 may not operate properly or could even tee damaged due to differences in the electronic circuitry.
Make sure the data imprint switch is set to OFF when making flash test shots. If the switch is ON data will be imprinted when the flash button of the flash unit is pushed. Also, to prevent accidental data imprinting, the data imprint switch should be OFF every time the sync cord is inserted or the flash unit is inserted into or removed from the hot shoe.

Important:

Do not use cleaning fluids to clean the MF-12.
Use a blower to remove accumulated dust in the three LEDs at the back of the MF-12.

Liquid Crystal Display (LCD)

At high temperatures (approx. 60°C or at whole surface of the display will turn a black making it impossible to read the numeric information. When the temperature goes down the display will return to normal.
Avoid storing the MF-12 in excessively hot places like inside the trunk of a car parked in the sun, doing so may shorten the LCD's life span.
When the temperature drops below freezing point the LCD display's response time nature down; when it goes up again, the display works as before.
Although the MF-12's LCD is of the higher contrast may deteriorate and the display information may become difficult to see after six or seven years of normal use. Should this occur, please contact a authorized Nikon dealer or service facility the display replaced at a nominal charge.

Accessories - Battery Holder DB 3

This optionally available holder accepts two 1.5VAAA type batteries. Since the AAA-type battery has the advantage of big capacity over a silver-oxide battery, it can supply power beyond two years and is rather less affected by low temperature.

To attach the DB-3 to the MF-12, remove the data back's battery chamber lid and, in its place, screw the DB-3 onto the screw hole in the chamber.

Camera Case Base Portion CF-15D

Also optionally available is the CF-15D. When used in place of the lower portion of the camera case of the FE/FM camera, the CF-15D can hold either camera with the MF-12 Data Back attached. This case has "windows" that let you see the MF-12's display and operate the data back as usual
