Operation; I When First Applying Power (Cpu Resetting); I Setting The Alc Levels - Icom IC-PW1 Instruction Manual

I When first applying power
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.
q Make sure the linear amplifier, exciter and auxil-
iary power supply (p. 10) powers are OFF.
w While 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.
e Reset the exciter's CI-V settings after resetting.

I Setting the ALC levels

R CAUTION:
Final FETs may be damaged if
the ALC level adjustment is set incorrectly.
NOTE: Re-adjustment is necessary when replac-
ing the exciter.
q Select an antenna which has an SWR of 1.5:1 or
better.
w Set the 1st exciter's RF output power for the min-
imum output.
e Be sure that the [ALC adj1] and [ALC adj2] pots on
the rear panel max. counterclockwise. (default)
[ALC adj2] [ALC adj1]
r Push [POWER] to turn the linear amplifier power
ON.
t Push [UP] or [DOWN] to select an operating band
except 50 MHz band.
- Select a band which uses a well-matched 50 Ω anten-
na.
(CPU resetting)
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.

y Push the transmit meter-2 switch one or more
times to select the ALC level meter.
- The [ALC] indicator lights.
u Push [TUNER] to turn the antenna tuner ON.
- The [TUNER] light lights.
i While adjusting the 1st exciter's RF output power,
transmit a 100 W output power of the selected
band signal using CW or RTTY mode.
o Adjust the [ALC adj1] pot to the ALC adjustment
point as shown below.
