CAUTION
This product complies with Overvoltage Category II and Pollution Degree
2. It has been designed for indoor use only.
CAUTION
Always use the three-prong AC power cord supplied with this
instrument. Failure to ensure adequate earth grounding by not using this
cord may cause instrument damage.
CAUTION
This instrument has auto-ranging line voltage input. Be sure the supply
voltage is within the specified range.
CAUTION
Use of controls or adjustment or performance of procedures other than
those specified herein may result in hazardous radiation exposure.
CAUTION
This Multi-Wavelength Meter uses a specially designed Windows
application program (Windows ® is a U.S. registered trademark of
Microsoft Corp.) All Multi-Wavelength Meter functionality is directly
available from within the Multi- Wavelength Meter application. Windows
configuration changes made outside of the Multi-Wavelength Meter
application may not work correctly and could cause the instrument to
become inoperable. Do not try to access or make changes to the
Windows Operating system. Repairs caused by the improper use of the
Multi-Wavelength Meter will not be covered under warranty.

There is no output laser aperture
The Keysight 86120D and 86122C do not have an output laser aperture.
However, light less than 1 nW escapes out of the front- panel OPTICAL
INPUT connector. Operator maintenance or precautions are not necessary
to maintain safety. No controls, adjustments, or performance of
procedures result in hazardous radiation exposure.
Laser Safety Information
The laser sources contained in the product specified by this user guide are
classified according to IEC 60825- 1 (2014).
The laser sources comply with 21 CFR 1040.10 except for deviations
pursuant to Laser Notice No. 50 dated 2007- June- 24.
CAUTION
VENTILATION REQUIREMENTS: When installing the product in a cabinet,
the convection into and out of the product must not be restricted. The
ambient temperature (outside the cabinet) must be less than the
maximum operating temperature of the product by 4° C for every 100
watts dissipated in the cabinet. If the total power dissipated in the
cabinet is greater than 800 watts, then forced convection must be used.
CAUTION
Install the instrument so that the detachable power cord is readily
identifiable and is easily reached by the operator. The detachable power
cord is the instrument disconnecting device. It disconnects the mains
circuit from the mains supply before other parts of the instrument. The
front panel switch is only a standby switch and is not a LINE switch.
Alternatively, an externally installed switch or circuit breaker (which is
readily identifiable and is easily reached by the operator) may be used as
a disconnecting device.
