Hold the stylus belt stationary with one finger, and remove the old stylus by starting at its left edge and moving it out from underthe tabs on the stylus holder. 5. Before installing the new stylus, be sure it is bent properly by camparing it to Figure 28. Figure 17 EAGLE is that it can record individual fish with a characteristic arched mark that separates them from their stationary surroundings. The reason for this is shown below. The distance to a fish when it moves into the sonar's cone of sound is shown as "A" in Figurel6. When the fish has moved to the centerof the cone, thedistanceto it will be shorter, (line "B"), and as it moves out of thecone, the distance will increase again as shown in line "C". If a partial arch occurs most of the time on your unit (the mark curves up, but does not curve back down or vice-versa), it is because the transducer is not aimed straight down. Sharp, well-defined signatures will occur most often when the Sensitivity knob is set at the ¾ point, or higher. (See "A", Figurel7). Remember, too, that there must be some movement between the fish and boat to develop the arched mark. of a warm and cool layer of water and thicknessof the thermocline can vary with the season or time of day.

If not, bend the stylus away from the edge it is rubbing on until it does move freely. 7. After installing, if the stylus won't print all, the way down the paper as shown in Figure3O, bend the right leg down so that more pressure is exerted againstthe stainless steel plate. If it still does not print all the way, bend the left leg down more (but not so far that it digs into the paper). 8. Close the front of the case.

All electrical connections should be checked periodically and cleaned as necessary. The face of the transducer, if mounted on the transomshould be washed periodically with mild soapy water to remove any accumulated rod grime or oily film. This is essential to have good contact between the transducer and the water. Periodically, the rubber roller on the paper drive should be cleaned with a cloth dampened with alcohol, to improvethe friction on the drive shaft. DO SECTION Do carry a spare fuse, stylUs belt, and roll of paper. Do use the empty cardboardcore take-up post. Q Figure 11 p.r r I GRAYLINE "OFF" Figure 12 RANGE GRAYLINE "ON" MAINTENANCE NOTE: The stylus may be damaged if it is in front of the platen when the platen assemblyis pulled down. Always move the stylus to the back side of the platen when changing the paper rolls. Remember to move the belt down to remove the stylus. Black carbon dust is created during the recording process. Use a soft, oil-free rag to clean the viewing door and metal platen behind the paper. Low pressure compressed air may be used to blow dust out of the case and away from moving parts if the air per speed may also be slowed when not looking for fish or to simplyconserve paper. GRAYLINE CONTROL This control determines the depth scale displayed on the chart paper. (See Figure 13) BOTtOM ZOOM By pulling out the knob, the feature allows you to "Zoom in" on the lower half of the range being displayed on the graph. In other words, with the Range control set to the 60 foot range, and the Bottom Zoom control pushed in (OFF), the scale printed on the chart paperwill be 0 to 60 feet. (See Figure 14.) With the Bottom Zoom control pulled out (ON), the scale will be 30 to 60 feet. This allows you to double the size of anytarget or feature in the lower half of any depth range. (Figure 15.)

By broadening the pulsewidth, in essence, a larger signal is transmitted and it is easier for the receiver to detect it. For this reason, the micro-computer in the MACH 1 automatically increases the initial pulse width of the unit as deeper ranges are selected by the operator. NOTE: Initial pulse width is the pulse width of the unit when the Suppressor control is turned to minimum. INITIAL TRANSMIT PULSE WIDTH (micro-seconds) 110 150 the range control is set to 300 feet, and the Suppressor control is rotated to the maximum clockwise position, thetransmitter pulse width would be 1100 microseconds. (300 initial pIus 800 equals 1100 micro-seconds.) Paper Speed Control This knob adjuststhe speed of thechart paper. For good detailed graphs,in shallowto medium depths, turn the paper speed control up to at least ¾ when trolling. For best details,turn it up to maximum. This will show proper fish arches at low speeds and keeps high speed information from being compressed. The paper speed should be turned down when using the unit in deep water. This will prevent gaps from appearing in the record. In fact, the microcomputer will automatically slow the maximum speed of the chart paper when operating in deep water. The chart below gives the points where the maximum speed of the paper is slowed. the take-upcore. Don't rotatethe stylus belt up. Don't use oily cloths, strong solvents, Symptom or abrasive cleansers. TROUBLESHOOTING SECTION Recorded marks are very heavy; paper is torn by stylus. What To Do Bend the stylusslightly to reduce pressure on paper. Symptom On/Off switch is "ON", but the stylus and paperdon't move. What To Do Check fuse; check connections at battery for tightness and corrosion. VI ADVANCED OPERATION The EAGLE MACH 1 takes advantage of the micro-processor's power, giving you optionsthat allows it to outperform the vast majority of graph recorders in the sportfishing field. To use the functions in this sectiontwo controls must be used simultaneously. We urge you to read this section carefullyto take advantage of the superiorperformance of the EAGLEMACNi. Lines When the unit is first turned on, depth lines are printed automatically on the paper. If you desire to turn the lines off, rotate the range control to 20 feet, holdthe marker switch 'ON", and rotate the range control to the 10 feet position. The marker switch must be "ON" during the switch from 20 to 10 feet. The MACH 1 will stop printing the Symptom On/Off switch is "ON", have zero mark, but no echoes or bottom signal.

Turn the range control back to your original depth setting. To turn the lines back on, simply reverse the procedure by turning the range control to 10 feet, hold the marker switch "ON", and rotate the rnge control to the 20 feet position. Lines will be printed on the paper. Return the range control to the desired depth setting. Scale The numbers that indicate the depth or scale may be deleted if desired. Rotate the range control to the 60 feet position, hold the marker control "ON", and turn the range control to the 40 feet position. The depth scale will no longer be printed. The range control now may be turned to the desired depth setting. To turn the depth scale back on, rotate the range control to 40 feet, hold the marker switch "ON", and rotate the range control back to the 60 feet position. Remember, the marker switch must be on during the period of time that the range control is switched. Return the range control to the desired depth setting. Transmitand Print Alternate When using the MACH 1 in deep water, it may be desirable to slow the papersped down considerably. However, when doing so, you may get 'over print" or very dark, heavy printing over an area that is difficult to read. Much detail can be lost due to this. An available feature is the Transmit and Print Alternate function which, when activated, triggers the transmitter and causesthe stylusto print every other revolution instead of every revolution. This accomplishes three things: 1. Since the stylus only prints every other revolution, the recorded information is not squeezed together into a very small area. This allows better records at slower paper speeds. Also, the scale numbers are spread out more, so they are more legible. 2. Prevents the possibility of "wrap around". This is the undesirable occurrence of the second or third bottom echo printed on the paper at the top or middle of the page. Many timesthis can interfere with fish or othertargets that you wish to see. Suppressor Control The Suppressor Control is used to reduce interference from noise. Noise, in electronic terms, is any undesired signal. It can be caused by an electrical source, (such as the engine's ignition system), or by air bubbles in disturbed water which is called cavitation noise. In both cases, the noise could produceunwanted marks on the paper. (See Figure 7). Fortunately, noise ability to separate fish from the bottom or from other fish will be decreased. (See Figure 9). Therefore, the lowerthe suppression setting, the better. Advance the knob setting only as far as necessary to remove the erratic, unwanted noise marks. Most of the time at low or trolling speeds, no suppression will be needed. However, it is helpful sometimes to have longer pulse widths when noise is not a concern. When us- -- --r HO ---- --________ -- P .-1 EQ - :..çj--TT1: Iff...!J'1!Ijii - ------ -------------------EHIL Figure 6 pulses are relatively short in time compared to real sonar signals.

The Sensitivity knob works much like the volume control on a radio, that is, weaker signals will be detected with highersettingsof the knob. When cruising, or at other times when justsimple bottom-contour information is desired, the Sensitivity setting can be low. In deep water or over soft, muddy bottoms which produce weak echoes, the setting will haveto be higher. When high Sensitivitysettings are used, a second bottom echowill appear. This is normal and is caused by the returning signal reflectingoff the surface of the water, making a second trip to the bottom and back. When detailed information about brush piles, individual fish or the thermoclineis desired, the Sensitivity knob should be set approximately to the ¾ point. Refer to the illustration belowto see what effect the Sensitivity setting has on the recorded information. Recording individual fish with an "arched" signaturecan usually be accomplished at trolling speeds with the Sensitivityknob at the ¾ point, or higher. Referto the section "ArchedSignatures" for more information about this important function of your recorder. n 3. Reduces the reverberation effect. This happens mainly on lower frequency units, although it does sometimes show up on high frequency graphs. To use the Transmit and Print Alternatefunction, turn the range control to 100 feet. Next, hold down the marker switch and turn the range control to 80 feet. Now release the marker switch. Return the range control to your original setting. The MACH 1 will now be in the Transmit and Print Alternatemode. Remember, the marker control must be "ON" dur- ing the period of time that the range control is turned from 100 to 80 feet. To return the MACH 1 to normal operation, simply reverse the operation by turning the range control to 80 feet, hold the marker switch "ON", rotate the range control to100 feet, and release the marker switch. NOTE: A simpleway to return any of the optional featuresback to normal operation is to turn the sensitivity control to the "OFF" position and then turn it back "ON".

A service representative will be happy to help you. INSTALLATION Mounting -- The depth soundermay be installed in any convenient area, provided the unit can be tilted for the best viewing angle. Holes in the bracket allow wood screw or thru bolt mounting. A wood stiffener may be required on the back of thin fiberglasspanelsto support the unit. If the desired location is closer than 18" to a magnetic compass, a trial run should be made with the unit in operation to be sure that the compass readings are not affected. POWER CONNECTIONS 12 volt DC power for the sonar unit should be supplied from the boat's 12 volt DC electrical system. The power cable may be attached to an accessoryor power buss, but if you have problems with electrical interference, the cable should be attacheddirectly to the battery. If a longer cable is required, use ordinary #18 lamp cord available at any hardware or electronic Figure 38 RANGE: 60 FEET ZOOM: OFF SENSITIVITY: 1/2 SUPPRESSOR: MINIMUM PAPER SPEED: 3/4 GRAYLINE: MINIMUM p I I supply store. Splices should be soldered. If this can't be done, use crimp type splices. Tape all connections with electrical tape. An in-line fuse holder with fuse is supplied with the EAGLE graph. Be certain to install this fuse holder as close to the power source as possible. This will protect both the sonar unit and the power cable in the event a short occurs. Crimp connectorsare supplied to attach the fuse holder to the powercable. The red wire in the power cable is the positive conductor. The black wire is the ground or negative conductor. The graph is protected from accidental polarity reversals and no damage will occur if the wires are reversed. However, the unit will not operate until the proper polarity is applied.
