Safety Summary
The following general safety precautions must be observed during
all phases of operation, service, and repair of this instrument.
Failure to comply with these precautions or with specific warnings
elsewhere in this manual violates safety standards of design,
manufacture, and intended use of the instrument. Hewlett-Packard
Company assumes no liability for the customer’s failure to comply
with these requirements.
General This is a Safety Class 1 instrument (provided with
terminal for protective earthing) and has been manufactured and
tested according to international safety standards.
Operation – Before applying power Comply with the
installation section. Additionally, the following shall be observed:
• Do not remove instrument covers when operating.
• Before the instrument is switched on, all protective earth
terminals, extension cords, auto-transformers and devices
connected to it should be connected to a protective earth via a
ground socket. Any interruption of the protective earth
grounding will cause a potential shock hazard that could result
in serious personal injury.
• Whenever it is likely that the protection has been impaired, the
instrument must be made inoperative and be secured against any
unintended operation.
• Make sure that only fuses with the required rated current and of
the specified type (normal blow, time delay, etc.) are used for
replacement. The use of repaired fuses and the short-circuiting
of fuseholders must be avoided.
• Adjustments described in the manual are performed with power
supplied to the instrument while protective covers are removed.
Be aware that energy at many points may, if contacted, result in
personal injury.
• Any adjustments, maintenance, and repair of the opened
instrument under voltage should be avoided as much as possible,
and when unavoidable, should be carried out only by a skilled
person who is aware of the hazard involved. Do not attempt
internal service or adjustment unless another person, capable of
rendering first aid and resuscitation is present. Do not replace
components with power cable connected.

Safety Summary
• Do not operate the instrument in the presence of flammable
gases or fumes. Operation of any electrical instrument in such an
environment constitutes a definite safety hazard.
• Do not install substitute parts or perform any unauthorized
modification to the instrument.
• Be aware that capacitors inside the instrument may still be
charged even if the instrument has been disconnected from its
source of supply.
Safety Symbols
The apparatus will be marked with this symbol when it is necessary
for the user to refer to the instruction manual in order to protect the
apparatus against damage.
Caution, risk of electric shock.
Frame or chassis terminal.
Protective conductor terminal.
Hazardous laser radiation.
Electromagnetic interference (EMI)
WARNING TheWARNING sign denotes a hazard. It calls attention to a procedure,
practice or the like, which, if not correctly performed or adhered to,
could result in injury or loss of life. Do not proceed beyond a
WARNING sign until the indicated conditions are fully understood and
met.
CAUTION The CAUTION sign denotes a hazard. It calls attention to an operating
procedure, practice or the like, which, if not correctly performed or adhered
to, could result in damage to or destruction of part or all of the equipment.
Do not proceed beyond a CAUTION sign until the indicated conditions are
fully understood and met.

Safety Summary
A sheet of laser safety warning labels is included with the laser module. You
must stick the labels in the local language onto the outside of the instrument,
in a position where they are clearly visible to anyone using the instrument.
NOTE The Max. Output Power stated on the label located on the rear panel of the
instrument are the maximum allowances for class 1 (USA) and class 3A
(non-USA) laser products respectively.
The real output power of the built-in laser source(s) never exceeds 500 µW.
The recommended position for the laser safety warning label is the
bottom right corner on the front of the instrument as shown by the
arrow in the diagram below.
You must return instruments with malfunctioning laser modules to
a HP Service Center for repair and calibration, or have the repair
and calibration performed on-site by HP personnel.
The laser module has built in safety circuitry that disables the
optical output in the case of a fault condition.
WARNING Use of controls or adjustments or performance of procedures other
than those specified for the laser source may result in hazardous
radiation exposure.
WARNING Refer Servicing only to qualified and authorized personnel.
WARNING Do not enable the laser when there is no fiber attached to the optical
output connector.
The optical output connector is at the bottom right corner of the

Safety Summary
instrument’s front panel.
The laser is enabled by pressing SOURCE ON/OFF. The laser is enabled
when the green LED on the front panel of the laser module is lit.
WARNING Under no circumstances look into the end of an optical cable attached
to the optical output when the device is operational.
The laser radiation is not visible to the human eye, but it can seriously
damage your eyesight.
There is a safety circuit which monitors the average laser power
output, and the power output of each laser pulse. If either the
average or the pulse power is greater than the limit for the module,
the laser will be disabled.
