about 1-1/2 to 2 inches away from your mouth. Release the PTT switch to receive.
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 generate
a short beep three times and indicate “*ERROR *” 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.

VX-4200 SERIES OPERATING MANUAL6
Automatic Time-Out Timer
If the selected channel has been programmed for automatic time-out, you must limit
the length of each transmission. While transmitting, a beep will sound 10 seconds
before time-out. Another beep will sound just before the deadline; the red “TX”
indicator will disappear and transmission will cease soon thereafter. To resume trans-
mitting, you must release the PTT switch and wait for the “penalty timer” to expire
(if you press the PTT switch before this timer expires, the timer restarts, and you will
have to wait another “penalty” period)
