Introduction to the Presenter
X-Ray, Document & 3-D Object to Video Transfer System
TheNavitarPresenterisanidealpresentationtool.It
enables you to easily convert large documents and blue
prints, 14” x 17” medical X-rays and MRIs as well as 3-D
objects into high definition video images which can be
projected through a video projector, viewed on a TV
monitor or imported into a computer.
The on-screen resolution in incredible. The lack of noise
and outstanding contrast is amazing. Images are pro-
duced with such superior contrast and vivid color rendi-
tion that they can be shown as large projected images
without losing clarity or legibility. Details are clear and
easy to examine.
The Presenter is extremely versatile, making it ideal for
telemedicine and medical applications, as well as use in
courtrooms,boardrooms,auditoriumsandtrainingrooms.
Youcan present your imageson a TV monitoror video
projectorforlargegrouppresentations,orinputtheminto
yourPCfor medical archiving. And because it’scapableof
zooming out to view images as large as 17” x 23”, it can
also be used for tele-engineering applications to view
large C-size documents, blueprints, architectural draw-
ings and 3-D objects.

Safety Precautions
To prevent damage to the equipment and operating
personnel, please observe the following precautions:
Make sure that the voltage source contains a satisfactory
path to ground.
Do not operate the unit where water or other fluids can
come into contact with the electrical components.
Maintain a six inch air space around all sides of the
equipment to allow for proper ventilation.
When changing the bulb:
Disconnect the electrical supply.
Allow the unit to cool.
Use only an EVD36V-400W (36 volt, 400 watt) lamp or the
equivalent.Higherwattage lamps willcausesevere
internaldamagetothe camera and electronics.
Thereare no userserviceablecomponents(other than
changing the lamp). Opening the unit will expose danger-
ous voltage levels and sensitive electronic components.
All repairs should be performed by a qualified technician.
To protect the unit from damaging condensation and
thermal shock, certain procedures must be followed:
Incold weather, keep theunit away from moisture.
Eitherkeeptheunitwarmduringtransportation or allow
sufficient time for it to warm up at the destination. (The
goal is to prevent warm, moist air from striking the cold
electronic and optical components which will cause
damagingcondensation).
Warning
Never operate a cold projector to warm it up.

Features and Functions
RS-232 Remote Control
In the past, most products were controlled by simple
contactclosure.Today’sadvanced boardroom control
systems,however, are using RS-232 for control oftheAV
componentsandroomfunctions.
With the Presenter, you can electronically control the
video camera, zoom lens and X/Y image positioning
functions of your video transfer unit by RS-232 control
from your PC computer or boardroom control system via
the RS-232 control port, (9-pin sub D socket) located on
the video output panel. Use a 9-pin D-Sub male to 9-pin
D-Sub female for connection (1:1, shielded).
