PrefaceThe TK-7102H transceiver is programmed using a per-sonal computer, a programming interface (KPG-46) and pro-gramming software (KPG-70D).The programming software can be used with an IBM PCor compatible. Figure 1 shows the setup of an IBM PC forprogramming. Group call toneSounds when a group call with the correct DTMF optionsignalling is received, repeats 7 times. You can select yes orno in the Alert tone level setting. Individual call toneSounds when an individual call with the correct DTMFoption signalling is received. You can select yes or no in theAlert tone level setting. Key input error toneSounds when a key is pressed but that key cannot beused. You can select yes or no for the optional feature'swarning tone. Transpond toneSounds when an individual call with the correct DTMFoption signalling is received. For group calls, only the grouptone will sound, not the transpond tone. Pre alert toneSounds prior to the TOT TX inhibit activation. If TOT prealert is set, the tone sounds at the amount of time pro-grammed, before the TOT expires (TOT time – TOT pre alerttime = Pre alert tone sounding time). You can select yes orno for the optional feature's warning tone. Transmit protectionThe final FET is protected against heat while transmittingby making the radio cuts down TX power when the tempera-ture of the final FET becomes higher than reference. Afterthat, if the temperature continue to rise, transmission isstopped. The final FET is also protected against over voltageby having the radio to check that the voltage of power sup-ply connected to the radio is not higher than about 17Vwhen the radio is turned on, otherwise it can not transmit.In both cases when transmission is stopped, a beep willcontinue to sound until the PTT key is released.User modePC mode Data program-ming modePC test mode PC tuning modeClone mode
