TH-F6A/F7E37• To adjust “AM radio” or “HF” band, the bar antenna mustbe activated (factory default: ON).H. APC adjustment1) Display the [P: BAf1] item.2) Set the A band to the operation band.3) Set power supply voltage to 6 V.4) Set display frequency and transmission power as shownin the “Frequency/Power Adjustment Points” tablebelow.5) Press [PTT] and turn the encoder during transmissionto increase or decrease transmission power and changethe “real-time value”.6) Press [MNU] key to set the “real-time value” in theEEPROM.7) Set the item display to “f2” and “f3” and adjust allfrequency/power adjustment points.8) Display the [P: 7f1] item.9) Set the power supply voltage to 7.4 V and perform steps4 to 7 above.10)Display the [P: 13f1] item.11)Set the power supply voltage to 13.8 V.12)Set transmission power to H and perform steps 4) to 7).For any band that does not requires three-pointadjustment, enter the same data at all three points.Band Power Frequency adjustment point• Frequency/power/power supply voltage adjustment pointsPower supplyvoltageDry cell 144MHz H 3 points (f1, f2, f3)6[v] L 3 points (f1, f2, f3)EL 3 points (f1, f2, f3)220MHz H 3 points (f1, f2, f3) K destination onlyL 3 points (f1, f2, f3) K destination onlyEL 3 points (f1, f2, f3) K destination only400MHz H 3 points (f1, f2, f3)L 3 points (f1, f2, f3)EL 3 points (f1, f2, f3)Lithium ion 144MHz H 3 points (f1, f2, f3)7.4[v] L 3 points (f1, f2, f3)EL 3 points (f1, f2, f3)220MHz H 3 points (f1, f2, f3) K destination onlyL 3 points (f1, f2, f3) K destination onlyEL 3 points (f1, f2, f3) K destination only400MHz H 3 points (f1, f2, f3)L 3 points (f1, f2, f3)EL 3 points (f1, f2, f3)13.8[v] 144MHz H 3 points (f1, f2, f3)L 3 points (f1, f2, f3)EL 3 points (f1, f2, f3)ADJUSTMENT• Frequency/mode adjustment points• To adjust “AM radio” or “HF” band, the bar antenna mustbe activated (factory default: ON).G.
