3. Pre-Installation Checklist
Before purchasing or installing the booster, please ensure the following conditions are met for optimal performance:
- Signal Strength: Check that your outdoor signal is between -100dBm and -120dBm (approximately 1-2 bars). The booster cannot create a signal where none exists.
- Frequency Bands: Confirm your phone supports the following frequency bands: Band 2/4/5/12/13/17/25.
- Cell Tower Proximity: Verify that a compatible cell tower is within 3-5 miles of your location.
- Installation Requirements: Be prepared for mounting an outdoor antenna and routing cables, which typically takes 1-2 hours.
- Hotspot Devices: Note that hotspot devices cannot be boosted by this system.



4. Installation Guide
4.1. General Installation Principles
- Maintain adequate separation between the outdoor and indoor antennas to prevent oscillation. A minimum horizontal separation of 30 feet and a vertical separation of 13 feet is recommended.
- The outdoor and indoor antennas should face opposite directions to maximize isolation.

4.2. Outdoor Antenna Installation
The directional outdoor antenna should be mounted in a location with the clearest line of sight to the nearest cell tower. Use the HiBoost App (Signal Supervisor) to assist in finding the best signal direction.

4.3. Booster Unit and Indoor Antenna Connection
Connect the outdoor cable from the outdoor antenna to the designated port on the Hero Signal Booster unit. Then, connect the indoor antenna cable to the indoor port on the booster. The booster unit features an LCD color screen that simplifies installation by providing real-time signal indicators.
The kit includes two indoor antenna options:
- Panel Antenna: Provides extended coverage up to 3000 sq.ft, ideal for larger spaces. Typically wall-mounted.
- Whip Antenna: Compact and designed for desktop or mobile applications, covering up to 2000 sq.ft.


4.4. Cable Routing
The kit includes through-window cables (SMAM-SMAF) to avoid drilling holes for cable entry. These flat cables can be routed through window sills and connected to the indoor cable.
5. Operating Instructions
Once installed, the Hero Signal Booster operates automatically. The LCD color screen on the booster unit provides real-time information on signal strength and performance for each supported band. The HiBoost App (Signal Supervisor) allows for remote monitoring and fine-tuning of the booster's performance.

6. Maintenance
Regularly check all cable connections to ensure they are secure. Keep the booster unit and antennas clean and free from dust or debris. Avoid placing the booster in areas with extreme temperatures or high humidity.
7. Troubleshooting
If you experience any issues with your HiBoost Hero Cell Phone Signal Booster, the HiBoost App offers one-on-one live tech support and guidance. The app can help diagnose problems and recommend adjustments for optimal booster performance. Common issues and their potential solutions are also detailed in the full user manual.
