Do not install the set in a place that exposes the CRT to direct sun
for a long time or a place whose environmental temperature can
reach 55 degree Centigrade or above. Otherwise, fire hazards or
system failure can result from such operating environment.
Do not install the set on an unstable place such as shaky or in-
clined bench. Otherwise, personal injuries can result from the
fallen or collapse set.
Environment of the set must be free of magnetism field. Failure to
observe this precaution may disturb the screen display colors of
water depths or of alarms, thus causing accidents.
Do not close the ventilation port of the set. Otherwise, fire haz-
ards or system failure can result from the heated set.
Reasonable care must be exercised for the routing of piezoelectric
transducer, power cable and grounding cable. Otherwise, the
echo sounder can adversely effect other equipment or vice versa.
When the echo sounder installation is complete, turn on power for
all other equipment to make sure that they are free of troubles.
