REPEAT MODE 21.1 ANALOG If the received CTCSS/DCS matches the programmed CTCSS/DCS, the radio transmits the programmed carrier frequency and CTCSS/DCS. Hang time is programmable (0-9.9sec), through the “Miscellaneous” tab of the 91-1480CD software. 22.2 DIGITAL Matching NAC (Network Access Code); If the programmed NAC matches the received NAC it allows the radio to repeat. The programmed NAC and TGID (Talk Group Identification), is transmitted. $F7F in RX NAC If the RX NAC is $F7F, all incoming signals are repeated with the same NAC and TGID as received. $F7F in RX NAC w/ Through OFF; If the RX NAC is $F7F, receives all incoming signals and transmits the programmed NAC and TGID. Note: Hang time is programmable (0-9.9 seconds), through the “Miscellaneous” tab of the Base Tech III (91-1480-CD) software. 22.3 MIXED In Mixed mode, the radio receives both Analog and Digital signals automatically. Individual channel programming can be combined as described in a) and b) above. If the radio receives analog, it transmits analog, if it receives digital, it transmits digital. 22 www.midlandradio.com Version 5.0 680-090-2042 23. BASE MODE 23.1 ANALOG If the received CTCSS/DCS matches the programmed CTCSS/DCS, the radio’s receiver will open. The MON key may be pressed to bypass any tone signaling. 23.2 DIGITAL Matching NAC (Network Access Code); If the programmed NAC/TGID matches the received NAC/TGID, the receiver will open. Pressing SHIFT + MON switches between Selective SQL and Normal SQL mode. $F7E in RX NAC If the NAC is set for $F7E, the radio should receive any incoming NAC. 23.3 MIXED In Mixed mode, the radio receives both Analog and Digital signal automatically. Channel programming can be combined as described in 23.1 and 23.2 above on an individual channel. 24. REMOTE CONTROL The BASE TECH III can be controlled remotely by pulling pin 24 of the EXT OPTION 25 pin D-sub connector to a low level. Local operation is restored when pin 24 goes HI. In the Remote Mode only channels 1-16 can be controlled. Also when in Remote Mode Front Panel MON and Channel Selection is disabled.
