When installing the new battery, please pay attention to the correct position according to instructions (l4)on the bottom of the exposure meter. We recommend that you replace an old battery before going on any long trip. These batteries are available at your photo dealer. Attention: Please use Mallory PX 625 batteries only, if possible. They are especially manufactured for exposure meters. Mallory PX13 batteries will also operate, provided no readings are taken at lower temperatures than 10°C below freezing point (MOF). Both batteries have a lifetime of about 2 years at normal use. There are other batteries on the market with the same dimensions, but of different voltages. These, how- ever, could lead to wrong readings with the Leico-Meter MR. You can check the suitability of another battery of the same dimensions by testing it. If the needle is completely within the white check dot area (ll), the battery is useable.
