Intended Use
Raymarine HD (High Definition) Series Fishfinders are intended for
recreational fishfinding. The combined Fishfinder/Chartplotter (RC) devices
are intended for recreational fishfinding and course chartplotting. The
optional chartplotter function is intended as an aid to navigation and should
not be relied upon as a substitute for official navigation charts.
SAFETY NOTICES
This equipment must be installed and operated in accordance with the
instructions contained in this manual. Failure to do so can result in personal
injury and/or navigational inaccuracies. In particular:
1. HIGH VOLTAGE. The LCD display and digital sounder units contain
high voltages. Adjustments require specialized service procedures and tools
only available to qualified service technicians. There are no user serviceable
parts or adjustments.
The operator should never remove the unit cover or
attempt to service the equipment.
CAUTION:
Removing the transducer cable from the fishfinder display or the
DSM250 while the unit is powered on can cause sparks. Only remove the
transducer cable after power has been removed. As with any electronic
device, be sure the units are mounted where it is well ventilated and free
from gasoline fumes.
If the transducer cable is accidentally removed while the DSM250 is powered
on, remove power from the sounder module, replace the transducer cable, and
then return power to the module. As a safety feature, the DSM250 recognizes
that the transducer is connected only at power-up.
2. NAVIGATION AID. The chartplotter 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
judgements. This unit should not be relied upon as a substitute for such
prudence and judgement.
