If a Speaker/Microphone

is available, remove the
plastic cap and its two
mounting screws from
the right side of the
transceiver, then align
the connector 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
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.
