0.5 SAFETY NOTICES AND ADMONISHMENTS
This document contains safety notices in accordance with appropriate standards. In the interests of
conformity with the territory standards for the country concerned, the equivalent territorial admonishments
are also shown.
Any installation, adjustment, maintenance and repair of the equipment must only be carried out by trained,
authorized personnel. At all times, personnel must comply with any safety notices and instructions.
Specific hazards are indicated by symbol labels on or near the affected parts of the equipment. The
labels conform to international standards, are triangular in shape, and are colored black on a yellow
background. An informative text label may accompany the symbol label.
Hazard labeling is supplemented by safety notices in the appropriate equipment manual. These notices
contain additional information on the nature of the hazard and may also specify precautions.
Warning:
These draw the attention of personnel to hazards that may cause death or injury to the operator or others.
Examples of use are cases of high voltage, laser emission, toxic substances, point of high temperature,
etc.
Alert:
These draw the attention of personnel to hazards that may cause damage to the equipment. An example
of use is the case of static electricity hazard.
Caution notices may also be used in the handbook to draw attention to matters that do not constitute a
risk of causing damage to the equipment but where there is a possibility of seriously impairing its
performance, e.g. by mishandling or gross maladjustment. Warnings and Cautions within the main text do
not incorporate labels and may be in shortened form.
CAUTION: danger of explosion if battery is incorrectly replaced. Replace only with the same or equivalent
type.
Cautions:
Risk of explosion: if battery is replaced by an incorrect type. Dispose of used batteries according to the
instructions.
The repeater is allowed to be operated only with permission of the network operator. This equipment
needs professionals to install and debug accordingly, the installer need to pay attention to radiation effect
to human being through the permitted use distance. The device and the antenna for this device must be
installed to ensure a minimum separation distance of 1.8 meters or more from a person's body. The
maxim service antenna gain should be less than 10dBi.
The installer has to assure by constructive measures or warning labels that general public is not allowed
to get closer to the antenna hen the permitted use distance.
The socket-outlet shall be installed near equipment and shall be easily accessible.
The CE mark sticker can be found on one side of the carton.

1 GENERAL INFORMATION
The mPICO Series Digital Pico Repeater (hereinafter called “mPICO”) is designed for single/dual/triple
band network. It can wireless transmit, bi-directional amplify uplink and downlink signals and is designed
for eliminating communicational coverage blind spots.
mPICO is used in indoor locations where small-scale signal coverage for metropolitan environment is
desired (e.g., hotels, department stores and shopping malls, underground parking lots, convention
centres, arenas, etc.)
Characteristics of mPICO are as follows:
Uplink and downlink with digital carrier selective frequency can efficiently amplify BS signal and MS
signal.
Digital filter technique allows better filter function.
With both gain and frequency temperature automatic adjustment ensures equipment in a stable
operation.
With out-of-band suppression and supports automatic gain temperature compensation function
which can maintain regular operation among working temperature.
Local Operation and Maintenance Terminal (OMT): operating status and parameters can be set or
monitored by OMT locally.
Operation Maintenance Center (OMC): system working parameters and communication
configuration can be set or inquired remotely through the build-in modem. If alarm is generated, the
equipment will dial up to OMC automatically in the mode of SMS or PSD.
External Li-ion battery ensures that alarm information can automatically report to OMC in case of
equipment power failure.
The following figure shows the enclosure of the mPICO.

As shown in the above figure, the downlink BS signals go through DT port to the system and then to
downlink by duplexer separation. The DL signals will go through digital filter. Then the DL signals will be
sent to downlink PA to amplify power and filter via duplexer. After amplification, the signals are
transmitted at the MT port to the service antenna.
On the UL, the signals transmitted by the mobile go through MT integration duplexer and digital filer then
to uplink PA to power amplify and filter via duplexer, finally get back to BS by donor antenna.

3 INSTALLATION
3.1 WARNINGS AND ALERTS
Radio Frequency Energies
There may be situations, particularly for workplace environments near high-powered RF sources, where
recommended limits for safe exposure of human beings to RF energy could be exceeded. In such cases,
restrictive measures or actions may be necessary to ensure the safe use of RF energy.
High Voltage
The equipment has been designed and constructed to prevent, as far as reasonably, practicable danger.
Any work activity on or near equipment involving installation, operation or maintenance must be, as far as
reasonably, free from danger.
Where there is a risk of damage to electrical systems involving adverse weather, extreme temperatures,
wet, corrosive or dirty conditions, flammable or explosive atmospheres, the system must be suitably
installed to prevent danger.
Protective Earthing
Equipment provided for the purpose of protecting individuals from electrical risk must be suitable for the
purpose and properly maintained and used.
Handling Precautions
This covers a range of activities including lifting, lowering, pushing, pulling, carrying, moving, holding or
restraining an object, animal or person. It also covers activities that require the use of force or effort, such
as pulling a lever, or operating power tools.
Electrostatic Discharge (ESD)
Observe standard precautions for handling ESD-sensitive devices. Assume that all solid-state electronic
devices are ESD-sensitive. Ensure the use of a grounded wrist strap or equivalent while working with
ESD-sensitive devices. Transport, store, and handle ESD-sensitive devices in static-safe environments.
Manual Handling
During transportation and installation, take necessary handling precautions to avoid potential physical
injury to the installation personnel and the equipment.

3.2 SITE PLANNING CONSIDERATIONS
Site Considerations
The repeater is designed for indoor installation and operation.
Antenna separation
For optimal operation, the physical separation of the MT and DT antennas should satisfy the condition for
I > GMAX +15dB, where I represents isolation between MT and DT ports.
Environmental
The installation location for the product should be indoor. Also it should have enough room, air flow and
good heat dissipation.
Powering
The power supply unit (PSU) provides power to all modules within the equipment. Depending on the
product variant, it is recommended that the PSU operates on a dedicated circuit breaker or fused circuit.
Grounding Requirement
Verify that the equipment has been well grounded. This includes antennas and all cables connected to
the system. Ensure lightning protection for the antennas is properly grounded.
Cable Routing
The RF cables for mPICO have SMA (F) connectors; other cable connects the equipment with the
external PSU.
Cable requirements are as follow:

3.3 INSTALLATION PROCEDURES
3.3.1 GOODS INWARDS INSPECTION
Verify the number of packages received against the packing list.
Check all packages for external damage; report any external damage to the shipping courier. If there
is damage, a shipping agent should be present before unpacking and inspecting the contents
because damage caused during transit is the responsibility of the agent.
Open and check each package against the packing list. If any items are missing, please contact
Comba.
Do not remove items from antistatic packing until ready for installation. If damage is discovered at
the time of installation, contact the shipping agent.
