WARNING!
• Set the transceiver output power and linear amplifier ALC output level after referring to the linear amplifier in
-
struction manual.
• The ALC input level must be in the range 0 V to –3 V.The transceiver does not accept a positive voltage. Non-
matched ALC and RF power settings could overheat or damage the linear amplifier.
• The IC-9100 SEND terminal (ACC connector pin 3) is rated at 16 V/0.5 A DC. If this value is exceeded, a larger
external relay must be used.
