11. MOUNTING1.1 Mounting Considerations• The radar sensor is generally installed either on top of the wheelhouse or on the radar mast on a suitable platform. Locate the radar sensor where there is a good all-round view. Any obstruc-tion will cause shadow and blind sectors. A mast for instance, with a diameter considerably less than the horizontal beamwidth of the radiator, will cause only a small blind sector, but a horizon-tal spreader or crosstrees in the same horizontal plane as the radar sensor would be a much more serious obstruction; you would need to place the radar sensor well above or below it.• It is rarely possible to place the radar sensor where a completely clear view in all directions is available. Thus, you should determine the angular width and relative bearing of any shadow sectors for their influence on the radar at the first opportunity after fitting.• A magnetic compass will be affected if the radar sensor is placed too close to it. Observe the compass safe distances mentioned in the SAFETY INSTRUCTIONS to prevent interference to a magnetic compass.• Do not paint the radiator aperture, to ensure proper emision of the radar waves.• When this radar sensor is to be installed on large vessels, consider the following points:• The signal cable run between the radar sensor and MFDBB, MFD8 or MFD12 comes in lengths of 10 m, 15 m, 20 m and 30 m.• Deposits and fumes from a funnel or other exhaust vent can adversely affect the aerial per-formance and hot gases may distort the radiator portion. The radar sensor must not be mounted where the temperature is more than 70°C.As shown in the figure below, the radar sensor may be installed on the bridge, on a common mast or on the radar mast.For DRS4A/6A(a) On bridge (b) Common mast (c) Radar mast

71.3 Mounting Procedure for DRS2D4D1. Remove mounting hardware at the bottom of the radar sensor, four each of hex bolts (M10x20), spring washers and flat washers. Save the spring washers and flat washers to use them to fix the radome base to the platform, at step 3. If the thickness of the mounting platform is 5 mm or less also save the bolts.2. Construct a platform (wood, steel or aluminum) 6-10 mm in thickness referring to the outline drawing at the back of this manual. (A mounting bracket for mounting the radar sensor on a sailboat mast is optionally available.) Fasten the platform to the mounting location. Next, posi-tion the base so the cable entrance faces the stern direction.Note: When drilling holes in the platform, be sure they are parallel with the fore and aft line.3. Using the hex bolts*, flat washers and spring washers removed at step 1, fastgen the radome base to the platform. The torque should be between 19.6-24.5Nm.*If the thickness of the platfoirm is 6-10 mm, use M10x25 bolts (supplied). For thicker platform, use locally supplied bolts.Flat washerSpring washerHex bolt (M10 x 20)Screwstwo screws on other sideBowSternCable entryFlatwasherAntenna baseassy.SpringwasherPlatformHex bolt Apply silicone sealant.(M10 x 25or M10 x 20)Transceivermodule5 mm or under: M10x206-10 mm: M10x25over 10 mm: localy supplied bolts

133. ADJUSTMENTThis section provides the information necessary for setting and adjusting the radar sensor, which is carried out from the menu.3.1 Selecting Radar Source1. Open the Radar Installation menu.2. Choose “Radar Source” to show the menu options window.3. Choose “DRS4A” or DRS6A” as applicable.4. Close the Radar Source options window.3.2 Heading AlignmentYou have mounted the radar sensor facing straight ahead in the direction of the bow. Therefore, a small but conspicuous target dead ahead visually should appear on the heading line (zero de-grees).In practice, you will probably observe some small error on the display because of the difficulty in achieving accurate initial positioning of the radar sensor. The following adjustment wil compen-sate for this error.1. Choose “Heading Alignment” from the menu.2. Select a stationary target echo at a range between 0.125 and 0.25 nm, preferably near the heading line.3. Place the cursor on the indication “EBL 1” or “EBL 2” at the bottom left corner, and then press the left-button key at the center of the cursorpad to show the EBL.4. Rotate the RotoKey to bisect the target echo with the EBL.5. Press the left-button key.6. As a final test, move the boat towards a small buoy and confirm that the buoy shows up dead ahead on the radar when it is visually dead ahead.3.3 Setting the Antenna Height1. Select “ANTENNA HEIGHT” from the menu.2. Select the height of the radar sensor above the water surface.
