CLINICAL VIGNETTE An 18-year-old woman with medically intractable seizures An 18-year-old woman presented for evaluation of seizures that were not controlled by medical therapy. At the age of 6 months she was hospitalized with a fever and seizures, and was reported to have encephalitis. She lost motor and language developmental milestones, but these were gradually regained and she was treated for a year with phenobarbital and was without recurrent seizures. The phenobarbital was tapered at age 2 but at the age of 6 years she again experienced seizures, which occurred at low frequency until puberty, when the seizure frequency increased to two to three per day. The seizures were characterized by an initial aura of tightness in the head and chest and sweaty palms, followed by impaired consciousness, lip smacking, hand rubbing, and unresponsiveness. During a seizure she was unable to talk but could hear, and could not fully process information. She was treated with a variety of anticonvulsants, including phenobarbital, carbamazepine, phenytoin, valproate, and lamotrigine without significant success in seizure control. Her medical history was otherwise unremarkable. There was no family history of seizures. Physical Examination: Vital signs: normal. Bedside mental status examination: no significant abnormalities. Neuropsychological testing: full-scale IQ of 97, performance IQ of 97 and a verbal IQ of 96; mild difficulty acquiring certain types of information and some difficulty with uncued recall. Speech: normal. Cranial nerves: normal with only minimal, unsustained nystagmus on lateral gaze. Motor and sensory examinations: normal. Muscle stretch reflexes: normal. Coordination and gait: normal. Stop and Consider: What is the classification of her seizures according to the International Classification of Seizures? How should she be treated at this point? Laboratory Findings: CBC, serum chemistries with liver and renal functions, PT, PTT, ESR: normal. MRI: see figure, shows left hippocampal atrophy and increased T2 signal. Interictal EEG: left temporal sharp and slow wave activity suggestive of left temporal onset of seizures. Continuous video-EEG monitoring: several seizures captured. EEG, see figure, next page, shows left mesial temporal (EFO) onset. Interictal positron emission tomography (PET) scan: hypometabolism of the left temporal lobe. Diagnosis: Medically intractable partial complex seizures associated with hippocampal atrophy.

Equipment set up
Step 1) Fully charge the battery before using the NiteSite.
Step 2) Fix the LCD Screen and illuminator module to the scope. (Fig:3)
I) Check the size of the scope tube and select the appropriate clamp from the
NiteSite kit. (1 inch or 30mm)
II) Remove the fixing bolt and knob from the clamp. Open up the clamp and
slide over the scope tube. Then replace the fixing bolt and knob leaving loose.
III) Slide the LCD Screen illuminator module into the clamp "T" slot then tighten
the knob until the LCD screen and illuminator module is secure. Check that
the LCD screen is facing the eye piece. (fig: 2)
IV) Do not over tighten the clamp as this may cause strain damage to the clamp.
Step 3) Select a rubber sleeve to suit your scope, and place onto the scope eye piece. Push
the camera module into the end of the sleeve.
Step 4) Connect the power supply cable and the LCD screen & illuminator module into
back of the camera module. (fig: 4) I) Plug the LCD screen & illuminator module connecting cable into the socket
on the rear of the camera module (NS socket)
II) Connect the DC power cable to the centre socket on the rear of the
Step 5) Turn selector switch to the first position located on top of the LCD screen &

Step 6) The NS50 and NS200 camera modules will require adjustment prior to use. This
will guarantee that the scope reticule is perfectly in focus when viewed on the LCD screen (fig: 8). The focal distance is factory set to 400mm which covers most scopes focal length. This will allow focus to be achieved within a couple of turns anticlockwise. After following steps 1- 5.
I) With the LCD screen in the on position, by turning the intensity switch to
position 1 shown on page 7. (fig: 9) Check that the scope reticule is in focus. If
adjustment is required remove the camera from the sleeve. (fig: 7)
II) Turn the lens 1/4 turn anticlockwise with your index finger. (fig: 6) Place the
camera back into the sleeve. Check that the reticule on the LCD screen is in focus.
If not repeat this process until focus is achieved. (fig: 8)
Once focus of the reticule is complete the NiteSite equipment is ready for use. Should the NiteSite equipment be used on a different rifle and scope then re-focusing may be required.
The NiteSite product must be used adopting a "heads up" shooting position. Please
ensure the camera module, when fitted to the scope, is clear of the facial area as the
recoil on some rifles may result in the camera module impacting the face.
Focusing the camera module will be achieved within two or three anticlockwise revolutions
of the lens. Continuing to turn the lens more than 10 full revolutions anticlockwise will result
in the lens coming out from the lens mount and can be difficult to replace .
The anti-recoil clamp will prevent the LCD screen & illuminator module from sliding out of
the clamp ‘T' slot through recoil. Once the scope clamp is fitted, place the anti-recoil clamp
over the scope clamp. Put the scope clamp bolt in place, passing it through the anti-recoil
clamp slot. Place the LCD screen and illuminator fixing keyway, into the scope clamp ‘T' slot
(fig: 13). Once in place slide the anti-recoil clamp upwards to cover the ‘T' slot (fig 12). Once
in place tighten the scope clamp nut until secure. Do not over tighten!
Push up into place to cover the ‘T' slot Anti-recoil clamp correctly positioned covering the ‘T' slot Operating instructions
Now that the NiteSite equipment is ready for use turn the LCD screen on/off and illuminator
intensity, switch located on the top of the LCD screen & illuminator module, to position 1
(fig 9, 10 & 2)
This is for daylight use. In this position there is no infra-red illumination emitted from the
infra-red illuminator module.
By turning the intensity switch to position 2, will turn on the infra-red illuminator module to
the lowest infra-red intensity setting. This is recommended for night vision use. The infra-
red intensity settings are increased through positions 3, 4, and maximum at position 5. The
LCD screen will switch off briefly between infra-red intensity settings as the power to the
screen is interrupted between the switch operations. (Up to 2 seconds)
LCD screen on/off and illuminator intensity switch settings
LCD screen on and
infra-red illuminator low
LCD screen on and LCD screen on and LCD screen on and infra-red infra-red illuminator medium
infra-red illuminator high
illuminator maximum Note
The NiteSite camera module is always on when the DC power lead is connected. The DC
power lead should be unplugged from the camera module when the NiteSite equipment is
not in use. Failure to do so will continue to discharge the battery even with the intensity
switch in the off position.
LCD screen glare
If during use you find the LCD screen glare too bright, adjust the intensity switch to a lower
setting. This will reduce glare considerably when using the equipment at closer ranges.
Alternatively use the LCD screen anti-glare filters to reduce glare. A pack of 5 filters are
included in the NiteSite kit which can be placed on the LCD screen to suit you.
Flare is the term used to describe a plume or a haze that can appear on the image of the
LCD screen. This is caused by objects directly in front of the rifle scope and illuminator.
Object such as a moderator/silencer or an iron sight, can aid the infra-red light emitted from
the illuminator, to reflect back into the scope causing flare. Rifles with long barrels give a
higher chance of causing flare. To reduce flare you should:
1. Use a sun shade on the front of the scope.
2. Add a none reflective coating or material to the moderator /silencer and barrel or if possible use a smaller diameter moderator.
3. Remove the front site (foresite).
4. Use higher scope mounts.
Lens flare can reduce the achievable night vision capability of the NiteSite equipment.
The NiteSite system functions, in night vision mode, with the use of infra-red light emitted
from the front of the infra-red illuminator at the front of the module. The NiteSite system
relies on the camera module receiving as much infra-red light through the scope, in
darkness as possible. Some scope manufacturers have a coating that reduces infra-red
light passing through the scope optic. This coating improves the image visibility at low light
levels. The NiteSite system is not as effective with scope lenses that have such coatings.
Always check the scope manufacturers instruction details prior to fitting the NiteSite to
ensure you get the best results from our product. For further information please contact our
Infra-red light illumination Reflected infra-red light returning presented on the to the IR camera can be reduced due to some scope optic coatings Harmful emitted infra-red

What is the difference between The NS50 has a range of 50 yards and the NS200 has a the NS50 and the NS200? range of up to 200 yards depending on the scope optic being used. The NS200 has a colour camera the NS50 has a black and white camera Why is the NS200 in black and The NS200 camera like the NS50 are infra-red cameras. white in darkness? They can detect in low light levels and total darkness, the infra-red light. This light is emitted from the LED's mounted in front of the LCD screen. The infra-red camera cannot detect the full spectrum of colour in this mode. This is why a white reflective light is detected. Depending on how reflective the objects in view are, will determine how the picture is made up. Light objects give a higher reflection than a non-reflective or a dark object. This results in a black and white picture image on the LCD screen in darkness Is my NiteSite water proof? No the NiteSite is not water proof only shower proof, cover the NiteSite in rainy conditions Can I upgrade my NS50 to an Yes, call the customer services for more details Is the NiteSite light sensitive? No the NiteSite can be used during daylight, even in bright sunlight.
