LG VX-4500

I just got this phone yesterday. I went to train commands, turned it on, and it said applying training, but I never did anything except turn it on. I must say it recognized my voice better after I turned it off, but I am wondering if it was supposed to give me words to say like the training numbers part did. I am suspicious about this phone, as that didn't work, and the little plastic protector wasn't on the front. I wonder if it was used before.
