i MIC GAIN CONTROL [MIC]
Adjusts microphone input gain.
• The transmit audio tone in SSB, AM and FM modes can
be adjusted independently in set mode. (p. 12-4)
✔ How to set the microphone gain.
Set the [MIC] control so that the ALC meter sometimes
swings during normal voice transmission in SSB, AM or FM
mode.

an Icom microphone

o RF POWER CONTROL [RF PWR] (p. 3-12)
Continuously varies the RF output power from min-
imum to maximum
(5 W*)
*AM mode: 5 W to 50 W

!0 VOX/BREAK-IN SWITCH [VOX/BK-IN]
➥ Push to turn the VOX function ON and OFF dur-
ing SSB, AM and FM mode operation. (p. 6-2)
➥ Push to turn the break-in function ON
and OFF during CW mode opera-
in, full break-in)
tion. (p. 6-3)
➥ Push for 1 sec. to enter VOX set mode. (p. 6-2)
✔ What is the VOX function?
The VOX function (voice operated transmission) starts trans-
mission without pushing the transmit switch or PTT switch
when you speak into the microphone; then, automatically re-
turns to receive when you stop speaking.
✔ What is the break-in function?
The break-in function switches transmit and receive with CW
keying. Full break-in (QSK) can monitor the receive signal
during keying.
!1 ELECTRONIC CW KEYER SPEED CONTROL
[KEY SPEED] (p. 4-4)
Adjusts the internal electronic CW keyer's speed.
• 6 wpm (min.) to 60 wpm (max.) can be set.

!2 BREAK-IN DELAY CONTROL [DELAY] (p. 6-3)
Adjusts the transmit-to-receive switching delay time
for CW semi break-in operations.

high speed keying
!3 MONITOR SWITCH [MONI] (p. 6-4)
Monitors your transmitted IF signal.
• The CW sidetone functions regardless of [MONI] switch
setting in CW mode.
• The [MONI] indicator above this switch lights green
while the function is activated.
!4 MEMORY CARD SLOT [CF CARD] (p. 2-3)
Insert the supplied CF (Compact Flash) memory
card for both reading/storing a variety of trans-
ceiver's information or data.
• The indicator beside the slot lights or blinks when the
transceiver accessing to the memory card for reading or
writing data.
• Push-in the eject button to remove the memory card.
!5 MONITOR GAIN CONTROL [MONI GAIN] (p. 6-4)
