It rivals other combination sonar/loran units costing much more in featuresand performance. The 2-9500 offers easy-to-use operation at thetouch of a button. The wide screen showsthe underwaterworki with high resolution and detail. It also displays digital depth, boat speed, surface water temperature, and distance travelled (distance log). Although the Z-9500 has many features and functions,the "soft key" menu system makes it easy to use. Above all, don't be afraid to try differentfeatures and functionson the unit. You can't hurt it by pressing buttons! Read this manual and take it with you the first few times you use your unit. It makes a great referenceshould you need it. Note: This is an "Unofficial-Preliminary Coverage Diagram". Coverage was computed using conservative estimates of station range limits, atmospheric noise, and grid geometry. MOUNTING - DISPLAY UNIT Install the Z-9500 in any convenient location,, provided there is clearance behind the unit when it is tilted for thebest viewing angle. Holes in the bracket base allow wood screw or through-bolt mounting. You may need to place a piece of plywood on the back of thin fiberglass panelsto secure themounting hardware, Makecertainthere is enough room behind the unit to attach thepower and transducercables. The smallest hole that will pass one power or transducerplug is one inch. After the hole is drilled, pass the transducer connector up through the holefirst, then pass thepower cable down through it. After the cables have been routed, fill the hole with a good marine sealingcompound. Offsetthe bracket to coverthe majorityof the hole. POWER CONNECTIONS The Z-9500 works from a twelve-volt battery system only. You can attach the power cable to an accessoryor power buss, howeverif you have problems with electrical interference, then attachthe powercable directlyto thebattery. Ifthecable is not longenough,splice#18 gauge wire onto it. Requires optional ST-TSpeed/Temperature sensor. 1 PDF compression, OCR, web-optimization with CVISION's PdfCompressor The power cable has three wires; red, white, and black. Red is the positive lead, black is negative or ground. Attachthe in-linefuse holder to the red lead as closeto thepowersource as possible. For example, if you have to extend the power cable to the battery or power buss, attach the fuse holder to the battery or power buss. This will protect both the unit and the power cable in the event of a short. The white wire is for a NMEA interface. The Z-9500sendsdata for an autopilot or other electronic navigation devices through this wire. If the white wire is notused, tape the end so that it cannot short. LORAN-C GREAT LAKES CHAIN GRI 8970 DRAFT To connect a deviceto the Z-9500's NMEA output, attach a shielded, twisted pair cable from the autopilot's NMEA intputto thewhitewire on the Z-9500's power cable. Solder the ground conductorof thetwisted pair and the shield to the black wire on the power cable. Do not connect the shield to the autopilot. See the other device's manual for more wiring instructions. TheELC-1 suppliedwith the2-9500 hasan external groundlug. This is useful if you have noise problems or if you're in an area with low signals. See page 103 for wiring instructions.

The Z9500 automatically sends NMEA information out the white wire once it acquires and "locks on" to the stations. TRANSDUCER CONNECTIONS The Z-9500has dual frequencycapability. It can operate at 50 or 192 kHz, separately, or at the sametime. The connection diagrambelow showsthepropermethodto attach thetransducersto theZ-9500. See the transducer owner's manual for transducer installation instructions. If dual frequency operation is desired, a 50 kHztransducerand the MY2 transducer adapter cable mustbe purchasedsepartately. 1. NOISE Minimize electrical noise by routing the power cable away from other possible sources of electrical interference. One of the largest noise generators is the engine's wiring hamess. For best results, keep the power, loran module, and transducer cables away from the engine wiring. Bilge pumpsand their wiringcan also radiate noise, so keepthe cables away from them, if possible. Note:This is an "UnofficialpreliminaryCoverage Diagram". Coverage was computed using conservative estimates of station range limits, atmospheric noise, and grid geometry. VHF radio antennas and cables radiate RF energy at high powerlevels. It is important to keep theZ-9500's cables awayfrom them, also. __________________________________________________________ SINGLE FREQUENCY DUAL FREQUENCY rr CONNEcTOR ON 95cc · 1' coNNEcToRON 95O · --.192kHz or5OkHz TRANSDUCER TRANSDUCER ADAPTER CABLE (MY-2) II 192kHz TRANSDUCER 11(llt4LISlk1 I 50kHz TRANSDUCER TRANSDUCER CONNECTIONS "N. -- I. ii PDF compression, OCR, web-optimization with CVISION's PdfCompressor 3 Noise typically shows on the sonar display. If interference begins at slow boat speeds and gets worse as the speed increases, then the probablecause is acoustic noise or cavitation. This noise is not electrical, but is caused by air bubbles passing over the face of the transducer. It's easy to determine if this noise is electrical or cavitation. Stop the boat, put the engine in neutral, and increase the rpm. If the noise increases, then it's electrical. If it doesn't show on the sonar's display, then the problem is cavitation. To solve this problem, the transducermust be moved out of the turbulentwater flow or adjusted so that smooth water flowsover it at all boat speeds. The Z-9500 has reversepolarity protection. No damage will occur to theunit ifthepower wiresare hooked up backwards. However, theunit will not work until thewiring is connectedproperly. INSTALLATION- ELC-1 Loran-C MODULE When choosing a mounting location, remember to install the ELC-1 where it's clear of other antennas, wires, masts, or other obstructions. A high location is preferred, however for lightning protection, the antenna shouldn'tbe the highest part oftheboat. The antennashould be mounted vertically. Makecertain it is as faraway as possible from VHF radio antennas. LORAN-C NORTH PACIFICCHAIN GRI 9990 Improper performancecan also occur if the antenna is mounted too close to metal objects such as tuna towers. Again, a location that places the Loran assemblyin the clear is 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"-24 for the whip. A ratchet mount base is most commonly used to mount the Loran to the boat. The base mounting threads are conventional 1"-14 machine thread (NOT pipe thread). This allowsthe use of standard antenna mounting hardware. Tighten all hardware securely. The cable supplied with the ELC-1 is thirty feet long. Do not cut the cable if it's too long. Instead, coil and store it out of the way. An extensioncable is available if thecable is too short. Ask your dealer or call your local service center or the Eagle Factory Customer Service departmentfor moreinformation. The ELC-1 can be attached to a swivel bracket or hollow extension mast, if desired. 4 PDF compression, OCR, web-optimization with CVISION's PdfCompressor KEYBOARD The keyboardhas keys arranged in two verticalcolumns.
