Safety Information, Instructions, and Symbols
Before Initializing and Operating the Unit
•
Inspect the unit for any signs of damage, and read the user's manual thoroughly.
•
Install the unit as specified in the Getting Started section on page 11.
•
Ensure that the unit and any devices or cords connected to it are properly grounded.
Operating the Unit
Warning
To avoid the risk of injury or death, always observe the following precautions before initial-
izing the unit:
•
If using a voltage-reducing autotransformer to power the unit, ensure that the common
terminal connects to the earthed pole of the power source.
•
Do not interrupt the protective earth grounding. Any such action can lead to a poten-
tial shock hazard that can result in serious personal injury. If an interruption to the pro-
tective grounding is suspected, ensure that the unit remains inoperative.
•
Never look into the end of an optical cable connected to an optical output device that
is operating. Laser radiation is invisible, and direct exposure can severely injure the
human eye. For more information, see the user's manual of the laser source in use.
•
Turning off the power to the device does not always block the externally supplied radi-
ation to the connector at the output of the unit.
•
Do not use the unit outdoors.
•
To prevent potential fire or shock hazard, do not expose the unit to any source of
excessive moisture.
•
Do not operate the unit when its covers or panels have been removed.
•
Unless absolutely necessary, do not attempt to adjust or perform any maintenance or
repair procedure when the unit is opened and connected to a power source.
•
Repairs are to be carried out only by a qualified professional.
•
Do not attempt any adjustment, maintenance, or repair procedure to the unit's internal
mechanism if immediate first aid is not accessible.
•
Disconnect the power from the unit before adding or removing any components.
•
Operating the unit in the presence of flammable gases or fumes is extremely hazard-
ous.
•
Do not perform any operating or maintenance procedure that is not described in the
user's manual.
•
Some of the unit's capacitors can be charged even when the unit is not connected to
the power source.
