5. Pre-Installation Checklist

Before beginning installation, ensure the following:

• Outdoor Signal Strength: The booster requires an existing outdoor signal to amplify. Ensure you have at least one bar of stable outdoor signal where the outdoor antenna will be placed.
• Frequency Band Compatibility: Confirm your phone operates on one of the supported frequency bands: 12/17, 13, 5, 4/66, or 2/25. You can check this using the methods described in Section 6.4.
• Required Tools: Gather necessary tools such as a drill, ladder, cable ties, and a wrench.
• Location Planning: Identify optimal locations for the outdoor antenna, indoor antenna, and booster unit to maximize separation and signal coverage.

6. Setup and Installation Guide

Follow these steps for proper installation of your SignalBrick K01 Pro Cell Phone Booster.

6.1. How the System Works

The SignalBrick K01 Pro system works by capturing existing outdoor cellular signals, amplifying them, and then rebroadcasting the stronger signal indoors. Conversely, it captures indoor signals from your devices, amplifies them, and sends them back to the cell tower.

Image: How the Booster Works (Internal). This image illustrates the booster unit acting as an intermediary, connected to both the outdoor and indoor antennas, processing the signal.

6.2. Outdoor Antenna Placement

The outdoor antenna should be mounted at the highest point possible on your building, such as a roof or pole, and pointed towards the nearest cell tower. Ensure there is a clear line of sight to the tower if possible. The goal is to capture the strongest possible signal.

• Use the provided mounting bracket to secure the outdoor antenna.
• Point the antenna in the direction of the strongest outdoor signal. You may need to use a signal strength app on your phone or observe the booster's LCD display during tuning.
• Ensure the outdoor antenna is at least 30 feet (9 meters) horizontally and 20 feet (6 meters) vertically away from the indoor antenna to prevent oscillation.

6.3. Indoor Antenna and Booster Unit Placement

The indoor antenna should be placed in the center of the area where you need improved signal. The booster unit should be placed in a well-ventilated area, away from direct sunlight and heat sources.

• Connect the 60ft coaxial cable from the outdoor antenna to the "OUTSIDE" port on the booster unit.
• Connect the indoor antenna to the "INSIDE" port on the booster unit.
• Ensure the indoor antenna is positioned to cover the desired area. Avoid placing it in a corner or behind large obstructions.
• Maintain the recommended separation distance between the indoor and outdoor antennas.

6.4. Checking Frequency Bands

To ensure your device is compatible and to assist with troubleshooting, you can check your phone's frequency band information:

• For iPhone:
  1. Dial *3001#12345#* then press the call button.
  2. Choose "All Metrics" and then "Serving Cell Info".
  3. Check "Band Info" to identify the active frequency band.
• For Android Phone:
  1. Download a network information app, such as "Network Cell Info Lite".
  2. Open the app and navigate to the "GAUGE" section.
  3. Check the "BAND" information displayed.

6.5. Powering On and Initial Check

Once all antennas and cables are connected, plug in the power supply to the booster unit and then into a power outlet. The booster will perform a self-test. Observe the LCD display for operational status.

• The LCD will show real-time signal strength and operational status for each band.
• A "NOR" (Normal) indicator means the band is operating correctly.
• An "OSC" (Oscillation) indicator means there is interference between the indoor and outdoor antennas. Refer to the Troubleshooting section.

7. Operating Instructions

The SignalBrick K01 Pro operates automatically once powered on and properly installed. The Smart LCD Display provides continuous feedback on its performance.

• Monitoring Signal: The display updates every 1.5 seconds, showing the current signal gain for each active frequency band. Higher negative numbers (e.g., -70 dBm) indicate a stronger signal than lower negative numbers (e.g., -100 dBm).
• Status Indicators:
  • NOR (Normal): Indicates stable operation for that frequency band.
  • OSC (Oscillation): Indicates feedback interference. This requires adjustment of antenna separation or orientation.
• Optimal Performance: For best results, ensure all active bands show "NOR" and the signal strength readings are as high (closer to 0) as possible.

8. Maintenance

The SignalBrick K01 Pro requires minimal maintenance.

• Cleaning: Periodically wipe the booster unit and antennas with a soft, dry cloth. Do not use liquid cleaners or solvents.
• Cable Inspection: Annually inspect all cable connections for wear, damage, or loose fittings. Ensure outdoor cables are properly sealed against weather.
• Antenna Position: Verify that outdoor and indoor antennas remain securely mounted and correctly oriented.
