I began looking online. We once had to buy a new remote for the lounge room pvr and it was about $60. I found one for R's machine on eBay for $58, plus postage. Too much. I then discovered that Australian Topporo, importer of the Topfield units, went into receivership although its Korean parent company is alive and well.
I came across a couple of sites selling the appropriate remote control, the control having been superseded by a new model. One was in Ireland which wanted $27 plus postage and one in China, selling them for $20 plus postage, the total cost $29. We decided to take a chance and ordered the one from China. I then forgot I could track the delivery progress and after it not arriving for two weeks, I thought we might have lost the $29. Not much you can do when the company is in China.
I decided at the weekend that I would follow it up on Monday, but that day the unit turned up. It turned the pvr on and works fine, just as it should. But there is one problem and both R and myself cannot work it out.
We can't make the unit stop playing a recording without turning the unit off, and nor can we make it instantly record. The button to stop play and to instantly record are in a second column on the chart below with the heading shift. I think that must mean there is something like a keyboard shift key, but it is not on this list and we simply can't work it out. Google is not being helpful either. The alternative to switching it off and on again is keeping the old remote control too and use that for those two functions. I don't mind not knowing what I don't need to know, but I do mind not being able to work out something that is operationally important.
Later edit: It is always helpful to read your own posts. I just clicked on the photo of the remote to make sure it is a clear photo, and there at the top left, in blue is the 'Shift' button. Any brighter and it would have slapped me in the face. R is napping so I can't check but I bet by pushing that and then the stop button, the playing recording will stop.
