- Band Switch: Allows selection or deselection of specific frequency bands.
4. Guide Setup
Proper installation is crucial for optimal performance. Follow these steps carefully.
4.1 Kontrola Pêş-Sazkirinê
- Check Outdoor Signal Strength: Before installation, ensure you have at least 1-2 bars of existing outdoor signal. The booster amplifies existing signal; it does not create signal where none exists.
- Identify Your Carrier's Frequency Band: Use your cell phone to determine the frequency band your carrier uses.
- Ji bo iPhone: Dial *3001#12345#* then press the call button. Click "All Metrics," then "Serving Cell Info," and check "Band Info."
- Ji bo têlefonê Android: Download "Network Cell Info Lite" from your app store. Choose "GAUGE" and then check "BAND."

4.2 Gavên Sazkirinê
- Antena derve saz bike:
- Choose a location on your roof or an exterior wall that has the strongest existing cellular signal.
- Mount the directional outdoor antenna using the provided mounting kit. Ensure it is pointed towards the nearest cell tower.
- Maintain a minimum horizontal distance of 20 feet (6 meters) and a vertical distance of 20 feet (6 meters) between the outdoor antenna and the indoor booster unit. A straight-line distance of over 30 feet (9 meters) is recommended.
- Install the Indoor Booster Unit:
- Place the booster unit (with built-in indoor antenna) in a central location within your desired coverage area.
- Ensure the unit is positioned away from metal objects and other electronic devices that may cause interference.
- Kabloyan girêdin:
- Connect one end of a 30ft RG6 cable to the outdoor antenna.
- Route the cable indoors and connect the other end to the "Outdoor" port on the booster unit.
- Ensure all connections are finger-tight.
- Hêza girêdanê:
- Connect the power adapter to the booster unit's power input.
- Adaptera elektrîkê têxin nav dergehek elektrîkê ya standard.
- Hêzdar û Çavdêr:
- The booster will power on, and the LCD screen will display real-time signal information.
- Adjust the outdoor antenna's direction slightly while monitoring the LCD display to achieve the highest possible downlink signal strength (dBm) and gain.

5. Telîmatên Operating
Once installed and powered on, the Atcall Fast Link Cell Phone Booster operates automatically. The LCD display provides continuous feedback on its performance.
5.1 Çavdêriya Performansê
- The LCD screen will show the signal strength (dBm) for each supported band. A higher (less negative) dBm value indicates a stronger signal.
- Observe the uplink and downlink gain values. These indicate the amplification provided by the booster.
- If a band is not showing activity or has low signal, ensure the outdoor antenna is correctly aimed and there is sufficient isolation between the indoor and outdoor antennas.
5.2 Band Selection (if applicable)
The booster typically operates on all supported bands simultaneously. If you need to disable a specific band, use the "Band Switch" function on the LCD display as indicated in Figure 3.1.
