    SECTION 3 INSTALLATION This section provides practical guidelines to assist in the planning and installa- tion of the RADAR 1500 MK2. 3.1 UNPACKING AND INSPECTION Use care when unpacking the RADAR 1500 MK2 from the shipping carton to prevent damage to the contents. It is also good practice to save the carton and the interior packing material until the radar has been satisfactorily installed.

    3.3 MOUNTING THE DISPLAY UNIT When planning the installation for your display unit, the following conditions should be considered to ensure dependable and trouble-free operation. 1) The mounting location should be accessible enough to allow easy operation of all the front panel controls. 2) There should be adequate ventilation.

    When the display unit is mounted overhead, remove the mounting plate, which is secured by four screws and rotate it through 180 degrees for re-assembly on the other side of the unit. DISPLAY UNIT BRACKET The display unit is separated from the bracket in the shipping carton.

    3.4 MOUNTING THE SCANNER UNIT The scanner unit requires a minimum mounting surface thick- ness of 3 mm (0.12 inches). If the thickness of the mounting base is less than this, additional flat washers are required. If the thick- ness is more than 15 mm (0.6 inches), longer hexhead bolts are required.

  • Page 20: Connecting The Scanner Unit Cable

    Usually, the mounting surface for the scanner unit should be parallel with the ship’s waterline. Some vessels, however, may adopt a higher bow angle at some cruising speeds. This substantially alters and raises the radar’s radiation plane. In this case nearby target detection might be poor.

    3.6 ELECTRICAL CONNECTION 3.6.1 DC POWER CABLE The RADAR 1500 MK2 will work with any electrical supply within the 10.2 to 16 V range, since it contains a power regulator circuit. Connect the power cable to a DC source capable of supplying at least 3.5 A. The power cable should normally be wired through a circuit breaker.

  • Page 29: Section 4 Operation, Layout Of Controls

    In normal operation the RADAR 1500 MK2 is very easy to use and several of its functions are totally automatic. However, the prudent navigator spends time in good visibility to learn the layout of the controls and to become proficient in their use, so that he/she will obtain the best performance from the equipment when the visibility is poor, or the sea area is crowded.

    4.6 REDUCING SEA CLUTTER Increasing the SEA CLUTTER control effectively diminishes the radar’s sensitivity. SEA CLUTTER should never be advanced to the point where it obliterates all returns from waves, since this setting could prevent the detection of nearby targets, especially small wood/grp boats and yachts approaching head-on.

    4.14 SETTING GUARD The guard zone alarm is effective for alerting the operator to targets approach- ing his own ship. An alarm is sounded when any (apparent) target returning an echo above the noise threshold is detected. If sea clutter, or other incidental echoes trip the alarm, adjust the gain control and/or the sea clutter to avoid this false alarming.

    4.26 DISPLAY OF RADAR TRANSPONDER SART (Search and Rescur Radar Transponder) is life preserving device ap- proved by GMDSS which is used for locating survivors in the event of a disas- ter or distress. SART operates in the 9 GHz frequency band. When it receives a radar signal (interrogating radio wave) of 9 GHz transmitted by a rescue ship or aircraft radar, SART transmits a series of respouse signals to the searchers to indicate the distress position.

    (2) Check for any evidence of corrosion in the scanner unit and display unit, or their cables and connecotrs. Clean as reuired. (3) Check that the cable connector is secure. 5.2 CLEANING (MONTHLY INTERVALS) Wash the exterior of the scanner with fresh water, but do not immerse the unit. A heavy deposit of dirt, or caked salt on the surface of the scanner may cause a considerable drop in the radar performance.
