Instead, the radio will generate short beep three
times. Release the PTT switch and wait for the
channel to be clear of activity.
 If the BTLO (Busy Tone Lockout) feature has
been programmed on an analog channel or
CCLO (Color Code Lockout) feature has been
programmed on a digital channel, the radio
opEratIon
can transmit only when there is no carrier be-
ing received or when the carrier being received
includes the correct tone (CTCSS tone or DCS
code) on an analog channel or correct code on a
digital channel.
Automatic Time-Out Timer
If the selected channel has been programmed for au-
tomatic 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 top panel’s red LED (“TX”
indicator) will disappear and transmission will cease
soon thereafter. To resume transmitting, you must re-
lease the PTT switch and wait for the “penalty timer”
to expire.
