r If the BTLO (Busy Tone Lockout) feature 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 tone (CTCSS
tone or DCS code).
Automatic.Time-Out.Timer
If the selected channel has been programmed for auto-
matic time-out, you must limit the length of each trans-
mission. While transmitting, a beep will sound 10 seconds
before time-out. Another beep will sound just before the
deadline; the top panel’s red LED (“TX” indicator) will
disappear and transmission will cease soon thereafter. To
resume transmitting, you must release the PTT switch and
wait for the “penalty timer” to expire.
