DTCS squelch operation

The tone squelch opens only when you receive a
signal including a matching DTCS code in the FM or
FM narrow mode� You can silently wait for calls from
others using the same tone� Also, a reversed tone
squelch function mutes the squelch when you receive
a signal including a matching DTCS code�
