## Questions & Answers

**Q: could I send the remote to the north pole and watch climate change and global warming with my brother?**
A: Santa.... is that you???

If you manage to figure out what's kind of wireless frequency this device runs on, you can then make a few thousand signal repeaters (much like a wifi repeater or mesh networking) leading from your living room to the north pole, ensuring to keep the repeaters less than 150' apart (as the advertised 200' is best case scenario, like an amplifier's RMS rating) for optional signal transmission. Yeah, it would totally work. I will have to warn you that latency will be a nightmare as this is a home product and your repeaters will be shoddily made. You'll most likely know what the conditions were in the North Pole 3 weeks ago. Stick to NOAA or The Weather Channel for more up to date conditions. (Totally not trolling)

**Q: is there a radio in this clock?**
A: THERE IS NO RADIO ON THIS CLOCK

**Q: Can 2 of these sc91 stations be connected to the same 3 wireless transmitters? i have 3 outside sensors and want to monitor them from 2 rooms.**
A: I believe you can if they are the same manufacturer and on the same channel. I have used one transmitter for two receivers in the past.

**Q: how do I set the time?  when daylight saving time started my clock did not adjust itself**
A: Please note that this clock is not atomic clock, the time needs to be set manually. To set the time, please long press SET button to enter the time setting.
