4811SET MODES12345678910111213141516171819DD DTCS codeSelects DTCS (both encoder/decoder code) for DTCSsquelch operation. Total of 104 codes are available.• 023–754: 023 (default)DD DTCS polaritySelects DTCS polarities for transmission and reception from“nn (default),” “nR,” “Rn” and “RR.” (n: normal/R: reverse)DD Tuning stepSelects tuning step from 5, 10, 12.5, 15, 20, 25, 30 and50 kHz for [YY]/[ZZ] or [VOL] (When [VOL] is assigned as tuningdial ) operation. (default value may differ depending on trans-ceiver types and versions)DD Offset frequencySets the duplex offset frequency within 0 to 20 MHz range.During duplex (repeater) operation, transmit frequency (or re-ceive when reverse function is set to ON) shifts the set fre-quency. (default value may differ depending on transceivertypes and versions)DD Reverse functionTurns the reverse function ON and OFF (default).Reverse function OFF Reverse function ON
