The DC power connector for the FT-950 must only be connected to a DC source providing 13.8 Volts DC(±10 %), and capable of at least 22 Amperes of current. Always observe proper polarity when making DC connection:The RED DC power lead connects to the Positive (+) DC terminal.The BLACK DC power lead connects to the Negative (–) DC terminal.We recommend the use of the FP-1030A AC Power Supply. Other models of power supplies may be used with the FT-950,but the 13.8 VDC input voltage, 22-Ampere current capability, and DC cable polarity guidelines described above must bestrictly followed.Note that other manufacturers may use the same type of DC power connections as does your FT-950 transceiver, however,the wiring configuration may be different from that specified for your transceiver. Serious damage can be caused if im-proper DC connections are made; consult with a qualified service technician when in doubt.Permanent damage can result when improper supply voltage, or reverse-polarity voltage, is applied to the FT-950.The Limited Warranty on this transceiver does not cover damage caused by application of AC voltage, reversepolarity DC, or DC voltage outside the specified range of 13.8 V ±10 %. When replacing fuses, be certain to use a fuse ofthe proper rating. The FT-950 requires a 25 A blade fuse.ADVICE: Do not position the FT-950 in a location with direct exposure to sunshine. Do not position the FT-950 in a location exposed to dust and/or high humidity. Ensure adequate ventilation around the FT-950, to prevent heat build-up and possible reduction of performance due tohigh heat. Do not install the FT-950 on an unstable desk or table. Do not place in a location where objects may fall onto it from above. To minimize the possibility of interference to home entertainment devices, take all precautionary steps including sepa-ration of TV/FM antennas from Amateur transmitting antennas to the greatest extent possible, and keep transmittingcoaxial cables separated from cables connected to home entertainment devices. Ensure that the DC power cord is not subject to undue stress or bending, which could damage the cable or cause it to beaccidentally unplugged from the rear panel DC IN jack. Be certain to install your transmitting antenna(s) so they cannot possibly come in contact with TV/FM radio or otherantennas, or with power or telephone lines.Use a short, thick, braidedcable to connect your sta-tion equipment to the bur-ied ground rod (or alterna-tive earth ground system).I NSTALLATION AND I NTERCONNECTIONS
