IC24AT.5 FUNC + 7 = Priority mode on/off (operation dependent on current mode) FUNC + 8 = Set mode (several different functions, press A to exit) FUNC + 9 = Real time clock and timer functions (press PTT to exit) FUNC + A = Memory to VFO transfer FUNC + B = Memory Write FUNC + C = Split operation (cross band full duplex) FUNC + D = Lock mode / Cross Band Repeat disable FUNC + * = Scan programmed limits (down) FUNC + # = Scan programmed limits (up) FUNC + 5 + D = Cross Band Repeat enable (split mode must be on!) Diode D14 (right diode on CPU board) must be removed to enable the use of this function) FUNC + MONI = RX/TX light enable / disable FUNC + H/L/DTMF = Select DTMF Autodialer memory Func + VFO knob = Change frequency/memory channel (according to dial set, see FUNC+0) Func + LIGHT = Lock light on (don't time out) H/L/DTMF + VFO knob = Change output power (4 power levels when using 13.8 vdc) The following key combinations selects "power on modes". Start with the radio OFF, then hold down the indicated keys, and continue to hold them while turning the power ON. Some 'modes' override others. LIGHT + * = PTT enable LIGHT + 0 = PTT Disabled (inhibits the transmitter, good security method) LIGHT + 1 = 1 MHz digit set (4 digit frequency entry) LIGHT + 2 = 10 MHz digit set (5 digit frequency entry) LIGHT + 3 = 100 MHz digit set (6 digit frequency entry) LIGHT + 4 = Scan pause until signal disappears LIGHT + 5 = Scan pause for 10 seconds LIGHT + 6 = ????
