Setup and Installation
Proper installation is crucial for optimal performance. Follow these steps carefully:
1. Check Your Current Signal Band
Before installation, confirm that your phone's frequency band is compatible with the booster (Bands 2, 4, 5, 12, 13, 17, and 25). The booster will only work if your phone operates on one of these bands.

2. Outdoor Antenna Placement
The outdoor directional antenna should be mounted in a location where it can receive the strongest possible signal from the nearest cell tower. Use the ANNTLENT Signal Advisor APP to find the best location and direction for the outdoor antenna. This app provides real-time signal strength and direction information.

Ensure the outdoor antenna is pointed directly towards the cell tower. Secure the antenna firmly to prevent movement due to wind or other environmental factors. Use the provided waterproof tape for outdoor cable connections to protect them from moisture.

3. Indoor Antenna Placement
Mount the indoor panel antenna on a wall within the area where you need improved signal. The indoor antenna should be placed as far as possible from the outdoor antenna to prevent oscillation (feedback loop) and ensure maximum coverage. A minimum separation of 20 feet vertically or 50 feet horizontally is recommended.

4. Connecting the Components
- Connect the outdoor antenna to the "OUTDOOR" port on the booster unit using one of the provided coaxial cables.
- If drilling through walls is not desired, use the flat window entry cable to pass the outdoor antenna cable into your home without drilling.
- Connect the indoor antenna to the "INDOOR" port on the booster unit using another coaxial cable.
- Connect the power supply to the booster unit and then plug it into a power outlet.

Use the cable management tape to neatly secure cables and prevent tripping hazards.

Operating the Booster
Once all components are connected and powered on, the booster will automatically begin to amplify the cellular signal. The integrated screen on the booster unit provides real-time information about its operation, including signal gain and output power.

Automatic Gain Control (AGC)
The booster features Automatic Gain Control (AGC) which optimizes the signal gain automatically to prevent overload and ensure stable performance. This means the booster adjusts itself to provide the best possible signal without manual intervention.

Manual Gain Control
For specific signal environments, the booster also offers manual gain control, allowing you to customize the booster's settings to meet individual signal needs. Refer to the on-screen display for guidance when making manual adjustments.

Standby Mode
The booster is designed with a standby mode to reduce power consumption when not actively boosting a signal, contributing to energy efficiency.

Maintenance
The ANNTLENT N70-PL signal booster requires minimal maintenance. Keep the unit and antennas clean and free from dust or debris. Periodically check all cable connections to ensure they are secure and free from damage, especially outdoor connections which should remain waterproofed.
No user-serviceable parts are inside the booster unit. Do not attempt to open or repair the device, as this will void the warranty.
Troubleshooting
If you experience issues with your signal booster, consider the following common solutions:
- No Signal Improvement:
- Ensure the outdoor antenna is pointed directly at the nearest cell tower. Use the Signal Advisor APP to verify direction and signal strength.
- Check all cable connections to ensure they are tight and properly connected to the correct ports (OUTDOOR to outdoor antenna, INDOOR to indoor antenna).
- Verify that there is at least 1 bar of existing signal outside your home. The booster amplifies existing signal; it does not create signal where none exists.
- Increase the separation distance between the indoor and outdoor antennas to prevent oscillation.
- Confirm your phone's frequency band is supported by the booster (Bands 2, 4, 5, 12, 13, 17, 25).
- Reduced Coverage Area:
- The actual coverage area depends on the strength of the outside signal. More bars outside generally lead to larger coverage inside.
- Building materials (concrete, metal) can significantly reduce indoor coverage. Try repositioning the indoor antenna.
- Booster Displaying an Error:
- Refer to the booster's screen for specific error codes or messages. Consult the Signal Advisor APP for further diagnostic information or online support.
