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 15 C (60 F), mix the epoxy until the color is uniform. Do not proceed if the hull temperature is below 15 C (60 F) because the cure time will be greatly extended. The working time of the epoxy is only 5 minutes. NOTE!!!!

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 21 C (70 F). 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. 36 TABLE OF CONTENTS Transducer Selection . Transducer Installation . Setting up the Transmitter and Receiver .

**Included within the ML100TR System. Additional Display can be added at any time by following the setup instructions on page 5. 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-Lifes 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 CAUTION!!!!

Always wear safety goggles and a dust mask when sanding. ML100T Wireless Depth Sounder Transmitter

**Included within the ML100TR and ML100DTR Systems. Both the ML100R and ML100DR wireless displays require the transmitter to function as a depth sounder display. 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. 2 35 Figure 20 A B C CAUTION!!!!

Always wear safety goggles and a dust mask when sanding. FIGURE 10A This method is practical if the transducer will be located near the stern and the boat has a low deadrise angle. Clean away any large build-up of grease and / or dirt. Place the transducer against the hull and allow bilge water to cover the surface where they touch (see Figure 20 A). FIGURE 10B If the hull surface is not smooth, grind it with a disc sander. Coat the face of the transducer with petroleum jelly and press it against the hull with a twisting motion

(see Figure 20 B). Warning: Changes or modifications to this unit not expressly approved by the party responsible for com pliance could void the user equipment. s authority to operate the

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. 34 3 TRANSDUCER SELECTION Testing the Depth Sounder 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 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. Figure 19 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 P23 Transom/In-

Hull Transducer 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. Thru-Hull Transducer 33 Figure 18 Never use adhesive to fill gaps between the trans-

ducer and the hull since this will greatly reduce performance (Figure 18). Do not use RTV sealants or adhesives to fill gaps. NO Headroom TRANSDUCER INSTALLATION Transom Mount Transducer Installation

(P23 Tr a n s d u c e r ) Please follow the supplementary instruction provided in the transducer hardware package. Thru-Hull Transducer Installation

(P6 Transducer) Please follow the supplementary instruction provided in the transducer hardware package. In-Hull Transducer Installation

(P23 or P6 Transducer) Choose a location with enough headroom inside the boat to complete the installation. Please follow the supplementary instructions provided in Appendix A of this manual. 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). 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. 32 5 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. 1. Upon applying power to the transmitter and receiver, place the display over the transmitter. Refer to Figure 1 for proper alignment. Figure 1 Figure 17 Outboard Inboard/Outboard Inboard Sailboat Display ML100R Transmitter ML100DR Display Transmitter 6 31 L o c at i o n Consult the boat manufacturer for the best in-hull transduc-

er placement. If this information is unavailable, follow the guidelines below and see Figure . Outboard powerboats - Install as far aft as is practical Inboard / outboard powerboats - Install close to the engine(s) Inboard powerboats - Install forward of the propeller(s) and shaft(s) Sailboats - Install near the centerline of the hull and for-

ward of the leading edge of the keel Deadrise Angle Be sure the deadrise angle is less than 10

(see Figure 16 ) Figure 16 YES NO 30 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. 7

* 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.) 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. Wiring of the Transducer Cable Refer to the following directions for connecting the trans-

ducer cable to the Transmitter (ML100T) (see Figure 2). 1. Connect the blue wire from the transmitter, to the blue wire on the transducer cable. Appendix A IN-HULL TRANSDUCER INSTALLATION INSTRUCTIONS IMPORTANT!!!!

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 dirt y 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 tro u b l e s h o o t i n g 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.
