SYSTEM REQUIREMENTS
In order to use the EyeMax properly, you must have the following:
• DynaVox speech generating device. The EyeMax connects to two different models of
speech generating device:
• DynaVox Maestro
• DynaVox Vmax+ Dual Core
See the picture on the previous page for reference.
• DynaVox Series 5 Software: No matter if you use a Maestro or a Vmax+, your speech
generating device must be running version 1.07.2 (or later) of the Series 5 Software.
• Mounting system. The EyeMax System (EyeMax + speech generating device) is not a
hand-held system. It must be securely mounted for proper positioning.
ABOUT THIS USER’S GUIDE
This document contains descriptions of and instructions for performing the basic operations of
your EyeMax. Throughout the text, you will find the following kinds of comments:
This document offers notes on making the most of your communication system. These notes are
designed to highlight features that can be used to make the device a better fit for an individual
user, or point out other important considerations.
Y ou should always be sure to read the notes beside the caution symbol. These notes contain very
important information to help you use your DynaVox hardware safely, and to prevent device
damage and loss of information.
Many of the topics in this document are explained in more detail in the Series 5 Searchable Help
that can be launched on your Maestro/Vmax (or the CD and/or DVD that came with your Maestro/
Vmax). The reference notations include a key word or phrase that can be used to quickly find the
topic in the Searchable Help.

EMERGENCY USE (INTENDED USE OF THIS PRODUCT)
CAUTION
The Maestro/Vmax and EyeMax are intended for everyday communication situations. They
should not be relied upon as a means of communicating emergency medical information. We
recommend having multiple ways to communicate information during a medical emergency.
The EyeMax emits infrared light, which may interfere with infrared-controlled devices. Do not use
the EyeMax in the same room with any infrared-controlled device if device failure could affect the
safety or health of the user.
PHYSICAL STRAINS
Chapter 1: Introduction
There are two types of strain that can occur from using any kind of eye tracking device: neck
strain and eye strain. This is true for using computer monitors as well. Recommendations for
alleviating such ‘monitor eye strain’ may be found by browsing to this Web site:
www.mayoclinic.com/health/eyestrain/WL00060.
If, at any time, you notice discomfort, pain, or fatigue in either your neck or your eyes, stop
using the EyeMax and rest until you feel well again.
The length of time that the EyeMax can be used before feeling strain or fatigue will vary from
person to person. You should listen to your body and rest when it tells you.
Trying out the EyeMax may initially be fa tiguin g to new use rs. This may be because the y tend
to strain their eyes to reach and concentrate upon each target. A typical user will quickly grow
accustomed to the eye tracking process, and use of the system will soon become less
fatiguing.
EyeMax User’s Guide 3
Part # 401216-C
Chapter 1: Introduction
LIGHT EXPOSURE
The EyeMax contains light-emitting diodes (LEDs) that emit light in the near-infrared spectra.
This type of infrared (IR) light occurs naturally in sunlight and also in light from incandescent
lamps.
Several national and international organizations provide guidelines for human exposure to
optical radiation, and recommend exposure limits for the eye and skin. The most prominent
are: the American Conference of Governmental Industrial Hygienists (ACGIH)1-2 in North
America, and the International Commission for Non-Ionizing Radiation Protection (ICNIRP,
1997). In the European Union, there is an Optical Radiation Directive that employs the ICNIRP
exposure limits in the workplace. Other organizations recommend product-safety emission
limits (ANSI, 2005, 2000, 2007; CIE, 2002; CENELEC, 2002; IEC, 2007; CDRH, 1995).
Currently, there are two sets of product safety standards that apply to the use of lamps—
including solid-state lamps (LEDs) worldwide. These are:
• The CIE Lamp Safety Standard: CIE Standar d S009/E-2002, Photobiological Safety of
Lamps and Lamp Systems.
• The EN 60825-1 Laser Product Safety Standard
The maximum level possible with the EyeMax in any setting ne ve r ge ts close to the em issio n
limits set by these standards. A person using the EyeMax during regular oper ation is exposed
to less than 0.1% of the accepted long-time exposure according to EN 60825-1/A1-A2. This
exposure is also well within the safety guidelines given in the book, 1996 TLVs and BEIs, by
the American Conference of Governmental Industrial Hygienists.

Installing/Replacing the Vmax Battery
When your Vmax is shipped, the battery is not installed. Before you can turn on your Vmax,
you must install and charge the battery.
You may also follow the steps below if you need to replace the battery in your device with a new
battery from DynaVox Technologies. If the battery in your Vmax becomes unable to maintain
power after being charged, it could need to be replaced. You can order a replacement battery by
contacting DynaVox Customer Service/Sales Support.
Chapter 3: Installation & Setup
To install (or replace) the battery in your Vmax:
1. If you are replacing a battery, turn the device off and, if necessary, disconnect the charger.
2. Lay your device face down on top of a soft cloth on a flat surface. You should be looking at

5. Lift the battery door away from the device’s case and put it in a safe place (you will need it
again if you ever disconnect the EyeMax from your Vmax).
If you are replacing the current battery, lift it out of the battery well and set it aside.
6. Locate the connector slots on the bottom of the battery and the connector in the lef t side of
the battery well on the device case. Then, place the battery into the device case so that
the connectors fit together. The battery should lie flat in the battery well.
At this point, you must connect the battery door that is attached to the EyeMax, and make the
necessary cable connections between the two devices. Continue with Connect ing EyeMax to
Vmax on page 14.
Connecting EyeMax to Vmax
The EyeMax is already attached to a replacement battery door for your Vmax. After you have
installed the battery, you should set aside the original battery door that came with the Vmax,
and attach the replacement battery door with the EyeMax.
After the battery door is in place, you can then make the necessary cable connections
between your EyeMax and your Vmax.
These instructions pick up where Installing/Replacing the Vmax Bat tery on p age 13 left off.
To continue:
1. Place the EyeMax battery door on your Vmax and tighten the screws by turning them
clockwise (to the right). You should only have to turn them a quarter-turn or half-turn.
After you replace the battery door, make a note of both your Vmax’s serial number, and the
EyeMax’s serial number. They are printed on the label on the battery door. Pull the Vmax+ Quick
Start guide out of the Vmax shipping box, and write the two serial numbers in the space provided
on the last page. This information will be handy if you ever need to contact DynaVox Technical
Support about your Vmax or your EyeMax. You will also need to write the Vmax serial number on
the registration card. Set the registration card aside. You can fill it out while the battery is charging.
2. If you plan to keep the EyeMax connected to your Vmax for an ex tended per iod, complete
this step. (If you plan to disconnect the EyeMax after a brief period, proceed to step 3.)
a. Use the supplied Allen wrench to loosen the black plastic “feet” that hold the support
leg in place on the back of the Vmax.
b. Remove the feet and set them aside.
c. Lift the support leg away from the Vmax and set it asid e.
d. Place the supplied metal handle in the grooves that originally held the suppo rt leg.
e. Replace the black plastic “fee t” to hold th e handle in place.

CHARGING THE BATTERIES
Each of the DynaVox devices (Maestro/Vmax and EyeMax) has an internal battery, and they
must all be charged. It can take up to 4 hours to completely charge the batteries. There are
three things to remember about these batteries:
• They will both charge at the same time.
• You cannot overcharge the batteries. You can leave the charger plugged in continuously,
and this will not harm the batteries in any way.
• You can still use the EyeMax system to communicate while the batteries are charging.
When your Maestro/Vmax battery begins to run out of power, the low battery icon will appear
on the right side of the title bar on the touchscreen (refer to the picture below). If you see this
icon, you should plug in your device to conserve the remaining power, and you should
recharge the batteries as soon as possible. The icon will remain visible until the batteries are
recharged.
LOW BATTERY ICON IN THE TITLE BAR
If the EyeMax battery begins to run out of power, the charging indicator LED on the left side of the
EyeMax will blink (see Left Side on page 7). You should recharge the batteries as soon as
possible.
If the batteries completely run out of power, your DynaVox devices will automatically shut
down. Any unsaved programming will be automatically saved before the devices shut down.
You will need to either charge the batteries or plug in the charger before you can turn the
devices on again.
It is important to make sure that you use the EyeMax power supply/charger that shipped in the
EyeMax box. The Maestro/Vmax charger will not work with the EyeMax.
To charge the device’s battery:
1. The EyeMax power supply/charger is shipped in two pieces – the power cord and the DC
adapter . Connect these two pieces.
2. Plug the charger jack into the charger port on the left side of the EyeMax.

MOUNTING THE EYEMAX SYSTEM
The EyeMax System (Maestro/Vmax and EyeMax) must be mounted at the appropriate
distance from and angle to the user in order to work properly.
If you are connecting your EyeMax to a Vmax, you should remove the support leg from the back of
the Vmax if you intend to keep the EyeMax attached to it for a long time. Refer to Installing/
Replacing the Vmax Battery on page 13.
Proper Mounting Position
The following specifications describe the “proper mounting” of the EyeMax System:
•Distance: 17 - 28 inches from the user’s face (20 - 24 inches is the “optimal distance”)
• Angle: parallel to the user’s face
• Tilt: tilted to match the user’s head position
The number of different head positions the user has throughout the day should be an important
consideration when considering mounting components and options.
To set the proper height for the Maestro/Vmax: imagine a line, perpendicular to the user’s
face, extending out from the user’s eye. This line should intersect the top of the Maestro/Vmax
touch screen. Refer to the diagram below.
GUIDELINES FOR PROPER HEIGHT, DISTANCE, AND ANGLE SETTINGS
Make sure that the user’s eyes are approximately 17 - 28 inches away from the Maestro/Vmax
touch screen. This is the acceptable distance for pr oper focus of the Eye Max (20 - 24 inches is
the “optimal distance”).

NOTE
If the user is wearing glasses, positioning the MaestroVmax below the user’s eyeline may help to
reduce the possibility of glare reflecting off of the glasses’ lenses. Refer to the alternate angle
diagram below as a guideline. You should adjust the height and the tilt of the device to best suit
the user’s needs.
ALTERNATE ANGLE FOR USERS WITH GLASSES
For users leaning to the side, it is helpful to t ilt the EyeMax System sideways as well . Rotating
the EyeMax System to match the user’s head angle will greatly increase the allowed head
movement.
PROPER TILT DIAGRAM
The mount that you choose should be easily adjustable for situations when the user or the
EyeMax System frequently need to change position.
