Setup Guide

1. Charging the Headphones

Before first use, fully charge your Sentry BLWBT106 headphones. A full charge takes approximately 3 hours.

1. Connect the small end of the USB charging cable to the charging port on the headphone earcup.
2. Connect the larger end of the USB charging cable to a USB power adapter (not included) or a computer's USB port.
3. The LED indicator light will typically turn red while charging and turn off or change color (e.g., blue) when fully charged.

2. Bluetooth Pairing

Pair your headphones with your Bluetooth-enabled device (smartphone, tablet, computer) to enjoy wireless audio.

1. Ensure the headphones are fully charged.
2. Press and hold the Power button on the headphones for approximately 3-5 seconds until the LED indicator light begins to flash rapidly (often alternating blue and red), indicating pairing mode.
3. On your device, go to the Bluetooth settings menu.
4. Turn on Bluetooth and scan for available devices.
5. Select "BLWBT106" or "Sentry BLWBT106" from the list of found devices.
6. Once paired, the LED indicator on the headphones will typically stop flashing and may glow solid blue. A voice prompt may also confirm successful pairing.
7. If prompted for a password, enter "0000" (four zeros).

Note: The headphones will automatically attempt to reconnect to the last paired device when powered on, if that device's Bluetooth is active and within range.

You can also use the headphones with a 3.5mm audio cable for a wired connection, which is useful when the battery is low or for non-Bluetooth devices.
