5.3.2.3 Connector Maintenance
Proper connector maintenance is crucial to the prevention of
connector failure that may result in failure of the sonar system and
possible water damage to the sonar head. The following steps
should be taken whenever the connectors are assembled, or at
regular intervals as outlined in the “Maintenance Schedule” section
above.
1. Wipe connectors clean of old grease and dirt with a lint free
cloth.
2. Inspect the connector’s metal contacts and sealing surfaces for
corrosion, wear or damage. If problems are found, return the
unit to a qualified Simrad service facility for replacement of the
connector!
3. Apply liberal amounts of Dow Corning “55” grease to each of
the connector prongs and to the sealing surfaces of the
connectors. Do not use a silicone rubber adhesive sealant!
4. Press connectors together until fully seated. Excess grease
should be squeezed out of the connector sockets.
5. Hands tighten the locking sleeve. Do not use a wrench or
pliers!
6. When separating the connectors, avoid wrenching or bending
connector.
WARNING: Failure to correctly maintain connectors may cause
damage to the system and will void the warranty.
5.3.2.4 Excessive Impacts
Though the FS Trawl Unit is designed for the harsh fishing
environment, excessive impacts to the trawl unit or the individual
components may damage them.
Excessive impacts to the trawl unit usually result in physical
damage to this housing. However with the newer, more durable
urethane housing, excessive impacts to the trawl unit may NOT
cause physical damage to either the trawl housing or the exterior of
the individual electronic units, but may result in damage to the
electronics.
