If the unit is supplied with less than the specified voltage, it won't operate properly. Keep in mind that when the unit is initially powered on there will be a peak current surge. Check all circuits back to the power source for correct wire gauge and tight connections. Tab.3-2 Power Supply Requirements Supply voltage used Maximum current Allowable range of voltage DC12V 14A 10.2-41.6V DC24V 6A 10.2-41.6V DC24V (for RA55) 15A 18.0-41.6V *A.C. power cannot be used 3.2.2 Fuse Replacement CAUTION: Use only exact replacements.

An ideal position is a location high above the ship's keel line where there is no obstacle all around the scanner. In an actual ship, such an ideal location is limited by various factors. To comply with FCC RF exposure requirements, the radar antenna for this scanner must be installed to provide a separation distance of 1.3 m or more from all persons. (a) Install the scanner as high as possible. Consider the structural support of the location. Will it hold the weight of the scanner? How difficult will it be to get to the scanner for maintenance? (b) Install the scanner away from masts. If the scanner is installed at the same height as a mast, radar waves may be blocked, creating shadow zones or generating false echoes. (c) Install the scanner forward of obstacles. If you can't avoid an obstacle, place the scanner on the bow side of it. When installing the scanner on a mast, position it in front of the mast. (If obstacles cannot be avoided for structural reasons, refer to "Shifting away from obstacles" in Section 3.3.3.) (d) Do not install the scanner near hot or heat-generating items. Do not install the scanner where it may be subjected to smoke or hot air from exhausts or heat from lights. (e) Install the scanner away from other antennas. Keep it as far as possible from the antennas of other electronic equipment. CAUTION Radar scanners will cause interference with radio transceivers. Keep them as far apart as possible (f) Keep the cable length as short as possible. Keep the distance from the scanner to the display unit within the standard cable length of 10 m (or 15m). If you need a longer cable, limit the length to a maximum of 100 m. 3.3.2 Display unit The display unit can be installed in a helm console, bulkhead, or electronics box. Consider these suggestions: (a) (b) (c) (d) A place where you can see the boat's bow when looking straight up from the radar screen. A place where there is no direct sunlight to avoid display temperature buildup. A place where there is good ventilation and minimum vibration. A place where the display unit is more than the minimum safe distance from a magnetic compass as listed in Tab.3-5 below. Tab.3-5 Minimum Safe Distance from Magnetic Compass Scanner unit Display unit RA51/52/53/54/55 INSTRUCTION MANUAL – 05 Standard compass Steering compass 2.0m 1.4m 2.0m 1.4m 11 3.3.3 Shifting away from obstacles • Shifting from keel line By shifting the scanner position from the keel line to the starboard side of the boat, it is possible to move shadow zones to the port side. This makes it possible to keep a clear view to the bow. The distance to be shifted can calculated using the following equation: Ls=0.4R+D/2 [m] (when R<15m) Ls=0.025R+D/2 [m] (when R>=15m) where Ls = distance to be shifted from keel line D = diameter of obstacle on keel line R = distance from scanner to obstacle Scanner Unit Obstacle Ls Keel line Fig.3-1 Shifting from keel line ‚ Obtaining sufficient dip angle Raise the scanner position so that there is a sufficient dip angle θ available between the line of sight from the scanner to the obstacle and the horizontal line. By raising the dip angle above 5°, it is possible to prevent mid- and long-distance shadow zones. The radar cannot detect objects below the line of sight. Horizontal line θ Line of sight Fig.3-2 Obtaining sufficient dip angle 12 RA51/52/53/54/55 INSTRUCTION MANUAL – 05 3.4 Installing Scanner Unit _________________________________ Use a mounting base such as the ones shown in Fig. 3.3, or you can install the scanner directly to a roof or other flat surface. Be certain you keep the water drain tube clear. It's located at the bottom of the scanner unit. Note : If the mounting bracket or surface has a curvature of more than 2mm, use spacers with the mounting bolts to prevent stress on the scanner housing. Do not use an edge that might trap water. Fig.3-3 Mount base Use the template provided with this manual to drill five holes for mounting the scanner. Attach the four bolts and feed the drain tube through the fifth hole. The bolts included with your unit will suffice for mount base thickness of 9 to 14 mm (0.35 to 0.55 in.). If the mount base is thicker or thinner, refer to Tab.3-6. Use a silicone sealant to prevent the bolts from working loose. The housing may be damaged if you use a thread-locking compound. Forward Forward 12φ × 5 (0.47 in.) 214 199 (7.83 in.)

If you need to pass the cable through a wire chase or conduit, tape the scanner side connector to the wire so it doesn't pull off or get hung up. Secure cables in place at intervals of about 40 cm (16"). 3.7.1 Interconnecting cable (RA51 Radome scanner) (See Fig.3-8-2) 1) Be sure that the power is off. Connect the cable to the plug labeled "SCANNER" on the rear panel of the display unit. Be sure to secure the rubber boot around the cable connector rim. 2) Remove the upper part of the radome from the scanner unit. Lift it vertically to avoid bumping it against the antenna. (There are four fixing screws.) 3) Remove the tape securing the antenna. 4) Remove the shield cover located on the backside. (There are four screws.) 5) Remove the cable clamping plate and rubber ring, pass the cable through the opening, replace the rubber ring, and clamp the cable to the scanner unit with screws on the fixing plate. Attach the 7-pin connector to X11 and 9-pin connector to X12 of the printed circuit board. 6) Replace the aluminum cover. Lay the cable shield into the channel machined into the aluminum housing. Be careful that the cable will not get caught up between the main unit and cover. 7) Replace the upper part of the radome being careful not to bump it against the antenna. Make sure that the cover is positioned in the correct direction as shown in Fig.3-7. The upper and lower parts of the radome each have four alignment markings indicating screw positions. 8) Connect the cable to the plug labeled "SCANNER" on the rear panel of the display unit.

However, when the unit is placed close to a radio transceiver and either piece of equipment is not properly grounded, the radar will cause interference. Here are some hints on how to reduce EMI due to radar. (1) Installation Location The display unit, scanner unit and interconnecting cable should be located as far as possible from the transceiver, antenna cable and antenna of the radio. Experiment with various positions of both to see if it improves the condition. (2) Laying Power Supply Cables The best solution is to run separate power wires from each unit directly to the boat's electrical supply source. A connection should be made at the main breaker panel or as close to the generator or battery as possible. Connection A and B are recommended. Connection C should not be used.
