Acer Iconia B1-711

Hi

I just bought the latest tablet whilst over in Doha, and of course it didn't come with a User Guide? and unlike my previous Acer Iconia B1-71 there is no guide on the tablet. I went to Acer's and Qatar Acer's web site to try and download the User Guide, the only document available is App. Guide which is a kernal zip file whatever that is? I downloaded and then tried to unzip it using WINRar but it asked me for a password? I went on chat to customer service and they just keep insisting it is not password protected?

Has anyone got this new tablet version and has anyone managed to get a User Guide? If so can you explain how I can get one or can anyone give me a link so I can download the file or download a zip file that isn't password protected?
