## Questions & Answers

**Q: Will the COROS Heart Rate Monitor support ANT+?**
A: No, There will be no ANT+ support as we are using a newer Bluetooth chip which does not provide ANT+ support but has far better computing power and lower power consumption than chips with ANT+ support.

**Q: Can I pair the COROS HR Monitor with My Phone?**
A: To record a workout with the COROS Heart Rate Monitor directly from your phone, we recommend using a free activity tracking app like Strava, MyFitnessPal, RunTracker, or others available on the iOS and Google Play stores.

**Q: Can I pair the COROS HR Monitor with My Phone?**
A: *The COROS app currently does not support recording activities on the app itself. The COROS HR Monitor can also pair with any fitness tracking watch, gym equipment, cycling computers, and more.**

**Q: Does the COROS Heart Rate Monitor work over tattoos?**
A: Depending on the density of the tattoo, the heart rate monitor may be able to get a reading but it's not guaranteed. If you have tattoos, we recommend adjusting the placement (bicep, forearm, opposite arm).

**Q: How do I charge the COROS Heart Rate Monitor?**
A: Connect the charging cable to the backside of the heart rate monitor. An orange light will appear while the monitor is charging. The light will turn green once it's fully charged.
