1 GENERAL INFORMATION The Vertex Standard GX3500S is a VHF/FM transceiver designed for use in the frequency range of 156.025 to 163.275 MHz. The GX3500S can be oper- ated from 11 to 16 VDC and has a switchable RF output power of 1 watt or 25 watts. The GX3500S is capable of DSC (Digital Selective Calling) Class D operation and an Enhanced second station RAM+ mic (CMP25 remote-control speaker/ microphone with display). Class D operation allows continous receiving of Digi- tal Selective Calling f

4 SAFETY / WARNING INFORMATION This radio is restricted to occupational use, work related operations only where the radio operator must have the knowledge to control the exposure conditions of its passengers and bystanders by maintaining the minimum separation dis- tance of 0.6 m (2 feet). Failure to observe these restrictions will result in exceeding the FCC RF expo- sure limits. Antenna Installation: The antenna must be located at least 0.6 m (2 feet) away from passengers in order to comply w

7 GETTING STARTED 7.1 ABOUT VHF RADIO The radio frequencies used in the VHF marine band lie between 156 and 158 MHz with some shore stations available between 161 and 163 MHz. The ma- rine VHF band provides communications over distances that are essentially “line of sight” (VHF signals do not travel well through objects such as buildings, hills or trees). Actual transmission range depends much more on antenna type, gain and height than on the power output of the transmitter. On a fixed mount 2

7.3 COAXIAL CABLE VHF antennas are connected to the transceiver by means of a coaxial cable – a shielded transmission line. Coaxial cable is specified by it’s diameter and construction. For runs less than 20 feet, RG-58/U, about 1/4 inch in diameter is a good choice. For runs over 20 feet but less than 50 feet, the larger RG-8X or RG-213/U should be used for cable runs over 50 feet RG-8X should be used. For installa- tion of the connector onto the coaxial cable refer to the figure below. Adapte

8 INSTALLATION 8.1 LOCATION The radio can be mounted at any angle. Choose a mounting location that: • is far enough from any compass to avoid any deviation in compass read- ing due to the speaker magnet • provides accessibility to the front panel controls • allows connection to a power source and an antenna • has nearby space for installation of a microphone hanger • the antenna must be mounted at least 3 feet from radio Note: To insure the radio does not affect the compass or radios performan

2. Connect the red power wire to a 13.8 VDC ±20% power source. Connect the black power wire to a negative ground. 3. If an optional remote extension speaker is to be used, refer to next section for connections. 4. It is advisable to have a Certified Marine Technician check the power output and the standing wave ratio of the antenna after installation. 8.3 ACCESSORY CABLE White: External speaker (+) Shield: External speaker (–) Red: PA speaker (+) Shield: PA speaker (–) Blue: NMEA IN (+) from GP

8.9 OPTIONAL MMB-84 FLUSH MOUNT INSTALLATION 1. To assist in flush mounting, a template has been included. Use this tem- plate to find the mounting location. 2. Use the template to mark the location where the rectangular hole is to be cut. Confirm the space behind the dash or panel is deep enough to accom- modate the transceiver (at least 6 inches or 15 cm deep). There should be at least 1/2 inch (1.3 cm) between the transceiver’s heatsink and any wiring, cables or structures. 3. Cut out the re
