When a signal with the correct tone or code is received, the
transceiver’s mute is released and received audio sounds.

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.
