i 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
Decreases
o MIC GAIN CONTROL [MIC]
Adjusts microphone 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 swings within
the ALC range during normal voice level transmission in the
SSB or AM modes. (The ALC meter must be selected.)
Recommended level for
an Icom microphone

!0 VOX/BREAK-IN SWITCH [VOX/BK-IN]
➥ Push to turn the VOX function ON or OFF during
SSB, AM and FM mode operation. (p. 6-2)
➥ Push to turn the break-in function ON
break-in, full-break-in)
operation. (p. 6-3)
➥ Hold down for 1 second 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 48 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.
Short delay for
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 wide variety of the
transceiver's information and data.
• The indicator beside the slot lights or blinks when the
transceiver reads or writes to the memory card.
• Push the eject button to remove the memory card.
!5 MONITOR GAIN CONTROL [MONI GAIN] (p. 6-4)
Adjusts the transmit IF signal monitor level.
Push
!6 COMPRESSION LEVEL CONTROL [COMP]
(p. 6-5)
Adjusts the speech compression level in SSB.

!8 VOX GAIN CONTROL [VOX GAIN] (p. 6-2)
Adjusts the transmit/receive switching threshold
level for VOX operation.
