Introduction
The CPR Call Blocker Shield is designed to help users manage and block unwanted telephone calls. This device comes pre-programmed with a database of known scam numbers and allows for additional numbers to be blocked manually. It is intended for use with traditional landline phone systems and requires an active Caller ID service from your telephone provider for full functionality.

Setup Instructions
Follow these steps to correctly install your CPR Call Blocker Shield:
- Verify Caller ID Service: Ensure that you have an active Caller ID service from your telephone provider. This device relies on Caller ID information to function properly.

- Connect Call Blocker:
- Connect the telephone line from your wall socket into the port labeled "LINE" on the CPR Call Blocker Shield.
- Connect your telephone handset or base unit into the port labeled "PHONE" on the CPR Call Blocker Shield.

Operating Instructions
The CPR Call Blocker Shield offers several methods for blocking unwanted calls.
Automatic Blocking
The device comes pre-programmed with a database of 2000 known scam numbers. It also automatically blocks calls identified as International, Withheld, Unavailable, or Unknown. These calls will not ring through to your phone.
Manual Blocking (During a Call)
To block a number while a call is in progress:
- Using the Device Button: Press the large red BLOCK NOW button on the CPR Call Blocker Shield. The call will be disconnected, and the number will be added to your personal block list.
- Using a Cordless Phone: If you are using a cordless phone, press #2 on your phone's keypad. The call will be disconnected, and the number will be added to your personal block list.
The device can store an additional 1500 numbers on your personal block list.
Blocking Specific Area Codes
The CPR Call Blocker Shield allows you to block entire area codes. Refer to the device's on-screen menu (if available) or consult the full user manual for detailed instructions on how to add area codes to the block list.
Maintenance
The CPR Call Blocker Shield requires minimal maintenance.
- Cleaning: Wipe the device with a soft, dry cloth. Do not use liquid cleaners or abrasive materials.
- Placement: Ensure the device is placed on a stable, flat surface, away from direct sunlight, heat sources, and moisture.
- Software Updates: The device's pre-programmed scam number list is updated periodically. Check the manufacturer's website for information on how to update your device, if applicable.
Troubleshooting
If you encounter issues with your CPR Call Blocker Shield, refer to the following common solutions:
- No Dial Tone / Phone Not Working:
- Verify all cables are securely connected to the correct ports ("LINE" to wall, "PHONE" to telephone).
- Ensure your telephone line is active and functioning independently of the call blocker.
- Confirm that your telephone service provides in-line power, as some services (e.g., certain fiber optic setups like Verizon Fios) may not, which can affect the device's operation.
- Calls Are Not Being Blocked:
- Caller ID Service: The CPR Call Blocker Shield requires an active Caller ID service from your telephone provider. Without Caller ID, the device cannot identify incoming numbers to block.
- Manual Blocking: Ensure you are pressing the BLOCK NOW button on the device or #2 on your cordless phone during an unwanted call.
- Block List Capacity: The device has a limit of 1500 manually blocked numbers. If your list is full, you may need to manage existing entries.
- Blocked Calls Still Ring Once: Some telephone systems may allow a single ring before the call blocker intercepts and disconnects the call. This is normal operation for certain configurations.
- Interference with Caller ID Display: If your phone's Caller ID display is affected, ensure the call blocker is correctly installed and not causing a line impedance issue. Try connecting the phone directly to the wall to rule out the call blocker as the cause.
