NOTE:
• The DTCS squelch operation on sub-band does not func-
tion during DTCS transmission because the same en-
coder/decoder circuit is being used for both main and
sub-bands. Tone squelch operation on sub-band may not
be performed correctly during DTCS transmission.
• The tone/DTCS code squelch opens sometimes when
other stations communicate using an adjacent tone fre-
quency or in a DTCS code.
• The tone/DTCS code squelch can be operated on FM or
FM-N mode only.
