Introduction
The Natus Photic Stimulator is a powerful, portable option that can enhance and expand
neurologic testing. Driven by the Natus NeuroWorksTM software from laptop or desktop
computers, it supplies intense flashes of light. Its components consist of an arm-mounted light
assembly, a light source, an intensity control, a test button, and a Trigger-in receptacle for a cable
from a headbox. The arm-mount has three adjustment knobs along its length to give the unit
flexibility and versatility.

Warnings and Cautions
Important Safety Information
This equipment/system is intended for use by Healthcare professionals ONLY. Please
read this section before installing any of the hardware. Refer to this section when you
operate, transport, store, or re-install the system.
Make sure that any platform, table, cart, or other surface used during the operation,
transport, or temporary or permanent storage of the system and its components is
adequate, sturdy, and safe. XLTEK is not responsible for any injury or damage that
may result from inadequate, poorly constructed, or unapproved transports, carts, or
operating surfaces.
Never use equipment that has parts missing or equipment that might contain loose
parts inside of it (that is, inside an enclosed portion of the equipment). If you suspect a
piece of equipment has missing or loose parts, contact XLTEK.
Never place powered equipment (that is, equipment that operates with an electric
power source) on any flammable surface. Avoid this whether the equipment is active
or not.
A risk of explosion is possible if you use this device in the presence of flammable
anesthetics.
Reliable grounding requires hospital-grade receptacles and power cord.
Always perform a leakage current test and compare to allowable standards BEFORE
connecting the patient to monitoring equipment
NEVER connect a multiple portable socket outlet to the isolation transformer output
receptacles. Additional cord connected equipment may increase leakage currents and
present a hazard.
XLTEK strongly recommends that you do not open the Photic Device. It contains no
serviceable parts. If you must open the device, disconnect the line cord before you do
so.
Electrostatic Discharge (ESD) Precaution: Be sure to take the
appropriate Electrostatic Discharge (ESD) precautions. Disconnect the
cables before moving, cabling, or performing any set up procedures.
Connectors marked with the ESD protection symbol should not be touched.
This equipment/system may cause radio interference or may disrupt the operation of
nearby equipment. It may be necessary to take mitigation measures, such as
reorienting or relocating the equipment or shielding the location.
Use of cables other than those specified or sold by the manufacturer on the
equipment, may result in increased emissions or decreased immunity of the
equipment and may cause the system to be non-compliant with the requirements of
IEC 60601-1-2:2007

The equipment should not be used adjacent to or stacked with other equipment and
that if adjacent or stacked use is necessary, the equipment should be observed to
verify normal operation in the configuration in which it will be used.
Fast transients precautions (EFT) Precautions: In environments where parasitic
electrical noise interferes with intermittent photic stimulation (IPS) there is no risk of
misinterpretation of EEG waveforms. The visual stimulation is confirmed by the
technologist performing the test. In addition the accompanying EEG
(Electroencephalograph) amplifier’s signals will also be contaminated past the point
where any clinical signal interpretation is possible. Trained electroencephalographic
physicians and technologists are well equipped to identify and disregard signals that
are obscured by environmental noise.
NOTE: XLTEK designates no non-medical equipment for use with the Photic Stimulator
system. No supporting documentation for such devices is necessary.
The Photic Stimulator needs special precautions regarding EMC and needs to be
installed and put into service according to the EMC information provided in this user
manual.
Portable and mobile RF communications equipment can affect the functionality of the
Photic Stimulator.

Installation and Operation
WARNING: Never place the photic device on the floor.
1) Place the photic device on a platform, table, cart, or other raised surface.
Never place the photic device on the floor.
2) Plug the photic device only into a power outlet marked and verified as Hospital Grade.
NOTE: Acceptable ‘Hospital Grade’ power outlets must be labeled as such.
3) On the XLTEK Connex, Brain Monitor, Brain Monitor ICU, EEG32U or EMU40 headbox,
connect the mini-din 6-pin male end of trigger cable (XLTEK part number 003771) to the
Photic connector.
4) On the XLTEK Trex headbox, connect the Hirose connector of trigger cable (XLTEK part
number W6473H) to the Photic connector.
5) On the XLTEK PCI computer-headbox interface card (used with EEG32, EMU40,
EMU128FS, Mobee and Hyppo headboxes), connect the mini-din 4-pin male end of trigger
cable (XLTEK part number 003771) to the matching connector on the PCI card.
