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)
Key Lock
In order to prevent accidental frequency change or inadvertent transmission, various
aspects of the VX-4200's keys, and PTT switch, may be locked out. The precise
lockout configuration may be configured using the "User Set" (Menu) mode. See
page 16 for detail.
To activate the Locking feature, press and hold in the [ P4 ] key while turning the
radio on. To disable the Locking feature, repeat this power-on procedure.
