1.3 REPLACING THE CCD IMAGE SENSOR
F
E
䡵 The image sensor is interchangeable only with a specified
image sensor.
䡵 New image sensors and crystal filters should be handled so
as not to leave fingerprints or grease on their glass surfaces.
To remove attached dirt or grease, blow on the glass surface
until it becomes misted then wipe it gently with a cotton
swab. (Do not use alcohol or other similar substances.)
䡵 After replacement, all of the adjustments should be performed
from the beginning.
䡵 Note that the image sensor is susceptible to static damage.
Be sure to take anti-static measures before replacing it.
䡵 After an image sensor has been removed, an electrical charge
may remain on the terminals of the camera circuit for a certain period of time.
If a new image sensor is inserted into the socket in this condition, the image sensor may be instantly damaged by the
remaining electric charge. To prevent this happening, wait a
while (2 to 3 minutes) after removing an image sensor until
inserting another one in the socket.
䡵 After the CCD board has been removed from the lens as-
sembly, the back-focus adjustment should be performed
again.
(1) Remove the camera as described in 1.2.
(2) Remove the 3 screws 3 , the 3 screws 4 and the 2
screws 5 .
(3) Lightly push the section of the right camera cover F .
(4) Remove the left camera cover E in the direction as indi-
cated by the arrow →.

Operating precautions
● To save energy, when it is not being used turn the system's
power off.
● This camera has been designed for indoor use. It cannot be
used outdoors.
● This camera has been designed exclusively to be hung from
the ceiling.It may malfunction if it is placed on a surface or if
it is tilted.
● Do not install or use the camera in the following places.
• In a place exposed to rain or moisture.
• In a place with vapor or oil soot, for example in a kitchen.
• In a temperature outside the operating temperature range
(-10°C to 50°C).
• Near a source of radiation, X-rays, strong radio waves or
magnetism.
• In a place subject to vibration.
• In a place with excessive dirt.
● Insufficient head ventilation of the camera may cause a malfunction.
Be careful not to block the ventilation to the camera.
● If this camera and the cables connected to this camera are
used where there are strong electromagnetic waves or where
there is magnetism present, for example near a radio or TV
transmitter, power transformer or an electric motor, the picture may produce noise and the colors may be affected.
● This camera incorporates an AGC circuit. As a result, when
it is used under low light conditions, the camera sensitivity
is automatically boosted and the picture may look uneven.
This is not a malfunction however.
● When the AGC is ON in the auto iris mode, varying the iris
with the IRIS control button may not change the picture
brightness due to the gain boost function. In this case, switch
the AGC OFF or set the iris mode to manual.
● In auto iris mode, the IRIS control buttons may not function
under certain brightness conditions (i.e. when a sufficient
amount of light cannot be obtained). In this case, set the iris
mode to manual.
● The white balance setting when used under a fluorescent
lamp should be ATW (Auto White). If it is set to MANU (Manual), the white balance may not be adjustable.
● When presetting this unit
’ s position, turn it on and wait until
it has warmed up sufficiently inside (about 30 minutes). This
is to avoid a change in the lens focus due to a rise in
temperature after installation.
● When this camera is used in the AUTO white balance mode,
the recorded colors may be slightly different from the actual
colors due to the operational principles of the auto-tracking
white balance circuit. This is however not a malfunction.
● If a high-intensity object (such as a lamp) is shot, the image
on the screen may have vertical lines (smear) or blur (blooming) at its periphery. This is a characteristic of the CCD, and
is not a defect.
● The electronic shutter of this camera has been set to 1/60(1/
50) sec. at the factory. When the camera is used under a
fluorescent lamp or in an area with a local power frequency
of 50/60 Hz, change the shutter speed to 1/100(1/60) on the
remote control unit. (The sensitivity deteriorates slightly with
a shutter speed of less than 1/100(1/60) sec.)
Utype (Etype)
● When the camera is used to monitor the same position continuously for 24 hours or more, the contact resistance of the
horizontal rotary parts may increase after long hours of use,
and the picture may be affected by noise interference or the
remote control operation may become unstable.
To prevent this, turn the system power off and on at least
once a week (to initialize) and also clean the contacts.
● Do not touch the dome cover of the lens directly with your
hand, contamination of this cover will lead to a deterioration
of the picture quality.
● Observe the following when carrying out camera maintenance.
• Turn the power OFF before proceeding to carry out main-
tenance.
• Clean the dome cover lens using a lens wiper cloth (or a
tissue).
If it is contaminated seriously, clean the contaminated part
with a cloth (or a tissue) which has been soaked in a solution of water and a neutral detergent.
● In order to reduce the generation of unnecessary signals,
be sure to install the provided ferrite cores when connecting the cables. (See
“How to use the ferrite core
” on page 9)
● Some subjects may not be brought into focus with the autofocus facility of this unit. Focusing will be made easier by
locating a subject with highly contrasted vertical stripes near
the center of the image.
● Optional controller is required to use the TK-C675B camera.
Please contact your local dealer or installer for more information about this controller.
Safety precautions
• As this unit contains parts which rotate at high speeds, it
should be installed in a place suitable to withstand the possible vibrations and to support the unit weight of 2 kg. If the
ceiling is made of dressed-face plywood, plaster board or
another material which is not strong enough to support the
unit, reinforce the installed surface by using a reinforcing
material (including plywood). If the reinforcement is insufficient, the monitor picture may be blurred due to vibrations
or in the worst case the unit may fall.
• Installation of this unit requires expertise. Please contact
your dealer for details.
• The ceiling to mount the TK-C675B has to be strong enough
to support ten times the weight of this product.
If the ceiling is not strong enough, make sure to apply reinforcement to the ceiling before installation.
• Be sure to tighten the screws and nuts securely, Insufficient
tightening may cause the unit to fall from its mount.
• The unit is to be powered by an AC24V.

1.
Make a hole (90 mm dia.) in the ceiling for passing through the
connection cables.
2.
Connect the cables to the terminal board.
Turn the power of all the connected equipment to OFF before
connecting the cables.
Remove the terminal board cover and connect the video signal
cable (coaxial cable),the control signal cables (x 4) and the 24 V
AC power cables (x 2).
●24 V AC power cables
Connect the 24 V AC power supply to the AC 24V terminals on
the terminal board. To prevent connection errors or a cable disconnection, we recommend the use of lug plates for the connections.
The following table shows the connection distances and connection cables provided that 2-conductor VVF cables (vinyl-insulated
vinyl sheath cables) are used.
Installation
●Control signal cables
These cables should be connected only when it is required to
control the camera using the RS-422A or RS-485 signals. The
use of 0.65 4-conductor twisted pair cables is recommended. With
these cables, the maximum extension distance is 1,200 m.
●Video signal cables
Connect the coaxial cables to the video signal output terminals.
Treat the tips of the coaxial cables as shown on the left before
connection.
After having connected all of the required cables, again attach
the terminal board cover.
3.
Attach the ceiling mount to the ceiling.
Attach the ceiling mount to the ceiling using 4 screws, while paying attention not to foul the connection cables.
Use M4 or No. 8-32 UNC screws and bolts for attaching the mount.
If using wood screws, use those with a diameter of 4.1 mm.
The screw head height should be no more
than 4 mm.
• If thin cables are used(i.e. with a high resistance), a significant
voltage drop will occur when the unit is at its maximum power
consumption (pan, tilt, zoom operated simultaneously). Either use
a thick cable to restrict the voltage drop at the camera side to
below 10%, or place the AC24V power supply near to the camera.
If voltage drop occurs during operation, the performance will be
unstable.
• Attach the cable conductors so that they do not come into contact with the drop prevention wire.
• Be sure to connect the 24 V AC cables correctly. Otherwise the
camera will be damaged.
CAUTION
The ceiling to mount the TK-C675B has to be strong enough to
support ten times the weight of this product.
If the ceiling is not strong enough, make sure to apply reinforcement to the ceiling before installation.
To prevent accidental dropping of the camera, connect the ceiling
plate or channel with the ceiling mount using a safety wire. Thread
the safety wire through the safety wire hole on the ceiling mount.

Troubleshooting
SymptomCause (Information)Remedy
Video is not
output.
• Is there a problem in the power cables connecting the camera to the power supply unit.
(If the power cables are too long or are of the
wrong size, the correct voltage may not be
supplied due to an increase in resistance.)
• Connect low resistance cables.
• Place the AC24V power supply near to the
camera.
(Check that the voltage supplied to the terminal
board is as rated when the camera is operating,
that is, when the rated current flows through it.)
Power cannot be
turned on.
• Are cables connected properly to the terminal
board on the ceiling mount?
• Was the 24 V AC power supply switched ON
and OFF repeatedly?
(The protection circuit may be activated when
the power is switched ON OFF ON within 5
sec.)
• Connect cables properly.
• Once the 24 V AC power is switched OFF, it
should be switched ON again only after a
lapse of more than 5 seconds.
The camera
moves from the
preset position.
• Has the panning been rotated manually for
cleaning, etc., while the power was on?
(The camera controls the panning position
based on the initial operation at the time the
power is turned on. If the camera position is
changed manually after the initial operation.
the preset camera position is displaced.)
• Switch the camera power supply OFF then ON
again.
Power can be
turned on, but it
later turns off
when the pan/tilt
unit is operated.
• Is there a problem with the power cables connecting the camera to the power supply unit.
(If the power cables are too long or are of the
wrong size, the voltage may drop due to an
increase in resistance during the panning
operation.)
• Change the power cables to ones of a lower
resistance
(i.e. thicker or shorter) cables.
• Place the AC24V power supply near to the
camera.

䡵 REPLACING SUBMINIATURE “CHIP” PARTS
• Some resistors, shorting jumpers (0 Ω resistance), ceramic
capacitors, transistors, and diodes are chip parts. These chip
parts cannot be reused after they are once removed.
• Soldering cautions:
1) Do not apply heat for more than 3 seconds.
2) Avoid using a rubbing stroke when soldering.
3) Discard removed chips; do not reuse them.
4) Supplementary cementing is not required.
5) Use care not to scratch or otherwise damage the chips.
• On Replacing Chip Parts
Use a soldering iron(rated temp: 260-300°C,17 W) which is
sharp in the tip and high in the insulation.
Notes:
• There are many mini flat ICs used in the camera. When
unsolder them and cutting off IC pins to remove them, do
the board damaged nor come off.
• When soldering is tried twice or more for the same chip
parts, carefully wipe flux dusts off with cloth moistened
with absolute alcohol, otherwise the IC may malfunction
owing to remaining dusts.
