ing screws. They should be reinstalled when
not using the Speaker/Microphone.
Note: When you press the PTT switch on the
Speaker/Microphone, it disables the internal mi-
crophone, and vice versa.
If the Busy Channel Lockout feature has been
programmed on a channel, the radio will not trans-
mit when a carrier is present. Instead, the radio
will generate short beep three times and indicate
“
CH Busy
” on the display (16-key and 4-
key versions). Release the
PTT
switch and wait
for the channel to be clear of activity.
If CTCSS or Digital Coded Squelch (DCS) Lock-
out has been programmed on a channel, the radio
can transmit only when there is no carrier being
received or when the carrier being received in-
cludes the correct CTCSS tone or DCS code.
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 “
TX
” indicator will dis-
appear and transmission will cease soon thereafter.
To resume transmitting, you must release the
PTT
switch and wait for the “penalty timer” to expire.
