Here's a word to the  wise:  If you have an older premium receiver, check to 
see if it has a  nicad battery memory back up installed somewhere, and remove 
it.  Replace  it with one away from the circuit boards and in an area where it 
can be easily  replaced.  My next project will be to do that to my own 
RF-590.  I  checked and it has not yet started to leak, but will at some point I'm  
sure.

Hi John,
Very Good Advice!  I would also like to add that if someone decides to add a 
remote battery and  place it away from any circuit boards to please give a 
little thought as to how  they mount the battery. I have seen several receivers 
that were damaged because  someone used two-sided "sticky tape" to hold the 
battery on the chassis or else  just tucked the battery underneath some other 
wires or a ribbon cable  to  "hold it in place". In both cases the battery worked 
loose and smashed into  other circuit boards during shipping and caused 
extensive damage. A battery has  concentrated weight and can easily work loose if 
not properly secured to a  chassis if it is the size of 2 AA batteries or even 
2 AAA's in a plastic  holder.

It is easy to forget a battery is lying loose in a chassis  if the receiver 
is sitting on a shelf. But if the receiver is ever passed on to  another person 
or is shipped then real damage can happen!
