Applications
FAQ
What fingerprint sensor does the ETV-R1 use?
A semiconductor sensor, which reads the live surface of the finger instead of an optical image, so dry skin and fingerprints left on the sensor have less effect on recognition.
Which doors does the ETV-R1 fit?
Doors from 40 mm to 120 mm thick, including wooden doors, copper doors and security doors.
What happens when the batteries run flat?
The lock runs on four AA batteries with a low-battery alarm. If they are fully depleted, use the Type-C emergency port with a power bank, or open the door with the mechanical key.
