[Icom] Frozen Send relay - 756

Mon, 27 May 2002 16:50:19 -0700

On page 19 of my manual 'Connecting a non-ICOM linear amplifier' states, ' 
...  the SEND relay are 16V DC 2 A.  ... '
I used my short-shighted eyes without glasses to read.   This is why my 
arithmetic teacher said, 'Always write a decimal fraction with a zero 
unit.  Otherwise, it is not a number and can be confused.'  That is .2 is 
not a number!   0.2 is a number.
