Follow these steps to install your Clear TV Key antenna:

3.1. Connecting to a TV with a Digital Tuner

1. Identify TV Antenna Input: Locate the antenna input port on the back of your television. Determine if it is a horizontal or vertical configuration.

2. Mount the Antenna: The TV Key antenna should be mounted in a vertical position, extending upward. If your TV's antenna connection faces downward, use the provided right-angle coaxial connector.

3. Connect the Antenna: Screw the antenna connector directly into the "Antenna In" or "Cable IN" port on the back of your TV. If a right-angle connector is needed, attach it to the antenna first, then to the TV. Ensure the antenna is vertically mounted and connectors are tightened securely.

Note:

• After installation, you can use your Set-Top Box (if applicable) to check signal strength and quality.
• If the picture is not steady, adjust the antenna's position to achieve better reception.
• The Clear TV Key is recommended for use with TV transmitting stations located within 10-25 miles. Signal reception can vary based on geographical location, building materials, and local interference.

4. Operating Instructions

Once installed and channels are scanned, your Clear TV Key antenna will allow you to receive free digital and HD broadcast television channels. The antenna enhances TV signals, providing access to local news, weather, sports, and other programming without monthly fees or contracts.

The primary function of this product is signal enhancement. The number and quality of channels received are directly related to your distance from broadcast towers and local environmental factors.

In the event of a power outage, the Clear TV Key can continue to function as long as your television and any connected Set-Top Box have power.

  • Ensure the antenna is mounted vertically as recommended.
• Limited Number of Channels:
