We Care Details

Why isn’t my fingerprint being recognized?

Before adding fingerprints, please set a digital password first. Make sure your finger is clean and dry, as dirt, water, or worn fingerprints may affect recognition.

How many fingerprints can I register?

The Defender SE can store up to 50 fingerprints for authorized users.

What if the fingerprint or password does not unlock the device?

Use the physical backup key first. Then check whether the battery needs charging. If the issue continues, contact ONNAIS support at support@onnaisafe.com.

How long does the battery last?

The built-in battery lasts about 3–5 months in standby mode or approximately 2,000 unlocks. For best readiness, recharge every 2 months.

Can I turn off the sound?

Yes. Press and hold the Reset button for 3 seconds to mute operation sounds. Repeat the same step to turn sound back on.

What firearms does it fit?

The adaptive structure is designed to fit many handguns, rifles, and shotguns. Compatibility may vary by firearm model, trigger guard shape, and accessories.
