Ct HER pe Depth Range Lower Zoom Limit USING THE 350TX MENU FUNCTIONS which the Zoom range is constantly adjusted to show the bottom or manually in which the user controls the location of the Zoom range Automatic Zoom is especially helpful when looking for structure or bottom detail The Automatic Zoom keeps the bottom in view even in quickly changing terrain but is most useful in flatter areas without considerable depth variation Manual Zoom provides detailed information of any area from the surface to the bottom In manual Zoom the Zoom range does not move as the terrain changes When the range is shown in the menu the upper number represents the top of the current Zoom range The lower number represents the bottom of the Zoom range Use the UP and DOWN ARROW buttons to move this range The upper number can never be less than O the surface of the water and the lower number can never be greater than the active depth range The difference between the two numbers the Zoom range is preset and determined by the active depth range Once manual Zoom is selected the display appears the same as in Auto Zoom but the zoom range does not change automatically To disable Zoom press the MENU button until the Zoom menu is on screen Use the UP ARROW to highlight Off and let the menu time out When the unit is powered off the Zoom menu returns to Zoom Off Depth2. INSTALLATION PREPARATION INSTALLATION OVERVIEW display on the control head It should be installed in contact with the surface of the water in an area that has smooth water flow usually on the transom of the boat There are several mounting options for the transducer Review the following section to determine the method that works for you and your boat Determining How to Mount the Transducer The 350TX includes a model XT 6 TB 90 transducer This transducer can be mounted on the transom of the boat or bonded to the inside of a fiberglass hull boat The transom installation which is the most widely used places the transducer on the outside of the boat hull This technique produces the least signal loss and provides a way to adjust the transducer after installation The mounting hardware included is designed to protect both the boat and the transducer should the boat strike debris in the water or when trailering Transom Mounted Transducer As an alternative to transom mounting it is possible on many fiberglass hulled boats to glue the transducer on the inside of the boat hull Since fiberglass has similar sonar character istics as water the sonar signal can pass through the boat hull with minimal loss The hull of the boat must be single layer construction double hulled Also any air trapped in the lamination of the fiberglass would prevent the sonar signal from passing through Inside the Hull Mounte

15. trouble free operation with virtually no maintenance Follow these simple procedures to ensure your 350TX continues to deliver top performance e If the unit comes into contact with salt spray simply wipe the affected surfaces with a cloth dampened in fresh water Do not use a chemical glass cleaner on the lens Chemicals in the solution may cause cracking in the lens of the unit When cleaning the LCD protective lens use a chamois and non abrasive mild cleaner Do not wipe while dirt or grease is on the lens Be careful to avoid scratching the lens e If your boat remains in the water for long periods of time algae and other marine growth can reduce the effectiveness of the transducer Periodically clean the face of the transducer with liquid detergent Pivoting the transducer up in the bracket may allow better access for inspection or cleaning If your boat remains out of the water for a long period of time it may take some time to wet the transducer when returned to the water Small air bubbles can cling to the surface of the transducer and interfere with proper operation These bubbles dissipate with time or you can wipe the face of the transducer with your fingers after the transducer is in the water e Never leave the 350TX in a closed car or trunk the extremely high temperatures generated in hot weather can damage the electronics TROUBLESHOOTING Do not attempt to repair the 350TX yourself There are no user serviceab
