10-6 DCS (DIGITAL CODED SQUELCH)
DCS function is used to decode a selected digital code that uses 23 bit code data sent lower than the
voice frequency. The data speed is 134.3 bit/sec in NRZ (Non-Return-Zero) format FM modulation.
(Note: This function operates only in the FM mode with less than 30 kHz of IF-BW.)
To activate the function, perform the following steps:
1. Press the [F] key and then the [1] key.
2. Press the [▼] key to select “SQL” parameter in reverse contrast.
3. Rotate the dial knob to select “DCS” in reverse contrast.
4. Press the [▼] key to select “DCS” parameter in reverse contrast.
5. Rotate the dial knob to select the desired DCS code from the list below. To set DCS off, select “OFF”.
Selecting “SRCH” will activate DCS search function.
6. Press the [ENT] key to accept the entry and return to a standard display.
Alternatively, press the [CLR] key to abort entry.
