4. Before Installation: Check Your Band
Before installing, it is crucial to confirm that your phone operates on one of the supported frequency bands (4/5/7/12/17/66). The booster will only function if your phone's band is compatible.
For iPhone Users:
- Dial *3001#12345#* and press Call.
- Navigate to "Serving Cell Info."
- Check "Band Info" to identify the frequency band.
For Android Users:
- Download a network info app (e.g., "Network Cell Info Lite") from the Google Play Store.
- Use the app to find your current frequency band.

5. Installation Guide
Proper installation is key to the booster's performance. Follow these steps carefully.
5.1. Outdoor Antenna Placement
The outdoor antenna should be mounted at the highest point possible on your roof or an exterior wall, free from obstructions. It must be aimed towards the nearest cell tower to receive the strongest possible signal.
- Use the "Signal Advisor" app to locate the nearest cell tower and determine the optimal direction for the outdoor antenna.
- Securely mount the antenna using the provided hardware.

5.2. 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 (feedback).
- Mount the indoor antenna in a central location, typically on a wall or ceiling.
- Maintain a minimum vertical separation of 20 feet (6 meters) and a horizontal separation of 50 feet (15 meters) between the outdoor and indoor antennas. More separation is generally better.
5.3. Connecting Components
- Connect the outdoor antenna to the "OUTDOOR" port on the signal booster using the long coaxial cable.
- Connect the indoor antenna to the "INDOOR" port on the signal booster using one of the short coaxial cables.
- If routing cables through a window, use the provided 30 cm window cable to avoid drilling.
- Ensure all connections are finger-tight. Use waterproof tape for outdoor connections to protect against moisture.
- Plug the power adapter into the booster and then into a power outlet.

6. Operation
Once installed and powered on, the INVCALL signal booster will automatically begin to amplify signals. The Smart Touch LCD display provides real-time operational status.
6.1. Smart Touch LCD Display
The LCD screen shows critical information:
- FREQ (MHz): Displays the operating frequency band.
- GAIN (dB): Indicates the signal amplification level.
- Pout (dBm): Shows the output power.
- Isolation: Measures the separation between indoor and outdoor antennas. High isolation is crucial for stable operation.
- Band: Identifies the active frequency band.

7. Maintenance
The INVCALL signal booster requires minimal maintenance to ensure long-term performance.
- Cleaning: Periodically wipe the booster unit and indoor antenna with a soft, dry cloth. Do not use liquid cleaners.
- Cable Inspection: Annually inspect outdoor cables and connections for wear, damage, or loose fittings. Ensure waterproof tape is intact.
- Antenna Obstructions: Ensure the outdoor antenna remains free from new obstructions (e.g., tree growth, new buildings) that could block the signal path to the cell tower.
8. Troubleshooting
If you experience issues with your signal booster, refer to the common problems and solutions below. For further assistance, use the Signal Advisor app to contact technical support.
| Problem | Possible Cause | Solution |
|---|---|---|
| No signal improvement | Insufficient outdoor signal; improper antenna aiming; insufficient separation between antennas. | Verify outdoor signal strength with the app. Re-aim outdoor antenna. Increase separation between indoor and outdoor antennas. |
| Booster repeatedly turns on/off | Power adapter issue; oscillation (feedback). | Ensure power adapter is providing sufficient power. Increase antenna separation. Check for loose cable connections. |
| LCD shows "Isolation" warning | Indoor and outdoor antennas are too close, causing feedback. | Increase the physical distance (vertical and horizontal) between the indoor and outdoor antennas. Ensure no direct line of sight. |
| Specific band not boosting | Phone not operating on a supported band; booster not detecting the band. | Confirm your phone's band using the method in Section 4. Ensure outdoor antenna is receiving a strong signal on that band. |
