I feel bad that your question has gone unanswered, but I honestly do not know.
I would read the owners manual under set up procedures. If there is danger they should address that topic in the text. Another option would be to look up the manufacturer on the web and email their tech department directly. If you are in a hurry, there is always the phone.
Hope this works out for you and your Father in-Law.
