eS128 w/CPT120 - rv6av8r - 06-19-17 12:23 PM I just installed the above combo. The Transducer came with a suppression ferrite but I can find no mention of it in the installation instructions. Is it needed? If so, where should it be placed. Thanks RE: eS128 w/CPT120 - Chuck - Raymarine - Moderator - 06-20-17 03:17 PM Welcome to the Raymarine Forum rv6av8r , Generally, it is advised that transducer cables not be bundled with or routed in close proximity to other cables. RF Chokes are supplied with some products to meet CE certification for the prevention of stray RF emissions. If supplied, RF chokes should be attached to the plug end of product's power cable. The RF choke should be positioned as close as is permissible to the power cable's plug.
