Konica Minolta T3 manual Check of Batteries

Check of Batteries

A mercury battery will be fully usable over a period of one year in normal circumstances. There will be a sudden drop in voltage when its days are numbered. When the meter needle visible in the finder is immovable at a bright place, it means that the battery has run down. You may also check the battery in the following manner:

1.While the Lens Release Button (27) is kept depressed, take off the lens, as it is turned counterclockwise. (See P.25)

2.Lift the outer ring around the Shutter Speed Dial (20) and set the film speed to ASA 100.

3.Turn the shutter speed dial and set it to 1/125 sec.

4.While the finder is being looked into, detach the Meter Switch (3) from the position of "OFF" and depress it in the direction of "C". If the meter needle (49) comes in alignment with the Battery Check Mark (50) between the aperture readings of f/8 and 11, it means that the battery is fully serviceable. If the needle has failed to

come to that point or gone farther down from that point, it is advisable to change the battery with a new one.

•Note that the all the marks necessary for the checking of the battery are colored in red. Make sure that the meter needle will come over the red mark when the film and shutter speeds are set to the red and the lever is depressed in the direction of the red-colored alphabet "C". Check the battery in the correct order shown on the battery check seal on the bottom of the camera body.

•The meter takes two 1.35V National H-C, Mallory PX-675 or Eveready EPX-675 mercury battery cells. Care must be exercised in selecting the cells as there are cells which look identical in shape but differ in stipulated voltage, such as battery cells.

•In the event that your camera is not to be used over a long span of time, take out the mercury battery cells and keep them in a place free from moisture.
