The meter is operated by a button on the side of the mirror housing, which is pushed back to stop down the lens and activate the meter. Film speeds for the meter are set by a scale inset into the top of the shutter-speed dial. The meter requires a PX625 mercury battery or equivalent; otherwise camera is entirely mechanical.
