5711 OTHER FUNCTIONSDD DTCS codeSets DTCS code (both encoder and decoder) for DTCSsquelch operation. Total of 104 codes are available.(default: 023)DD DTCS polaritySets DTCS polarities for transmission and reception from“NN,” “NR,” “RN” and “RR.” (default: NN)DD Offset frequencySets the duplex offset frequency within 0 to 20 MHz range.During duplex (repeater) operation, transmit frequency shiftsthe set frequency. (default value may differ depending on operatingfrequency band and versions)DD Tuning stepSelects tuning step from 5, 10, 12.5, 15, 20, 25, 30. 50, 100and 200 kHz for [DIAL] or [Y]/[Z] operation. (default value maydiffer depending on operating frequency band and versions)• Transmit : normalReceive : normal(default)• Transmit : normalReceive : reverse
