INSTALLATION AND CONNECTIONS
Linear amplifier connections
CONNECTING THE IC-4KL
NOTE: Turn OFF the transceiver's antenna tuner while tuning the IC-4KL's tuner.
CONNECTING THE IC-2KL
CAUTION:
Set the transceiver output
power for 80 W max. with
the [RF POWER] control,
otherwise, a protection cir-
cuit will activate.
CONNECTING A NON-ICOM POWER AMPLIFIER
R WARNING:
Set the transceiver output power
and linear amplifier ALC output
level referring to the linear ampli-
fier instruction manual.
The ALC input level must be in the
range 0 V to –4 V, and the trans-
ceiver does not accept positive
voltage. Non-matched ALC and
RF power settings could cause a
fire or ruin the linear amplifier.
