This sheet includes the 8242XS’s commands, and transponder frequencies. Acoustic Efforts should be made to ensure that there is a clear acoustic path between the 8242XS Transducer and the source (typically a dunking Transducer from a deck unit). Structural elements of a mooring system which have significantly different acoustic impedance than that of seawater will cause absorption or reflection of acoustic signals, which will degrade the operation of the unit. -

Page 64: O-Ring Considerations
5-14 O-Ring Considerations The 8242XS End Cap assemblies use a standard O-ring to provide watertight integrity to the Electronics Housing. Under normal usage, proper care, and lubrication, the O-ring should provide several years of usage. However, like the batteries, the O-ring is an inexpensive component, which is absolutely critical to the successful operation of the entire system. -
