LORAN-C NORTH CENTRAL U.S.
INTRODUCTION The Z-9500 represents one of the best values in sportfishing sonar today. 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).
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.
No other adjustments are required oncethe cable is connected. The Z9500 automatically sends NMEA information out the white wire once it acquires and "locks on" to the stations. TRANSDUCER CONNECTIONS 1. 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.
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.
KEYBOARD The keyboardhas keys arranged in two verticalcolumns. The keys in the left column are used for loran selections. The keys in the right column pertain to the basic sonar functions. The MENU key in the bottom right cornerof the keyboard activates thefirst menu page. SONAR- This switches the unit from loran to sonar operation. SENS- Use this to adjust thesonar's sensitivityand Grayline! RANGE- This key lets you adjust the sonar'sdepth range.
PLOT - This enables the Iorans plotter function. WAYPOINT SAVE - This feature gives you more waypoint saving options. WAYPOINTRECALL - This key is used to recall waypoints from memory. LORAN-C ICELANDIC CHAIN GRI 9980 OFF - Press and HOLD the Off key to turn theZ-9500off. DISPLAY - General The lights are turned on for approximately ten seconds when the Z9500 is first turned on. A menu appears at the same time on the left side of the screen. This is the Light menu.
When the Z-9500is firstturned on, the displaywill appearsimilarto the one on thepreviouspage. The digital bottom depth is displayed in the upper left corner of the screen. The word "AUTO" in the upper center of the display indicates the sonar's automatic feature is on. A small note symbol next to the "AUTO" indicator means the alarm speaker is enabled.

DIGITAL DEPTH DISPLAY WhentheZ-9500is turnedon for thefirst time,the digitaldepth display is locatedat thetop left cornerof thescreen. This display comesfrom a separate digital sonar built into the Z-9500. It displays only the bottom depth. If it losesthe bottom,the last known depth will flash on thedisplay. Whenthedigitalfinds the bottom, it automatically displays the bottomdepth. The digital depth function has a number of featuresand options that are accessed throughthe Digital Display menu.

The Z-9500may havetrouble finding the third cycle if you operate the unit under high noise conditions, or at the extreme limit of its range. You can force the unit to jump to the proper cycle.
DEPTH LINES TheZ-9500can print depth lines across thescreen to make it easierfor you to determine a target'sdepth.

N For example, lets say the bottom of the rudder on an inboard boat is the lowest part of the boat. After measuring, you discover it's 4 feet deeperthan the face of thetransducer. Turn the Z-9500 on and press the MENU key. Next, pressthe key nextto the"More" label two times. Now press the key adjacent to the "Keel Offset" label. Finally, press the key adjacent tothe "Neg. Keel Offset" label. A menu appearsover the sonar screen that says "Enter Keel Offset 0.0" as shown below.
r The 2-9500 lets you measure the water depth from the surface to the bottom with the Positive Keel Offset feature. It works by adding the depth of the transducer to the bottom depth. In other words, if the actual bottom depth from the surface is ten feet, but the transducer's face is twofeet beneaththe surface, then the2-9500thinksthe bottom is only eight feet deep. Using Positive Keel Offset, two feet can be added to this, making the Z-9500display the true bottom depth of ten feet.
ASE Correction Loran signals are affected by the terraintheytravel over. Plains, lakes, mountains, and cities affect the signal and they each affect it in different ways. This effect is called the additional secondaryphase factor, or ASF. It's usually factored in when a loran chart is made. However, ASF's vary fromplace to place, so there can bedifferencesbetween the chadand the real world. There can also be a difference in your actual position and the one displayed by the bran, due to ASF.
fl- DIGITAL SONAR FREQUENCY SELECT The Z-9500's digital has the capability of using the 192 kHz or 50 kHz frequency. Please note that the frequcency used by the digitalcan be differentthan that used by the chart. Changing thedigital's frequency doesn't affect the chart's frequencyat all. When the unit is turned on forthefirst time or preset, the192 kHzfrequencyis usedforthe digital. The 50 kHz frequency'sbiggest advantage is irs superior depth penetration.
LORAN ALARMS The Z-9500 has two loran alarms. One is an arrival alarm that sounds when you come within a preset distanceto a waypoint. The other is a C.D.l. alarm that sounds when you move off course more than the alarm's set point. SiFT AUTOJ 50kHz Digital 50KHZ Sonar 12 24 ARRIVAL ALARM The arrival alarm sounds a tone whenyour position is withinthe alarm's radius of a waypoint.

HOW LORAN-C WORKS The Loran system consistsof three to six transmitterstations. These are called a "chain." The letter "M" designates the masterstation inside the chain. The other stations in the chain are the secondaries. Their names are V, W, X, Y, and Z, althoughnot all chains havefive secondary stations. The secondarytransmitters are synchronized with the master which transmits at precise time intervals. This time interval is called the Group Repetition Interval (GRI). Each chain has a different GRI.
Saving Present Positionas a Waypoint (Save As #) To save your present position using this feature, first press the Waypoint Save key. The menu shown below appears. Now press the key adjacent to the"SAVEAS #" label. The Z-9500stores your present position under the waypoint number shown on the label. The waypoint number increments each time you save a waypoint, so you don't have to keep track of the waypoint numbers. Once you've stored the waypoint,theZ-9500 returns to theloran display.

You don't haveto know which stationsare bestor the CR1 to usethe initial position only startup. However, when the Z-9500 is in the automatic mode, it can change stations at any time if it decidesone or more stationsare better to use than others. This can result in small position inaccuracies. For example, suppose you use the bran one day and save a waypoint.
