2. Clean and dry both the selected area and the face of the
transducer with a weak solvent to remove any dust,
grease or oil.
3. If the hull temperature is above 15ºC (60ºF), mix the
epoxy until the color is uniform. Do not proceed if the hull
temperature is below 15ºC (60ºF) because the cure
time will be greatly extended.
4. Apply a generous amount of epoxy to the center of the
face of the transducer (side opposite from the cable).
5. Press the transducer face onto the hull with a twisting
motion to expel all air bubbles. (If the hull is slanted, tem-
porarily secure the transducer in place with duct tape.)
The adhesive is cured in 24 hours at 21ºC (70ºF). The
lower the temperature the longer the cure time.
6. After the adhesive has cured, route the cable to the
transmitter being careful not to tear the cable jacket
when passing it through the bulkhead and other parts of
the boat. To reduce electrical interference, separate the
transducer cable from other electrical wiring and sources
of interference. To prevent damage, cut the transducer
cable to the desired length.
NOTE!!!!
The working time of the epoxy is only 5 minutes.

FIGURE 10C
If the hull surface is not smooth, grind it with a disc
sander. Partially fill a thin plastic bag with water, place the
transducer inside and close it tightly with a tie wrap. Wet
the surface of the hull and press the transducer face
against it through the bag (Figure 20 C).
Selecting the Adhesive
Hard adhesives, transmit sound best, but winter tempera-
ture extremes and flexing on trailer rollers can cause it to
delaminate. However, soft adhesives absorb sound. To
compromise, use a viscous slow-cure epoxy or a fairly
rigid, one part adhesive sealant. In cold climates, a one-
part polyurethane adhesive, such as Boat-Life’s Life Seal‚
may be best. Do not use “5 minute” epoxies because they
are generally brittle. RTV (silicone) adhesives are not rec-
ommended because most of the sound energy is lost.
Installation
1. All surfaces to be bonded must be smooth, clean
and dry. If the surface is rough, use a disk sander to
smooth an area a little larger in diameter than the
length of the transducer.
CAUTION!!!!
Always wear safety goggles and a dust
mask when sanding.

Warning: Changes or modifications to this unit not
expressly approved by the party responsible for com -
pliance could void the user ’s authority to operate the
equipment.
This device complies with part 15 of the FCC rules.
Operation is subject to the following two conditions: 1)
This device may not cause harmful interference and 2) This
device must accept any interference received, including
interference that may cause undesired operation.

Testing the Depth Sounder
Establish a performance baseline by operating the depth
sounder with the transducer directly in the water. The results
of this test are used as a basis of comparison to determine
the best in-hull location for the transducer.
1. Anchor the boat in at least 15 m
(50') of water. (If you have a
digital unit, conduct this test in
water as deep as that for which
the depth sounder is rated.)
2. Tape the transducer to a pole,
cable side up, and hold it over
the side of the boat (Figure 19).
The cable side must be parallel
to the surface of the water.
3. Observe the depth sounder
performance. Record the
depth reading.
Testing at the Selected Location
While the boat is anchored, use one of the methods below to
test the depth sounder with the transducer at the selected
location. If the test readings differ markedly from the base-
line or there is almost no reading, you will need to find anoth-
er location. If the two readings are reasonably similar, mark
the spot on the hull and proceed with the installation.

IMPORTANT!!!!
Please read the instructions completely
before proceeding with the installation.
P23 Transom/In-Hull Transducer
Applications
• Powerboats with outboard, inboard / out-
board, or jetdrives. Not recommended for
use with large or twin screw inboard motors.
• Allows sound beam to be oriented vertically
on hulls with a deadrise angle of up to 30°.
• Adjusts to transom angles from 3-20°.
Thru-Hull Transducer Applications
•Inboard boats, sailboats, wooden boats, or
metal hulled boats.
If, after completely reviewing the transducer
installation instructions, you find that the sup-
plied transducer is not appropriate for your ves-
sel, please contact NorCross at 888-667-2767, or
visit us on the internet at www.norcrossma-
rine.com for exchange information. You may
exchange your new and unused transducer for
another type, but keep in mind that some trans-
ducers may have additional costs.
4

Never use adhesive to fill
gaps between the trans-
ducer and the hull since
this will greatly reduce
performance (Figure 18).
Headroom
Choose a location with enough headroom inside the boat to
complete the installation.
Hull material
Since the hull absorbs acoustic energy, transmitting through
the hull reduces the transducers performance. Fiberglass
hulls are often reinforced in places for added strength. These
cored areas contain balsa wood or structural foam which are
poor sound conductors. To achieve optimal performance,
find a location where the hull laminate is solid (not cored).

Do not use
RTV sealants
or adhesives
to fill gaps.

SETTING UP THE TRANSMITTER AND RECEIVER
The ML100DR and ML100R wireless displays utilize a
code learning function which allows the transmitter to
exchange its unique operating code with the receiver.
This code learning feature makes each wireless depth
sounder unique, therefore eliminating the chance of your
system interfering with a nearby vessels.

1. Upon applying power to the transmitter and receiver,
place the display over the transmitter. Refer to Figure
1 for proper alignment.
IMPORTANT!!!!
Before Installing the ML100DR and ML100R, it will be
necessary to match the receiver to the transmitter.
This can be completed before installing the system
on the vessel by simply applying power to the trans -
mitter and receiver and following steps 1 thru 3. The
receiver retains this unique code in its memory, and
will only need to be relearned if the channel on the
transmitter is changed.

2. While the code is being gener-
ated the display will flash
“LEA” to indicate that it is in
LEARN mode. You may need
to slowly move the display
around the surface of the trans-
mitter until “LEA” is indicated
on the display.
3. Once “LEA” stops flashing the Code Learning process
is complete and you can now proceed with installation.
NOTE!!!!
If the depth sounder displays “E” constantly during
usage, the setup procedures on page 5 will have to be
repeated.
INSTALLING THE TRANSMITTER (ML100T)
IMPORTANT!!!!
Please read the instructions completely
before proceeding with the installation.
*For optimal performance avoid installing the trans -
mitter in engine compartments where sound sup -
pression insulation may reduce the range.
*If the deck of your boat is constructed from metal
(aluminum, steel, etc) the transmitter will need to
be installed above deck.

IMPORTANT!!!!
On most vessels the Transmitter (ML100T) can be mount -
ed in a variety of locations. It is suggested that you test
the installation location first by temporarily installing the
display and transmitter. Consistent, steady depth read -
ings on the display indicates interference free operation.
A display reading of “E--” indicates reduced range condi -
tions and may be corrected by moving the transmitter.
* The mounting location of choice must be above
the waterline of the vessel, and free from water
spray, and/or water submersion.
* A mounting location that produces the furthest
range should prove to be the optimal location.
* Do not mount the Transmitter within 12 inches of
any magnetic producing devices (compass, auto
pilot control, etc.)

OPERATING THE WIRELESS DISPLAYS
The depth sounder’s auto-ranging, auto-sensitivity fea-
tures means that you never have to worry about adjust-
ments. Simply turn the power on, and your ready to go.
The transducer emits sound signals that travel through
water, and the depth sounder then
calculates the amount of time that
elapsed while the signal traveled
down to the bottom and returned
back to the transducer. This time is
calculated and is displayed as a
depth reading. Extremely dirty
water, very soft bottom, high speeds, deep water, or a
combination of the above will result in incomplete or inac-
curate readings. Under these conditions variable readings
or “- - -” (Figure 9) will be displayed.
If the wireless display is not
receiving a signal from the trans-
mitter “E--” will appear in the
LCD (Figure 10). If this occurs
refer to the troubleshooting
guide for more information.
The display will show the current
depth upon power up. Both the
ML100R and ML100DR displays
will read “E” (Figure 11) if the
stored code does not match the
transmitters. If this occurs, the
setup procedures on page 5 will
have to be repeated.
