Introduction
This document describes the installation and use of the DynaVox EyeMax for eye tracking.
The EyeMax enables a user to make selections by fixing his or her gaze at specific objects on
the device screen. Once the EyeMax is properly connected and calibrated, conversation,
environmental control, and even email and the Internet are only a blink (or gaze) away.
Be sure to read through the step-by-step instructions in this document to learn the proper
installation methods and ways to customize the software to best suit the needs and
capabilities of the device user.

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
NOTE
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:
NOTE
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.
CAUTION
You 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.
REFERENCE
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.
EyeMax User’s Guide 3
Part # 401216-C
Chapter 1: Introduction
EMERGENCY USE (INTENDED USE OF THIS PRODUCT)
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.
CAUTION
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
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 fatiguing to new users. This may be because they 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.

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 Standard 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 never gets close to the emission
limits set by these standards. A person using the EyeMax during regular operation 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.

PRODUCT CARE & HANDLING
To clean your Maestro/Vmax and EyeMax, first turn the Maestro/Vmax off and then wipe all
the hardware gently with a damp cloth or soft paper towel. You may dampen the towel with a
mild window cleaner to remove fingerprints, food particles, and dust.
Do not use tape or stickers on the Maestro/Vmax touch screen or on any of the plastic cases.
Additionally, do not cover the glass over the EyeMax camera or either of the infrared
transmitters. They are difficult to remove and may damage the device surfaces. Tape, stickers
and other sticky materials can damage the touch screen and interfere with the operation of the
devices.
Be sure to avoid getting any of your DynaVox devices wet. Never submerge them in water (for
example, in dishwater). If your devices accidentally get wet, shut them down immediately and
allow them to dry thoroughly. If after 24 hours you find that the devices seem to function
normally, there is probably no damage. If the devices fail to function or behave abnormally,
contact DynaVox Technical Support:
• US and Canada - Monday through Friday, 8:00 a.m. until 7:00 p.m. (Eastern Standard
Time): 1-800-344-1778.
• UK and Ireland - Monday through Friday, 8:30 a.m. until midnight: +44 (0) 1926 516250.
• Other European Countries, Asia Pacific, and the Middle East: please call the dealer from
whom you purchased your device.
You may need to ship the devices to DynaVox for repairs.
CAUTION
Never, under any circumstances, disassemble any of your DynaVox hardware - Maestro, Vmax, or
EyeMax. Doing so for any reason will void the warranty, and you will be responsible for the cost of
any required repairs.

Installation & Setup
This section describes how to properly attach and connect the EyeMax to your DynaVox
device (Maestro or Vmax).
NOTE
Since the device mount and mounting plate may be shipped separately, you may receive your
EyeMax kit from DynaVox before you receive the mount. If that is the case, the caregiver can still
connect the EyeMax to your Maestro/Vmax, charge the batteries, and begin to get familiar with
the Series 5 software. However, the entire system (EyeMax + Maestro/Vmax) must be properly
mounted before it can truly be put into use.

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.
NOTE
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.
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
the support leg and the battery door on the back of the device.
3. Extend the support leg to uncover the battery door.
4. Using a flat-head screwdriver (or a coin), loosen the two screws that hold on the battery
door by turning them to the left (counter-clockwise). The screws cannot be removed
completely; when they are loose, they will spring up slightly from the battery door.

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).
NOTE
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 left 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 Connecting 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 Battery on page 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.
NOTE
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 extended period, 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 aside.
d. Place the supplied metal handle in the grooves that originally held the support leg.
e. Replace the black plastic “feet” to hold the handle in place.
f. Unclasp the nylon handle on the bottom of the Vmax, and remove both halves from
the strap attachment points (once the EyeMax is installed, this handle is not needed).

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
NOTE
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.
NOTE
It is important to make sure that you use the EyeMax power supply/charger that shipped in the
