■ Band voltage modification
If you want to connect an external unit which can be
controlled by the band voltage from [ACC] connec-
tor, the following modification is necessary. The band
voltage appears on pin 5 of [ACC] connector after
modification is completed.
Performing this modification is the customer’s re-
sponsibility. Icom does not guarantee this modifi-
cation’s result.
CAUTION: Disconnect the DC power cable
from the transceiver before any work on the trans-
ceiver.
• Band voltage generator circuit
The below circuit is just for reference.
The following band voltage table is for reference only.
Please adjust and confirm against the actual operat-
ing condition.
