Safety & Certification Notice
“Only qualified personnel should handle the DAS equipment. Any person involved in the installation or service of the DAS should understand and follow these safety guidelines.”
-
Obey all general and regional installation and safety regulations relating to work on high voltage installations, as well as regulations covering the correct use of tools and personal protective equipment.
-
The power supply unit in repeaters contains dangerous voltage levels, which can cause electric shock. Switch the mains off prior to any work in such a repeater. Any local regulations are to be followed when servicing repeaters.
-
eROU equipment is exclusive to the indoors.
-
Use this unit only for the purpose specified by the manufacturer. Do not carry out any modifications or fit any spare parts which are not sold or recommended by the manufacturer. This could cause fires, electric shock, or other injuries.
-
Any DAS system or Fiber BDA will generate radio (RF) signals and continuously emit RF energy. Avoid prolonged exposure to the antennas. SOLiD recommends maintaining a 40 cm minimum clearance from the antenna while the system is operating.
-
Do not operate this unit on or close to flammable materials, as the unit may reach high temperatures due to power dissipation.
-
Do not use any solvents, chemicals, or cleaning solutions containing alcohol, ammonia, or abrasives on the DAS equipment. Alcohol may be used to clean fiber optic cabling ends and connectors.
-
To prevent electrical shock, switch the main power supply off prior to working with the DAS System or Fiber BDA. Never install or use electrical equipment in a wet location or during a lightning storm.
-
Do not look into the ends of an optical fiber or directly into the optical transceiver of any digital unit. Use an optical spectrum analyzer to verify active fibers. Place a protective cap over any radiating transceiver or optical fiber connector to avoid the potential of radiation exposure.
-
Allow sufficient fiber length to permit routing without severe bends. – For pluggable equipment, make sure to install the socket outlet near the equipment so that it is easily accessible.
-
A readily accessible disconnect device shall be incorporated external to the equipment.
-
This power of this system shall be supplied through wiring installed in a normal building.
If powered directly from the mains distribution system, it shall be used as additional protection, such as an overvoltage protection device -
Only 50 ohm rated antennas, cables, and passive equipment shall be used with this remote. Any equipment attached to this device not meeting this standard may cause degradation and unwanted signals in the bi-directional system. All components connected to this device must operate in the frequency range of this device.
-
Only 50 ohm rated antennas, cables, and passive components operating from 150 – 3 GHz shall be used with this device.
-
The head-end unit must always be connected to the Base Station using a direct cabled connection. This system has not been approved for use with a wireless connection via server antenna to the base station.
-
Access can only be gained by SERVICE PERSONS or by USERS who have been instructed about the reasons for the restrictions applied to the location and about any precautions that shall be taken; and
-
Access is through the use of a TOOL or lock and key, or other means of security, and is on trolled by the authority responsible for the location.
-
Notice! Be careful not to touch the Heat-sink part due to the high temperature.
-
Signal booster warning label message should include
Part 90 and Part 20 Signal Boosters| THIS IS A 90.219. CLASS B DEVICE

System configuration and Functions
2.1 eROU(edge Remote Optic Unit)
eROU receives TX optical signals from eHUB and converts them into RF signals.
The converted RF signal is radiated to the antenna port via the AMP and
Multiplexer.
When receiving RX signals through the antenna port, this unit filters out-of-
band signals in a corresponding Multiplexer and sends the results to OPTIC to
make electronic-optical conversion of them.
After converted, the signals are sent to an upper device of eHUB.
The eROU supports up to 4 bands.
In addition, if band extension is required, another eROU can be added up to
three using optical splitters and RF ports. However, the band expansion
equipment will be developed in the future.
And eROU is divided into an Internal product with an antenna and an External
product without an antenna.

FCC Statement
RF Radiation Exposure
This equipment complies with RF radiation exposure limits set forth for an
uncontrolled environment. This equipment should be installed and operated with
a minimum distance of 40 cm between the radiator and your body. This
transmitter must not be co-located or operating in conjunction with any other
antenna or transmitter. RF exposure will be addressed at the time of
installation and the use of higher gain antennas may require larger separation
distances.
FCC Part 15.105 statement
This equipment has been tested and found to comply with the limits for a Class
A digital device, pursuant to part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against harmful interference when
the equipment is operated in a commercial environment. This equipment
generates, uses, and can radiate radio frequency energy and, if not installed
and used in accordance with the instruction manual, may cause harmful
interference to radio communications. Operation of this equipment in a
residential area is likely to cause harmful interference in which case the
user will be required to correct the interference at his own expense.
FCC Part 15.21 statement
Any changes or modifications not expressly approved by the party responsible
for compliance could void the user’s authority to operate this equipment.
For external & Internal antenna type, the following antenna gain must be
applied.
