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. The FL-400
sensor is positioned on the cooled side, and cooling is done by discharging the heat
from the heated surface.
The camera has two cooling modes, Air-cooling mode and Water-cooling mode.
Cooling mode can be changed by software which is called, "DCAM Configurator". After
cooling mode was changed, the camera memorizes the last setting as the default
setting for cooling. The present cooling mode set-up of this camera can be checked
using "DCAM Configurator".
Note
Cooling method
Air-cooling mode
(Forced air-cooled)
(Default)
Water-cooling mode
(2) Ambient temperature
The recommended ambient temperature for camera operation is 20 °C.
Both water-cooling or air-cooling are available as cooling method, FL-400 sensor
cooling temperature is more stable under water cooling operation.
(3) Protection circuit
A double protection circuit protects this camera's thermoelectric cooling device. If the
heat dissipater becomes abnormally hot, the protection circuit sets off a buzzer alarm
and stopping current supply to Peltier element simultaneously.
When the protection circuit is activated immediately turn off the power switch. Then
investigate cause and remove the cause of the overheating and restart the camera.

• A software "DCAM Configurator " is in a CD-ROM of DCAM software.
Detail
The heated side of a peltier element is cooled by a fan inside the
camera. When the camera is turned on, the fan starts rotating and
cooling is started.
Circulating water cooler (Optional) is used for cooling the heated side
of a peltier element. Cooling does not start just turning on the camera.
Cooling water circulation must be started before start operating the
camera in water-cooling.
A fan inside the camera does not rotate.
(Please refer to 8 [WATER COOLING] for instruction of water-cooling.)
• Do not switch to water-cooling mode when water-cooling is unnecessary.
