Losing Depth Display on E90

[Doug Brown]

I have an E90 multi function display, equipped with a DSM and SeaTalk hs network. The system has been in operation for several years and worked fine.
All units are located inside the dash on the flybridge.
It appears that when the DSM gets warm, we lose the depth display, while everything else works fine. (when it is cool, it is ok).
Do you have any suggestions, other than relocating the unit to another location, which is not an easy task? ie: any software updates available, etc?
Thank you!

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.
