•

Raymarine specified cables are used. Cutting and rejoining these cables 
can compromise EMC performance and must be avoided unless doing so 
is detailed in the installation manual.

•

If a suppression ferrite is attached to a cable, this ferrite should not be 
removed. If the ferrite needs to be removed during installation it must be 
reassembled in the same position.

1. PRODUCT INSTALLATION. This equipment must be installed and 
operated in accordance with the instructions contained in this handbook. 
Failure to do so could result in poor product performance, personal injury 
and/or damage to your boat. 

2. HIGH VOLTAGE. The display unit, transducer cable, and transducer 
contain high voltages. Adjustments require specialized service procedures 
and tools only available to qualified service technicians - there are no user 
serviceable parts or adjustments. 

3. NAVIGATION AID. This unit is only an aid to navigation. Its accuracy 
can be affected by many factors, including equipment failure or defects, 
environmental conditions, and improper handling or use. It is the user’s 
responsibility to exercise common prudence and navigational judgments. 
This fishfinder should not be relied upon as a substitute for such prudence 
and judgment.

4. ULTRASONIC ENERGY. The transducer transmits high frequency 
energy while in use. The unit should be turned off when swimmers or divers 
are in close proximity to the transducer. (There is a lack of scientifically 
sound standards or guidelines for exposure levels and limits to ultrasound. 
This notice is precautionary only.)
