The gyre is probably set to really slow frequency. The pulsing mode can be set as slow as 2 min off and 2 min on. The lights around the dial will blink at the same frequency starting with off first. If you are at the slow frequency, then when you are done setting up the speed and then move on to set the frequency, you will not see the lights blink at all. If you wait two minutes, you will then see the lights.
Instead of waiting the 2 minutes, just turn the dial counter clockwise a couple of times and you will see that the lights will start to blink a little more frequent. Once you see the lights blink, you will be able to set the correct frequency. Please know that the gyre will pulse each time you move the dial a click so when you are getting closer to your desired speed, go one click at a time.
Let me know if you have any issues still.
