BUSY CHANNEL INDICATION
The yellow Busy Channel Indicator glows if
there is carrier activity on the selected
channel. If the selected channel is a Code
Guard channel and the proper Code Guard
value is not detected, the Busy Channel
Indicator remains on for the duration of the
carrier activity and no message is heard.
During Scan and Priority Scan operation, the
Busy Channel Indicator glows when activity is
detected on any channel on the Scan List.
When scanning or priority scanning Code
Guard channels with the Squelch knob in the
Code Guard position and activity has been
detected, the Busy Channel Indicator glows
for the time period necessary to determine if
the proper Code Guard value has been
received. This will cause the Busy Channel
Indicator to flash at various rates.
BUSY CHANNEL LOCKOUT
The Busy Channel Lockout feature applies
only to those channels programmed with a
receive Code Guard value. When carrier
activity is detected on the channel selected,
the radio checks the receive Code Guard
value. If the proper Code Guard value is
present, the radio can transmit on that
channel, even if the Squelch knob is in the
Code Guard position.
If the radio detects an incorrect value or
carrier activity only, the transmitter is disabled.
If an attempt is made to transmit, an alert tone
will be generated and the display will show the
word
BUSY
until the channel becomes
available or the PTT switch is released,
whether the Squelch knob is in or out of the
Code Guard detent.
Channels not programmed with a receive
Code Guard value can be used to transmit
regardless of carrier activity.
