CHECKING THE BATTERIES

The Photomic FTN Fmder is powered by two 1.3 volt mercury batteries located
in the battery chamber on the bottom of the finder. To check the batteries, press
the meter switch-off button and observe the needle in the window on top of the
fmder. If the needle swings to the center circle or beyond, the batteries are in
good condition. The two mercury batteries come installed with the Photomic
FTN Finder.

T o replace weak or worn-out batteries, unscrew the cap over the battery cham­ber using a coin or key and the batteries will drop out. Make sure that the posi­tive (+) side faces out when new batteries are installed.

Caution: Never throw discarded batteries into a fire as they will explode when
heated.
