We just purchased the Rjtech 2200dvrx recorder, and it works great. The only problem we arehaving, is that when you set the time, it automatically goes back to default time after every recording and/or daily. No matter how many times we go in and set the time/time zone/date etc. the clock never stays on the correct time. Does anyone know why it does this? Is there a battery on board that may be dead...or something else we have to do to save the settings? Any help would be appreciated, because we really can't set the timer and record until we solve this problem.
