[ICOM] Oh NO!!!!

[Ken Sands]

Great!
I just got a used 756Pro-2 and PS-125, and now it's gonna die from ESD??
What is the wisdom here, leave it unplugged from all antennas, ground and
power and keep it buried in a plastic ESD box in the basement away from
anything remotely electronic, or carpeting or....?????  Help!!!
