Caution notices
A caution notice calls attention to a situation that is potentially hazardous to people
because of some existing condition. A caution notice can be accompanied by
different symbols, as in the examples below:
If the symbol is... It means...
A hazardous electrical condition with less severity than
electrical danger.
A generally hazardous condition not represented by other
safety symbols.
A hazardous condition due to the use of a laser in the
product. Laser symbols are always accompanied by the
classification of the laser as defined by the U. S.
Department of Health and Human Services (for example,
Class I, Class II, and so forth).
Sample caution notices:
CAUTION:
This product is equipped with a 3–wire (two conductors and
ground) power cable and plug. Use this power cable with a properly
grounded electrical outlet to avoid electrical shock.
CAUTION:
Data processing environments can contain equipment transmitting
on system links with laser modules that operate at greater than
Class 1 power levels. For this reason, never look into the end of an
optical fiber cable or open receptacle.
Attention notices
An attention notice indicates the possibility of damage to a program, device, or
system, or to data. An exclamation point symbol may accompany an attention
notice, but is not required. A sample attention notice follows:
Attention: Do not bend a fibre-optic cable to a radius less than 5 cm (2
in.); you can damage the cable. Tie wraps are not recommended for
optical cables because they can be easily overtightened, causing
damage to the cable.
