CAUTION!
CAUTION
Do not operate the TruNarc analyzer if the laser aperture is cracked. When the
laser aperture is cracked, the instrument’s laser beam is collimated rather than
divergent, and the laser is no longer safe to operate under any circumstances.
The laser aperture is most likely to crack when you drop the instrument. To
check for cracks, turn the instrument off, remove the nose cone, and check the
integrity of the laser aperture. If the laser aperture is cracked, take the
instrument out of service and contact Thermo Fisher Scientific Customer
Support.
CAUTION
There are no user-serviceable components inside the TruNarc analyzer. The
connector compartment door may be opened, but do not open the protective
enclosure or modify the electronics within. All service operations must be
performed by Thermo Fisher Scientific or an authorized service agent of Thermo
Fisher Scientific. Any attempt by the user to open the TruNarc analyzer will
render the warranty null and void.
CAUTION
WARNING: Use of controls, adjustments, or performance of procedures other
than those specified herein or those specified by the manufacturer's personnel
may result in a hazardous condition.
CAUTION
Follow your organization's procedure and regulations for the handling of
unknown substances. WARNING: Scanning a thermally sensitive material
contained in a tightly sealed vessel (e.g., capped jar or vial) with the TruNarc
analyzer may cause a pressure build up and subsequent explosion of the
vessel.
