[Icom] Frozen Send relay - 756

[Ken]

Hi Matt. Question, are you quoting the PROll manual from page 12 which
says, "Send control jack...16VDC/2A"; or the ACC(1)socket pin 3 from page
13 which says, "input current less than 200ma"? Could this be where the
confusion exists. I use the send control jack and have never had a problem
with the 756, 756PRO, or PROll. Ken
