- Poor Range/Static: Move the base unit to a more central location, away from large metal objects, other electronic devices, or thick walls that may interfere with the signal.
- Answering System Not Recording: Check if the answering system is turned ON. Ensure there is sufficient recording time available.
- Smart Call Blocker Issues: Review your Smart Call Blocker settings in the handset menu to ensure it is configured as desired. Confirm that the numbers you wish to receive are added to your allowed list.
