R WARNING:
Set the transceiver output power and linear ampli-
fier ALC output level referring to the linear amplifier
instruction manual.
The ALC input level must be in the range 0 V to
–4 V, and the transceiver does not accept positive
voltage. Non-matched ALC and RF power settings
could cause a fire or ruin the linear amplifier.
The maximum control level of [RELAY] jack is DC
16 V/0.5 A with initial setting, and 250 V/200 mA with
"MOS-FET" setting (see p. 12-9 for details). Use an
external relay unit when your non-Icom linear ampli-
fier require the control level that higher voltage
and/or larger current capacity.
