Most manufacturers are now providing e-mail addresses on their Web pages. If they do provide an e-mail address, give it a try. Chances are you will probably have a better chance of getting your question answered via e-mail than getting connected via the telephone. Some Web pages may also reference UseNet News Groups that discuss the use of certain products or products types. If you have access to a news reader, this is another good source of information.
Some manufacturers keep lists of known bugs and solutions on their Web pages.
Some of these lists are even searchable, making it very fast and simple to look up the answer to your problem. Assuming you have searched the known bugs listed on the manufacturers Web pages, you may have discovered an unknown bug. Some manufacturers allow you to submit detailed bug reports via their pages. It is possible that you may have discovered a new problem the manufacturer wasn't aware of. Usually the manufacturer will get back to you via e-mail and suggest a fix for the problem.
