  • Page 8: Installation

    Do not install the transceiver on top of another heat-generating device (such as a power supply or amplifier), and do not place equipment, books, or papers on top of the FT-1907R. Avoid heating vents and window locations that could expose the transceiver to excessive direct sunlight, especially in hot climates.

  • Page 9: Safety Information

    AFETY NFORMATION The FT-1907R is an electrical apparatus, as well as a generator of RF (Radio Frequency) energy, and you should exercise all safety precautions as are appropriate for this type of device. These safety tips apply to any device installed in a well-designed amateur radio station.

  • Page 10: Antenna Considerations

    NTENNA ONSIDERATION The FT-1907R is designed for use with antennas presenting an impedance of near 50 Ohms at all operating frequencies. The antenna (or a 50 Ohm dummy load) should be connected whenever the transceiver is turned on, to avoid damage that could otherwise result if transmission occurs accidentally without an antenna.

  • Page 11: Mobile Installation

    NSTALLATION OBILE NSTALLATION The FT-1907R must only be installed in vehicles having a 13.8 Volt negative ground elec- trical system. Mount the transceiver where the display, controls, and microphone are easily accessible, using the supplied MMB-36 mounting bracket. The transceiver may be installed in almost any location, but should not be positioned near a heating vent nor anywhere where it might interfere with driving (either visually or me- chanically).

  • Page 13: Base Station Installation

    NSTALLATION TATION NSTALLATION The FT-1907R is ideal for base station use as well as in mobile installations. The FT- 1907R is specifically designed to integrate into your station easily, using the information to follow as a reference. AC Power Supplies Operation of the FT-1907R from an AC line requires a power source capable of providing at least 11 Amps continuously at 13.8 Volts DC.
