SECTION 3INSTALLATIONThis section provides practical guidelines to assist in the planning and installation of the RADAR 1500 MK2.3.1 UNPACKING AND INSPECTIONUse care when unpacking the RADAR 1500 MK2 from the shipping carton toprevent damage to the contents.

It is also good practice to save the carton andthe interior packing material until the radar has been satisfactorily installed.The original packing material should be used in the unlikely event that it isnecessary to return the unit for service. 3.3 MOUNTING THE DISPLAY UNITWhen planning the installation for your display unit, the following conditionsshould be considered to ensure dependable and trouble-free operation.1) The mounting location should be accessible enough to allow easy operationof all the front panel controls.2) There should be adequate ventilation.3) There should be sufficient space behind the display unit to allow for cableconnections to its rear.4) The display unit should be located near a DC power source.

When the display unit is mounted overhead, remove the mounting plate, whichis secured by four screws and rotate it through 180 degrees for re-assembly onthe other side of the unit.4 SCREWSBRACKETDISPLAY UNITMOUNTINGPLATEBRACKETThe display unit is separated fromthe bracket in the shipping carton.Install the display unit by slidingit onto the bracket until it is fullyseated.To remove the unit simply depress the latch on the rear of thedisplay unit and lift. 3-3 DISPLAY MOUNTING DIMENSIONSFIG. 3.4 MOUNTING THE SCANNER UNITCAUTIONThe scanner unit requires a minimum mounting surface thickness of 3 mm (0.12 inches).

If the thickness of the mounting baseis less than this, additional flat washers are required. If the thickness is more than 15 mm (0.6 inches), longer hexhead bolts arerequired.Selecting an adequate location for the scanner unit requires careful consideration.

Usually, the mounting surface for thescanner unit should be parallel withthe ship’s waterline. Some vessels,however, may adopt a higher bowangle at some cruising speeds. Thissubstantially alters and raises theradar’s radiation plane. In this casenearby target detection might bepoor.

It may be helpful to lower theradar beam towards the FORWARDparallel by shimming the radar pedestal in order to tilt the beam angleslightly downward with respect tothe waterline. 3-6 ASSEMBLING PROCEDURE FOR CABLE14INSTALLATIONbSHIELD COVERaCABLEaREDOMETURN THE RADIATORTHIS DIRECTION.bcGASKET BGASKET AdcedeGASKET BGASKET ADON'T PILE GROOVES. 3.6 ELECTRICAL CONNECTION3.6.1 DC POWER CABLEThe RADAR 1500 MK2 will work with any electrical supply within the 10.2to 16 V range, since it contains a power regulator circuit.

SART operates in the 9 GHz frequency band.

When it receives aradar signal (interrogating radio wave) of 9 GHz transmitted by a rescue ship oraircraft radar, SART transmits a series of respouse signals to the searchers toindicate the distress position. SECTION 5MAINTENANCEThe purpose of this section is to provide instructions for the service technician.The RADAR 1500 MK2 is designed to provide long periods of trouble freeoperation. However, environmental and other factors may require this equipment to be periodically serviced.WARNINGThis radar equipment contains high voltage. Adjustments require specialized service procedures and tools only available toqualified service technicians. (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.

T o avoid electrical shock, never touch the inside of the scanner when it is connected to an electrical supply. Always keep the protective cove r on the scanner when it is connected to an electrical supply. High internal voltages can cause serious per- sonal injury. The equipment should be routinely serviced, only by JRC authorised personnel. A void passing close to the scanner when the radar is in use.

The scanner unit rotates quickly and can cause personal injury. Both this and the enclosed radome should be installed at a high place, such as a cabin roof, or a specially constructed arch, or radar mast. If the radiating units cannot be installed above all possible, standing head height, they should be guarded by a strong, protectiv e, enclosing frame.

Prolonged, close range exposure to radar signals is not recommended. Before approaching close to the scanner, or dismounting it, ensure that the STBY/OFF and the X-MIT/OFF keys on the display unit have both been turned off. The cable connector P1 at the rear of the display unit should be disconnected before removing the scanner unit from its installed position. Never sit on the scanner, nor otherwise subject them to weight.

They are not intended to bear loads and ignoring this advice could cause damage to important internal components. You will only get optimum performance from your RADAR 1000 MK.
