Jack
A 1/4-inch, 3-contact jack accepts either monaural or
stereo headphones with 2- or 3-contact plugs. When a
plug is inserted, the loudspeaker is disabled.
N
OTE
:
When wearing headphones, we recommend that you
turn the AF Gain levels down to their lowest settings
before turning power on, to minimize the impact on
your hearing caused by audio “pops” during switch-
on.

[
MIC GAIN
] Knob
This knob adjusts the microphone input level for (non-
processed) SSB and AM transmission.
A
DVICE
:
Adjust the [
MIC GAIN
] knob while speaking in a some-
what louder than normal voice level, watch the ALC
level and adjust the [
MIC GAIN
] knob so that the ALC
level indication just reaches the right edge of the ALC
scale. Then, when you speak in your normal voice level,
you will not be over-driving the microphone amplifier
stages.
[
SPEED
] Knob
This knob adjusts the keying speed of the internal CW
keyer (4 ~ 60 WPM). Clockwise rotation increases the
sending speed.
When turning this knob while pressing the [
KEYER
]
button, the frequency display shows the keying speed.
Microphone Connector
This 8-pin jack accepts input from a microphone uti-
lizing a traditional YAESU HF transceiver pinout.
