  • Page 23: Using The External Sync Mode

    Using the External SYNC Mode The camera can be synchronized externally by inputting an external sync sig- nal. When using external sync, set the clock board’s sync signal input/output switch (SW1) to the external sync signal in (upper switch position) and switches 3 and 4 to the mode switch (SW3), located on the rear panel, to ON.

    4.2 Random Shutter (Fixed V Sync) On the rear panel mode switch SW3, set switch 1 to ON and switch 2 to OFF. Use the shutter speed control switch SW1 to set the shutter speed. The random shutter operates only when the shutter command has been added, so continuous shutter is the normal operating mode.

    4.4 VI Mode Shutter On the rear panel mode switch SW3, set switches 1 and 2 to ON. At this point there will be no image output. When an external VI command is input, expo- sure will occur for the period of the command. This mode is only for non-inter- lace.

  • Page 32: Precautionary Items

    Precautionary Items 4.5 Precautionary Items Observe the following precautions when operating the electronic shutter. The CCD for this camera uses the frame transfer method. At shutter speeds of 1/500, 1/1000, and 1/1500 second, the exposure period and the transfer period conflict with the readout period. There is black output from the line count, which conforms to the shutter speed;...

Use a stable ripple- and noise-free power source. 6.1.2 Heat Reduction To keep the temperature inside the camera from rising in some situations (such as when operating the camera inside a tightly sealed case) it may be necessary to use forced air conditioning.

  • Page 37: Maintenance

    Maintenance 6.2 Maintenance Use a blower to remove dirt or dust adhering to the CCD glass cover. Wiping the glass forcefully can damage the glass or create static electricity that can damage the CCD. Use a soft, dry cloth to clean dirt off the exterior. If it is extremely dirty, use a small amount of a neutral detergent on a cloth to remove it, and then wipe with a dry cloth.
