Resumen del manual
3. Press v or ^ to select the clarity level, then press EXIT|EXIT|EXIT. Surface clutter In the illustration on the left, Surface Clarity is turned off. The view on the right shows Surface Clarity set on high. Zoom & Zoom Bar "Zooming in" is a common, fast and easy method to enlarge small detail like fish signals and bottom structure. This unit lets you zoom in quickly and easily by pressing the ZIN key. 83 Pressing ZIN once doubles the size (2X) of all echoes on the screen. Pressing it again quadruples the size of the echoes (4X). The zoom bar on the far right side of the screen shows which echoes will be displayed on the screen when the ZIN key is pressed. For example, pressing the ZIN key once will enable a 2X zoom that will show all echoes between the top and bottom of the 2X-zoom bar. Pressing the key again will give a 4X zoom and only the echoes between the top and bottom of the 4X bar will show on the screen. Press the Zoom Out key, ZOUT, to return the display to the normal mode. Sonar page zoomed 2X (left). The same view zoomed 4X (right). Zoom Pan Your unit has the handy ability to quickly zoom in on any portion of the water column with just the touch of an arrow key. The Zoom Pan feature lets you rapidly move the display up and down the zoomed area, allowing you to focus on areas of interest in the water column below you. To use Zoom Pan, switch to a Manual Depth Range setting (see page 61) and turn on 2X or 4X Zoom. Then press ^ or v to pan up and down the water column. 84 Section 5: Sonar Troubleshooting If your unit is not working, or if you need technical help, please use the following troubleshooting section before contacting the factory customer service department. It may save you the trouble of returning your unit for repair. For contact information, refer to the last page, just inside the back cover of this manual. Unit won't turn on: 1. Check the power cable's connection at the unit. Also check the wiring. 2. Make certain the power cable is wired properly. The red wire connects to the positive battery terminal, black to negative or ground. 3. Check the fuse. 4. Measure the battery voltage at the unit's power connector. It should be at least 11 volts. If it isn't, the wiring to the unit is defective, the battery terminals or wiring on the terminals are corroded, or the battery needs charging. Unit operates only in demo mode: The transducer or antenna module have not yet been connected or have been disconnected. To leave demo mode, make sure that either the transducer or the antenna is securely connected before turning the unit on. Unit freezes, locks up, or operates erratically: 1. Electrical noise from the boat's motor, trolling motor, or an accessory may be interfering with the sonar unit. Rerouting the power and transducer cables away from other electrical wiring on the boat may help. Route the sonar unit's power cable directly to the battery instead of through a fuse block or ignition switch. 2. Inspect the transducer cable for breaks, cuts, or pinched wires. 3. Check both the transducer and power connectors. Make certain both are securely plugged in to the unit. Weak bottom echo, digital readings erratic, or no fish signals: 1. Make certain the transducer is pointing straight down. Clean the face of the transducer. Oil, dirt and fuel can cause a film to form on the transducer, reducing its effectiveness. If the transducer is mounted inside the hull, be sure it is shooting through only one layer of fiberglass and that it is securely bonded to the hull. Do NOT use RTV silicone rubber adhesive or Marine-Tex. epoxy. 2. Electrical noise from the boat's motor can interfere with the sonar. This causes the sonar to automatically increase its Discrimination or 85 noise rejection feature. This can cause the unit to eliminate weaker signals such as fish or even structure from the display. 3. The water may be deeper than the sonar's ability to find the bottom. If the sonar can't find the bottom signal while it's in the automatic mode, the digital sonar display will flash continuously. It may change the range to limits far greater than the water you are in. If this happens, place the unit in the manual mode, then change the range to a realistic one, (for example, 0-100 feet) and increase the sensitivity. As you move into shallower water, a bottom signal should appear. 4. Check the battery voltage. If the voltage drops, the unit's transmitter power also drops, reducing its ability to find the bottom or targets. Bottom echo disappears at high speeds or erratic digital reading or weak bottom echo while boat is moving 1. The transducer may be in turbulent water. It must be mounted in a smooth flow of water in order for the sonar to work at all boat speeds. Air bubbles in the water disrupt the sonar signals, interfering with its ability to find the bottom or other targets. The technical term for this is cavitation. 2. Electrical noise from the boat's motor can interfere with the sonar. This causes the s...
