  • Page 4: Important Notice

    General Information hank you for your selection of the Interphase iScan V90 Forward Scanning Sonar. The iScan V90’s ruggedly built, compact design makes it ideal for installation on nearly any boat.

  • Page 5: Principle Of Operation

    For example, using an 8 element phased array transducer, the iScan V90 is capable of steering the acoustic beam in any of 60 different directions. Since the acoustic beam in the phased array is steered electronically, requiring no moving parts, it can be quickly and reliably scanned and re-scanned over a large area.

  • Page 6: Display Unit Installation

    Display Installation Display Unit The compact size of the iScan V90 display unit allows for easy installation in almost any vessel. To get maximum performance and life from your unit, the following guidelines should be considered when selecting a mounting location: 1) Select a location where the unit is protected from excessive temperatures.
  • Page 7 In - Dash Mounting The iScan V90 comes with mounting hardware to mount the display in-dash. Four mounting screws and a cutout diagram are included. For in-dash mounting, the mounting base portion of the Quick Disconnect Mount is removed. To remove the mounting base loosen the thumb screw until it seperates from the upper portion of the Quick Disconnect Mount.

  • Page 9: Selecting The Transducer Configuration For Your Boat

    Selecting the Transducer Configuration for your Boat Keep in mind the primary rule for transducer operation. This is: the transducer can function as long as it has an unobstructed forward view and has smooth flowing non-aerated water surrounding it. The first line of inquiry should be about the boat. Transom mounted transducers are intended for low speed boats with external props.

  • Page 10: Transducer Installation

    Prior to installing the transducer review the Selecting the Transducer Configuration guidelines on Page 9. The iScan V90 comes standard with either a thru-hull or transom mounted forward scanning transducer. It is important to position the transducer so that it has as clear a view as possible of the water directly below and ahead of your boat, as indicated at left.

  • Page 12 Kick-up Bracket Replacement Parts If during installation parts are somehow lost are damaged, they can be replaced as follows: Part# 17-0088-008 - Spray Shield Kit - Includes: Spray Shield, four Mounting Bolts and Nuts, Rubber Grommet and four Large Mounting Screws. Part# 17-0089-008 - Transom Transducer Hardware Kit - Includes: Complete Bracket Axle Assembly and four Large Mounting Screws.
  • Page 13 After mounting the transducer and actually using the iScan V90 on the water, you may need to readjust the transducer’s mounting for optimum performance.

  • Page 14: Selecting The Best Location

    The iScan V90 must have a clear view of the water ahead as it can not magically see through obstructions such as the vessel’s hull.
  • Page 15 Forward require tightening from inside the hull. Because the iScan V90 scans a 12 degree beam from the surface ahead to directly below the boat, it is important to make sure that the transducer is installed so that it will scan in a vertical direction and not off to either side.
  • Page 16 2) Use a 1-1/16” hole saw and drill the hole from the outside of the hull. Sand or clean the area around the hole, inside and outside to insure that the sealing compound will adhere properly to the hull. Select a marine grade adhesive sealant, such as 3M 5200, and use according to the instructions.

    SET-UP Menu, please refer to the SET-UP section on pages 19-20. DEMO Your iScan V90 includes a built-in DEMO simulator program which makes it easy to practice with the unit and to get a feeling for its many features before actually using it in real situations on the water.

  • Page 19: Set-Up

    MAX G 100 FT MORE The iScan V90 allows you to customize the maximum possible gain for each range. The table below shows a suggested range of Max Gain settings that you can set. Too much gain on the shallow ranges will cause excess noise and false forward targets.
  • Page 20 To minimize these types of problems, the iScan V90 includes an STC Adjustment. STC stands for Surface Time Constant and you can use it to force the iScan V90 to ignore surface clutter. By default, the STC is set to 5 feet - meaning that the digital depth and alarms will ignore anything closer than 5’...

    ALARM SET-UP Down Display (Conventional down looking) By pressing the DOWN button - once, the iScan V90’s display will split and a conventional downlooking display will appear at the left side of the screen as shown on the right. The downlooking split screen mode will work in either the vertical or horizontal display modes.

    Gain Adjustment (Sentivity) Press the button labeled GAIN to bring up the choices available for adjusting the iScan V90 s receiver GAIN. Press the button below AUTO so that the word AUTO is shown with a red border if you would like the Color Twinscope to automatically adjust its receiver gain for changing conditions.

  • Page 26: Screen Cursor

    (On forward ranges below 200 feet, it’s recommended to keep the gain below the number 10.) Screen Cursor The iScan V90 has a useful screen cursor feature that can show the approximate depth and range from the vessel to any target on a forward scanning display.

    See diagram at bottom of previous page. Video Inputs The iScan V90 has a 3-pin video input connector on the rear panel. You can connect video cameras, VCR, DVD and other sources of NTSC OR PAL signals to this connector and view them in a full-screen format on the iScan V90’s...

  • Page 29: Interpreting The Forward Vertical Display

    The Phased Array Transducer steers an acoustic beam over an arc which can be adjusted from approximately 12 to 90 degrees. As the iScan V90 steers the beam to different positions, it transmits a pulse of energy and then waits a defined period of time (depending on the range selected) and listens for any return echoes.
