Yaesu Ft 857D Hidden Menu Plus The 6Providing coverage of the 160-10 meter bands plus the 6 m, 2 m, and 70 cm bands, the FT-857 includes operation on the SSB, CW, AM, FM, and Digital modes, yielding the most comprehensive performance package available for mobile and field operation.The display includes bar-graph indication of power output, ALC voltage, SWR, modulation level, andor signal strength.Also included are a number of operating status icons, as well as the function displays for the three operating function keys ( A, B, and C ). It is presumed that you possess technical knowledge and conceptual understanding consistent with your status as a licensed radio amateur. Please take some extra time to make certain that the important safety and technical requirements detailed in this chapter are followed closely. Confirm that all controls and switches work freely, and inspect the cabinet for any damage. Gently shake the transceiver to verify that no internal components have been shaken loose due to rough handling during shipping. Be certain to save the shipping carton, especially if there are any punctures or other evidence of damage incurred during shipping; if it is necessary to return the unit for service or replacement, use the original packing materials but put the entire package inside another packing carton, so as to preserve the evidence of shipping damage for insurance purposes. The FT-857 should not be used in an environment where the ambient temperature exceeds 140 F (60 C). These safety tips apply to any device installed in a well-designed amateur radio station. Do not install a directional antenna in any location where humans or pets. Pull over to the side of the road, whether dialing manually. Just route the cable into the appropriate channel provided, as shown in the illustration. Direct connection to the battery also provides the best voltage stability. ![]() Be certain to solder the connections at the splice securely, and provide ample insulation for the soldered splice (heat shrink tubing plus black electrical tape work well). If the battery is not charged sufficiently to maintain at least 11 Volts at the radio, erratic operation or shut-down may occur. The Limited Warranty on this transceiver does not cover damage caused by application of AC voltage, reversed polarity DC, or DC voltage outside the specified range of 13.8V 15. Never attempt to connect the FT-857 to a 24-Volt battery system. A good ground system can contribute to station efficiency in a number of ways. The information presented below is intended only as a guideline. Due to unexpected resonances which may naturally occur in any location, improper communication system performance may result from insufficient grounding. The FT-857 includes extensive filtering designed to minimize the chance of such problems; however, random currents set up by insufficient RF grounding can nullify such filtering.
