1. Insert the iButton in the GuardDog’s socket. The iButton must touch the center contact
and at least one of the top contacts. (See Figure 5.)
The LED turns amber when the GuardDog is reading the button.
2. After the “chirp” and when the Fingerprint Sensor LED is blinking green, remove the
iButton from the socket and place your finger on the sensor.
The LED turns amber when the GuardDog is scanning your finger.
3. After the chirp and when the LED turns off, remove your finger.
The GuardDog emits three very quick chirps and both LEDs blink green to indicate that
you have been successfully verified.
If the GuardDog emits only a single chirp and the Fingerprint Sensor LED starts to blink
green again, the GuardDog was unable to verify you. Reposition your finger and repeat
step 3. If, after three tries, the GuardDog cannot make a verification, both LEDs blink red
and the unit emits three long beeps. See “Finger Selection and Placement Tips” on page 10
for more information about ensuring successful verification.
