OPERATION

■Setting the ALC levels

Before ﬁrst applying power, make sure all connec-

tions required for your system are complete by refer-

ring to chapter 2. Then, reset the linear ampliﬁer

using the following procedure.

NOTE: Resetting CLEARS all programmed set-

tings to default values.

qMake sure the linear ampliﬁer, exciter and auxil-

iary power supply (p. 10) powers are OFF.

wWhile pushing [UP] and [DOWN], push [POWER]

to turn power ON.

- The internal CPU is reset.

- The remote controller shows its initial condition when

resetting is complete.

eReset the exciter’s CI-V settings after resetting.

(pgs. 13, 14)

If the controller’s power is supplied from non-Icom

exciters or auxiliary power supply (p. 10), turn the

exciter or auxiliary power supply ON while pushing

[UP] and [DOWN] to reset the CPU.

RCAUTION: Final FETs may be damaged if

the ALC level adjustment is set incorrectly.

NOTE: Re-adjustment is necessary when replac-

ing the exciter.

qSelect an antenna which has an SWR of 1.5:1 or

better.

wSet the 1st exciter’s RF output power for the min-

imum output.

eBe sure that the [ALC adj1] and [ALC adj2] pots on

the rear panel max. counterclockwise. (default)

rPush [POWER] to turn the linear ampliﬁer power

ON.

tPush [UP] or [DOWN] to select an operating band

except 50 MHz band.

- Select a band which uses a well-matched 50 Ωanten-

na.

yPush the transmit meter-2 switch one or more

times to select the ALC level meter.

- The [ALC] indicator lights.

uPush [TUNER] to turn the antenna tuner ON.

- The [TUNER] light lights.

iWhile adjusting the 1st exciter’s RF output power,

transmit a 100 W output power of the selected

band signal using CW or RTTY mode.

oAdjust the [ALC adj1] pot to the ALC adjustment

point as shown below.

!0 Check that the Po meter shows 1 kW output

power.

!1 Adjust the [ALC adj2] pot in the same manner

when a 2nd exciter is connected.
