PREPARATION FOR USE

Installing the Battery

The exposure measurement and shutter control circuits of the EL2 are powered by a single 6-volt (type 544) battery mounted in the battery chamber at the bottom of the mirror box. To install the battery, first remove the lens (if mounted) from the camera body (see page

42)and lock up the mirror (turn the lockup lever upward as far as it will go, as described on page 39) to gain access to the battery chamber. Then, open the battery chamber (slide the lid to the left, then up) and install the battery, making sure to properly align the positive (+) and negative (-) terminals of the battery as depicted on the interior of the lid. After

inserting and properly seating the battery, snap the chamber lid shut, unlock the mirror and remount the lens preparatory to shooting.

Caution: Should the battery be installed incorrectly (i.e., in the reverse direction) in the chamber, its energy will be depleted in a matter of minutes; thus, take extra care to insert the battery properly. Also, be careful not to touch the shutter curtain and mirror surface while installing the battery.

Note: Remove the battery when the camera is not to be used for a long period; this will prevent leakage within the camera. Also, keep the camera as warm as possible when operating under cold-weather conditions; otherwise, the battery may fail to function. (See "Tips on Camera Care" on page 40 for additional information.)
