BEFORE USE, READ THIS MANUAL.
Operation and maintenance of the instrument are under the administrative
responsibility of the user.
The cautions for safety and operating procedures must be thoroughly understood before
using the instrument.
Keep this manual handy for reference.
In this manual, a signal word is used to designate the degree or level of safety alert-
ing. The definition is as follows.

CAUTIONS: Usage Precautions
1.3 Usage Precautions
Before use
CAUTION
• Do not use the instrument for any purposes other than the intended purpose.
NIDEK is not responsible for accidents or malfunctions caused by misuse.
For the intended purpose of the instrument, see “2.1 Outline of the Instrument” (page 8).
• Only personnel authorized by NIDEK or a NIDEK distributor are allowed to install the instrument.
• Install the instrument in an environment that meets the following conditions. The following conditions
must be maintained during use.
•Use conditions
Temperature: 5 to 40°C (41 to 104°F)
Humidity: 30 to 80% (5 to 31°C)(41 to 87.8°F) The minimum acceptable relative humidity is 30%. The
maximum acceptable relative humidity is 80% for temperatures up to 31°C (87.8°F) which decreases
linearly to 50% at 40°C (104°F).
Altitude: Up to 2,000 m
Installation location: Interior (with low dust and free from smoke, vibration, and impact)
• Be sure to wear protective gloves when using a utility knife during unpacking.
Contact by bare hands with a utility knife or sharp edge of cardboard may result in injury.
• Install the instrument on a table with a height and depth that allows comfortable operation.
Continued use in an awkward posture may result in backache.
• Avoid storing the instrument where it is exposed to rain or water, or toxic gas or liquid is present.
Corrosion or malfunction may occur.
• Hold the unit by the base with both hands when moving the instrument.
Failure to do so may cause the instrument to drop resulting in injury or malfunction.
• Before connecting the cable, turn off the power switch and disconnect the power cord from the wall
outlet.
Electric shock or malfunction may result.
• Do not use the power cord other than those supplied. Also do not connect the supplied cord to any
other instrument.
Malfunction or fire may result.
• Do not overload the electrical outlet.
A multi-outlet supplying power to too many instruments may become overheated and cause fire.
• Install the instrument in area where the outlet that the power plug is inserted into is easily accessible
during use. In addition, ensure that the power cord can be disconnected without the use of any tool.
Otherwise, it may interfere with disconnecting of the power from the input power source in case of
abnormality.
• Be sure to use a wall outlet which meets the power specification requirements.
If the line voltage is too high or too low, the instrument may not perform properly. Malfunction or fire
may result.
• Completely insert the power plug into a grounded outlet as far as the prongs will go.
Electric shock or fire may result in the event of malfunction or power leakage.
• Do not place heavy objects on the power cord.
The damaged power cord may cause fire or electric shock.

During use
After use
CAUTION
• Only personnel authorized by NIDEK or a NIDEK distributor are allowed to disassemble or touch the
interior of the instrument.
Electric shock or malfunction may result.
• In the event of smoke or strange odors, immediately turn off the instrument and disconnect the
power plug from the wall outlet. Once it is confirmed that the smoke has stopped, contact NIDEK or
your authorized distributor.
Usage of the instrument under such abnormal conditions may cause fire or electric shock. In case of
fire, use a dry chemical (ABC) extinguisher to extinguish the fire.
• Immediately replace the power cord if the internal wires are exposed, power is intermittent when the
power cord is moved, or the cord and/or plug are hot to the touch.
This may result in electric shock or fire.
CAUTION
• Do not pull the power cord to disconnect it from the wall outlet. Always hold it by the plug.
This can damage the metal core of the cord and may result in fire, short circuit or electric shock.
• Occasionally clean the prongs of the power plug with a dry cloth.
If dust settles between the prongs, the dust will collect moisture, and short circuit or fire may occur.
• If the instrument is not to be used for a long time, disconnect the power cord from the wall outlet.
Fire may result.
• Maintain the surrounding temperature and humidity at the following ranges during transport and
storage of the instrument.
Environmental conditions
Temperature: −20 to 70°C (−13 to 158°F)
Humidity: 10 to 85% (Non-condensing)
Transport handling: Prevent leakage, keep right side up, and handle with care. Only stack up to the
specified number of units.
• When transporting the instrument, use the special packing materials to protect the instrument from
shock or impact. Excessive vibration or impact to the instrument may cause malfunction.

CAUTIONS: Usage Precautions
Maintenance
CAUTION
• Be sure to check before use and after use. It is recommended to have regular maintenance checks
every two years.
Regular checks must be performed by qualified personnel. Ask NIDEK or your authorized distributor
for details.
• When performing maintenance work, secure a sufficient maintenance space.
Maintenance work in an insufficient space may result in injury.
• Use the specified fuses to replace the old ones.
Use of any fuses other than those specified may result in fire.
• Before fuse replacement, turn off the instrument and disconnect the power cord from the wall outlet.
Electric shock may result.

Disposal
Other cautions
CAUTION
• Follow the local ordinances and recycling regulations regarding disposal or recycling of the compo-
nents.
It is recommended to commission the disposal to a designated industrial waste disposal contractor.
Inappropriate disposal may contaminate the environment.
• When disposing of packing materials, sort them by material and follow local ordinances and recy-
cling regulations.
Inappropriate disposal may contaminate the environment.
• Connect the cable to the RS-232C connector or USB connector securely, maintaining the correct
orientation of the cable connector. Data transmission is not performed properly.
• Be sure not to apply excessive pressure to the stylus of the tracer. The stylus is easy to bend or
break.
• When the instrument is not in use, turn off the power switch and put the dust cover on.
If dust accumulates, it may affect the measurement accuracy or result malfunction.
• Never use organic solvents such as a paint thinner to clean the exterior of the instrument. It may ruin
the surface of the instrument.

INTRODUCTION: Outline of the Instrument
2.1 Outline of the Instrument
The NIDEK Satellite Tracer Model LT-980 is a frame tracer which measures the shape*1 of spectacle
frames (hereafter referred to as frames).
It traces the shape of frames in three dimensions to measure the three-dimensional lens circumfer-
ence*2. In addition, measurement of patterns or demo lenses is available.
The instrument is very easy to use simply by setting frames or such and pressing a button.
This instrument can be connected to various kinds of lens edging equipment to comprise a lens pro-
cessing system.*3
*1. Shape refers to the outer circumference of spectacle lenses or the inner circumference of spectacle frame rims.
*2. Frame groove is taken to be the length of a single straight line.
*3. The LT-980 interface specifications must be compatible with the connecting systems.
• Standard specifications → Connecting to a personal computer or NIDEK’s grinding system
• LAB specifications →Connecting to a LAB system
• The references to right and left in this operator’s
manual are those viewed from the rear as
