1. MOUNTING 1.1 Mounting of Transceiver Unit General mounting considerations The transceiver unit can be mounted on the overhead, a bulkhead, on a tabletop, or in a console (flush mounting). When selecting a mounting location keep the following points in mind: • Make sure the location is strong enough to support the unit under the conditions of continued vibration and shock normally encountered on the boat. Where necessary, reinforce the mounting location by lining block or doubling plate.
Console mounting Mounting considerations In addition to the general mounting considerations mentioned on the previous page, keep the following points in mind when selecting a mounting location: • Select a place where the LCD can be easily viewed, keeping in mind the LCD viewing angle is as shown in Figure 1-2. • Leave sufficient space around the unit to permit dispersal of heat after a long transmission. How to mount the transceiver unit in a console This method does not require any additional kit.
1.2 Mounting of Antenna Coupler The antenna coupler is installed between the antenna and the transceiver, and tunes the antenna to the transmitter. Mounting considerations The splashproof construction of the antenna coupler permits installation indoors or outdoors. When selecting a location, keep in mind the following points: • All wires from the coupler to the antenna radiate radio energy.
Mounting the antenna coupler Mounting methods The antenna coupler can be fixed to the floor, bulkhead, or on the overhead. For mounting on the bulkhead, floor or overhead, fix the coupler with either tapping screws or M6 nuts, bolts and washers.
How to mount the antenna coupler For thin bulkhead, use nuts, bolts and and washers instead of tapping screws.
1.3 Ground System A good antenna can work well only when it is connected to an efficient rf ground. Without a good ground system, the full potential of this radio cannot be realized. CAUTION Ground the equipment to prevent electrical shock and mutual interference. Ground for metallic hull Run a copper strap (option or local supply) between the earth terminal on the antenna coupler and the ship’s superstructure. The length of the copper strap should be as short as possible.
1.4 Mounting of Antenna About antennas The antenna plays the most important role in radio communication. If it cannot receive or transmit effectively because of improper installation, even the most sophisticated transceiver will be rendered useless. There are various types of SSB antennas. The most commonly used are a long wire and a whip. Whatever antenna is to be used, the antenna coupler can tune a long wire or whip whose total length is 6 to 15 meters.
Typical antenna installations Long wire antenna Whip antenna Ship station Power boats On ship stations, the long wire antenna is spanned between supporting structures. The length of the horizontal wire should be between 6 and 15 meters. And the length of the vertical wire should be no less than 5 meters, the longer the better transmission. On power boats, selection of a mounting location for a whip antenna is much easier, since there is no mast or deck fixture to worry about.

3. WIRING OF OPTIONAL EQUIPMENT 3.1 NBDP Terminal DP-6 The NBDP Terminal connects to the REMOTE connector on the FS-1503. It has a remote control function which automatically sets class of emission and frequency data at the FS-1503. Remarks on connection Connect the NBDP Terminal to the FS-1503 with a 13-pair twisted cable. For the cable with no connectors, attach connector types SRCN (at FS-1503) and D-sub (at DP-6). For cable with Dsub connector, connect the SRCN connector at the FS-1503 side.
3.3 Remote Station RB-500 Connect to the REMOTE connector on the FS-1503. If more than two RB-500s or DSC, NBDP are to be installed, connect them via the Distributor DB-500. Necessary parts Requires REMOTE-B Kit (current loop) for connection of a single remote station or REMOTEA Kit when the DB-500 is connected. Install the board following the illustration on page 3-3.

3.6 BK (Break-in) Connection BK (Break-in) connection is necessary when the FS-1503 is installed together with an HF receiver or transceiver. The BK circuit functions to mute the receiver when it and the FS-1503 are operated together. With no BK connection, the receiver may generate unwanted noise or its front end may be damaged by strong signals when the radio is transmitted. Necessary parts The BK function requires the CONTROL Kit, which consists of the CONTROL Board, connector assy., gasket and washer.
3.8 SW Regulator (SW REG board) The FS-1503 is supplied with negative ground. If necessary, to float the battery negative line, the SW REG Kit is available. Install the kit following the illustration below. J5 J6 PA/FIL BOARD 05P0667 2 Fasten SW. REG Board with five pan head screws-B (M3X8). 4 Connect CONNECTOR ASSY.

3.9 Dummy Load The dummy load enables testing of the two-tone alarm. Install the board following the figure below. CHANGE SYSTEM SETTING 9917 to 1. W4 should not touch TB4 or W3. TB4 ANT Fasten wire with cable tie. Gap between inner wall and wire should be more than 15 mm. W4 WIRE ASSY. Separare these wires: Bend crimp-on lug attached to TB1 upward; bend crimp-on lug attached to TB3 downward. W3 WIRE ASSY. NOTICE W6 WIRE ASSY. Separate wire assemblies W3 and W4 more than 15 mm from each other.
3.10 Floating Ground Radiotelephone (FS-5000, etc.) Connect the FS-1503 to the floating ground radiotelephone with a connection cable whose diameter is 0.75 mm2 or larger (3C cable or equivalent).
4. INSTALLATION CHECK 4.1 lnstallation Checks After completing the installation, check the FS-1503 and all equipment connected to it for proper connection and operation.
Performance If no problems were found in the preceding sections, then turn on the transceiver and check it for proper performance. Receiver 1. Turn on the loudspeaker. 2. Turn off the squelch. 3. Check that all the bands can be received clearly. If signal strength is too low or there is too much noise return to “Visual check” and recheck. Double check the antenna and ground. If there is no trouble, proceed to the next step.
