BASIC OPERATION

Meter display

IC-PW2 has 6 different meters.
z Po:
Displays the relative RF output power.
: Displays the drain current of the final
z I
D
amplifier MOS-FETs.
z TEMP: Displays the temperature of the PA unit.
: Displays the drain voltage of the final
z V
D
amplifier MOS-FETs.
z SWR: Displays the SWR of the antenna at the
selected frequency band.
z ALC:
Displays the ALC level.
Touch the meter display to change the meter type.
→ I → TEMP → SWR → ALC
P V
O D D

D Displaying the Multi-function meter

You can simultaneously display all the parameters.
z Touch the meter display for 1 second to display the
Multi-function meter.
L To close the Multi-function meter, touch the meter
display for 1 second again.

D About the HOT zone of the TEMP meter

When the TEMP meter indicates the maximum value
of the HOT zone (TX Inhibit Protection zone), the
protection circuit is activated, and the linear amplifier
circuit is automatically turned OFF. (p. 8-1)
HOT zone (TX Inhibit Protection zone)
L Stop the transmission from the exciter, and DO NOT
transmit again until the meter is out of the HOT zone.

Confirmation before transmitting

Confirm the following before transmitting from the
exciter.
z The antenna is properly tuned.
z When the linear amplifier is used with 180 ~ 264 V
AC, it is set to the output power to be used (1 kW or
500 W).
z When an Icom CI-V exciter is connected, the
operation frequency and band are synchronized.
z For each output power (1 kW and 500 W), the
ALC level is adjusted for the RF input connectors
([INPUT 1] and [INPUT 2]).
z The following settings are properly set.
• The status of [INPUT 1] and [INPUT 2]
• The frequency band for [INPUT 1] and [INPUT 2]
• The linear amplifier circuit is turned ON or OFF
• The internal antenna tuner is turned ON or OFF
z Check the value of each meter after the last
transmission.
Caution for transmission:
DO NOT transmit from the exciter connected to
(Lights green: RX side). This could damage
the amplifier.
