Wipe battery surfaces clean. Make sure that + signs are facing upwards. Checking the Batteries Always check the batteries after inserting new batteries, when shooting i n cold weather, o r if the camera has no t b ee n used fo r a lo n g t ime .
Rotate the mo de selector dial to the "BATTERY CHECK" position. The audible and visual signals will tell you that the batteries hav e enough power. As the battery power weakens, the signals will become intermittent then vanish completely when they are exhausted.
After th e check, s et b ac k 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.

The OM-4T enables aperture-preferred automatic exposure o n TTL direct light metering (center-weighted, averaged light metering). This mode can be used for most of the subjects under no rma l conditions — when shooting with th e su n behind you, wh en the subject contrast i s n o t to o strong, and so forth.
T T L Direct Light Metering Aperture-preferred automatic exposure allows you to ta ke pictures b y utilizing the lens depth o f field effect ( b lu r re d background, f o r example). P . 95 Set the mode selector lever to the "AUTO" position.

Press th e shutter release to take th e picture. The subject will turn out correctly exposed, regardless of the brightness of the background. The spot metering mode will be automatically cleared after the shutter has tripped, or after 120 seconds have passed, and it will return to the, TTL direct light metering mode.
How t o Clear t h e Spot Metering With the lever at " C L EAR", th e mo d e wi ll return to T TL direct light metering. "SPOT" and mark disappear.
How to Us e the "Multi-Spot Measurement" Mod e Reference P. 101-104 Spot metering is possible in up t o 8 spots. Thi s sample photo shows a backlighted subject.
