Adjusting the microphone gain
Adjust the microphone gain as described below.
1. Set the operating mode to SSB, AM or FM.
(p. 3-3)
2.
Push
MULTI
to display the Multi-function menu.
3.
Touch “MIC GAIN.”

Meter display
D
Meter display selection
You can display one of the 6 different transmit
parameters (Po, SWR, ALC, COMP, VD and ID) for
your convenience.
Touch the parameter to display one of the meters.
D
Multi-function meter
You can display all the parameters simultaneously.
L
The power amplifier temperature (TEMP) meter is also
displayed on the Multi-function meter.
Hold down the parameter for 1 second to display the
Multi-function meter.

The TX/RX indicator lights red and
is displayed.
5.
Rotate

Returns to receive
S:
Displays the receiving signal strength level.
Po:
Displays the relative RF output power.
SWR:
Displays the SWR of the antenna at the
operating frequency.
ALC
:
Displays the ALC level. When the meter
movement shows the input signal level exceeds
the allowed level, the ALC limits the RF power.
In such cases, decrease the microphone gain
level.
COMP:
Displays the compression level when the
speech compressor is used.
VD:
Displays the drain voltage of the final amplifier
MOS-FETs.
ID:
Displays the drain current of the final amplifier
MOS-FETs.
TEMP:
Displays the temperature of the final amplifier
MOS-FETs.
Information
L
•
In the SSB mode, touch the TX meter to select
the ALC meter and adjust until the meter reading
swings between 30 to 50% of the ALC scale.
•
Hold the microphone 5 to 10 cm (2 to 4 inches)
from your mouth, then speak at your normal voice
level.
•
In the AM or FM mode, check the audio clarity with
another station, or use the Monitor function (p. 4-11).
Lights red
Displays the drain
voltage of the final
amplifier MOS-FETs.
Displays the temperature
of the final amplifier
MOS-FETs.
