1 PANEL DESCRIPTION q POWER SWITCH [POWER] (p. 11) Push momentarily to turn power ON. w TRANSMIT INDICATOR [TRANSMIT] (p. 13) Lights green while transmitting. During transmission, a humming may sound depending on the output power. This is caused by the large current produced by the power supply and does not indicate equipment malfunction. e ANTENNA 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). r ANTENNA 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. t LINEAR 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 protector 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. y LOWER BAND SELECTOR [DOWN] (p. 13) Selects the lower operating band when pushed. u AUTOMATIC INDICATOR [AUTO] (p. 13) Indicates that automatic band selection is activated. (When an Icom CI-V transceiver is connected.) i BAND INDICATORS (p. 13) Indicate the selected operating band. o UPPER 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 (VD), SWR (Standing Wave Ratio) or ALC (Automatic Level Control) level. !3 TRANSMIT METER-2 SELECTOR Selects the final FET's voltage (VD), SWR (Standing Wave Ratio) or ALC (Automatic Level Control) level for transmit meter-2. !4 TRANSMIT METER-1 [METER-1] Shows the RF output power (PO), final FET's current (ID) or heatsink temperature (TEMP). !5 TRANSMIT METER-1 SELECTOR Selects the RF output power (PO), final FET's current (ID) or heatsink temperature (TEMP) for transmit meter-1. 2
