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 connec-
tor 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/Microphone,
just as you would on the main
transceiver’s body, and speak
into the microphone on a nor-
mal voice level.
Note 1): Save the original plastic cap and
its mounting screws. They should be rein-
stalled 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.
Do not remove/install the Speaker/Microphone
in a hazardous location.
r
If the Busy Channel Lockout feature has been pro-
grammed 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
“
Ý
CH Busy
Ý
” on the display (16-key and
4-key versions). Release the
PTT
switch and wait
for the channel to be clear of activity.
r
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.
