For Safety
WARNING
1. ALWAYS refer to the operation manual when working near loca-
tions at which the alert mark shown on the left is attached. If the
operation, etc., is performed without heeding the advice in the
operation manual, there is a risk of personal injury. In addition,
the equipment performance may be reduced.
Moreover, this alert mark is sometimes used with other marks and
descriptions indicating other dangers.
2. Laser radiation warning
• NEVER look directly into the cable connector on the equip-
ment nor into the end of a cable connected to the equipment.
If laser radiation enters the eye, there is a risk of injury.
• Laser Radiation Markings on a following page show the Laser
Safety label attached to the equipment near the cable connec-
tor.
3. When supplying power to this equipment, connect the accessory
3-pin power cord to a 3-pin grounded power outlet. If a grounded
3-pin outlet is not available, before supplying power to the equip-
ment, use a conversion adapter and ground the green wire, or
connect the frame ground on the rear panel of the equipment to
ground. If power is supplied without grounding the equipment,
there is a risk of receiving a severe or fatal electric shock.
4. This equipment cannot be repaired by the user. DO NOT attempt
to open the cabinet or to disassemble internal parts. Only Anritsu-
trained service personnel or staff from your sales representative
with a knowledge of electrical fire and shock hazards should ser-
vice this equipment. There are high-voltage parts in this equip-
ment presenting a risk of severe injury or fatal electric shock to
untrained personnel. In addition, there is a risk of damage to pre-
cision parts.
5. This equipment should be used in the correct position. If the cabi-
net is turned on its side, etc., it will be unstable and may be dam-
aged if it falls over as a result of receiving a slight mechanical
shock.

For Safety
CAUTION
1. Before changing the fuses, ALWAYS remove the power cord from
the poweroutlet and replace the blown fuses. ALWAYS use new
fuses of the type and rating specified on the fuse marking on the
rear panel of the cabinet.
T___A indicates a time-lag fuse.
___A or F___ A indicate a normal fusing type fuse.
There is risk of receiving a fatal electric shock if the fuses are
replaced with the power cord connected.
2. Keep the power supply and cooling fan free of dust.
•Clean the power inlet regularly. If dust accumulates around
the power pins, there is a risk of fire.
•Keep the cooling fan clean so that the ventilation holes are not
obstructed. If the ventilation is obstructed, the cabinet may
overheat and catch fire.

WARNING
This equipment uses parts radiating Class 2 or Class 3 laser radia-
tion. The warning labels shown on the next page are attached near
the laser-radiation locations.
The product name and the danger classification specified by JIS,
IEC825 and 21CFR1040.10 are explained below.
Type JIS, IEC825 21 CFR 1040
MU952501A Class 3A Class III b
MU952502A Class 3A Class III b

MU952604A Class 3A Class III b
MU952605A Class 3A Class III b
MU952606A Class 3A Class III b
Class 1, Class 2 and Class 3 indicates the degree of danger of the
laser radiation outlined below as defined by JIS, IEC825 and
21CFR1040.10.
Class 1 Safe laser presenting no danger when used according to
design specifications.
Class 2 Laser radiating in 400 to 700 nm wavelength range. In
principal, this class of laser is not safe, but the danger to
the eyes is eliminated by the eye avoidance reaction in-
cluding the blink response.
Class 3A Laser radiating in 400 to 700 nm wavelength range. The
danger to the eyes is eliminated by the eye avoidance
reaction including the blink response. For lasers radiat-
ing at other wavelengths, the degree of danger to the na-
ked eyes is not greater than Class 1.
Class 3B The eyes will be damaged if direct laser radiation enters
the eyes. Normally there is no danger if the diffused
beam is observed.

1.1 MT9810A Optical Test Set
The main unit of the MT9810A Optical Test Set (hereafter referred to as the “Device”) forms the core of a group of
optical test set models. It has slots to enable mounting of two plug-in units. The Device is designed to operate units
mounted in the slots and display the status and measured results.
The MT9810A-01 (Option 01) for high power sensor is an option to use the MA9331A/MU931001A Optical-
Sensor/Sensor-Adapter and MU931431A Optical Sensor.
The MT9810A with this Option 01 installed can use all the plug-in units for the MT9810A.
The function, performance, and operation are the same as those of the MT9810A without this Option 01. For those
of the MA9331A/MU931001A Optical-Sensor/Sensor-Adapter and MU931431A Optical Sensor, refer to each the
separate operation manual.
