The blinking is normal while the MicroBeast initializes.
This is in the manual on page 71
"After powering up the MICROBEAST, it performs a brief initialization phase. A quick LED test turns all menu LEDs on simultaneously, and the Status-LED cycles through all colors. Then for about 3 seconds, the Status-LED turns red and the first two digits (X and Y) of the internal firmware version are displayed. Then, in the
remaining time a running light of the LEDs A - G signals that the sensors are being calibrated and the LEDs H - N do indicate the initialization of the receiver signals."
Hope this helps.
This hobby is WAY too expensive!!
