Receiving a Voice Call
If CTCSS/CDCSS, 2-Tone, DTMF, HDC1200 or HDC2400™
signaling is set for the current channel, a signaling match
is required on an incoming signal for the radio to unmute.
If signaling is not set, the radio can receive calls from all
users operating on the same frequency. You may adjust
the volume through the
Volume Control
knob.
