Overview

For use with any 315 MHz SECURITY✚

garage door openers

having a purple “learn” button (refer to Step 4).

The system uses biometric technology that enables an

authorized user to gain access by scanning their fingerprint.

The sensor strip on the unit makes a numeric template of the

fingerprint that is unique to that user. The unit’s memory can

store up to four fingerprints.

• The term “enroll” refers to scanning the fingerprint so the

device will recognize the user.

• The term “swipe” refers to the movement of the finger across

the sensor strip.

• The term “LED” stands for Light Emitting Diode. There are

6 LEDs located on the Fingerprint Keyless Entry.

When unit is on, it is programmed to shut off after a short

period of time. The unit’s sensor strip is sensitive so it is

important to read the Tips for Success before attempting to

use the Fingerprint Keyless Entry.

NOTE: Do not attempt swiping your finger across sensor strip

until you are ready to enroll as you may inadvertently begin the

enroll process.

1. Remove cover.

2. Fasten bottom screw to mounting surface. Allow 1/8"
