PANEL CARE
The digital GSM panel facia is brushed stainless steel. It is important that the facia is cleaned on regular occasions to prevent dirt
build up and tarnishing of the metal. A general household metal polish can be used but care should be taken to follow the grain
of the metal when polishing and also avoid any polish build up around the panel buttons which may prevent the buttons from
operating correctly.
