connected to the POWER IN terminals of the VCM100.
• Do NOT connect additional power switches to the cable providing
the power feed to the VCM100.
• All power connections between the VCM100 and the power
source must have appropriate fuse protection.
• All power connections must be of high quality to minimize
resistance and to remove the risk of accidental shorts.
• The VCM100 SCREEN terminals must be connected to your
vessel’s RF ground system.
