CHECKING THE BATTERIES
The Photomic FT N Finder 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 finder. 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
FT N Finder.
To replace weak or worn·out batteries, unscrew the cap over
the battery chamber using a coin
or key and the batteries
will drop ou
t. Make sure that the positive (+) side faces out
when new ba tt e ri es are in stalled.
Caution: Never throw discarded batteries into a fire as they
wi ll explode when heated.

ATTACHING THE PHOTOMIC FTN FINDER
To attach the finder to the camera with the lens in place,
first set
the diaphragm at f/5.6 and place the finder in posi-
tion loosely.
Then depress the finder lock lever and press
down gently on the finder until it clicks into place. The
Photomic FT N Finder has a pair of pincer-type clamps on
the bottom to hold it securely in place. They are loosened by
depressing the finder lock lever.
Mounting the finder
on the camera body without a lens is
simple. Just depress the finder lock lever and press down
gently on the finder until it clicks into place.
To remove the finder, depress the finder lock lever and
press the finder release
button located on the back of the
camera.
The finder will be unlocked and can be lifted out.
Note: When using flash, be sure to set the camera for flash
by lifting up and turning
the milled synchro-selector ring.
Refer
to the "Flash Synchronization" section in the Nikon F
instruction manual.

Shutter Speed Coupling
When the Photomic FTN Finder is attached to the camera,
the shutter speed dial on the camera is covered by the finder
unit. Therefore, an auxiliary shutter speed scale is provided
on
the finder. .
With the FTN Finder in place, twist the shutter speed selector
right and left until it engages
the dial on' the camera and the
two rotate together.
