Safety Summary
FOE-ANZENA00
To ensure thorough understanding of all functions and to ensure efficient use of this instrument, please read the
manual carefully before using. Note that ADC Corporation (hereafter referred to as ADC) bears absolutely no re-
sponsibility for the result of operations caused due to incorrect or inappropriate use of this instrument.
If the equipment is used in a manner not specified by ADC, the protection provided by the equipment may be im-
paired.
• Warning Labels
Warning labels are applied to ADC products in locations where specific dangers exist. Pay care-
ful attention to these labels during handling. Do not remove or tear these labels. If you have any
questions regarding warning labels, please ask your nearest ADC dealer. Our address and phone
number are listed at the end of this manual.
Symbols of those warning labels are shown below together with their meaning.
DANGER: Indicates an imminently hazardous situation which will result in death or serious
personal injury.
WARNING: Indicates a potentially hazardous situation which will result in death or serious
personal injury.
CAUTION: Indicates a potentially hazardous situation which will result in personal injury or
a damage to property including the product.
• Basic Precautions
Please observe the following precautions to prevent fire, burn, electric shock, and personal inju-
ry.
• Use a power cable rated for the voltage in question. Be sure however to use a power cable
conforming to safety standards of your nation when using a product overseas.
• When inserting the plug into the electrical outlet, first turn the power switch OFF and then
insert the plug as far as it will go.
• When removing the plug from the electrical outlet, first turn the power switch OFF and then
pull it out by gripping the plug. Do not pull on the power cable itself. Make sure your hands
are dry at this time.
• Before turning on the power, be sure to check that the supply voltage matches the voltage
requirements of the instrument.
• Connect the power cable to a power outlet that is connected to a protected ground terminal.
Grounding will be defeated if you use an extension cord which does not include a protective
conductor terminal.
• Be sure to use fuses rated for the voltage in question.
• Do not use this instrument with the case open.
• Do not place anything on the product and do not apply excessive pressure to the product. Al-
so, do not place flower pots or other containers containing liquid such as chemicals near this

• When the product has ventilation outlets, do not stick or drop metal or easily flammable ob-
jects into the ventilation outlets.
• When using the product on a cart, fix it with belts to avoid its drop.
• When connecting the product to peripheral equipment, turn the power off.
• Caution Symbols Used Within this Manual
Symbols indicating items requiring caution which are used in this manual are shown below to-
gether with their meaning.
DANGER: Indicates an item where there is a danger of serious personal injury (death or seri-
ous injury).
WARNING: Indicates an item relating to personal safety or health.
CAUTION: Indicates an item relating to possible damage to the product or instrument or relat-
ing to a restriction on operation.
• Safety Marks on the Product
The following safety marks can be found on ADC products.
: ATTENTION - Refer to manual.
: Protective ground (earth) terminal.
: DANGER - High voltage.
: CAUTION - Risk of electric shock.
• Replacing Parts with Limited Life
The following parts used in the instrument are main parts with limited life.
Replace the parts listed below before their expected lifespan has expired to maintain the perfor-
mance and function of the instrument.
Note that the estimated lifespan for the parts listed below may be shortened by factors such as
the environment where the instrument is stored or used, and how often the instrument is used.

Safety Summary
Safety-3
FOE-ANZENA00
Main Parts with Limited Life
• Hard Disk Mounted Products
The operational warnings are listed below.
• Do not move, shock and vibrate the product while the power is turned on.
Reading or writing data in the hard disk unit is performed with the memory disk turning at a
high speed. It is a very delicate process.
• Store and operate the products under the following environmental conditions.
An area with no sudden temperature changes.
An area away from shock or vibrations.
An area free from moisture, dirt, or dust.
An area away from magnets or an instrument which generates a magnetic field.
• Make back-ups of important data.
The data stored in the disk may become damaged if the product is mishandled. The hard disc
has a limited life span which depends on the operational conditions. Note that there is no
guarantee for any loss of data.
• Precautions when Disposing of this Instrument
When disposing of harmful substances, be sure dispose of them properly with abiding by the
state-provided law.
Harmful substances: (1) PCB (polycarbon biphenyl)
(2) Mercury
(3) Ni-Cd (nickel cadmium)
(4) Other
Items possessing cyan, organic phosphorous and hexadic chromium
and items which may leak cadmium or arsenic (excluding lead in sol-
der).
Example: fluorescent tubes, batteries
