[. . . ] (See Figure 23) Align the two notches in the core with the tabs on the lower take-up spool. Slide a fresh roll of paper in position on the supplyside shaft on the right side of the platen assembly. Draw the end of the paper across the face of the platen, around the friction roller, over thetake-upcore, and tape it squarely to the take-up core. (See Figure 25) Small pieces of tape may be stored inside the housing for this purpose. [. . . ] 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. 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. 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 use oily cloths, strong solvents, Symptom or abrasive cleansers. TROUBLESHOOTING SECTION Recorded marks are very heavy; paper is torn by stylus. In other words, if gaps appear in the record, turn the paper speed down until a solid record is achieved.

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. 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. 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. 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. Since the stylus only prints every other revolution, the recorded information is not squeezed together into a very small area. Also, the scale numbers are spread out more, so they are more legible. [. . . ] INTRODUCTION Small boat sonar systems are routinely used to measure water depth, examine bottom contours, and locatefish. The Eagle MACH 1 recordergoes far beyond the ordinary in displaying these objects, plus many more such as schools of baitfish, algae and plankton, thermoclines, individual fish closer than six inches apart, and much more. These features combine to make the MACH 1 a superiorgraph recorderfor today's sportfishing echo can be read in feet by comparing its location on the paper to the depth scale printed on the paper. - A constant speed motor drives the papergraph. (The paper is treated so that the stylus will burn it to leave a permanent black mark. ) During one revolution of a 1::: Figure 40 RANGE: 60 FEET ZOOM: OFF SENSITIVITY: 314 SUPPRESSOR: MINIMUM the stylus belt, a very narrow mark will be made by the flexible stylus, but the paper will move a small amount before the next revolution.
