R WARNING!
Set the transceiver output power and linear ampli-
fier ALC output level after referring to the linear
amplifier instruction manual.
The ALC input level must be in the range 0 V to
–4 V. The transceiver does not accept positive volt-
age. Non-matched ALC and RF power settings
could overheat or damage the linear amplifier.
The maximum signal level of [RELAY] jack is
16 V/0.5 A DC with initial setting, and 250 V/200 mA
with "MOSFET" setting (see p. 12-8 for details). Use
an external relay unit if your non-Icom linear ampli-
fier requires control voltage and/or current greater
than specified.
