3. Setup Instructions
Follow these steps to set up your ANTOP SBS-602B Smart Boost Antenna Amplifier:
- Connect Your Antenna: Connect the coaxial cable from your non-amplified TV antenna to the "ANT.IN" port on the ANTOP SBS-602B amplifier.
- Connect to Devices: Use one of the provided 5ft coaxial cables to connect the "TV/FM Device" output port on the amplifier to your primary television's antenna input. If connecting a second device (e.g., FM stereo, another TV, or streaming device), use the second 5ft coaxial cable to connect it to the other "TV/FM Device" output port.
- Connect Power: Plug the AC/DC Power Adapter into the "DC 12V" input port on the amplifier, then plug the adapter into a standard electrical outlet. The LED indicator on the amplifier should illuminate.
- Positioning: Ensure your antenna is positioned optimally for signal reception. Keep the antenna away from metallic objects and high-power consumption devices to prevent interference.

4. Operating Instructions
The ANTOP SBS-602B features a Smart Boost dial to adjust the signal gain:
- Adjusting Gain: Turn the Smart Boost dial clockwise to increase the signal gain (boost reception). Turn the dial counter-clockwise to decrease the signal gain. The adjustable range is 0 to 10dB.
- Channel Scan: After each adjustment of the Smart Boost dial, it is crucial to perform a channel scan on your television or connected device. This allows your device to detect and save the newly optimized channels.
- Regular Scans: It is recommended to scan for channels monthly to ensure you receive all available channels, including any newly added or changed broadcasts in your area.

5. Maintenance
To ensure the longevity and optimal performance of your ANTOP SBS-602B amplifier:
- Cleaning: Use a soft, dry cloth to clean the exterior of the amplifier. Do not use liquid cleaners or abrasive materials.
- Environment: Keep the amplifier in a dry environment, away from direct sunlight, moisture, and extreme temperatures.
- No User Serviceable Parts: Do not attempt to open the amplifier casing or perform any repairs yourself. This could void your warranty and cause damage to the unit.
6. Troubleshooting
If you experience issues with your ANTOP SBS-602B amplifier, consider the following:
- No Signal or Poor Reception:
- Ensure all coaxial cable connections are secure at both the amplifier and your TV/devices.
- Verify the power adapter is firmly plugged into the amplifier and a working electrical outlet. The LED indicator on the amplifier should be lit.
- Adjust the Smart Boost dial and perform a channel scan on your TV after each adjustment.
- Check your antenna's outdoor or indoor placement. Obstructions or proximity to metallic objects can affect signal quality.
- Keep the antenna and amplifier away from high-power consumption devices (e.g., microwaves, refrigerators) that can cause electromagnetic interference.
- Wobbly Power Connection: Ensure the power adapter plug is fully inserted and secure. If the connection remains loose, contact customer support.
- Limited Channels After Setup: Remember to perform a full channel scan on your TV after connecting the amplifier and adjusting the gain.
