I didn't realise a manual for an early plasma TV such as the one we were gifted could be so easily obtained. No manual was supplied with it, and as senior citizens we were a little puzzled over some aspects of its use. I do not want a listing for your store credit as we are not fairly big computer users. The manual was well organised, as it should be, with its backing of the Pioneer name. The download was prompt and everything worked quite smoothly. Thank you. Gordon.
