Figure Display Array
Remote Control DEMO Guide
available display modes are: Mode Press corresponding emitter position will light shown Figure when switch emitter pressed. Mode Press with mirror position emitter array will light Mode Press Display CUSTOM CODE alternately 1sec rate with lower byte code underlined. this DEMO KIT, CUSTOM CODE 2C48H, will display first then (underlined), alternately every 1sec. Mode Press Display corresponding DATA CODE, lighted shown Figure
Note
mode selected, after first time valid code received, DEMO will display CUSTOM CODE continuously until display mode changed valid code received. Note that determine whether valid code received not, users only tell light flash DS66.
