LTD260.qxd 12/15/98 8:24 AM Page 2 Digital Depth Sounder LTD 260 TO OUR CUSTOMER: We would like to extend our thanks to you for purchasing the LTD 260. This product is a highly sophisticated instrument which is designed using the criteria “simplicity of operation”. It is very important that you review this manual carefully and thoroughly prior to using your President instrument.
LTD260.qxd 12/15/98 8:24 AM Page 3 GENERAL OVERVIEW: This manual has been arranged in the sequence outlined below. This overview below will provide you with a correct sequence of events required to successfully install and operate your instrument.

LTD260.qxd 12/15/98 8:24 AM Page 4 INSTALLATION: LTD 260 First, find a location on your dash panel which will give clear viewing and access to the LCD window. After finding the right location for the indicator unit, mark a 2 in. hole to be cut out. Check behind the panel for any cables or wiring which could be damaged and then cut out the 2 in. hole. Test fit the unit in the hole and make any adjustments with our saw or drill. Extending out of the back of the instrument, you will notice a brass shaft.
LTD260.qxd 12/15/98 8:24 AM Page 5 INSTALLATION: POWER SOURCE BATTERY CONNECTION/POWER REQUIREMENT Because the LTD 260 has no ON/OFF switch, you will need to wire it directly to a power source which will turn the unit on as power is applied. It may be a power source which will turn the unit on as power is applied. It may be convenient to wire the power cable directly to the Ignition Switch so that when you turn the boat on, the depth sounder immediately starts working.
LTD260.qxd 12/15/98 8:24 AM Page 6 AIR ECHOES: Air echoes can be caused by too much turbulence under the face of the transducer. It is important to know that ultra sonic signals from a transducer will not penetrate air. They react to air in the same manner as they react to a hard bottom described above.
LTD260.qxd 12/15/98 8:24 AM Page 7 INSTALLATION: DEPTH TRANSDUCERS TRANSDUCER WETTING Immediately before your vessel, thoroughly wipe the face of the transducer with a detergent type liquid soap. This reduces the amount of time required for the transducer to establish good contact with the water. If this procedure is not followed it may take several days for the complete “wetting” to occur, resulting in reduced performance of the instrument.
LTD260.qxd 12/15/98 8:24 AM Page 8 INSTALLATION: TRANSOM MOUNT TRANSDUCERS WARNING: DO NOT INSTALL UNDERNEATH A GASOLINE OVERFLOW AS THIS WILL DESTROY THE PLASTIC MATERIAL OF THE TRANSDUCER AND THE BRACKET AND IS NOT COVERED UNDER WARRANTY. Also, do not use LOCKTITE or any similar adhesives on the mounting hardware as these materials also destroy the transducer. 1. 2. 3. 4. 5. 6. Attach the transducer to the bracket as shown.
LTD260.qxd 12/15/98 8:24 AM Page 9 INSTALLATION: THROUGH-THE-HULL TRANSDUCERS In mounting a transducer through the hull (through-hull), it is important that it is done correctly because the location of the transducer on the hull will determine how well the entire unit will perform. There are several factors involved in choosing a good location for a through hull transducer.
LTD260.qxd 12/15/98 8:24 AM Page 10 INSTALLATION: POWERBOAT BRONZE TRANSDUCERS This style of transducer is popular as a replacement transducer since it was the primary style used on older boats and the stern will fir the same size hole as the previous defective or obsolete transducer. In order to provide good, steady readings, it requires the use of a fairing block. Without a fairing block, the large portion of the transducer is unprotected and runs the risk of being hit off by objects in the water.
LTD260.qxd 12/15/98 8:24 AM Page 11 INSTALLATION: INSIDE THE HULL TRANSDUCERS This type of transducer is very popular since it does not require the drilling of a hole such as the through-the-hull transducer. However, you should consider the disadvantage due to the possible loss of sensitivity which could cause a measurable depth loss in terms of maximum depth capability.
LTD260.qxd 12/15/98 8:24 AM Page 12 7. Apply the mixture to the clean location on the hull and to the face of the transducer in a small amount. 8. Press the face of the transducer into the spot of epoxy and slowly rotate it ¼ turn to remove any air bubbles and until the transducer is physically against the hull or with ¼” of the hull. When the epoxy has cured, it should be permanently bonded to the hull and hard to the touch.
LTD260.qxd 12/15/98 8:24 AM Page 13 GLOSSARY A partial list of terms used is presented herein. BEAM ANGLE: A transducer beam angle is shaped in an inverted cone (narrow at the top and larger at the bottom). Most of the energy from the instrument is reflected back to the transducer when it hits bottom. There are different beam angles for different purposes.
LTD260.qxd 12/15/98 8:24 AM Page 14 TROUBLESHOOTING: SYMPTOM: CHECK: GENERAL OPERATION Unit does not turn on at all. No beep, no display. Make sure the unit is actually receiving power. Check the inline fuse, and the circuit breaker panel on the boat. Make certain the unit is receiving 11 to 16 colts of CLEAN DC. Make sure the DC polarity has not been reversed. Check for corrosion on the power connector, and clean if necessary. SYMPTOM: “0.0” FLASHING in display window.
LTD260.qxd 12/15/98 8:24 AM Page 15 SYMPTOM: Unit smoked. REASON: A wire from he transducer was accidentally plugged into the Remote Alarm terminal located next to the power + or - terminals. HOW TO SOLVE: Return the unit to the factory for repair. SYMPTOM: Transom mount transducer breaking where the mounting bracket attaches to the transducer.
LTD260.qxd 12/15/98 8:24 AM Page 16 Each depth gauge is tested at the factory with a transducer located in a water tank and the Shallow Water Sensitivity is factory pre-set. However, during shipment, after installation or in your local waterways, it may require that you perform this minor adjustment so that it performs to its maximum potential on your boat.
LTD260.qxd 12/15/98 8:24 AM Page 17 CARE AND MAINTENANCE: ● ● ● Never spray directly with a hose or otherwise submerge your unit. Never use harsh cleaners or solvents (gasoline, window cleaner etc.) to clean your instrument or the transducer or paddle wheel. Do not use Locktite® on any plastic parts like the transducer since it will disintegrate the material and destroy the plastic. This kind of damage is not covered under warranty.
