be responsible for poor results or damage of the OM-4T .

Dioptric Correction
The OM-4T permits dioptric adjustment according to your eyesight.
Remove the body cap.
4

Pull out the diopter adjustment knob.
Turn and adjust the knob so that the matscreen
appears sharp.
Push the knob back in until it locks.
5

Mounting the Lens
Remove the rear lens cap.
Align the red dots and rotate the lens clock-
wise until it locks.
6

Loading the Batteries
Do not use different types of batteries or new and old batteries at the same time. If you are not
likely to use the camera for a long period of time, remove the batteries before putting it away.
Remove the battery cover.
8

Wipe battery surfaces clean. Make sure that +
signs are facing upwards.
Checking the Batteries
Always check the batteries after inserting new batteries, when shooting in cold weather, or if the
camera has not been used for a long time.
9

Rotate the mode selector dial to the "BATTERY
CHECK" position.
The audible and visual signals will tell you that
the batteries have enough power. As the battery
power weakens, the signals will become intermittent
then vanish completely when they are exhausted.
Replace the batteries.
10

After the check, set back the dial.
When checking the batteries, the audible and visual signals will automatically turn off in 30
seconds. If you then press the shutter release, the shutter will trip in the auto exposure mode.
Loading the Film
11

Pull up on the rewind knob to open the camera
back.
Tear off the top of the film box and insert it
into the memo holder. It will remind you which film
you are using.
Insert the cartridge and push down the film re-
wind knob. (Always load thefilm in the shade.)
12

Insert the film leader into the take-up spool.
Wind the film and make sure the sprocket teeth
catch both the upper and lower film perforations.
Take up the slack by turning the rewind crank
clockwise.
13

Close the camera back until it clicks into place.
Face the camera toward light and take two
blind shots. This will bring the film to thefirstframe.

Align the exposure line A with the index B .
If the exposure compensation dial does not turn to the
desired ISO number, set it once at an intermediate value then
repeat the procedure.

The OM-4T enables aperture-preferred automatic exposure on TTL direct light metering
(center-weighted, averaged light metering). This mode can be used for most of the subjects
under normal conditions — when shooting with the sun behind you, when the subject
contrast is not too strong, and so forth.
