Sorry for the empty message previously sent (I hit the wrong key)
I just acquired a Teledyne-Geotech Portacorder (RV320B) drum recorcer from a 
friend.  Howver, I don't have a manual or connection instructions that shows 
how to hook it up.  The unit apparently operates on some type of battery but 
the battery is missing.  There is one long white wire and one long black wire 
with spade type connectors in the base of the unit which I assume should be 
connected to a battery.  Anyone having information on connecting this unit 
such as what type and voltage battery is used, should the above referenced 
wires be connected to the (-) terminal and (+) terminal of the battery 
respectively or any other information would be appreciated.  In addition, if 
anyone could provide a photocopy of a manual I would be glad to pay for it.
