F27/F23/F20-5S are designed to help mobile users amplify weak signals of 2G, 3G and 4G. They are bi-directional amplifiers. The donor antenna receives the signals from the cell tower, amplifies it, and transmits to the signal booster. Then the indoor antenna will receive the signal and retransmit it to your mobile device. The signals produced by your phone are also amplified by the indoor antenna via the booster and donor antenna. No.

Embedded CPU, self-adaptive intelligent system to make booster system very easy to install and better performance is guaranteed under complex and constantly changing RF environment.
After power on the repeater, the display area of working frequency will light all the time, the working frequency will display in turn. “ISO” Isolation alarm indication. When the repeater doesn’t have enough isolation between the outdoor and indoor antennas, the “ISO” is flashing. Vice Versa, the “ISO” is off. ”AlC” Strong receiving power alarm indication. When the repeater’s receiving too strong signal from outside, output power gets overrated and “AlC” starts flashing.
• Make sure the place where you install the booster is near to one existing electrical outlet. It should also be well ventilated, away from excessive heat, moisture, and direct sunlight. Install tools and accessories: No.
1. Outdoor Antenna 2. Booster 3. Indoor Antenna 1. Install Outdoor Antenna 1.1 How to find the position with the strongest receiving signal The booster’s main function is to improve weak RF signal inside a house, office or any other indoor area. The receiving strength of the outdoor antenna and the strength of the signal reception outdoors directly affect the efficiency of indoor coverage.
Remark: when ALC shows up flashing, it means the receiving signal power is stronger than the system needs it. It is recommended to adjust outdoor antenna position unless ALC alarm disappears. Or you can leave it as it is to let the booster self-adjust automatically. However when ALC flashes, and the displayed gain is more than 30 dB less than rated gain value, try to adjust outdoor antenna to decrease the receiving power.
help on successful phone call connections or higher speed data services. 1.2 Install Outdoor Antenna In most cases, the panel antenna is the best choice. You can also choose wide band YAGI antenna as an option. There are 2 types of installation: wall mount or pole mount. Install outdoor panel antenna onto the wall for your reference: Step1: Unscrew antenna from L-mounting bracket on antenna base with wrench. Step2: Mount vertical plate of the L-bracket on the wall with supplied screws.
When you choose Indoor ceiling omni antenna or whip antenna, the best place to install it is the center of your house as the graph shows. 3. Install the signal booster Step1: Select an indoor location near to a power outlet on a wall. Step2: Mount the booster with the screws included as shown in the figure. Step3: Connect the outdoor antenna cables to booster connector marked “outdoor”. Tighten the connection with hand or wrench.
the booster system is completed. You can check the output power displayed in LCD. It may vary at 1~3dB difference which is normal due to outdoor signal conditions. It would be perfect that the output power reaches its rated one for largest coverage; but you can always leave it even though it doesn't as long as the coverage is good enough for you. In case the coverage is not enough, please take below measures as per below conditions. 1.
antenna and donor antenna point opposite direction). Reduce the booster’s downlink gain by the control button. Keep the uplink attenuation value and downlink attenuation value same then restart the booster. More about "ISO" indication ISO status indicates if the booster has enough isolation between outdoor and indoor antennas in order to avoid loop back or so-called self-oscillation.
gain to get stronger receiving signal Flashing but actual gain is not more than 30dB Full output power Working properly less than rated gain Working properly, but too strong signal, actions are recommended: Flashing but actual gain is more than 30dB less than rated gain 1. Adjust the antennas’ directions or Too strong locations to lower down input power. receiving signal 2. Reduce the booster’s gain by external attenuator or replace with lower gain antenna if the above methods don’t work.
3. Use the barrier like walls to increase the isolation. Flashing LCD screen 4. Reduce the booster’s gain by external attenuator or replace with lower gain antenna if the above methods don’t work. Problem Resolution The signal booster has no power. Check that the AC outlet is working. Try to fasten the connections between the different parts of the system.
