INTRODUCTION

The Z-9500 represents one of the best values in sportfishing sonar today. It rivals othercombination sonar/loran unitscostingmuch more in featuresandperformance. The2-9500offers easy-to-use operation at thetouchofabutton. The widescreenshowsthe underwaterworki

with high resolution and detail. It also displays digital depth, boat speed, surface watertemperature, and distance travelled (distance

log).

Although the Z-9500has many features and functions,the "soft key" menu systemmakes it easy to use. Above all, don'tbe afraid to try differentfeatures and functionsonthe unit. You can'thurt it by press- ing buttons!

Readthis manual andtake it with you the first few times you use your unit. It makes agreatreferenceshould you need it.

MOUNTING - DISPLAY UNIT

Install the Z-9500 in any convenient location,,providedthere is clear- ancebehind the unit when it is tiltedforthebest viewing angle. Holes in the bracket baseallowwood screw or through-bolt mounting. You may need to place a piece of plywood on the back of thin fiberglass panelstosecure themounting hardware, Makecertainthere is enough roombehind theunit to attach thepowerandtransducercables.

The smallest hole that will pass one power or transducerplug is one inch. After the hole is drilled, pass the transducer connector up throughthe holefirst, then passthepowercabledownthrough it.

After the cables have been routed, fill the hole with a good marine sealingcompound. Offsetthe bracket to coverthe majorityofthe hole.

POWER CONNECTIONS

The Z-9500works from a twelve-volt battery system only. You can attach the power cableto an accessoryor powerbuss, howeverif you haveproblems with electrical interference, then attachthe powercable

directlytothebattery. Ifthecableis not longenough,splice#18 gauge wireonto it.

Requires optional ST-TSpeed/Temperaturesensor.

PDF compression, OCR, web-optimization with CVISION's PdfCompresso

The power cable has three wires; red,white, and black. Red is the positivelead, black is negative or ground. Attachthe in-linefuse holder

tothe redlead as closetothepowersource as possible. For example,

if you have to extendthe power cable to the battery or power buss, attach the fuse holderto the batteryor powerbuss. This will protect

both the unit and the powercable in the eventof a short. The white wireis fora NMEA interface. TheZ-9500sendsdata for an autopilot

or other electronicnavigation devices through this wire. If the white wireis notused,tape the end so that it cannot short.

Note:This is an "UnofficialpreliminaryCoverage Diagram". Coverage wascomputed usingconservative estimates of station range limits,

atmospheric noise, and grid geometry.

No otheradjustments are required oncethe cableis connected.TheZ-

9500 automatically sendsNMEA information outthe white wireonce it acquires and "locks on"tothe stations.

TRANSDUCER CONNECTIONS

TheZ-9500has dual frequencycapability. Itcan operate at50 or 192 kHz, separately, or at the sametime. The connectiondiagrambelow

1.showsthepropermethodto attach thetransducerstotheZ-9500. See the transducer owner'smanual fortransducerinstallation instructions.

Ifdual frequency operation isdesired, a 50 kHztransducerandthe MY- 2 transducer adapter cablemustbepurchasedsepartately.

NOISE

Minimize electrical noiseby routing the power cable away from other possible sources of electrical interference. One of the largest noise

generators is the engine'swiring hamess. For best results, keepthe power, loran module, and transducercables away from the engine wiring. Bilge pumpsandtheirwiringcan alsoradiatenoise,so keepthe cables awayfromthem, ifpossible.

VHFradio antennas and cables radiate RF energyat high powerlevels.

It is important tokeeptheZ-9500'scables awayfrom them, also.

The Z-9500 has reversepolarityprotection. No damage will occur to theunit ifthepowerwiresarehooked upbackwards. However, theunit will notwork until thewiring isconnectedproperly.

INSTALLATION- ELC-1 Loran-C MODULE

When choosinga mounting location, remember to install the ELC-1 where it'sclear of other antennas, wires, masts, or otherobstructions.

A high locationis preferred, however for lightning protection, the an- tenna shouldn'tbethe highest partoftheboat. Theantennashould be mounted vertically. Makecertain itis as farawayas possible fromVHF

radio antennas.

Improperperformancecan also occur if the antenna is mounted too close to metal objects such as tuna towers. Again, a locationthat

places the Loranassemblyin theclearis preferable to one that is high and obstructed.

You must purchase an eight foot stainless steel or fiberglass whip antenna. The threads are standard 3/8"-24for the whip. A ratchet

mount base is most commonly usedto mountthe Loranto the boat. The base mountingthreads are conventional 1"-14 machine thread

(NOTpipe thread). This allowsthe use of standard antenna mounting hardware. Tighten all hardware securely.

The cable suppliedwith the ELC-1 is thirty feet long. Do not cut the coil and store it out of the way. An

ifthecableis too short. Ask yourdealer or call your local servicecenter or the Eagle Factory Customer Service departmentfor moreinformation.

The ELC-1 can be attachedto a swivel bracket or hollow extension mast,ifdesired.

Toturn Automatic off, simplypressthe AUTO key. The letters "Man" appear, indicating the unit is in the manual mode. To turn Automatic on, press the AUTOkey again.

SENSITIVITY

Thesensitivity key on theZ-9500controls the abilityofthe unit to pick up echoes. A low sensitivity level excludes muchof the bottom information, fish signals, and other target information. High sensitivity levels enable you to see this detail,but it can also clutter the screen with noise. Typically, the best sensitivity level shows a good solid bottomsignalwith Grayline®and somesurface clutter.

When the Z-9500is inthe Automatic mode,the sensitivityis automati- callyadjusted tokeepa solidbottomsignaldisplayed,plus a little more.

Thisgives itthecapabilityto showfish and otherdetail.

To adjust the sensitivity, pressthe SENS key. The sensitivity adjust menu appears on the left side of the screen. The Graylineadjust menu is immediately beneathit. (Seethe screen atthe topofthe next

It you have two signals of equal size, one with gray and the other without, then the target with gray is the stronger signal. This helps distinguish weedsfromtrees onthe bottom, or fish from structure.

GRAYLINE is adjustable. Since GRAYLINE shows the differencebe-

tween strong and weak signals, adjusting Sensitivity may require a different GRAYLINE level, also. The level chosen by the Z-9500 at

To adjust GRAYLINE, press the SENS key. The sensitivity menu appears inthe upperleft sideofthe display, whilethe GRAYLINElabel appears immediately beneath it. Next, press the key adjacent to the
