Troubleshooting

• If no known enrolled users are available:

— The memory must be erased using the Factory Reset

process.

• If the unit does not recognize a swiped fingerprint:

— Ensure that the Ready LED is lit before you swipe.

— Ensure that fingerprint is swiped correctly (See Tips for

Success).

— Ensure that fingerprint is enrolled.

— Ensure that sufficient pressure is being applied to sensor

strip (do not press too hard).

— Ensure that the sensor and finger are not wet.

• If the unit is in Enroll mode at power up:

— Complete enrollment process for initial user.

— The initial enroll process failed (signaled by a lit Enroll LED

and Fail LED) and must be repeated.

• If enrolling new user and all LEDs flash and unit returns

to Ready mode:

— The memory is full. In order to add new user, the memory

needs to be erased. Refer to Erase User or Factory Reset.

• If the unit does not wake:

— A button may be stuck. Press Enroll and Resend buttons

to ensure free movement.

— The batteries may need to be replaced.

• If the Fail LED flashes during use:

— The batteries need to be replaced.

NOTE: If sensor is dirty, user should wipe sensor with a clean

finger. It is recommended that the sensor be periodically

cleaned with a lint-free cloth dampened with alcohol.
