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 coloured 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.

1 GENERAL INFORMATION
The RA-5300 Tri-band Distributed Antenna System (hereinafter called “RA-5300”) consists of Master Unit
(MU) and Remote Unit (RU). MU is made up of main unit, duplexer unit and optical unit. The system
supports 850MHz, 1800 MHz and 2100 MHz. It‟s advanced monitoring function helps users remotely
monitor and control the device parameter and status inquery through Ethernet, at the same time, users
can also locally configure the device through PC.
The low signal transmission loss of optical fiber is applicable for long distance transmission. RA-5300 can
support the optical transmission of up to 10dB signal transmission loss.
Main feature:
High power bandwidth linear PA ensures signals no distortion amplification.
Optical fiber transmission with long distance transition at the most path loss of 10dB.
Has AGC function, automatic compensates path loss.
Local Operation and Maintenance Terminal (OMT): operating status and parameters can be set or
monitored by OMT PC locally. And the point-to-point setting and inquiry between MU and RU is
realizable through the integrated wireline/wireless modem, which makes it convenient for on-site
configuration.
Operation Maintenance Center (OMC): real time monitor, set and inquire device status information.
Build-in Li-ion battery ensures that alarm information can automatically report to OMC in case of
equipment power failure.
RU is designed for all-weather outdoor operation - waterproof, damp-proof and omni-sealed.
A dimension for MU is shown in table bellowed.
