i have a dish remote used for the 301.it says 3.0 IR on the back 119946. it doesn't work but the red lights come on when i push sat,tv,ect.i changed batteries and still nothing.it has a little green button with a R on it.i thought maybe it meant reset so i held it in for about 5 seconds,the buttons at the top flash but that's about it.is there something else i can try?
