8.Draw the end of the paper across the face ofthe platen, around the frictionroller, over

and tape it sciuarely to the take-upcore. (See Figure 30.) Small pieces

of tape may be stored inside the housing for this purpose.

Close the top ofthe platen assembly by pressing thetwo

tabs together on the paper

retainer and returning the re- tainer back to the operating

position. (See Figure 31.)

9. Turn the small knobatthe upperleft hand side of the

platen assembly to put a small amountoftension on

the paper. It shouldbe snug against the platen. (Figure 32.)

10.Push the platen assembly

backto its operating position. Be sure it engages the catch inside the top of the case.

STYLUSREPLACEMENT

CAUTION — High voltage is pre- sent in the electronic section

when the unit is turned on.

1.TURNTHE UNIT OFF.

2.Release both catches on the

top ofthe case. Pull out and down on the top of the case front to expose the stylus belt. (See Figure25.)

3.The stylusbelt ridesover two

wheelslocated at the right edge ofthe platen assembly. Move the front of the belt

DOWN to position the stylus at the centerof the platen.

4.Hold the stylus belt stationary with one finger, and remove

the old stylusby starting at its left edge and moving it out from underthe tabs on the sty- lus holder.

5.Before installing the new sty- lus, be sure it is bent properly by comparing it to Figure 33.

6.Referto Figure 34to be sure the newstylus is positioned

correctly underthe tabs on the holder. Be sure it moves freely in the two slots. If not, bend

the stylusaway fromthe edge it is rubbing on until it does move freely.

7. Afterinstalling, if the stylus

won't all the	way	down
print

the paperas shown in Fig-

ure 35,bend the right leg down so that more pressure is ex-

ertedagainst the stainless steelplate. If it still does not

print all the way, bend the left

leg down more (butnot so far that it digs into the paper).

8.Close the frontofthe case.

Latch both catches on the top ofthe case.

er fish arches at low speeds and keeps high speed information from

being compressed. The paper speed should be turned down

when usingthe unit in deep water. This will prevent gaps from ap-

pearing in the record. In fact, the

microcomputer will automatically slowthe maximum speed of the

chart paperwhenoperating in deep water. The chart below gives the points wherethe maximum

,speed of the paperis slowed. RANGE PAPER SPEED

10,-hO'	Fastest Paper
120'-490'	Speed
	Medium Fast
500'-790'	Paper Speed
	Medium Slow
800'& Below	Paper Speed
	Slowest Paper
	Speed

The chart paper may be slowed evenfurther by adjusting the pa-

per speed control. Remember, if gaps in the record appear, turn the

paperspeed down until a solid record is achieved. The paper

speed may also be slowed when not looking forfish or to simply

conserve paper. For more informa- tion about saving paper, readthe AlternateTransmit and Print func-

tion in the Advanced Operation section.

GRAYLINE CONTROL

The GRAYLINE function can be ' usedto outline the bottom contour

which mightotherwise be hidden beneath trees and brush; it can also give clues to the composition of the bottom.A hardbottomre-

turns a very strong signal causing

awide gray line. A soft, muddy or weedy bottomreturns a weaker

signal whichis emphasized with a narrowgray line. Do not advance

the control too far or it will gray

RANGE

The rangefunction utilizes the

keyboard to select any range be- tween0-10'and 2540'-2550'.

Please read this section carefully to get the mostout of your Z-15's

range capabilities.

Lower Limit

When ybu first turn on the Z-15, the range will be 0-60 feet.

(SeeFigurela.)

To change to a deeper range, simplypress the desired depth on the keyboard, and then press the LOWER LIMIT key..
