[. . . ] The word !"" will be displayed but the alarm depth will be retained for future use. Surface Offset (Depth below the surface) 3. After 5 seconds the display will indicate the current offset. Note: A negative offset is used to display depth below the keel and a positive offset is used to display depth below the surface. 4 DS45 Owner's Manual 4. If either key is held depressed for more than one second the reading will increase or decrease rapidly. The offset can be programmed in 0. 1 unit steps from -9. 9!9. 9 feet (or equivalent). When programmed for a negative offset, `-' will be indicated on the left hand side of the display. To display depth below the keel enter the vertical distance between the bottom of the keel and the depth trasnducer as a negative value. To display depth below surface enter the vertical distance from the waterline to the depth transducer as a positive number (no negative sign). To exit this mode, press and hold both the " and # keys simultaneously. Alternatively, if no keys are pressed for a period of 5 seconds normal depth display will resume. ON 2. After 2 seconds the display will show the Transducer Setting value eg 0. 0 5. To exit this mode, press and hold both the " and # keys simultaneously. tdr Units of Measure To select the displayed unit 1. Part Number 580010123A 8 DS45 Owner's Manual Installation Face Plate Installation 1. To install a face plate: a) Attach the face plate to the front panel of the instrument. · · · Location should provide as much protection from the elements as possible. The panel for mounting the instrument should be 1/8 to 3/4 inch thick. The space behind the instrument panel must have a depth of at least 3. 75 inches. See Figure 1 for dimensions of the instrument. Instrument Installation The instrument can be easily installed in different types of instrument panels. Select a location for the transducer using the following guidelines: · Non-aerated water (bubble-free) water must flow across the face of the transducer at all speeds if good depth performance is to be achieved. Never position the transducer directly behind shafts, struts, fittings and paddlewheel speed transducers because water turbulence underneath the transducer face can adversely affect depth performance. Keep the transducer cable away from the engine to reduce electrical interference. If the boat has bottom paint applied and has been used, inspect for areas where paint erosion has taken place. Erosion is caused by turbulent water and these areas are unsuitable transducer mounting locations. [. . . ] In-Hull Installation DS45 Owner's Manual 13 Appendix A ­ Dual Station Operation Multiple DS45 instruments can be installed on a single vessel. These instruments can be connected together and configured to operate in a dual station configuration. One instrument is designated as a master and all other instruments, connected to it, are configured as slaves. The master device is connected to the depth transducer and determines the water depth.
