Nice opener beeps or flashes a specific pattern but shows no alphanumeric error code; operation is limited.

Safety first: Observe the door during operation to ensure it is safe before continuing to use it.

• Consult manual for pattern: Count the number of flashes or beeps and refer to the Nice manual for the meaning of that pattern.
• Perform maintenance: Lubricate moving parts, check balance, and inspect safety devices. Some Nice units allow resetting the maintenance counter via the programming menu.
• Check accessories: Replace batteries in wireless accessories if the pattern indicates low battery.
• Reset indication: Use the prescribed button sequence to clear the service reminder after maintenance is completed.
