Biodex provides easy-to-use manuals for all the products manufactured and distributed. The manuals are an excellent tool to maintain the integrity of your Biodex product or items purchased through us. As always, if there are questions you need answered not found in the manual or require more information, we encourage you to call a sales or technical representative at our Shirley, New York headquarters or the dealer you purchased the equipment from. Biodex is always available should you need us.
