D Connecting a non-Icom linear amplifier

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. The transceiver does not accept positive volt-
age. Non-matched ALC and RF power settings
could cause a fire or damage the linear amplifier.
The maximum control level of [RELAY] jack
is 16 V/0.5 A DC with the initial setting, and
250 V/200 mA with the "MOS-FET" setting
20-4 for details). Use an external relay unit when
your non-Icom linear amplifier requires a control
voltage and/or current greater than specified.
When using a linear amplifier that has a time delay
between receiving and transmitting, a high SWR
might cause the linear amplifier to malfunction. To
prevent this, slow the TX Delay the "TX Delay (HF),
(50M)" settings in the Others Set mode.
