R WARNING!
• The maximum signal level of the [SEND] jack is 16 V/0.5 A DC with the "Reed" setting, and 250 V/200 mA with the
"MOSFET" setting. Use an external unit if your non-Icom linear amplifier requires a control voltage and/or current greater
than specified.

• The ALC input level must be in the range 0 to –4 V. The transceiver does not accept a positive voltage. Non-matched ALC
and RF power settings could overheat or damage the linear amplifier.
• 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, set "TX Delay."

Connecting a Transverter

When you use a non-Icom transverter unit, connect it as described below.
L Confirm that the transceiver and transverter are OFF before connecting them.
L You may need to connect to [ALC], depending on the transverter.
