### Frequently Asked Questions
#### How do I verify anti-freeze tech is active before UFC 311 prelims?
After setup, open **Smart IPTV Player** > **Help** > **System Check**. A green “Buffer Protection: Active” message confirms the feature is live. Run this 10 minutes before first bell.
#### Does the free trial work for UFC 311 prelims?
Yes—free trial grants full access to prelims and main card. It expires at 11:59 PM UTC on fight day. No credit card required.
#### Can I use this on a Firestick 4K?
Absolutely. All tested Firestick models—including 4K Max—receive the same anti-freeze optimization. Use an HDMI 2.0 cable for 1080p+ streams.
#### What if the stream buffers during the octagon walk?
That’s covered by our guarantee. Tap Live Support immediately—we refund or reissue access if freeze exceeds 20 seconds during fighter intros or walkouts.
