12 FTM-10R O PERATING M ANUALINSTALLATIONMOBILE I NSTALLATIONThe FTM-10R 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 easilyaccessible, using the supplied Mobile Mounting Bracket.The transceiver may be installed in almost any location, but should not be positioned neara heating vent or anywhere where it might interfere with driving (either visually or me-chanically). Make sure to provide plenty of space on all sides of the transceiver so that aircan flow freely around the radio’s case.An antenna and an antenna cable are not included in the box. Purchase them separately toaccommodate your transceiver installation.U The DC power cable draws a large current when transmitting. The power cable shouldbe wired as short as possible, and connected directly to the battery. (Do not use thecigarette lighter socket for power connections).U Never remove the fuse holders from the DC cablesU Never connect the transceiver directly to a 24 V battery.U Select a low-loss coaxial cable to connect the transceiver with the antenna. Use theshortest length possible.U Select a quality, high efficiency VHF/UHF antenna, and mount it in a good location onthe car to obtain the maximum performance from the transceiver. (NOTE: An antennadesigned with a matching device that forms a low DC resistance to ground may havepoor reception on the AM broadcast band.)U The antenna depends on good grounding to realize maximum performance. Contactyour dealer for information on transceiver and antenna installation.U If alternator noise exists, use a line filter in the DC power cable connection.IMPORTANT: Select a location which can support the weight of the FTM-10R trans-ceiver and does not interfere with your driving.
