IC2410.8 VOICE ANSWER BACK FUNCTION OPTION UT-66 AND UT-55 ARE NECESSARY 1. The radio needs to be switched to sub band remote mode. 2. Operating frequency of main band will be announced from sub band transmitted by sending remote control code of "D" "C". 3. During this answer back operation, main and sub bands were swapped but as soon as answer back has been done, it will be resumed. The radio main band will be the talk band. The radio sub band will be the band the HT controls and talks on. to enter EXTERNAL DTMF REMOTE control press B password # default B000# - XBAND REPEAT ON HOLD (BAND) & (SET) UNTIL FLASHING "L" - XBAND REPEAT OFF PUSH SET - REMOTE XBAND ON PUSH "D" THEN "B" THEN "*" ON KEYPAD REMOTE DTMF - REMOTE XBAND OFF ENTER B password # OR B000# DEFAULT - REMOTE SUB BAND PUSH "D" THEN "C" ON REMOTE DTMF VOICE READBACK KEYPAD to exit EXTERNAL DTMF REMOTE control be sure that remote XBAND is off B password # and press B password * default B000* NOTE: Please note that remote XBAND must be off to control all transceiver functions including voice readback.
