OPERATING PRECAUTIONS
Be careful of the following when you operate the camera.
(1) Cooling method
Cooling of this equipment is done using a Peltier element.
With a Peltier element, when current is supplied, one surface is cooled, and the other surface is
heated. CMOS image sensor is positioned on the cooled side, and cooling is done by discharging
the heat from the heated surface. The camera has an Air-cooling method.
(2) Ambient temperature
The recommended ambient temperature for camera operation is 25 °C. If the ambient
temperature is not 25 ºC, the temperature of the CMOS image sensor may not stabilize.
(3) Protection circuit
This camera's thermoelectric cooling device is protected by a thermal protection circuit.
If the internal temperature of the camera becomes abnormally hot, the protection circuit operates
to inform the user by a buzzer alarm (beep tone) and lighting the camera red LED light while
simultaneously cutting the current supply to the Peltier element. As soon as this protection is
implemented, turn off the power switch, unplug the AC supply. Then remove the cause of the
overheating.
(4) Fan speed
This camera has a function to change a fan speed in 3 stages [Fast, Middle, Slow] to suppress
camera vibration caused by a fan. Fast speed achieves the maximum air volume and it is the
default factory setting.
Fan speed can be changed by software which is called, "DCAM Configurator". (refer to 8-5
"STARTUP DCAM CONFIGURATOR").
(5) CoaXPress interface board
If you use an optional CoaXPress interface board, a message prompting update of the interface
board may be displayed. In this case, an update procedure manual will be displayed when you
click on the message. Update the interface board according to the procedure manual. (refer to 8-
6 "UPDATE PROCEDURE OF COAXPRESS INTERFACE BOARD").
