Safety Precautions
■
Abide by All Safety Requirements
To ensure personal and equipment safety, abide by safety precautions described in the label on equipment or
in the manual when you install, operate, or maintain the equipment. The "Safety Warning", "Caution", and
"Note" in the manual are not the contents of safety requirements. They are provided as the supplement to the
safety precautions.
When operating Huawei products or equipment, strictly follow all precautions and special safety instructions
required by Huawei. The "Safety Warning" in the manual is only based on the knowledge of Huawei. Huawei
will not assume any responsibility for the loss incurred by operations violating the universal safety rules or
standards for designing, producing, or using the equipment.
■
Abide by Local Laws and Regulations
When operating the equipment, abide by local laws and regulations.
■
Requirements for Personnel
The installation and maintenance personnel of Huawei equipment must be strictly trained. They are not allowed
to install, operate, or maintain the equipment until they have mastered the correct operation method and got
familiar with the safety requirements.
Symbol Descr iption
■
Indicates a hazard with a high level of risk, which if not avoided, will result in death or
serious injury.
Indicates a hazard with a medium or low level of risk, which if not avoided, could result
in minor or moderate injury.
Indicates a potentially hazardous situation, which if not avoided, could result in
equipment damage, data loss, performance degradation,
or unexpected results.
Indicates a tip that may help you solve a problem or save time.
Provides additional information to emphasize or supplement important points of the
main text.
Personal Safety
■
• Directly contacting or indirectly contacting high voltage power supply through wet objects is lethally dangerous.
• Incorrect high voltage operations will cause incidents such as fire or a shock hazard.
• Never perform any high voltage AC operations or perform operations on a tower or a mast during a
thunderstorm. It can be lethally dangerous.
• Any equipment must be grounded before it is connected to the power supply. Ungrounded equipment can be
lethally dangerous.
• Never perform any hot-line operation.
• Strong RF signals are harmful to human health. Ensure that the transmit antennas are shut down before an
antenna installation or maintenance operation on a tower or mast installed with multiple transmit antennas.
• During an operation involving optical cables, keep your eyes far away from optical output ports and do not
directly look at the optical output ports with bare eyes.
• Take measures to prevent dusts from entering your respiratory tract or eyes when drilling holes.
• Before connecting cables to storage batteries, disconnect the storage batteries from the power supply.
Otherwise, injuries may be incurred.
• When working aloft, take measures to prevent objects from falling.
Equipment Safety
■
• Before operating the equipment, check the electric continuity of the equipment that requires grounding to
ensure that it is reliably grounded.
• The static electricity produced by human body may damage the static-sensitive components, such as LSI on
boards. Take proper ESD prevention measures, for example, wear ESD wrist straps or gloves to prevent
boards, modules, and electronic components from being destroyed by static of the human body.
• When operating storage batteries, prevent the battery short-circuiting and electrolyte overflow or leakage. The
electrolyte corrodes metal objects and the boards, producing rust and causing board short-circuiting.

z When an external antenna is used,
connect the antenna to the BTS3701B
before installing the BTS3701B.
z When the BTS3701B is installed on a
wall, the integrated mode is
recommended.
z The BTS3701B must be installed at least
0.5 m (1'-7 11/16'') away from the
interference sources such as power
supply and at least 2 m (6'-6 3/4'') away
from the high frequency radiation
sources.
The BTS3701B cannot be placed horizontally
on a flat object, such as a table.
