3. Setup and Installation
Proper installation is crucial for optimal performance. Follow these steps carefully:
3.1. Outdoor Antenna Placement
The outdoor antenna should be mounted in a location with the strongest possible existing cellular signal, typically on the roof or an exterior wall. It must be pointed towards the nearest cell tower. Use the HiBoost Signal Supervisor app (available on App Store and Google Play) to locate the best signal source and assist with antenna alignment.

3.2. Indoor Antenna Placement
The indoor antenna should be placed in the center of the area where you need improved signal. Ensure there is sufficient separation between the indoor and outdoor antennas to prevent oscillation (signal feedback). A minimum of 20 feet vertical or 50 feet horizontal separation is recommended.

3.3. Connecting the System
- Connect the 50ft outdoor cable to the outdoor antenna and route it into your building.
- Connect the other end of the outdoor cable to the 'Outdoor' port on the HiBoost signal booster unit.
- Connect the 50ft indoor cable to the indoor antenna.
- Connect the other end of the indoor cable to the 'Indoor' port on the HiBoost signal booster unit.
- Connect the power supply to the booster unit and then plug it into a power outlet.

4. Operating Instructions
Once properly installed and powered on, the HiBoost SL 15K will automatically begin boosting the cellular signal. The LCD screen on the booster unit displays key information such as signal strength, band status, and any alerts.
- Power Indicator: Shows if the unit is powered on.
- Alarm Indicator: Lights up if there is an issue, such as oscillation or signal overload.
- ISO Indicator: Indicates isolation status between indoor and outdoor antennas.
- Signal Level Display: Shows the current uplink and downlink signal strength for each supported frequency band.
The Automatic Gain Control (AGC) system intelligently detects existing signal strength and adjusts the booster's performance for optimal results without manual intervention.

5. Maintenance
The HiBoost SL 15K is designed for minimal maintenance. To ensure longevity and optimal performance:
- Keep the booster unit in a dry, well-ventilated area, away from direct sunlight and extreme temperatures.
- Periodically check all cable connections to ensure they are secure and free from damage.
- Inspect the outdoor antenna for any physical damage or obstructions (e.g., heavy snow, debris) that might affect signal reception.
- Clean the exterior of the booster unit and antennas with a soft, dry cloth as needed. Do not use harsh chemicals or abrasive cleaners.
6. Troubleshooting
If you experience issues with your signal booster, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No Signal Boost / Weak Signal | Insufficient isolation between antennas, outdoor antenna not pointing to the strongest signal, or weak outdoor signal. | Increase separation between indoor and outdoor antennas. Adjust outdoor antenna direction using the Signal Supervisor app. Relocate outdoor antenna to a stronger signal area. |
| Alarm Light On | Oscillation (feedback) or signal overload. | Ensure adequate separation between antennas. Check for strong signal sources too close to the indoor antenna. The AGC system should automatically adjust, but manual intervention may be needed if the alarm persists. |
| No Power | Power adapter disconnected or faulty. | Check power connections. Ensure the power outlet is functional. Try a different power adapter if available. |
| App Connectivity Issues | Bluetooth/Wi-Fi connection problem. | Ensure Bluetooth/Wi-Fi is enabled on your device. Restart the app and the booster unit. Check your network connection. |
