1 Safety Precautions
1.1 Definitions and Symbols
The following terms and symbols are used in this documentation and also
appear on the Models 1936/2936 Series Optical Power Meters where safety-
related issues occur.
1.1.1 General Warning or Caution
Figure 1 General Warning or Caution Symbol
The Exclamation Symbol in the figure above appears in Warning and Caution
tables throughout this document. This symbol designates an area where
personal injury or damage to the equipment is possible.
1.1.2 Electric Shock
Figure 2 Electrical Shock Symbol
The Electrical Shock Symbol in the figure above appears throughout this
manual. This symbol indicates a hazard arising from dangerous voltage.
Any mishandling could result in irreparable damage to the equipment, and
personal injury or death.
1.1.3 Protective Conductor Terminal
Figure 3 Protective Conductor Terminal Symbol
The protective conductor terminal symbol in the above figure identifies the
location of the bonding terminal, which is bonded to conductive accessible
parts of the enclosure for safety purposes.

20 Safety Precautions
1.1.4 European Union CE Mark
Figure 4 CE Mark
The presence of the CE Mark on Newport Corporation equipment means that
it has been designed, tested and certified as complying with all applicable
European Union (CE) regulations and recommendations.
