CAUTION: After connecting the DC power cable, NMEA IN/OUT leads, external speaker lead and hailer/foghorn lead, cover the connector and leads with an adhesive tape as shown below, to prevent water seeping into the transceiver.

Rubber vulcanizing tape

*The supplied ferrite core must be attached to the NMEA in/out leads and DC power cables as illustrated at left. Fix the ferrite core near the transceiver with the two supplied ties to prevent it from moving.
