Main Unit, Radio (353)
IMPORTANT:
The optic cables should be handled carefully so as not to distort the signal.
- It is extremely important that the two leads in the connector are not confused.
- The cables cannot be spliced.
- The lead must not be bent to form a curve with a radius of less than 25 mm.
- The lead must not be subjected to temperatures greater than 85 degree C.
- The lead ends should be kept free from dirt.
- The lead must not be subjected to blows that could cause the transparent plastic to whiten, thereby damping light strength. This could cause disruptions in communication.
- The lead should not be stretched across a sharp edge, which would cause increased damping of the signal.
WARNING: The red visible light is of laser class 1. Do not look directly into the optic fibre or the control module connector at close range. At a distance of less than 20 mm from your eyes to the light source, your eyes could be damaged.
