  • Page 14: Installation

    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.

  • Page 16: Mounting The Display Unit

    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.
  • Page 17 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.

  • Page 19: Mounting The Scanner Unit

    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.

  • Page 22: Electrical Connection

    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.

    3.7 INITIAL OPERATION AND SET UP 3.7.1 INSPECTION AFTER INSTALLATION After completing the installation and prior to energizing the equipment, it is necessary to ensure that all steps of the installation were accomplished in ac- cordance with the instructions. Make sure that: (1) The cables are not pinched or damaged.

  • Page 27 3.7.5 RELATIVE BEARING ALIGNMENT This step must be performed. Failure to do so may result in incorrect bearing readings. ① Set the range to 1.5 NM. ② Identify a suitable target such as a buoy and position the boat between 0.5 NM and 1 NM.
  • Page 28 3.7.7 Buzzer ON or OFF ① In the INITIAL SET UP MENU select BUZZER. ② Select ON or OFF. ③ Press JOYSTICK when done. 3.7.8 OPERATOR PROMPTS Operation prompts can be helpful to new users operating the radar. The default setting is ON.
  • Page 29: Operation

    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.
  • Page 30: Turning The Radar On And Off

    4.2 TURNING THE RADAR ON AND OFF TO TURN ON Press the STBY/OFF key. TO TRANSMIT Press the X-MIT key. TO STAND-BY Press the STBY/OFF key. TO TURN OFF Press the STBY/OFF key and the X-MIT/OFF key si- multaneously. When you Press the STBY/OFF key, a 90 second warm-up count down timer is activated and displayed together with the total (display unit) usage to date.

    4.3 SELECTING A RANGE Press the J-DIAL until RANGE is highlighted in the upper right corner of the display. The range scale and range rings setting in use is shown in the upper left corner. Rotate the J-DIAL clockwise to increase the range and anti-clockwise to decrease it.
  • Page 33: Reducing Sea Clutter

    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.

    4.10 SETTING 1/4 OFFSET By pressing the OFFSET key, the display is offset downwards by 1/4 radius, expanding the display area in front of the vessel. Press the key a second time to return the display to normal.

  • Page 37: Setting Guard

    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.
  • Page 38: Rings

    4.15 RINGS The range rings can be turned to on or off via this menu. 4.16 POSITION Select this option to display the ship’s position (derived from a navaid input). This function allows selection of ship’s position in latitude/longitude (LL), time difference (TD) position, you may also display waypoint (WPT) as a LL posi- tion in place of your own position data.
  • Page 39: Target Expansion

    4.20 TARGET EXPANSION Target expand mode can be set to “on” or “off”. When “on”, this function in- creases the size of the displayed images to make small targets appear larger and easier to view on screen. When active,“EXP” is highlighted in the upper left area of the screen.

    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.
  • Page 42: Maintenance

    SECTION 5 MAINTENANCE The purpose of this section is to provide instructions for the service technician. The RADAR 1500 MK2 is designed to provide long periods of trouble free operation. However, environmental and other factors may require this equip- ment to be periodically serviced. This radar equipment contains high voltage.
  • Page 43: Cleaning (Monthly Intervals)

    (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.
  • Page 44: After-Sales Service

    SECTION 6 AFTER-SALES SERVICE To verify ownership and warranty registration, you should take a few minutes to fill out your warranty registration card in the front of the manual. It is very important that you take time to fill out this card.
