Radio Trouble

We are having trouble with our radio. The radios are not communicating with eachother. The robot controler has a ORANGE BLINKING light on the RC Mode, it was not yellow, what is orange blinking? Also the OpInt Data light is red, but it says there is a radio, also the bot says the radio is working to, they just can’t see each other. They worked earlier in the year. We alrady reloded the defalt script but no luck. Any ideas?

did you folks tether up the robot first?

yea, teather worked fine, but still, radio is dead…

we had that before but the radios were not old so we change them into a new ones and now every thing is fine
