The manual isn't that clear about relief recording. It saids that using a timer recording and there is not enough space on the RAM, it switches to the HDD. Does that mean when setting the timer for RAM and if there isn't enough room. the timer settings just switch to HDD and the whole recording gets put on the HDD. Or does it record onto the RAM and then swicth to the HDD when the RAM is full? I think it is the first one.
