products are, prior to packing and shipping, subjected to
comprehensive test and quality assurance programs. However, if a
fault arises with your RayData, the following table will help you to identify
the probable cause and provide the most likely cure.

Operation in Very Shallow Water
The Raydata is designed to operate down to a minimum depth of 2.8
feet below the transducer. Below this value, multiple echoes can
sometimes be received, resulting in deeper depth readings than the
actual depth.
7.3 Absent Data
If a required data value is not received via the SeaTalk bus or NMEA
connection for 30 seconds, then the displays that require the data
