5. Safety Information
Please read and follow these safety guidelines to ensure proper operation and prevent damage:
- Do not operate the booster without both indoor and outdoor antennas properly connected.
- Ensure the outdoor antenna is installed at least 20 feet (6 meters) horizontally and 30 feet (9 meters) vertically from the indoor antenna to prevent oscillation.
- Use only the power supply provided with the booster.
- Avoid exposing the booster unit to extreme temperatures, moisture, or direct sunlight.
- Do not attempt to open or modify the booster unit. This will void the warranty and could cause damage.
- Register your signal booster with your wireless provider. Most providers require consent for booster use.
6. Setup Guide
Follow these steps for a successful installation of your Atcall 3K Cell Phone Signal Booster:
Step 1: Install the Outdoor Antenna
- Choose a location for the outdoor antenna that has the strongest existing cellular signal. This is typically on the roof or an exterior wall of your building.
- Mount the outdoor directional antenna securely using the provided mounting kit. Ensure it is pointed towards the nearest cell tower for optimal signal reception.
- Connect one end of the 60ft coaxial cable to the outdoor antenna.

Step 2: Place the Booster Unit and Indoor Antenna
- Route the other end of the 60ft coaxial cable from the outdoor antenna into your home and connect it to the designated port on the 3K Signal Booster unit.
- Connect the indoor whip antenna to the booster unit.
- Position the booster unit and indoor antenna in a central location within the area where you want to improve signal. The booster can be placed on a desktop or mounted on a wall using the provided bracket.

Step 3: Ensure Isolation and Power On
- Maintain sufficient separation between the outdoor and indoor antennas. A minimum of 20 feet (6 meters) horizontal and 30 feet (9 meters) vertical separation is recommended to prevent signal feedback (oscillation).
- Connect the power supply to the booster unit and then plug it into a power outlet. The booster will power on, and the LCD screen will activate.

7. Operating Instructions
Once powered on, the Atcall 3K Signal Booster's LCD screen provides crucial information about its operation:
- Real-Time Signal Strength (dBm): The display shows the uplink and downlink signal strength in decibels-milliwatts (dBm) for each supported frequency band. Higher (less negative) dBm values indicate stronger signals.
- Uplink/Downlink Gain: Indicates the amplification level for both outgoing and incoming signals.
- Frequency Band Operating Status: Shows which bands are active and receiving a signal.
- Norm Indicator: When the booster is operating normally, the 'Norm' indicator will be displayed.
Adjust the direction of the outdoor antenna slightly while observing the LCD screen to achieve the highest possible downlink signal strength (dBm) and gain for your desired frequency bands. This ensures the booster is receiving the best possible signal from the cell tower.

8. Troubleshooting
If you experience issues with your signal booster, refer to the following common problems and solutions:
- No Signal Improvement:
- Check the outdoor antenna's direction. Use the LCD monitor to fine-tune its position for maximum downlink signal strength.
- Ensure adequate separation between the indoor and outdoor antennas (at least 20ft horizontal, 30ft vertical). Insufficient isolation can cause oscillation and reduce performance.
- Verify all cable connections are secure and not damaged.
- Confirm your mobile device is operating on one of the supported frequency bands (12/17, 13, 5, 2/25, 4).
- LCD Display Shows Low Signal:
- The booster requires a minimum outdoor signal to function effectively. Before installation, ensure you have at least 1 bar of signal outside your home.
- Re-adjust the outdoor antenna to capture a stronger signal from the cell tower.
- Booster Not Powering On:
- Check the power supply connection to both the booster and the wall outlet.
- Ensure the power outlet is functional.
How to Test Your Phone's Frequency Band:
Understanding your phone's frequency band can help diagnose compatibility issues.
- For iPhone: Dial *3001#12345#* then press the call button. Navigate to 'All Metrics' and then 'Serving Cell Info' to check 'Band Info'.
- For Android Phone: Download a network cell info app (e.g., "Network Cell Info Lite"). Open the app, choose 'GAUGE', and then check 'BAND'.
