SECTION 6: CLEANING
6.1 General Cleaning Information
•
The aluminium camera body can be cleaned with a soft cloth and glass cleaner.
•
Never spray liquids directly on the camera; apply cleaning solution to the cloth, then wipe the
camera body with the dampened cloth.
•
Do not use abrasive or other detergents to clean the camera.
•
Dust may also collect on the cooling fans located on the back of the camera head.
•
From time to time, it may be necessary to clear away the dust with a small brush. The fans disperse
heat as it radiates away from the heat sink. Should the airflow become blocked, the thermoelectric
cooler may run a few degrees warmer than normal and the camera body could overheat, causing
damage to some of the more sensitive components.
6.2 Cleaning the Camera Window
At some point, it may become necessary to clean debris from the CCD imaging sensor window. Cleaning
the camera window can provide effective results providing you carefully follow these step-by-step
directions.
WARNINGS
•
Only open the shutter using camera control software.
•
Do not attempt to manually open the shutter with your fingers or other objects.
•
The glass is located very close to the CCD imaging sensor. Scratching the window may
require it to be replaced.
•
Cleaning the window is done entirely at the customers risk, window replacement is not
covered under the warranty. It’s better to under-clean than to over-clean.
