    Should you experience a problem with your Color Twinscope, first refer to the Troubleshooting section (Page 38) of this manual. Most common problems and their solutions are described here.

  • Page 5: Principle Of Operation

    Principle of Operation The Color Twinscope Forward Scanning Sonar uses a proprietary and patented phased array acoustic technology first developed for marine use by Interphase Technologies. Known as “phased array ultrasound technology”, its capabilities have been proven in the military and medical industries for many years.

    Blac Installation Display Unit The compact size of the Color Twinscope 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 Color Twinscope 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 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 11: Transducer Installation

    Transducer Installation The Color Twinscope comes standard with either a single or twin thru-hull or with two transom mount forward scanning transducers. The Color Twinscope uses two phased arrays. In the single thru-hull model both arrays are enclosed in a single transducer.

    After mounting the transducer and actually using the Color Twinscope on the water, you may need to readjust the transducer’s mounting for optimum performance. Thru-Hull Transducer Installation The thru-hull transducer is the recommended choice for larger boats with in-board engines.
  • Page 16 Because the Color Twinscope 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 17 After cutting the fairing block, trial fit the block to the hull. It is very important that the flat top surface of the transducer be parallel to the water. Because of the skill required, we suggest that your professional boatyard provide the fairing block.

    SET-UP Menu, please refer to the SET-UP section on page 20-21. DEMO Your Color Twinscope 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.

    MAX G 100 FT MORE The Color Twinscope 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 21 In addition, severe surface clutter can cause the alarms to sound. To minimize these types of problems, the Color Twinscope includes an STC Adjustment. STC stands for Surface Time Constant and you can use it to force the Color Twinscope to ignore surface clutter.

    Once adjusted, the Color Twinscope’s memory will retain the setting. Demo If the DEMO softkey is pressed the Color Twinscope will go into a demonstration mode where simulated data is sent K = +03.1 Ft L = +10 to the display.

  • Page 29: Video Input

    See diagram at bottom of previous page. Video Inputs The Color Twinscope 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 Color Twinscope’s display.

  • Page 30: Interpreting The 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 Color Twinscope 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.

As the Color Twinscope sends off its acoustic beam in a specific direction, it assumes that any return echoes are within the main beam. However, if the sidelobe energy (which is not within the main beam) strikes a large object (i.e.

  • Page 38: Maintenance

    Maintenance Below are some helpful tips for keeping your Color Twinscope in top condition: 1) Keep your display clean and dry. Occasionally wipe unit off with a damp cloth, but be careful not to scratch the lens covering the LCD screen. For stubborn dirt, use a mild soap and a damp cloth. NEVER USE SOLVENTS SUCH AS PAINT THINNER, ACETONE, OR GASOLINE TO CLEAN YOUR UNIT.

  • Page 39: Interference Problems

    (i.e.; bilge pumps, motors, refrigeration systems, autopilots, etc.) Interference caused by nearby depth sounders operating on or near the same frequency as the Color Twinscope will typically appear as “rabbit tracks” that march up and down the screen. Reducing the gain will help minimize this problem.
