4. Operating Instructions

4.1. Blocking Unwanted Calls

The Enf510 offers multiple ways to block unwanted calls:

• Manual Blocking (During a Call): If you receive an unwanted call, simply press the large red BLOCK button on the Enf510 unit. The call will be immediately disconnected, and the number will be added to your block list.
• Manual Blocking (Using Phone Keypad): If you are not near the Enf510 unit during an unwanted call, you can press "#" then "6" on your telephone keypad. This will also immediately cut off the call and add the number to the block list.
• Blocking from Call List: After a call, you can browse the "CALL LIST" on the Enf510. If you find an unwanted number, select it and press the BLOCK button to add it to the block list.

4.2. Family List

The "FAMILY LIST" feature allows you to whitelist important numbers, ensuring they are never blocked, even if they match a pattern in the block database. This prevents accidental blocking of friends or family.

• To add a number to the Family List, use the FAMILY LIST buttons (up/down arrows) to navigate and select the number, then confirm.
• Numbers in the Family List can call you at any time and cannot be blocked by any method.
• The Enf510 supports a Family List capacity of up to 16 numbers.

4.3. Call List

The "CALL LIST" records the last 20 incoming calls, including those that were blocked. This allows you to review recent calls and manually add unwanted numbers to the block list if they were not blocked automatically.

• To view the Call List, press the CALL LIST button.
• Use the up/down arrow buttons to scroll through the recorded numbers.
• New calls will overwrite the oldest entries once the list is full.

4.4. Deleting Numbers

To remove a number from the Block List or Family List:

• Navigate to the desired list (Block List or Family List).
• Use the up/down arrow buttons to select the number you wish to delete.
• Press the DELETE button (trash can icon) to remove the number.

5. Advanced Blocking Features

The Enf510 comes with robust features to combat various types of unwanted calls:

• Preloaded Block List: The device is preloaded with over 4000 frequently complained caller numbers, offering immediate protection against known spam and scam calls.
• Manual Block Capacity: You can manually add up to 3000 numbers to your personal block list.
• Blocking by Area Code/Prefix: The Enf510 allows you to block entire area codes or numbers that start with specific fixed digits (e.g., 00, 443, 800, 855, 999).
• Blocking Specific Call Types: You can configure the device to block International, Private/WITHHELD, VOIP/Out of Area, and Unavailable numbers. These settings are typically "On" by default for International, VOIP/Out of Area, and Private numbers, while "Unavailable numbers" is "Off" by default.

7. Troubleshooting

If you encounter issues with your Enfizi Enf510 Call Blocker, please refer to the following common solutions:

• Device Not Powering On: Ensure the telephone line cable is securely connected to the "TEL LINE" port on the Enf510 and that your telephone line is active. The device draws power directly from the line.
• Calls Not Being Blocked:
  • Verify that Caller ID service is active on your phone line. The Enf510 relies on Caller ID information.
  • Check if the number is on your "FAMILY LIST". Numbers on this list will not be blocked.
  • Ensure the number is correctly added to your block list.
  • Some new variant numbers may bypass the preloaded database. Manually block these numbers using the BLOCK button or by pressing "#6" on your phone.
• Display Not Showing Caller Name: The Enf510 is designed to display only the caller's number, not their name. This is normal operation.
• Intermittent Issues: Ensure all cables are securely connected and free from damage. Try unplugging and re-plugging the device to reset it.

8. Maintenance

To ensure the longevity and optimal performance of your Enfizi Enf510 Call Blocker:

• Keep the device in a dry, dust-free environment.
• Clean the exterior with a soft, dry cloth. Avoid using liquid cleaners or abrasive materials.
• Do not attempt to open or repair the device yourself, as this will void the warranty.
