It is the right equipment but, the batteries are not charging at all. I have left it on charge for more than 10 hours and as soon as we get it off the main it goes off. It is only working when connected to the power outlet. Hence any data saved and the settings are deleted once the power is disconnected. It therefore cannot serve the purpose for which we were bought for.I need urgent advise on what to do with it. Return it to the supplier?
