Setup

1. Initial Charging:

   Before first use, place both earbuds into the charging case. Connect the charging cable to the case and a power source. The LED display on the case will indicate the charging status. Fully charge the earbuds and case for optimal performance.

2. Powering On:

   The earbuds will automatically power on when removed from the charging case. If they do not, press and hold the touch control area on each earbud for 3 seconds.

3. Bluetooth Pairing:
   • Ensure Bluetooth is enabled on your device (smartphone, tablet, etc.).
   • Open the charging case and remove the earbuds. They will automatically enter pairing mode (indicated by a flashing LED on one or both earbuds).
   • On your device, search for Bluetooth devices and select "SENTRY Earbuds" (or similar name).
   • Once connected, the LED indicator on the earbuds will stop flashing and remain solid or turn off, depending on the model.

Operating Instructions

Touch Controls:

The SENTRY Ultra-Light Bluetooth Earbuds feature intuitive touch controls on each earbud. The functions may vary slightly between left and right earbuds.

Charging the Case:

When the charging case battery is low, connect it to a USB power source using the provided charging cable. The LED indicators on the case will show the charging progress.

Maintenance

• Cleaning: Use a soft, dry cloth to clean the earbuds and charging case. Do not use abrasive cleaners or solvents.
• Storage: Store the earbuds in their charging case when not in use to protect them and keep them charged.
• Avoid Water: While designed for workouts, avoid submerging the earbuds in water. Wipe off sweat after use.
• Temperature: Do not expose the earbuds to extreme temperatures (hot or cold) or high humidity.

Troubleshooting

• Earbuds not pairing with device:

  Ensure earbuds are charged. Turn off and on Bluetooth on your device. Forget the device in your Bluetooth settings and try pairing again. Ensure earbuds are in pairing mode (LED flashing).

• Only one earbud working:

  Place both earbuds back into the charging case, close the lid, wait a few seconds, then open and remove them. This often re-syncs them. Check battery levels for both earbuds.

• Low volume or poor sound quality:

  Adjust volume on both your device and the earbuds. Clean any debris from the earbud speakers. Ensure earbuds are properly seated in your ears.

• Charging case not charging:

  Check the charging cable and power adapter. Ensure the cable is securely connected to both the case and the power source. Try a different cable or power source.
