SAFETY INSTRUCTIONS WARNING Radio Frequency Radiation Hazard The radar scanner emits electromagnetic radio frequency (RF) energy which can be harmful, particularly to your eyes. Never look directly into the scanner aperture from a close distance while the radar is in operation or expose yourself to the transmitting scanner at a close distance. Distances at which RF radiation levels of 100 and 10 W/m2 exist are given in the table below.
WARNING WARNING Do not open the equipment unless totally familiar with electrical circuits and service manual. ELECTRICAL SHOCK HAZARD Be sure that the power supply is compatible with the voltage rating of the equipment. Connection of an incorrect power supply can cause fire or equipment damage. The voltage rating of the equipment appears on the label above the power connector. Only qualified personnel should work inside the equipment. Wear a safety belt and hard hat when working on the scanner unit.

EQUIPMENT LISTS Standard Supply Name Scanner Unit Display Unit Type Code No.
1. MOUNTING 1.1 Mounting Methods for Scanner Unit • The scanner unit is generally installed either on top of the wheelhouse or on the radar mast on a suitable platform. Locate the scanner unit where there is a good allround view. Any obstruction will cause shadow and blind sectors.
1.3 Fastening the Radiator to the Radiator Bracket For your reference, scanner installation materials list appears in the packing lists at the back of this manual. anticorrosive sealant. Fasten the scanner radiator to the radiator bracket with the radiator fixing bolts, flat washers and spring washers. Scanner radiator 1. Remove the radiator cap from the radiator bracket. 2.
2. Lay the scanner unit on the mounting platform, orienting it as shown in Figure 1-6. 4. Pass flat washers, spring washers and nuts onto hex bolts. Fasten by tightening nuts. Do not fasten by tightening the hex bolts; seal washers may be damaged.
Fixing holes inside szcanner unit 1.5 Display Unit Mounting This method requires removal of the RF unit in the scanner unit to access inside fixing holes. Use hex head bolts, flat washers, spring washers and nuts (local supply) to mount the scanner unit, confirming lengh of bolts. Mounting considerations 1. Loose four scanner bolts to open the scanner unit. Refer to Figure 11 for location. Hex head bolt M8X25 SUS 2pcs. Upper chassis RFunit Hex head bolt M10X20 SUS 4pcs. Spring Washer M10 SUS 4 pcs.
2. CONNECTIONS 2.1 Connecting the Signal Cable Only the signal cable runs from the display unit to the scanner unit. In order to minimize the chance of picking up electrical interference, avoid where possible routing the signal cable near other onboard electrical equipment. Also, avoid running the cable in parallel with power cables. Pass the cable through the hole and apply sealing compound around the hole for waterproofing. 3. Unfasten the cable gland assembly (plate, gasket, flat washer). 4.
7. Unfasten four screws shown in the figure below. Four screws 9. Connect the signal cable to the RTB Board (03P9249), referring to the interconnection diagram and the figure below. Note that connector VH2P is not used. 10.Attach three EMI cores to the signal cable as shown below. J821 VH9P J824 NH13P Lead in cable here. Figure 2-5 Scanner unit chassis, cover opened EMI core RFC-13 8. Pass the signal cable through the cable protector. Cable protector J823 VH4P Clamp Route cable along here.
Connection procedure Heading sensor connection 1. Connect the power cable to the power cable connector on the rear of the display unit. Heading signal can be connected to the “HDG” connector. You will need a heading sensor cable. The following cables are optionally available. 2. Connect the signal cable to connector DJ1 on the rear of the display unit. 3. Run a ground wire (local supply) between the ground terminal on the rear of the display unit and the ship’s superstructure. 2.
2.4 Exchange of Fuse for 24/32V Power Supply The power cable comes with a 10A fuse in its the fuse its holder. This fuse is for use with a 12V DC power supply. For 24V/32V DC power supply, replace the fuse with the 5A fuse (supplied) and attach 5A label (supplied) to fuse holder. CAUTION Use the proper fuse. Use of an improper fuse can damage the equipment and void the warranty. 2.
3. ADJUSTMENT This section covers adjustment of the radar after installation. You will need to 3.2 Adjusting Tuning/Video • adjust tune/video amplifier level Do the following to automatically adjust tuning and video amplifier level input. • enter antenna height 1. Press the [STBY/TX] key to transmit. • align heading • adjust sweep timing WARNING • adjust main bang suppression • select STC curve • set a dead sector, and • confirm magnetron heater voltage.
3.4 Aligning Heading (Adjustment sector: 0~359.90) You have mounted the scanner unit facing straight ahead in the direction of the bow. Therefore, a small but conspicuous target dead ahead visually should appear on the heading marker (zero degrees). In practice, you will probably observe some small bearing error on the display because of the difficulty in achieving accurate initial positioning of the scanner unit. The following adjustment will compensate for this error. 1.
[ Sweep Timing Adjustment ] Use omnipad to straighten target and press ENTER key. Correction 0.000 nm Figure 3-5 Sweep timing adjustment message 4. Operate the trackball to straighten the target selected at step 2, and then press the [ACQ/ENTER] key. 1. Select “13. STC Curve” from the Installation Setup menu and press the [ACQ/ENTER] key. 2. Select STC curve desired; Sharp: The effective range of the [A/C SEA] control is relatively short. Std: Between Sharp and Gentle.
3.9 Checking Magnetron Heater Voltage Magnetron heater voltage is formed on the MD Board of the scanner unit, and is preadjusted at the factory for use with any length of signal cable. Therefore no adjustment is required. However, check magnetron heater voltage as follows: 1. Turn on the radar and leave it in standby. 2. Open the scanner cover. 3. Unfasten two screws to remove the RF section cover. DANGER ELECTRICAL SHOCK HAZARD This check is done with the power on — DO NOT touch the magnetron.
4. INSTALLATION OF ARP-10 (OPTION) (3) Faster the ARP-10 Board to the chassis with three pan head screws and springs washers. NOTICE This option is not available with 48 rpm scanner unit. Front Spring Washer M3 3 pcs. $ Spacer SQ-20 3 pcs. 4.1 Necessary Parts Name Type $ Code No. Qty Pan Head Screw M3 x 8 3 pcs.
