Term Explanation
Duplexer is a device that allows bi-directional communication. Its role is to isolate the TX signal from
the RX signal to ensure that the transmitter and receiver can work normally. It consists of two groups of
band-stop filters with different frequencies, to prevent it from transmitting the signals to the receiver.
Feed Line is the cable or transmission line that connects the antenna with the radio transmitter or
receiver.
Voltage Standing Wave Ratio (VSWR) is a value that measures how well a load is
impedance-matched to a source.
Squelch is a circuit function that acts to suppress the audio output of a receiver in the absence of a
sufficiently strong desired input signal.

6
3.2.2 Before Installation
Voltage Check
Please check whether the voltage of DC power or battery meets the repeater specifications (28V±15%).
Product Check
Please check whether the repeater works properly by observing the eight LEDs located in the front
panel.
Parameter Configuration
Having confirmed that the repeater works properly, you can let your dealer configure the parameters for
the repeater based on your actual needs (such as Frequency Range, TX Power, etc.), and then you can
proceed with on-site installation.
3.2.3 Installation Procedures
Follow the steps to install the repeater:
1. Install the repeater at a proper location;
2. Connect accessories such as the antenna, feed line and power cord to the repeater.
3. Ground the repeater through the ground screw located on the rear panel.
3.3 Installing the Duplexer (Optional)
If the repeater needs to work with a duplexer, you should implement the following operations before
installation.
1. Loosen the three screws on the bracket with a crosshead screwdriver. See the following figure:
2. Install the duplexer onto the bracket.

7
Be sure to observe the specifications of the two antenna interfaces on the duplexer, to determine
which one should be connected to the transmitter. The interface connecting the transmitter should be
close to PA module to reduce RF loss. See the following figure:
3. Loosen the screws at the back of the top cover, and then pull the top cover backwards to remove it.
See the following figure:
4. Loosen the six screws locking the PA heat sink, remove all power, data and RF cables from the PA,
and finally remove the PA heat sink. See the following figure:
5. Connect the RF cable. See the following figure:

8
6. Install the duplexer to the repeater.
Mount the duplexer properly on the exciter module and receiver module, and then fasten it with the
two screws inside the housing and on the side respectively.
7. Attach the PA heat sink and connect all PA power, data and RF cables to it.
8. Close the repeater top cover and the installation is complete.

3.4 After-installation Check
After installation is completed, power on the product and check whether it works properly by observing
the eight LEDs and the LED segment display located in the front panel.

You may customize repeater parameters such as TX/RX frequency, TX power and
signalling, according to user needs. After configuration of parameters is complete, you
may perform site installation.
Installation Requirements
1. Environmental Conditions at Intended Installation Site
The repeater may be installed in any location suitable for electronic communication
equipment, provided that the environmental conditions do not exceed the equipment
specifications for temperature, humidity and air quality.
Operating Temperature
-30℃to +60℃
This is the temperature measured in close proximity to the repeater. For example, if the
repeater is mounted in a cabinet, the temperature within the cabinet is measured.
Humidity
Humidity conditions should not exceed 95% relative humidity @ 50°C.
Air Quality
For equipment operating in an area which is environmentally controlled and with the
repeater rack mounted, the airborne particle level must not exceed 25μg/m3.
And for equipment operating in an area which is not environmentally controlled and with
the repeater cabinet mounted, the airborne particle level must not exceed 90μg/m3.
Caution: If the repeater is to be installed in an area which is usually dusty, dirty, or
does not meet the air quality requirements, then the air used to cool the repeater modules
must be treated using appropriate filtering devices. Dust or dirt accumulated on the
internal circuit boards and modules is not easily removed, and can cause malfunctions
such as overheating and intermittent electrical connections.
2. Equipment Ventilation
The PA heatsink is equipped with a cooling fan used to provide forced convection cooling.
When planning the installation, observe the following ventilation guidelines:
Customer supplied cabinets must be equipped with ventilation slots or openings for

9
air to enter and exit. If several repeaters are installed in a single cabinet, ensure
ventilation openings surrounding each repeater allow for adequate cooling.
All cabinets must have at least 10cm of open space between the air vents and any
wall or other objects.
When multiple cabinets (each equipped with several repeaters) are installed in an
enclosed area, ensure appropriate ventilation and consider air conditioning or other
climate control equipment, to satisfy the temperature requirements stated above.
3. Equipment Installation Methods
The CHU-P1BA01 may be mounted in a rack, bracket or cabinet, and may be placed on
your desk.
4. Site Grounding and Lightning Protection
Caution: Proper site grounding and lightning protection are vitally important
considerations. Failure to provide proper lightning protection may result in permanent
damage to the repeater.
The ground and lightning protection system is one of the most important considerations
when designing a communication site. Proper grounding techniques and lightning
protection are closely related, and the general category of site grounding may be divided
into the following two sections:
Electrical Ground
Ground wires carrying electrical current from circuitry or equipment at the site are included
in the category of electrical ground. Examples include the AC and DC power used to
source equipment located at the site, and wires or cables connected to alarms or sensors
located at the site.
Lightning Ground
Providing adequate lightning protection is critical to a safe reliable communication site.
The repeater is equipped with a ground screw located on the rear panel. This screw is
used to connect the repeater to the site grounding. All antenna cables, and AC and DC
power cords, should be properly grounded and lightning protected by following the rules
and guidelines provided in the above sections.

13
Electrical Connections
After the repeater has been mechanically installed, electrical connections must be made.
This involves making the following connections:
DC power cord
Antenna cables
See the rear panel view for the positions of connectors.
Power Supply Connections
1. Ground
Connection
The repeater is equipped with a ground screw located on the rear panel. Connect ground
wires to the screw.
2. DC Power Supply or Battery Backup Connection

14
The repeater may be connected to a regulated DC power supply or a backup battery.
The DC source or battery backup system is connected to the repeater through the DC
power inlet at the rear of the repeater (see rear panel view).
Caution: Before you make the connection, ensure the DC power supply or battery
backup system is capable of supplying a minimum of 200W, and check if the DC power
supply has current limit. Since high current consumption is required for transmitting,
improper setting of the current limit may cause transmission failure.
Caution: The repeater is to be connected to a battery that is in accordance with
applicable electrical regulations for the end use country. If battery power is exhausted, you
are recommended to charge the battery with an external charger. Remove the battery
from the repeater when charging.
RF Antenna Connections
TX and RX antennas are connected to two separate connectors (shown in the rear panel
view), and there must be adequate isolation of 75 dB UHF or 85 dB VHF between them. If
only one antenna through a duplexer is connected, at least 75 dB UHF or 85 dB VHF
isolation between the TX and RX antenna ports is required.
Caution: Please ensure that all power is switched off before disconnecting the TX
antenna.
1. Duplexer Selection
The selection of duplexer is critical to system performance. The use of a notch (band
reject) duplexer is possible in some systems that are not located at high RF density sites.
If the repeater is used in high RF density sites, the use of a pass-notch duplexer is
recommended.
The duplexer must be able to handle at least 50W continuously. For the best system
performance, the insertion loss should be less than 2dB.
