hi all , have a panasonic dmr hw220 freeview recorder , changed the remote control code the other day after switching machine off , remote control no longer functions for some reason , can switch the machine on via the on/off button located in top lef corner of machine , but when press remote nothing happens , i get set 5 in display , but i had changed it set 2 as not to switch on my other panasonic device , is there any way to do some kind of reset to let me somehow get the remote and unit working together , as said at the moment remote is not responding to machine , nothing in way of machine , and new batts in remote
