## Questions & Answers

**Q: How secure is the apple watch in the clip?  I'm doing ocean swimming**
A: It is surprisingly secure. Ive also come to use the headset with the watch bands on my wrist and not holstered in the clip so I can see stats and manipulate controls more easily

**Q: Why do I loose signal 1/2 way down the lap?**
A: You have likely paired your Interval with the phone and not the watch! If you are not using the watch - and want to use your phone - put the phone half way on the lane to improve the range. For more support - please email H2O Audio: support@h2oaudio.com

**Q: Does this connect Bluetooth to my Android phone? How well does it work for swimming laps?**
A: I'm pretty sure it connects to any bluetooth, I have an iphone.   The older model worked great, but the newer one I had to replace it with,  doesn't work more than 10 meters for me.  I swim laps in a 25m pool, so it's pretty useless.

**Q: The headphones work well but it’s not tracking my laps on the app,  what am I doing wrong?**
A: Hi Jill - please email us at support@h2oaudio.com and we can get you tips for improving the tracking. We are also about to release a new app version!
