PANEL DESCRIPTION
qPOWER SWITCH [POWER](p. 11)
Push momentarily to turn power ON.
wTRANSMIT INDICATOR [TRANSMIT](p. 13)
Lights green while transmitting.
During transmission, a humming may sound de-
pending on the output power. This is caused by
the large current produced by the power supply
and does not indicate equipment malfunction.
eANTENNA TUNER INDICATOR [TUNER](p. 13)
•Lights while the antenna tuner is activated.
•Blinks while tuning and the SWR becomes 1.5:1 or
greater on the 50 MHz band.
•Goes out after slow blinking when antenna turner
cannot tune the selected antenna (SWR 1.5:1 or
greater).
rANTENNA TUNER SWITCH [TUNER](p. 14)
•Turns the antenna tuner ON and OFF (bypass)
when pushed momentarily.
- The [TUNER] indicator lights while the antenna tuner is
activated; blinks while tuning.
- While operating in the 50 MHz band, the antenna tuner
does not start automatically. Push [TUNER] for 2 sec.
to tune the antenna manually.
•Starts to tune the antenna manually when pushed
for 2 sec.
- When the tuner cannot tune the antenna (SWR 1.5:1
or greater), the tuning circuit is bypassed automatically
after 20 sec.
tLINEAR AMPLIFIER SWITCH [AMP/PROTECT]
Turns the linear amplifier ON and OFF.
- The [AMP/PROTECT] indicator lights green when the
linear amplifier is ON. (p. 13)
- The [AMP/PROTECT] indicator lights red when the pro-
tector circuit is activated. (p. 14)
- When the linear amplifier is OFF, the [AMP/PROTECT]
does not light and the exciter’s signal is applied to one of
the output connectors or the IC-PW1’s antenna tuner.
yLOWER BAND SELECTOR [DOWN](p. 13)
Selects the lower operating band when pushed.
uAUTOMATIC INDICA TOR [A UT O](p. 13)
Indicates that automatic band selection is activated.
(When an Icom CI-V transceiver is connected.)
iBAND INDICATORS(p. 13)
Indicate the selected operating band.
oUPPER BAND SELECTOR [UP](p. 13)
Selects the higher operating band when pushed.
!0 OUTPUT ANTENNA SELECTOR [ANT](p. 13)
Selects one of 4 output antenna connectors.
!1 INPUT ANTENNA SELECTOR [INPUT](p. 13)
Selects one of 2 input antenna connectors.
!2 TRANSMIT METER-2 [METER-2]
Shows the final FET’s voltage (V
D
), SWR (Standing
Wave Ratio) or ALC (Automatic Level Control) level.
!3 TRANSMIT METER-2 SELECTOR
Selects the final FET’s voltage (V
D
), SWR (Stand-
ing Wave Ratio) or ALC (Automatic Level Control)
level for transmit meter-2.
!4 TRANSMIT METER-1 [METER-1]
Shows the RF output power (P
O
), final FET’s cur-
rent (I
D
) or heatsink temperature (TEMP).
!5 TRANSMIT METER-1 SELECTOR
Selects the RF output power (P
O
), final FET’s cur-
rent (I
D
) or heatsink temperature (TEMP) for trans-
mit meter-1.
