## Questions & Answers

**Q: How do I do the initial setup of the earbuds and connect them to a device?**
A: Once the earbuds are charged, remove from the charging cradle, enable Bluetooth on your device, and select “EAH-AZ40” for pairing. If prompted for a passkey, input “0000” (four zeros). Consult the Operating Instructions for more detail.

**Q: The earbuds are not fitting in my ears properly. How do I get a better fit?**
A: Choose an earpiece size that fits snugly, and twist gently as you insert in your ear for a secure seal. The Technics logo should read straight when they are inserted correctly.

**Q: Can I switch my connection from one Bluetooth Device to another?**
A: Yes! Once you pair your AZ40 earbuds to your devices via Bluetooth (see User Guide) you can connect to your devices through the device settings or through the Technics audio app.

**Q: How do I utilize Touch Controls?**
A: Consult your User Guide for a full key of Touch Controls, including play/pause, voice assistant, receive/reject call, and track forward/back.

**Q: Why does one earbud have better battery life than the other?**
A: The earbud that is removed from the case first starts the Bluetooth pairing process with your devices which may result in a slightly shorter battery life.
