Inspect the antenna connection and cabling at least once per season to ensure no corrosion has developed. If moisture or water ingress is detected in the cabling, replace it immediately. Keep the unit dry when possible and store your boat covered during long-term mooring to avoid UV exposure. Additionally, test the DSC feature regularly to ensure it’s working correctly with your GPS setup.
