Appendix 179 z Before installing the batteries, wipe the battery terminals well with a dry cloth. If the battery terminals are soiled with oil from one's skin or other dirt, the number of recordable images may be considerably diminished, or the amount of time the camera can be used may be reduced. z At low temperatures, battery performance may be reduced and the low battery icon ( ) may appear earlier than usual. Under these conditions, restore the battery performance by warming it in a pocket immediately before use. z Do not put the batteries into a pocket together with metallic items such as a key ring. The batteries may be short circuited. z When not using the camera for long periods, remove the batteries from the camera and store them separately. If the batteries are left inside the camera, the camera may become damaged from battery leakage. WARNING Never use damaged batteries or batteries whose outer seal is completely or partially missing or peeled off, as there is risk that such batteries may leak, overheat, or burst. Always check the seals on store-bought batteries before loading them, as some batteries may come with defective seals. Do not use batteries with defective seals. Never use batteries that look like this. Batteries with all or part of the seal (electrical insulation sheath) peeled off. The positive electrode (plus terminal) is flat. The negative terminal is correctly formed (protruding from the metal base), but the seal does not extend up over the edge of the metal base.
