WARNING
●ALWAYS refer to the operation manual when working near locations
at which the alert mark shown on the left is attached. If the advice in
the operation manual is not followed, there is a risk of personal injury
or reduced equipment performance. The alert mark shown on the left
may also be used with other marks and descriptions to indicate other
dangers.
●Overvoltage Category
This equipment complies with overvoltage category II defined in IEC
61010. DO NOT connect this equipment to the power supply of
overvoltage category III or IV.
●Laser radiation warning
- NEVER look directly into the cable connector on the equipment
nor into the end of a cable connected to the equipment. There is a
risk of injury if laser radiation enters the eye.
- The Laser Safety label is attached to the equipment for safety use
as indicated in "Laser Safety" later in this section.
●Only qualified service personnel with a knowledge of electrical fire and
shock hazards should service this equipment. This equipment cannot
be repaired by the operator. DO NOT attempt to remove the equipment
covers or unit covers or to disassemble internal components. There are
high-voltage parts in this equipment presenting a risk of severe injury
or fatal electric shock to untrained personnel. In addition, there is a risk
of damage to precision components.
●The performance-guarantee seal verifies the integrity of the equipment.
To ensure the continued integrity of the equipment, only Anritsu service
personnel, or service personnel of an Anritsu sales representative,
should break this seal to repair or calibrate the equipment. Be careful
not to break the seal by opening the equipment or unit covers. If the

WARNING
●This equipment should always be positioned in the correct manner. If
the cabinet is turned on its side, etc., it will be unstable and may be
damaged if it falls over as a result of receiving a slight mechanical
shock.
Always set up the equipment in a position where the power switch
can be reached without difficulty.
CAUTION
The OTDR Module outputs high-power optical pulses. Disconnect the
communication equipments from the optical fibers before a
measurement, or the optical sensor of the equipment may be broken.
This equipment is designed for an industrial environment.
In a residential environment, this equipment may cause radio
interference in which case the user may be required to take adequate
measures.
