The following table lists the DCS codes, with the corresponding values (in Hex), which should be programmed
into the ‘DCS Data’ fields for a 23-bit DCS sequence. This does not preclude other codes being programmed.

CTCSS Tone BW
The ‘Sub-Audio Detection Level’ bits (bits 9 to 4) set the minimum CTCSS or DCS signal level that will be
detected. The levels are set according to the formula:
‘Sub-Audio Detection Level’ ´ VDD(A)/8192
[0.61mV per LSB at VDD(A)=5V]
The ‘Sub-Audio Monitor Timeout’ defines maximum time that the sub-audio signal detection can drop out before
loss of sub-audio is asserted. The period is set according to the formula:
‘Sub-Audio Monitor Timeout’ ´ (8.0ms per LSB)
[range 0 to 120ms]
