BUSY LOCKOUT
When using Silent mode with CTCSS/DCS, your radio's receiver remains quiet to
all signals outside your CTCSS/ DCS group. As a result, if you do not notice when
others are transmitting on your channel you could accidentally transmit over the
top of them.
The Busy Lockout function detects when others outside your CTCSS/DCS group are
transmitting on the channel and prevents your radio from transmitting over them.
If you press the PTT when the channel is busy the radio will emit a warning beep
and the
icon won't be displayed. If this happens, look for the
the display as an indicator that the channel is in use. If the channel is busy, simply
wait until the channel is clear and press the PTT again.
To enable or disable busy lockout:
1.
Press the MENU key.
2.
Navigate through the menu to select RADIO SETTINGS > BUSY
LOCK.
Use the MENU key to turn the function ON or OFF.
NOTE:
A 'Busy Lockout Override with CTCSS Match' option is available through
the XRS Connect App. When this option is enabled, Busy Lockout will not prevent
you from transmitting over the top of another signal where their CTCSS/DCS code
matches yours (i.e. The signal is from a member of your group).
Your radio has a Selective Calling system known as SelCall that operates like a
telephone. Your radio is pre-programmed with its own unique SelCall Identification
number. If this number is called by another radio, your radio will beep to alert you.
If you do not want to hear any other activity while waiting on a channel, you can
select the QUIET mode. Your radio will then remain quiet to all incoming signals
until your SelCall number is called.
You can store up to 20 of your most frequently called SelCall numbers in memory
and each number can be labelled for easy identification.
