Your customer service people are not much. They didnt even know where to tell me where the model number was. Just keep asking for me to look for the sticker on the unit outside. I finally found it myself under the battery. The problem I discovered myself its the battery after calling back and going over everything again. I ask about getting a new battery through warranty NO was the answer I offered to buy one NO you cant buy one. But I could buy a new unit why do that oh so I would have a warranty Thats when I hung up. I still havent purchased a battery yet. I sure hope this helps you improve your customer service. Your product works great when you can use it. Bob Hardy User's recommendation: Don’t call customer service!!
