•
The “–” (negative offset) or “+” (positive offset) icon ap-
pears to represent the frequency offset direction.
•
“–” or “+” blinks when the Reversed Duplex function is ON.
For only USA version of IC-V80:
The Auto Repeater function has priority over the manual
duplex setting. If the transmit frequency changes after set-
ting, the Auto Repeater function may have changed the
duplex setting. Turn OFF the Auto Repeater function to
prevent this.
D

When the Reversed Duplex function is ON, the receive
and transmit frequencies are reversed.
