Chapter 1 Safety Warning
Users must follow the below principles:
1. Repeater should follow system requirement of communication equipment,
assure good groundings and lightning protection.
2. The power supply voltage of repeater should meet the standards of
security requirement; any repeater-operator can operate only after
cutting power in advance. Only the professional can operate electrified.
3. Do not dismantle machine, maintain or displace accessories by yourself,
because in this way, the equipment may be damaged or even get an
electric shock.
4. Do not open the repeater, touch the module of repeater, even not to open
the cover of module to touch the electronic component, the
components will be damaged due to electrostatic
5. Please keep away from heating-equipment, because the repeater will
dissipate heat when working. And do not cover repeater with anything
that influences heat-dissipation.

Chapter 4 Installation
4.1 Installation requirements
Outdoor repeaters BOSSGSM-GDU-HP33 are mainly applied as indoor coverage
system, the changes of air moisture and temperature may influence its reliability. So
such factors as the temperature, air moisture, dustproof, current source and space
requirement, etc shall be fully considered during installation.
Position selection
Install in the place that is not easy to be reached by irrelevant people.
Install at the place that is convenient for power supply and cabling.
Avoid heat source and moist environment
Install at drought space, hang on wall vertically in order to assure good heat distribution.
Power supply requirement
AC power supply of 9~265V/50±5Hz
4.2 Installation
Picture 4.1 Installation diagram

Picture 4.2 Hole positions
Installation Steps:
A) Use percussion drill to make four Φ4 holes on the wall according to above hole diagram.
B) Fill the holes with expanding plug
C) Put the tapping screw through the holes and fit tightly with the expanding plug,
and fasten the repeater onto the wall.
D) Make sure that the installation is firm and correct
4.3 Connection
Connection of RF cable
BTS Port : donor antenna cable is connected with BS Port;
MS Port : service antenna cable is connected with MS Port;
Grounding
Please connect one end of a copper wire with the intersection size of 16mm2 with
the grounding screw, and the other end with the grounding system of the building. It is
requested that the grounding impedance shall be less than 10Ohm.
Power supply connection
Installation of air switch is recommended for the convenience of power supply switch off.
Please use three-pin plug to assure good grounding
Please use the grounding screw, nut, washer to connect the grounding wire and
repeater shell

Lightening Arrestor can be installed if necessary
Picture 4.3 Power supply connection
4.4 System inspection
The followings should be checked after installation:
Grounding impedance<10Ω;
Antenna socket, cable are well grounded;
Power supply lightening protection
Building lightening protection
Antenna lightning Protection.

Chapter 5 Repeater setting
Please check whether the connection of RF cable is correct (donor antenna
connected to BTS port, service antenna connected to MS port), and whether every port
is stable. After affirmation, please go along the followings:
5.1 Power supply connection
After power supply connection, check ALARM and POWER indicators first.
Status and definition of POWER indicators:
Status and definition of ALARM indicators:
Status
Definition of ALARM
Green
Meaning: working in linearity
attention: Input signals may be not enough
Red
Meaning: overloading or self oscillation, strong input signals
Attention: cut the connection of equipment and service
antenna,then connect the MS port to load, if the red light
changes to green or orange, which means the isolation of
donor antenna and service antenna is not enough, then
please adjust the isolation.
If the red light still turning on that means over accepting of
donor antenna or strong interference, then please
adjust the
place of donor antenna..
Orange
Meaning: it is working in linearity
Notice: Please adjust MGC to increase the attenuation
value, till you find the “edge point”, and let the repeater work
at this point.

Pinput Power -VATT: input power—attenuation value

Downlink gain setting
As for the downlink working performance, “orange” is a good working point. At this
time, downlink output power and coverage effect are stable.
But from another point of view, we hope the equipment is as far as possible away
from overloading status of “red” (thus the equipment would hold higher interference
depression ability). So we try our best to set the equipment near “edge point” when
engineering.
Setting of “edge point”: (Switch on the power supply after connection with donor
antenna and coverage antenna, and observe ALARM indicator.)

■If it shines “orange”, use 1dB as stepping to increase attenuator until “green”
turns on, then decrease 1~3dB attenuation value until “orange” turns on. The
setting of downlink gain can reach the perfect status.
■If it shines “green” then,
◆To check whether the attenuation value has been set, if it is, use 1dB as
stepping to decrease attenuation until the “orange” turns on, then the downlink gain
can reach the perfect status.
◆But if attenuation is not set, it indicates that the input power is not enough.
Then please check coverage effect first, if the coverage effect is good, the
engineering has reached expecting target
But if the coverage effect is not so good, the donor antenna should be adjusted until “orange”
turns on or the effect reaches the target.
Uplink gain setting
Uplink gain is set based on downlink gain..
Standards: uplink attenuation value=downlink attenuation value

Chapter 6 Engineering Maintenance
6.1 Operation and maintenance
Equipment Disassembly
Close the outside air switch
Plug off the power supply
Cleaning
Close the outside air switch
Plug off the power supply.
Do not use liquid materials to clean the equipment to avoid short circuit;
Please use dry dishclout
Grounding
Using grounded power plug (three-pin plug)
Power supply
Please make sure the voltage and frequency comply with the repeater requirement.
Component replacement
Please do not maintain or replace components by yourself, otherwise may get
an electric shock. Only the authorized professional can maintain and replace the
components.
Waterproof and moist proof
Please do not turn on or off the booster in moist environment when its door is
opened.
6.2 Emergency dealing
Switch off is recommended during following situations:
The power supply is not normal
