Dear Darin:
Please phone one of my colleagues, Dr. Les Nagata for more information on
Racal suits. We have a couple at DRES, and I found them comfortable and easy
to use. Make sure that everything is plugged together, switched on and with
the breathing port seals removed (if you're not getting a good flow of air,
assume you haven't done something and get out of the hood to prevent
suffocation). The battery pack is a little bulky, but it's easy to get used
to. Take care..John
