Transmit 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. On the
VX-4600
, “
TIME OUT
” will be indicated on the display. To resume transmitting,
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 operating function/feature change or inadvertent
transmission, various aspects of the front panel’s keys may be locked out.
To activate the Locking feature, press and hold in the
[
P1
]
key while turning the
radio on. To disable the Locking feature, repeat this power-on procedure.
