mation on the screen. If the screen comes out normal, then
speed up your boat. Always observe the display unit during
the course. If the signal is lost or abnormal at a certain
speed, note the speed.
c- Adjust the transducer in a small scope and run the boat at
the noted speed. Observe the display unit. If the screen is
normal, go to the next step. If not, please adjust the trans-
ducer until it comes out normal. If by any means, a normal
sonar display can not be obtained, then it is necessary for
you to relocate the position of the transducer.
1.7 Final installation
a- Make sure the transducer can be completely immersed into
water and adjust the location of the template on the tran-

the boat runs at a high speed.
b- As soon as you believe you have found the best mounting
location of the transducer, release the pivot from the tem-
plate, then mark the third hold with a pencil.
c- Using a 5/32” bit, drill a hole of approximately 1” (25mm)
deep at the marked position.
d- Apply marine sealant in the three holes and hold the
template against the transom. When you are sure that the in-
stallation is completely in line with the mounting location,
tighten the three screws with an Allen wrench.
