If a Speaker/Micro-
phone is available,
remove the plastic cap
and its two mounting
screws from the right
side of the transceiver,
then align the con-
nector of the Speaker/
Microphone on the transceiver body; 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/Micro-
phone, just as you would on the main trans-
ceiver’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
Speaker/Microphone, it disables the internal
microphone, and vice versa.

If the BCLO (Busy Channel Lockout) feature
has been programmed on the channel, the radio
will not transmit when a carrier is present. In-
stead, the radio will generate short beep three
times. Release the
PTT switch and wait for the
channel to be clear of activity.
r
If the BTLO (Busy Tone Lockout) feature has
been programmed on the channel, the radio
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 the channel.
