the

stylus may

damaged. (See Figurel9.)

SPECIAL NOTE: The

stylus

may

damaged

if the

platen

assembly

pulled

down un-

less the

stylus

has been

moved to the back side of the

platen.

4. Pull out and down on

the

tab

at the

top

center of the

platen

assembly

expose

the

pa-

per spools. (See Figure2o.)

5. To remove the full

take-up

roll

and the

empty supply spool,

press

the two metal tabs to-

gether

on the

top

of the

platen

assembly,

and

pull

out and

down on the

paper

retainer.

(See Figure 21.)

The full take-

roll can now be

easilly

re-

moved from the

paper

core

shafts.

(See Figure 22.)

6. Pull the

empty supply

core

from the

right

side in the

same manner. Install

the

empty

core onto the

take-up

shaft.

(See Figure

23)

Align

the two notches in

the

core with the tabs on the

lower

take-up spool.

7. Slide a fresh roll of

paper

position

on the

supply

side

•

shaft on the

right

side of the

•

platen assembly.

The

paper

must

spool

off the bottom of

the roll.

(See Figure 24)

8. Draw the end of the

paper

across the face of the

platen,

around the friction

roller,

over

the

take-up

core,

and

tape

squarely

to the

take-up

core.

(See Figure 25)

Small

pieces

tape may

be stored inside

the

housing

for this

purpose.

Close the

top

of the

platen

assembly by pressing

the two

tabs

together

on the

paper

retainer and

returning

the re-

tainer back

to the

operating

position. (See

Figure26)

9. Turn the small knob at the

upper

left hand side of the

platen assembly

put

small amount of tension on

the

paper.

It should be

snug

against

the

platen. ( Figure

27)

10. Push the

platen assembly

back to its

operating position.

Be sure it

engages

the catch

inside the

top

of the case.

(See Figure2O)

11. Close the front of the case.

Latch both catches on the

top

of the case.

12. Turn the unit on. Move the

Chart

fully

clock-

wise. Watch the

paper long

enough

to be sure it is mov-

ing smoothly

and

evenly

across the

SPECIALNOTE: The stylus may be damaged if the platen assembly is pulled down unless the stylus has been moved to the back side of the platen. 4. Pull out and down on the tab at the top center of the platen assembly to expose the paper spools. (See Figure2o.) 5.

STYLUS REPLACEMENT CAUTION — High voltage is pre- sent in the electronic section when the unit is turned on.' 1. TURN THE UNIT OFF. 2. Release both catcheson the top of the case. Pull out and down on the top of the case front to expose the stylus belt. (See Figurel8.) 3. The stylus belt rides over two Figure 17 wheels located at the right edge of the platen assembly. Move the front of the belt DOWNto position the stylus at the center of the platen. 4.

Figure 28 Figure 14 ZOoM "OFF" ZERO ADJUST Occasionally, when changing the stylus or stylus belt, the zero does not print at the same place near the top of the chart paper. By rotating the BOTTOM ZOOM control counter-clockwise the zero line can be moved towards the top of the chart paper, clockwise rotation moves the zero line towards the bottom of the paper. The control has been designed so that even if the record goes off the bottom of the paper, it- can still be adjusted to print on the paper.

wheels by reversing the procedure used to removethe old one. BE SURE the fingers of the new stylus are pointed UP. 6. Close the front of the case. Latch both catches at the top of the unit. 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.

sound pulse hasto travel, the weaker it becomes. 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.

lines immediately. 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. Transmitand Print Alternate When using the MACH 1 in deep water, it may be desirable to slow the papersped down considerably.

Figure 3 BASIC OPERATION ON-OFF and SENSITIVITY Control Rotate the ON/OFF knob clockwise to turn the unit on. 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.

tional featuresthat you have programmedin. Just remember, if you have turned the lines and the scales off, and you wish to turn only the scales back on, don't turn off power to the unit or you will have both lines and scales on — Figure 38 when you turn the unit back on. Turning the unit off and then on again only works as a quick method when you only have one feature on, or all of the optional features that you wish to return to normal.

echo can be read in feet by comparing its location on the paper to the depth scale printed on the 1. 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.
