This quick-start guide provides essential information for immediate use, though a full user manual is recommended for comprehensive understanding.

Troubleshooting (Frequently Asked Questions):

Pairing Issues (Device not connecting):
- Ensure double-tap for pairing is quick (within 1.5 seconds).
- Verify "Bluetooth® pairing" announcement.
- Check phone's Bluetooth® settings: ensure scanning, toggle Bluetooth® off/on, restart phone.
- Manage paired devices: "forget" or "unpair" old Bluetooth® connections on your phone.
- Check for system updates on your phone.
- Perform a "factory reset" on the hearing protector.
- If issues persist, contact phone manufacturer for Bluetooth® firmware support.
Pairing to a Different Device: "Forget" or "unpair" the device from the previously connected phone before attempting to connect to a new device.
Automatic Shut-off: To turn the device back on after an automatic shut-off, press and hold the power button for 3 seconds.
White (Static or Wind) Noise: This can occur due to the external microphones picking up air movement (wind, HVAC) or other environmental pressures and frequencies, which are then played through the device. This is normal operation for the "hear through" feature. If you are not hearing your environment or music when microphones are on, contact customer service.

Maintenance Features:

Factory Reset: To reset the unit to default settings, turn the unit on, then press and hold the "Power/Bluetooth®" button and the "Volume" button simultaneously until the unit announces "Default Settings" and then turns off. This can resolve various software-related issues.

Warranty:

The manufacturer's warranty is one year with proof of purchase.
