INSTRUCTIONS
(This Document)
CAUTION
●Remove the dome type camera (TK-C676 or TK-C655) from the ceiling before attach-
ing the dome cover (KA-C76). Otherwise, the dome type camera may drop from the
ceiling and cause an accident.
●When using a (KA-C76) dome cover in a dark place, remember that the amount of
light transmission is reduced when a (KA-C76) dome cover is attached.
●Due to the dome cover's semispherical shape, near its edge there will be distortion in
the image. The dome camera masks the edge of the semisphere, so when the cam-
era is tilted to the horizontal position the edge of the semisphere enters the picture,
causing the upper edge of the image to appear blacked out or the focus to become
fuzzy.
●When replacing a part, take care not to scratch or stain the lens surfaces or the dome
cover.

●If rubber packing is not attached, it is
necessary to first correctly attach the
rubber packing before attaching the
main unit cover. In this case, attach by
following the procedure described
below.

Rubber
Packing
1. Attach the rubber
packing in the
position shown in
the illustration.
Make sure that the rubber
packing is parallel to the
pipe.
2. Align the tab on the
dome cover with the
groove on the pipe
and fit the dome
cover.
3. Move the rubber packing upward
as shown in the cross-section
diagram.
When performing this, do not remove
the installed dome cover from the pipe.
If the dome cover is removed, the
rubber packing will drop inside the
pipe and it will not be possible to
re-attach the dome cover.
If the rubber packing is not correctly
attached, the dust- and drip-proof
performance of the dome cover cannot
be guaranteed.
