PREPARATION FOR USE
Installing the Batteries
The exposure meter in the Photomic finder is powered
by two high-performance silver-oxide batteries mounted
in the battery chamber in the baseplate of the camera.
To install the batteries, first remove the battery chamber
cover (turn it 90° counterclockwise using a coin or simi­
lar object); then, place two 1.5V silver-oxide (button­
cell type) batteries in the chamber, making sure that the
plus (-I-) side of each unit faces out. After inserting and
properly seating the batteries, replace the cover and lock
it to secure the assembly.
Note: Remove the batteries 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 batteries may fail to
function. (See “Tips on Camera Care" on page 36 for additional
information.)
Checking the Batteries
The camera’s film-advance lever serves as the ON-OFF
switch for the Photomic finder. Thus, to check battery
power, perform the following: Pull out the lever just far
enough to uncover the red meter ON index on the top of
the camera; then, look within the finder to see if any of
the LED exposure indicators are illuminated. If any of
the indicators are lit, battery power is sufficient for
proper operation. If none of the LEDs light, battery
positioning should be checked; then, if none of the
LEDs light, replace batteries.
