Troubleshooting - Chamberlain 942FP Manual

Erase/Reset
• To erase users:
NOTE: Erasing a user will erase ALL stored fingerprints. User
does NOT need to reprogram to opener.
1. Open cover and wait until Ready
LED is lit.
2. Enrolled user must slowly and firmly
swipe fingerprint.
3. Press and hold the Enroll button for at
least 6 seconds. The Pass LED and Fail
LED will flash for 15 seconds. During
this time the Resend button is active.
After 15 seconds the Enroll and Ready
LEDs will light indicating fingerprints are
erased. The unit will return to Enroll
mode.
• To return unit to Factory Reset state:
NOTE: Factory reset state will erase ALL stored fingerprints.
This method should be used ONLY when an enrolled user is
not available as it requires user to reprogram unit to opener.
1. Open cover and wait until Ready
LED is lit.
2. Press and hold the Enroll button
until all LEDs turn off. Release
button.
3. Again press and hold the Enroll
button until the Ready and Enroll
LEDs are lit and not flashing.

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 (signalled 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.
