Preface This user’s manual describes the installation, commissioning and maintenance of wide band consumer boosters. Please do read user manual carefully before installing and maintaining the repeaters. The information in this manual is subject to change without prior notice. 1. Safety Warnings Users must follow the below principles： z Booster should follow system requirement of communication equipment, assure good grounding and lightning protection.
2. Why booster 2.1. Reason 1) Blind or weak signal areas are formed if the buildings are too far away from CELL TOWER, or the buildings themselves shield or absorb signals. 2) There are too many complicated signals in the higher part of the buildings, therefore ping-pong switching effect has been formed and the signals fluctuate a lot, there are annoying noises during phone calls and call drops accordingly. 3) Elevators and basements are well-known for blind areas.
Question: Will booster increase the RF radiation? A: No, it will decrease instead. As it can be searched easily through internet, the tower would “order” the mobile phone to increase its output power, in order to ensure successful connection when the mobile signal bar is few, there will be stronger mobile output power level when the mobile signal bar is less and the strongest one can reach 2W (GSM); moreover, the mobile phone is usually as near as less than 5cm to human body when people are in phone calls.
3. Introduction Our F10F-CP booster is the perfect solution for providing a wireless improvement in the cellular reception of a home, office, restaurant, VIP Room, apartment, building or shopping mall, in the quickest time possibly. One repeater covers 50 to 100 square meters.
4. System Characteristics 4.1. Features z Very cost effective solution for immediate coverage z Dual System to amplify CDMA and PCS systems z Support any cellular devices (voice & data & video) z SOHO solution for small sized areas z Power LED for power status z Universal power range of 100V~264V z Palm size elegant design and low power consumption z Manual gain control provides a variety of applications. z Auto automatic gain control to stabilize the coverage and minimize the noises.
5. Block diagram and work principle F10F-CP is basically a bi-directional booster, the downlink signals are received by the repeater from BTS by the donor antenna, filtered by its combiner, internal duplexers and FC unit, amplified by low noise amplifier (LNA) and downlink PA unit, and then sent via the server antenna to the coverage area. The bandwidth is wide band frequency.
6. The booster system Below diagram shows how simple and fast the booster system is installed and works effectively One Yagi antenna, as donor antenna, is installed at the top of the roof to pick up good mobile signals from the cell tower, and send through cable to the booster to amplify the signals significantly, and then the output signals are transmitted into area by the indoor antenna. Very clear phone call or high speed mobile data are immediately achieved within the area.

8. Installation F10F-CP boosters should be used to cover the indoor area. Humidity and temperature of working environment can affect the reliability of booster. So, temperature, humidity, dust , interference, power, space requirements and other factors should be considered during installation of booster. 8.1. Installation Location Requirement 1) It is appreciated that the booster is installed in a cool, dry and ventilated room without erosive gas and smoke and without leakage on its proof.
8.4. Installation of donor antenna The boostter’s main function is to improve weak RF signals of an area. A simple formula: Input power+ Gain= Output power. The signal strength from the outdoor antenna directly affects the efficiency of the indoor coverage. It is very important to choose the donor antenna location in order to get the best signals.
adjust the donor antenna direction to have balance between signals of different mobile operators or various mobile systems. Donor antenna installation ---Notes: z Do not install the donor antenna during the rainy day with lightning. z Please follow the instructions to install the donor antenna. z It is a must that the waterproof shall be done to connectors of donor antenna and feeder lines.

8.5. Cable layout and connector assembly 1) Keep the type, specifications, routing direction, location, and curvature radius of cables in compliance with the design requirement. Place cables in good order, bend them smoothly, and protect the outer skin against any damage. 2) Separate RF cables from power cables. Take proper isolation measures if they have to be placed on the same cable racks owing to the site condition restriction.
9. Booster Installation 9.1. Installation requirement 9.1.1. Installation Location Requirement 1) The booster shall be installed indoor in a cool, dry and ventilated room without erosive gas or smoke, or a cool and ventilated wall to ensure excellent heat dissipation 2) Installation height should be easy for RF cable wiring, heat dissipation, security and maintenance. 3) Have a set of independent and stable power supply. 9.1.2.
9.2.2. Booster’s ports description 1) Outdoor port: connected with the donor antenna by cable 2) Indoor port: connected with server antenna directly or by cable 3) DC IN: connected with power supply. 9.2.3. Accessories selection Please pay attention to the two points of “frequency” and “impedance” during the selection of the accessories. All accessories shall support the repeater’s frequencies from feeder line, antenna and splitter to combiners etc.
z Status Definition Green Normal Off DC power problem Status and Definition of ALARM indicators; Alarm LED only works for downlink signals Status ALARM It is working in linearity Green Warning: Input signals may be not enough, so please check on coverage effect, do not do anything if it is good; otherwise please adjust the repeater system to get better coverage. A little bit stronger input signals or slight self oscillation have occurred.
9.3.2. Manual Gain Control (MGC) DIP Switch can be used to adjust the booster gain when Alarm LED is orange or even RED. The principle is that booster alarm LED must be green color. Switches 1.2 represent Downlink and 3.4 represent Uplink. When it is necessary to adjust the gain by DIP switch, firstly please adjust Downlink gain according to input signals, secondly please adjust Uplink gain according to Downlink gain.
ALARM LED. If it shines “orange”, use 1dB as step to reduce the gain until “green” turns on, then increase the gain 1~3dB attenuation value until “orange” starts to turn on, then brings back 1~2dB till “green” is on, then fix the gain and the repeater’s downlink output power reaches the perfect status. If it shines “green” then, Please check coverage effect firstly, if the coverage effect is good, the engineering has reached expecting target, thus there is no need to do anything.
Check whether it is necessary to add more server antennas since barriers block the signal penetration, also check whether the repeater’s power is enough; please install more server antennas or replace with a repeater of higher power level. 2) If the signals in small part of the areas have not been improved, please check below: Check whether the service antenna is installed correctly or not, you may try to move the antenna location to improve coverage.
9.4.2. Booster can not comm unicate in Power-ON status 1) The power is on but it has a signal fluctuation or a flash signal. The phone call can not be achieved. It shall be caused by the insufficient isolation between donor antenna and serve antenna. Please take below measures: ¾ Firstly check whether the alarm LED is orange. The orange light shows the insufficient isolation. ¾ Secondly adjust the antennas’ directions or locations or enlarge the distance between them.
