Losing Depth Display on E90

Welcome to the Raymarine Forum Doug,

It sounds like installation of the DSM was not performed in adherence to the installation instructions for a DSM30/300. The DSM consumes a great deal of power and as such should be installed within a well ventilated space allowing for adequate heat dissipation. Additionally, the DSM should be mounted to a vertical bulkhead with its interface port oriented to face downward. Should your DSM not be installed as indicated within this response, then it is recommended that it be relocated such that it can be installed as indicated within this response.
