[CA] [CA11] e7d loss of depth

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum Robert,

Q1. There seemed to be multiple updates available, so he did them all. This led to a few auto-pilot issues, such as loss of the deviation table values (detecting magnetics), but we seem to have resolved them and everything seemed to be working well.
A1. Too be clear, updating the MFD's software alone will have no effect upon an autopilot. Please note that the compressed folder containing the LigthHouse II software update file also contains the software update files to update other peripherals which are designed to be updated via a MFD running LightHouse II software. The operator is provided the update to update the software within all peripherals not currently having the latest software installed (default) or only the peripherals selected by the user. As indicated within the LightHouse II software update web page, EV-1 CCU's web page, and within the FAQ found here, after updating an Evolution autopilot's software, updating the Evolution Autopilot's software will necessitate that a Pilot Factory Reset be performed, followed by the Dockside Wizard . The Evolution software update and subsequent Pilot Factory Reset will cause deviation data stored within the autopilot to be deleted, necessitating that the autopilot once again create its deviation table and report the maximum detected deviation.

Q2. By the way, the software update did not resolve the issue, but a touchscreen calibration appeared to resolve it.
A2. As expected. Please click here to view a FAQ addressing this subject.

Q3. The boat is sitting in about 18 ft of water, the depth was reading OK, the maps appeared right. A few days later, we left port for winter storage at another boatyard. The depth reading got lost as we passed through the harbor mouth (about 11-14 ft) but recovered when we got to deeper water, say 20 ft or so. The depth appeared to be OK for the entire trip, but we lost it again when we tried to enter the channel to the boatyard, just when I needed it most. The symptoms are either no depth reading or an absolutely unrealistic value (like 610 ft), and there are big spikes in the fish-finder function, with a few blips that look like about the right value (10 ft). Not only that, the scroll rate seems to speed up and slow down. The unit has worked right all summer but now suddenly this has happened.
A3. The following would be recommended given the reported symptoms following a software update:
- inspect the transducer for signs of fouling and remove an fouling found
- if the transducer is a transom mounted transducer, ensure that the transducer's kick-up bracket has not been triggered. The transducer should be locked into its down position.
- inspect the transducer for signs of damage ... replace or test with another transducer for isolate the sonar fault
- a Sounder Reset should be commanded from the MFD's Fishfinder menu.
- System Settings and Data Reset should be commanded from the MFD's Diagnostics menu. Any waypoint/route/track data of value should be backed up prior to performing this action to permit them to be imported back into the MFD's memory after having performed the reset.
- the Transducer selection menu option should be exercised within the Transducer Settings menu of the MFD's Fishfinder application. The model of transducer installed onboard may be verified per the FAQ found here.
- should the MFD be reporting the symptoms specified, then it would be recommended that the MFD be sent to Raymarine’s Product Repair Center to be bench checked / serviced before your warranty expires.
