1.3 REPLACING THE CCD IMAGE SENSOR
F
E
The image sensor is interchangeable only with a specified
image sensor.
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.)
After replacement, all of the adjustments should be performed
from the beginning.
Note that the image sensor is susceptible to static damage. Be sure to take anti-static measures before replacing it. 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.
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 →.
Fig. 1-8
CAUTION
Be careful not to damage the FPC cable when remov­ing the camera cover.
(5) Remove the 2 screws 6 and take out the CCD board. (The
CCD is inserted into the CCD board.)

1.6 CONSUMABLE PARTS
The pan/tilt assembly and the lens assembly of the TK-C675B are consumable parts. Therefore, their servicing is charged to the user even when it occurs within the warranty period.
For the method of checking the operation count, refer to the instruction manual of the remote control software.
See Table 1-2 for the reference periods for the replacement of the consumable parts.
1.8 Replacement of IC ROM (IF board IC27, IC29)
(1) For removing the IC ROM, it is recommended to use a spe-
cial tool, however, two small screwdrivers are substitutable for it.
Part Name Replacement Period
Pan/tilt assembly 1,000,000 times of operation
Lens assembly 400,000 times of operation

REFFERENCE REPLACEMENT PERIODS OF PARTS
WHITCH REQUIRE MAINTENANCE AND INSPECTION
Periodical maintenance and inspection are required to maintain the initial performance and reliability of the unit. Table 1-3 has been complied assuming the use of the unit under room tem­perature, and the periods indicated in the table are greatly vari­able depending on the operating environment and conditions. Lack of proper maintenance, inspection and servicing will result in great reductions of the times indicated in the table and will cause other effects as well.

(2) Insert the portions N of the special tool into the notches P of
the IC socket to pick up the IC. When using small screwdriv­ers, insert their tips into the notches P respectively and pick up the IC with the two screwdrivers.

(3) When in a new IC for replacement, make sure of its orienta-
tion and insert it gently into the IC socket with fingers keep­ing the IC level with the board surface.

1.10 Care in Transportation
In order to prevent damage to the photo interrupter on the IF board during transportation, a bracket has been added. Be sure to remove the bracket before installation by referring to the dia­gram below. Also, be sure to reinstall the bracket at the time of transportation by reversing the removal procedure.
Don't Forget! Be sure to remove the transportation bracket.
A bracket to reduce shock during transportation is mounted when this unit is shipped from the factory.
Be sure to remove this bracket before installation.

HOW TO EXECUTE PROGRAM SOFTWARE (PLSC1209)
2.6 KEYBOARD OPERATION (PLSC1209)
1) Install the MS-DOS MOUSE. COM. (This program can also be used without Mouse.)
2) At the MS-DOS command line, type as follows. A>TK-C675 {/N or /P} [/BW] [/COM2] <Enter>
/N or /P Set type of TV system. The program cannot
start without specified. N : NTSC (U Ver.)
P : PAL (E Ver.) /BW Set if the monitor is Black & white. /COM2 Set if a serial mouse is connected to the
COM1 serial port to allow camera data com-
municate via COM2. If not specified, COM1
becomes the main communication port auto-
matically.
3) At the “Welcome” message, click <OK> or press [ENTER] key. Follow the message appearing on the display to prepare and execute each setting.
4) When the main window is displayed, data communication begins. However, if due to faulty connection or other abnor­mality, the program stops. Observe the check indication at the lower right of the screen. If indication is “NG”, check the cable connections and camera power. When indication is OK, the program operation starts. If communication is abnormal, press the [Break] key to terminate the program.
5) When the program starts, check the TV system indication of the main window. If this is incorrect, restart the program and correct the TV system entry. To terminate the program, click the EEPROM menu, then click Quit (or press [Crtl] + [F4] keys).
NOTE
For Remote Control Software (PLSC1210), See instruc­tion manual attached to the software. Not described on this Service Manual.
Although a mouse is recommended for using this program, it can also be operated from the keyboard in cases when a mouse is not available. The commonly use keys are as follows.
Key Function [Alt] Menu selection [Enter] Confirm [Esc] Cancel [Up] or [Shift] + [Up] Cursor shift [Down] or [Shift] + [Down] Cursor shift [Left] or [Shift] + [Left] Cursor shift [Right] or [Shift] + [Right] Cursor shift [Tab] or [Shift] + [Tab] Item select [Insert] Insert or Overwrite text [Delete] Delete text [Back space] Cursor backspace during

Caution
If the camera power supply is cut off during program op­eration, communication error is produced. The program stops and operations are not recognized. Communication and program operation resume when camera power is re­stored. However, if communication error occurs during adjustment or EEPROM data editing, first terminate, and then restart the program again.
