■Warning
Do not modify, disassemble or remove the cover. These actions could cause electrical
shock. We shall never be responsible for any problems caused by your reconstruction or
modification.
Do not touch the internal components. They may have high voltage or high temperature.
You may get electrical shock or burnt.
When the system is operating, keep your hands and face away from it. Otherwise, you
may get injured by an accident.
■Caution
Please read catalogue and instruction manual carefully before use.
Use the products within the specified input voltage, temperature and humidity. Use of
products in non-specified condition may damage the product.
Connect the frame ground terminal to the ground terminal of the device for safety. Use

Preface
GZF850-VL Repeater is widely used for constructing a hybrid mobile communications
network. It receives and amplifies forward and reverse Radio Frequency (RF) signal to
extend the coverage of base station. This user manual covers the system frame, technical
specification, operation and maintenance of software of the repeater.

1.2 Product Features
Excellent RF performance: FiberHome provides wireless repeaters with
state-of-the-art performance such as minimized noise figure, time delay and IMD,
excellent link balance and out-of-band suppression.
Modular design: Modular design is easier for operators to make upgrade and
maintenance.
Monitor and control (M&C): The interior M&C module is the core to control the whole
repeater and implements four functions: detection, control and communication.
Perfect query, statistic and report: It can support query, statistic and report for the
history data including log, repeater data and query data etc.
Reliability: Industrial-level components are used, which can sustain a temperature
range of -25°C ~ +55°C (for outdoor repeater only) so that the product can work
reliably in a wide range of environments; the power supply of the integrated system is
designed with high redundancy to make sure that the power module can work under
normal load in 55°C and start normally in -25°C; the repeater is provided with
multi-level lightning protection devices to ensure reliable lightning protection for the
power supply, antenna and feeder. The lightning protection device of the power supply
is a combination of a gas discharge tube and a piezo-resistor and is designed with
2-level protection, so that it can absorb very high lightning strike energy as well as
remove residual voltage satisfactorily.

2. Applications
Accessing the signal by using a small Yagi antenna or Logarithm period antenna, low
power repeater amplifies the signal and combines the indoor distribution system,
which quickly improve the signal in shadowy or blind zones.

3. Installations
Sketch Map
Firstly, select an appropriate position to mount. The signal booster is better to be
mounted close to walls.At the position selected, punch a hole in the wall as shown
in the diagram and aim the bolt at the hole. Then fasten and fix with expansion
bolts.
To be connect the service ANT Port with out door reverse antenna through radio
frequency cable. In general, the reverse antenna is mounted at a higher position.
Yagi antenna and panel antenna may be used. The main lobe of the antenna
radiation is oriented towards the base station and the reverse antenna and base
station antenna should be visible as possible.

Connect donor ANT Port with the ports of indoor covering system or indoor relay
antenna. In general, the indoor covering system is composed of several splitters,
couplers, expansion amplifiers and antennas and applied as per specific
engineering design for the purpose of satisfying the signal covering demands in
large area or complicated terrain indoor space. In the case of small area indoor
space, the requirements for covering can be satisfied by using single relay
antenna with the option of hanging antenna or ceiling antenna.
Finally, connect the power interface shown as in the diagram to power adapter
and power on the adapter with 220V AC. The signal amplifier installation is thus
completed.
4. Site Commissioning
Note: Please excuse us for not giving any further notice about any changes of
operation. FiberHome privileges to the final explanation of EMS.
Our EMS has two sets of software, one is local version monitor software, and the
other is the SQL version monitor software. We take local version software as an
example to explain how to configure the parameters.
In the local version software has two parts: communication server and monitor
software. It is applicable in the windows2000, and windows XP operation system.
