If the Busy Channel Lockout feature has been programmed on a channel, the
radio will not transmit when a carrier is present. Instead, the radio will gener-
ate a short beep three times and the
VX-4600CB
indicates “
CH BUSY
” on
the display. Release the
PTT
switch and wait for the channel to be clear of
activity.
If CTCSS or Digital Coded Squelch (DCS) Lockout has been programmed on
a channel, the radio can transmit only when there is no carrier being received
or when the carrier being received includes the correct CTCSS tone or DCS
code.

To activate the Locking feature, press and hold in the [
P1
