Choosing the IR transmission channel Switching a channel off
By simultaneously pressing the buttons "CHANNEL" and "+" or "-" you start the search for the infra-red transmission channel which is to be assigned to the input. To switch a channel off, search through the transmission channels as described above. The OFF position is the next channel above "£ ¡" or below "ºº" (depending which way you go). The display will indicate "ºF." instead of a channel number and the corresponding LED will go off. NB: It is important that any unused channels are switched off. Any channel left on, but unused, will reduce the radiator coverage area accordingly. (See the section on calculating the radiator coverage area in the user manual supplied with the radiator). 12
