Charging the Battery (more info is available at this page)

Unscrew the milled screw cap on the front panel and insert the NiCd battery into the battery well. Be sure that the plus side faces out, otherwise the quick charger will not work. Replacing the screwcap switches on the quick charger. Plug the power cord into an AC power source. The white neon power lamp on the front panel will glow green and the red neon charge-indicator lamp goes on with a red light to indicate start of charging.

Note: The NiCd Battery DN-1 provides sufficient power for about one hour of continuous servo operation (at approx. 20° C) between aperture settings of f/1.4 and f/16. If longer operation is required; the use of the- Battery Pack DB-1 or the AC/DC Converter MA-4 is recommended.

Charging time depends on the power remaining in the NiCd battery, but normally a completely depleted battery will be recharged to 80% capacity in about three hours after which the charge-indicator lamp goes out. Unscrew the cap and remove the battery.

Accessories

AC/DC Converter MA-4 This converter adapts the DS-12 attachment to any standard house current and supplies a constant output of 3.6V 400mA DC.

After removing the NiCd battery from the attachment, connect the battery well with the 3.6V output jack on the converter with the connection cord which comes with it. Plug the power cord of the converter into an AC power source, and turn on the power switch on the converter.Before using the converter, check to see that it is working properly by pressing the run-control switch on the DS-12 attachment. If the lamp on the converter glows, then it is operating correctly. The converter also supplies power for the Motor Drive MD-2 so that both the DS-12 attachment and the motor drive can be used simultaneously.

Battery Pack DB-1 The battery pack holds four 1.5V C-type batteries to power the DS-12 attachment. Its built-in voltage stabilizer insures constant light output. To connect the pack, remove the NiCd battery from the attachment and connect the pack to the DS-12 attachment with the connecting cord which comes with the battery pack. Before using the battery pack, depress the runcontrol switch on the DS-12 attachment to make sure that the battery checker on the battery pack lights up. To conserve the batteries, do not leave the battery pack switched on when the pack is not used.Note: Use of the Battery Pack DB-1 enables approximately four times the operation period possible with the NiCd Battery DN -1 .

Nikon F2 36/250-Exposure Data Camera Set

f2datacamera.jpg
The scope of the DS-12 in automatic photography is favorably enhanced in situations requiring precision recording of data when it is used with the Nikon F2 36/250-Exposure Data Camera Set, MF10 or MF11. These sets allow recording of time, data and other data required on a portion of the film frame for convenient reference. It is especially useful for such applications as traffic flow sampling and scientific experiments.The addition of the MD-2 Motor Drive and the MT-1 Intervalometer to the above combination provides for unmanned and fully automatic operation. Connection between the DS-12 and the set is made through the flash synchronization terminal on the DS-1 2.

Caution: MOUNTING MODIFIED 85mm and 105mm LENSES

All Nikkor lenses which have been modified to provide the Al facility can be used in conjunction with the DS-12. However, a small percentage of modified 85mm and 105mm lenses may prove impossible to mount on the camera in the normal way when the DS-12 is attached. Should this be the case with your lens, please follow the instructions below:

1) Remove the Photomic finder, leaving the DS-12 attached to the camera body.
2) Set the lens to its minimum aperture and mount it on the camera in the normal way.
3) Set the mounted lens to its maximum aperture.
4) Lock the meter coupling lever on the Photomic finder in its'up'position.
5) Remount the finder on the camera body.
6) Lower the meter coupling lever to its normal position by pushing the coupling lever release on the finder to the right. Move the meter coupling lever by hand until it engages correctly with the ridge on the lens. Then, proceed as normal.

Brief trouble-shooting:

F2AS ds12.jpg (15k) Loading....
A). If the LED display in the finder fails to light up after the control switch on the EE control attachment is depressed, make the following checks:
1) Check the condition of EE control attachment's battery.
2) Verify that the attachment and the finder are properly mounted on the camera. If not, mount them properly.


B). If the LED display lights up but the EE control attachment fails to operate, check that:
1 ) The A-M switch lever is set at the A position.
2) The attachment's battery is still good.
3) Both the attachment and the finder are properly mounted on the camera.
4) The drive gear reaches either the maximum aperture or the minimum aperture of the lens in use and stays tbere. If the drive gear stays at the minimum aperture, try faster shutter speeds; if it stays at the maximum aperture of the lens, try slower shutter speeds.

C). If the LED display on top of the AS finder DP-12 fails to light up when the eyepiece shutter is closed, carry out the checks listed in "A" and "B."
If, after the above checks have been made and the attachment still fails to operate properly, consult other experienced users or a external qualified service technician. You may also make use of the convenience of the | Message Board in MIR | to post a message.
