Quiet Call (CTCSS) - Programming a Quiet Call code
allows you to screen out transmissions that do not
carry your code. Your code is broadcast when you
press the PTT to make a call.
Quiet Call Encode Only - The Quiet Call code
programmed for the channel is transmitted with your
calls. However, no Quiet Call code is programmed
for receive mode, allowing all traffic on the channel to
be heard.
Receive Frequency - The radio frequency that
receives broadcasts from other units.
Receive Squelch Tone - The receiving radio beeps at
the end of each received transmission.
Squelch Tightener - This feature reduces distant "co-
channel" or other interference for channels that are
not programmed with Quiet Call. Carrier squelch is
set for maximum sensitivity at the factory, but may be
adjusted to mute weak signals
Transmit Frequency - The radio frequency that
broadcasts to other units.
Transmit Time Out Timer - This feature automatically
shuts off the transmitter (ending your call) if you hold
down the PTT button continuously for 60 seconds.
The radio sounds a tone when the transmitter shuts
off.
Turn On To Medium Volume Level - The volume level
is at mid-range when the radio is first turned on.
Normally, the volume level is low when the radio is
turned on.
