RECEIVE AND TRANSMIT
■ Meter function
The transceiver has 4 transmit meter functions for
your convenience. Select the desired meter with the
[METER] switch.
•Analog transmit meter
➥ Push [METER] to select RF power (Po), SWR, ALC
or compression level (COMP).
In addition, the transceiver can display the multi-func-
tion digital meter in the LCD display, which displays
all transmit meters simultaneously.
•Multi-function digital meter
q Push [METER] for 1 sec. to turn the multi-function
digital meter ON or OFF.
w Push [(F-1)P-HOLD] to toggle the peak level hold
function ON or OFF.
•“P-HOLD” appears on the window title when the peak
level hold function is turned ON.

[METER] switch
■ SWR reading
The SWR meter indicates the SWR over the trans-
mission line in all modes.
q Push [TUNER] to turn the antenna tuner OFF.
w Push [METER] several times to select the Po
meter.
e Push [CW/RTTY] once or twice to select RTTY
mode.
r Push [TRANSMIT].
t Rotate [RF POWER] clockwise past the 12 o’clock
position for more than 30 W output power (30%).
y Push [METER] once to select the SWR meter as
the transmit meter.
u Read the SWR on the SWR meter.
The built-in antenna tuner matches the transmitter
to the antenna when the SWR is lower than 3:1.

INDICATION
Po
Indicates the relative RF output power in %.
SWR
Indicates the SWR over the transmission
line.
ALC
Indicates the ALC level. When the meter
movement shows the input signal level ex-
ceeds the allowable level, the ALC limits
the RF power. In such cases, reduce the
[MIC GAIN] control.
COMP
Indicates the compression level when the
speech compressor is in use.
