slothbal1986 0 Posted February 5, 2012 I am having problem with my newly bought 2 avtech 798a dvrs and would need your expertise badly. Both of them came with only simplied chinese n traditional chinese under langauge. 1 of them currently is in english langauge (which i could refer from) but the is no english under the langauge option, the other is totally in chinese. Also, I have purchase 2 HDD, each 2TB but after i installed the HDD, it seems to be not reading it. Both DVR shows "No HDD" . Please help... Share this post Link to post Share on other sites
