Sentry support FAQ

សំណួរទូទៅអំពីសៀវភៅដៃ ការចុះឈ្មោះ និងការគាំទ្រសម្រាប់ម៉ាកនេះ។

  • How do I pair my Sentry Bluetooth headphones?

    Turn off the Bluetooth function on your device. Power on the headphones/earbuds (usually by long-pressing the power button) until the LED flashes red and blue, indicating pairing mode. Open Bluetooth settings on your device, search for the model number (e.g., BT969, BTO300), and select it to connect.

  • What should I do if only one Sentry earbud is working?

    This often occurs if the earbuds are not synced. Place both earbuds back in the charging case. Ensure they are charging. Remove them simultaneously; they should auto-pair with each other within a few seconds. If not, try resetting them by long-pressing the buttons on both earbuds while they are powered off, then re-pair.

  • How do I claim the warranty for my Sentry product?

    Sentry Industries offers a limited 90-day warranty. Defective products can be returned to Sentry directly at PO Box 885, One Bridge Street, Hillburn, NY 10931. A check for return shipping (typically $5) is usually required. Check your specific user manual for precise details.

  • How do I charge my Sentry wireless earbuds?

    Place the earbuds into the charging case. Ensure the case itself is charged via the included USB-C cable. LED indicators on the case or earbuds will light up (often red or blue) to indicate charging status and turn off when fully charged.
