What You
Hear on a
Channel
14 Basic Operation
Your radio is fitted with a transmit timer that limits
the amount of time you can transmit continuously.
If the radio gives three beeps, the transmit timer is
about to expire. You must release the PTT before
you can transmit again. The radio may be pro-
grammed to prevent transmission for a period after
the transmit timer has expired.
What traffic you hear on a channel depends on how
your radio was programmed. Your radio can be pro-
grammed so that you hear all conversations on a
channel, or your user group may be segregated from
others, using various types of signaling (CTCSS,
DCS, 2-tone or 5-tone).
When special signaling is active, you are not able to
hear other groups talking on the current channel
unless the monitor function is active (see "Monitor"
on page 15). If the channel is busy, the
tor appears in the control head display.
There are three types of muting control which may
screen your calls:
I CTCSS and DCS mute,
I selective call mute, and
I RF squelch.
Note: RF squelch is always programmed to
operate in your radio, but the CTCSS, DCS
and selective call mutes are dependant on
the way your radio is programmed.

CTCSS (continuous tone controlled subaudible sig-
naling) and DCS (digitally coded squelch) signaling
use subaudible tones to isolate your calls, so that
