of the Speaker/Microphone on the radio; secure
the connector pin using the screws supplied with
the Speaker/Microphone. Hold the speaker grille
up next to your ear while receiving. To transmit,
press the
PTT
switch on the Speaker/Microphone,
just as you would on the main transceiver’s body,
and speak into the microphone on a normal voice
level.
Note 1): Save the original plastic cap and its
mounting screws. They should be reinstalled
when not using the Speaker/Microphone.
2) When you press the PTT switch on the Speak-
er/Microphone, it disables the internal micro-
phone, and vice versa.

If the BCLO (Busy Channel Lockout) feature
has been programmed on an analog channel, the
radio will not transmit when a carrier is present.
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.
