：
 Do not power on the equipment when the transducer is expose to the air. It might
cause the damage to the transducer.
 Insta the transducer according to the instruction. Do not bend, twist, pu or press
the cab e of the transducer.
 The extension cab e needs to put inside the sea termina box. The cab e of the
transducer is not a owed to touch the surface of the boat.
 Once the equipment’s power has been put into the “on” position do not switch the
computer’s power to the “off” position unti the computer is fu y booted.
 P ease make sure that the power vo tage setting has been adjusted to the standard
vo tage va ue of the ocation where the product is being used.
 Before using this product, p ease first make sure that a externa wires and power
adapters have been correct y connected. If you suspect any defects, p ease contact
your sa es agent or factory personne immediate y.
 Dust, humidity and dramatic temperature changes wi affect the usage ife of this
computer. P ease keep the machine away from these hazards.
 In c eaning the units do not use chemica detergents. Remove dust with a soft
c oth to ensure brightness.

．Transducer Installation:
Transducer is a precious front signa sensor. It must transport and insta with care, no heavy
pressure, fa off or working in the air. Painting and parasite shou d keep away from the
surface of the transducer.
The mounting ocation is very important and wi affect the measure accuracy of the
transducer direct y. It is recommended to insta it on the bi ge where the surface is smooth
and f at. Keep the transducer far away from prope er or pipe ines which generate turbu ent
water. Keep the surface of the transducer horizonta , use guide p ate to guarantee gent e water
f ows if the bi ge is not f at. Do not expose the transducer into the air under any
circumstances.
Mark and dri mounting ho es:

7
1) Ensure that ship at the horizonta position, and the hu does not ti t.
2) Ho ding the transducer bracket temp ate for the boat to mark the two mounting ho es.
Center of two ho es shou d be para e to the surface. Ensure that the bottom of the
temp ate and the distance between the ower edge of the beam is about 0 ~ 5 mm.
