2.1Avoiding Hearing Damage
Permanent hearing loss may occur if earphones, headphones or speakers are used at high volume. To prevent this,
the volume should be set to a safe level. You can become desensitized over time to high sound levels which may then
sound acceptable yet still could be damaging your hearing. If you experience symptoms such as ringing in your ears,
please lower the volume or stop using the earphones/headphones. The louder the volume, the less time is required
before your hearing could be affected.
Hearing experts suggest the following measures to protect your hearing:
•Limit the amount of time you use earphones or headphones at high volume.
•Avoid turning up the volume to block out noisy surroundings.
•Turn the volume down if you cannot hear people speaking near you.
To establish a safe volume level:
•Set your volume control at a low setting.
•Slowly increase the sound until you can hear it comfortably and clearly, without distortion.
2.2Temperature
This device can be made to operate in two different modes, Portable and Mounted. When the device is in Mounted
mode it is allowed to run at a higher temperature; it sets the maximum allowable environmental temperature to its highest level. The risk with running the device in this mode is that it can reach temperatures in which prolonged use with
direct skin contact may cause permanent bodily harm. Portable mode sets the maximum device temperature shut
down limit to a lower temperature, reducing the risk for permanent bodily harm caused by prolonged exposure to the
skin. Only choose Mounted mode when the device is mounted on a wheelchair, table, etc, with a proper mounting
system.
Due to use in direct sunshine or in any other hot environment the Tobii Dynavox I-Series+ device may have hot surfaces. There is a built in temperature sensor that monitors the temperature. If the sensor detects temperatures above
the temperature specified in Table D.1 Maximum Allowed Temperature, page 94 for portable mode and mounted
mode the device will automatically trigger a Windows Shut Down or Hibernate (depending on Windows Power Button configuration) to not cause the User any risk of harm. It may take a while before Tobii Dynavox I-Series+ device
can be restarted as the unit may first need time to cool down.
2.3Power Supply and Batteries
The Tobii Dynavox I-Series+ device uses Lithium Ion batteries. These batteries have a storage temperature range of
between -20 ℃/-4 ℉ and 40 ℃/104 ℉ within 6 months.
If you are in a hot environment, be aware that it can affect the ability to charge the batteries. The internal temperature
has to be between 0 ℃/32 ℉ and 45 ℃/113 ℉ for the batteries to charge. If the internal battery temperature raises
above 45 ℃/113 ℉ the batteries will not charge at all.
Move the Tobii Dynavox I-Series+ device and the batteries to a cooler environment to let the batteries charge
properly.
Avoid exposing the batteries to fire or to temperatures above 50 ℃/122 ℉. These conditions may cause a battery to
malfunction, generate heat, ignite or explode. Be aware that it is possible, in a worst case scenario, for temperatures
to reach greater than those stated above in, for example, the trunk of a car on a hot day. So, storing the device, with
batteries installed, in a hot car trunk could conceivably lead to a malfunction.
Do not disassemble or harm the battery. Pay attention to the environmental laws and regulations which apply in your
area when disposing of batteries.
For safe operation of the Tobii Dynavox I-Series+ device, use only charger, batteries and accessories approved by
Tobii Technology.

2.6Infrared
The Tobii Dynavox I-Series+ emits pulsed infrared (IR) light both from the eye tracker and from the Environmental
Control Unit. Other devices controlled by IR or susceptible to disturbance by IR light might be affected by the IR light
emitted from the Tobii Dynavox I-Series+. Do not use the Tobii Dynavox I-Series+ in the vicinity of such devices if
their functionality is of critical importance.
2.7Epilepsy
Some people with Photosensitive Epilepsy are susceptible to epileptic seizures or loss of consciousness when exposed to certain flashing lights or light patterns in everyday life. This may happen even if the person has no medical
history of epilepsy or has never had any epileptic seizures.
A person with Photosensitive Epilepsy would also be likely to have problems with TV screens, some arcade games,
and flickering fluorescent bulbs. Such people may have a seizure while watching certain images or patterns on a monitor, or even when exposed to the light sources of an eye tracker. It is estimated that about 3-5% of people with epilepsy have this type of Photosensitive Epilepsy. Many people with Photosensitive Epilepsy experience an "aura" or
feel odd sensations before the seizure occurs. If you feel odd during use, move your eyes away from the eye tracker.
2.8Electricity
Do not open the casing of the Tobii Dynavox I-Series+ device, since you may be exposed to potentially hazardous
electrical voltage. The device contains no serviceable parts.
2.9Child Safety
The Tobii Dynavox I-Series+ are advanced computer systems and electronic devices. As such they are composed of
numerous separate, assembled parts. In the hands of a child certain of these parts have the possibility of being separated from the device, possibly constituting a choking hazard or another danger to the child.
Young children should not have access to, or the use of, the device without parental or guardian supervision.
2.10Environmental Control
The GEWA Programmable IR Remote Control — Environmental Control Unit (ECU) is not to be relied on as the only
method of interaction with IR controlled devices.
2.11Gaze Interaction
Some people may experience a certain amount of fatigue (due to intentional eye focusing and hard concentration) or
even a dryness of the eyes (due to less frequent blinking) when first getting used to Gaze Interaction. If you are experiencing fatigue or dry eyes start off slowly and limit the length of your Gaze Interaction sessions to your comfort level.
Remoisturizing eye drops can be helpful to combat dryness.
Any use of the Tobii Dynavox I-Series+ outside the intended use and together with any third party software or hardware that changes the intended use is a risk and nothing that Tobii Dynavox can take any responsibility for.
The Tobii Dynavox I-Series+ has several built-in features. Some of these come standard and some can be ordered as additional

Tobii Dynavox I–12+ and I–15+, see Appendix E Technical Specifications, page 95.
Figure 4.1 Battery with Indicator for Remaining Capacity
4.1.1Hot Swappable
You can remove/replace one battery without switching off the Tobii Dynavox I-Series+ device, providing that the remaining battery is sufficiently charged. The remaining battery requires being at least ~10% charged to maintain device operation.
Please allow the Tobii Dynavox I-Series+ device a few seconds to detect the newly inserted battery before removing
the other battery.
4.2Charging
The batteries shall only be charged using the included adapter, or by using theI-Series Table Charger (not included, separate
purchase required). When the Tobii Dynavox I-Series+ device is shut down and the adapter is plugged in, the charging of completely discharged batteries may take up to 5 hours. The device can be used while the batteries are being charged, though this
may affect the time a battery takes to reach full capacity.
To be sure that charging takes place in both the Tobii Dynavox I-Series+ device and when using the I-Series Table
Charger, be sure to plug the adaptor into both the wall socket and the device or Charger BEFORE you insert the
batteries.
The batteries will only charge when its capacity is 95% or lower.
The expected battery lifetime is 500 charge/discharge cycles. After that, the capacity of the battery will decrease by about 20%
in usage time.
For battery storage and charging temperatures, see 2 Safety, page 12 .
Click on the battery icon,, in the Notification area to see the remaining charge of the battery, which is installed in the
device.
You may also, at any time, check the status of a battery by pressing the indicator button on the face of the battery. Five LEDs
(light-emitting diodes) will indicate the remaining charge level. For example, three lit LEDs indicate a 60% remaining charge,
see Figure 4.1 Battery with Indicator for Remaining Capacity, page 23.
When charging, the highest capacity LED indicator will be blinking.
The lowest capacity LED indicator (the "20" LED), will also blink when the indicator button is pressed if the battery’s
capacity has dropped below 10%. So don’t rely upon the blinking of the 20% indicator as a guarantee for charging.
If the batteries have been deeply discharged (this can happen by leaving an empty battery inserted in the
Tobii Dynavox I-Series+ device without the power adapter connected) you may not see any indication of charging
when you reconnect the adapter properly to the Tobii Dynavox I-Series+ device or the Table Charger. It may take
some time (even up to 20 minutes) before you see an LED indication that any charging is taking place. The battery IS
being charged during this duration though it is a recovery charge raising the level enough to begin normal charging.
4.3Inserting and Releasing the Batteries
For safety reasons, the Tobii Dynavox I-Series+ device is delivered without the batteries inserted. The batteries are delivered
only partially charged. The Tobii Dynavox I-Series+ device can be used right away. It is nevertheless recommended that the batteries are charged for at least two hours before using the device.
4.3.1Inserting the Batteries
To insert the batteries:
1. Insert a battery in the battery compartment.
2. Press the battery until it locks in place. You should hear a click that confirms that the battery is in a locked place.
4.3.2Releasing the Batteries

•Press the power button on the right side of the device. (Position 9 in Figure 3.2 Bottom, Left and Right Side, page 18)
•Activate a configured Switch (see 6.3 Switches).
When you have started the device, the Power LED will shine blue or green depending on if the device is connected to AC or on
batteries. For more information about the LED Behavior, see Appendix C Computer Device States of Operation, page 92.
5.1.1Password Information
The Tobii Dynavox I-Series+ device is configured to start up, using the operating system present, without a password. Though
unusual, there are situations in which the password window could plausibly pop up; for example, when creating a new user in
the operating system, when returning from the operating system’s sleep mode or when downloading software updates from the
internet.
Creating a new windows user and downloading updates from the internet could possibly compromise the system and
software settings of the operating system that have been set and installed at Tobii Technology.
Should the password window pop up, requiring a password, the default password on all Tobii Dynavox I-Series+ devices is, "Is-eries" (case sensitive). In order to type in the password use the Windows On-Screen Keyboard or an external USB keyboard
(not included).
If you decide to change the password, be sure to write it down in a safe place for later use.
Suggested place to keep new password: ________________________
Without the operating system’s access password, Tobii Dynavox Support may be unable to assist you with any future
difficulties.
5.1.2Tobii Dynavox I-Series+ Welcome Guide
When you start your Tobii Dynavox I-Series+ Device for the first time you will be greeted by the Tobii Dynavox I-Series+ Welcome Guide. The guide is a setup wizard that will walk you through some steps that will help you make the most of your device.
Follow the instructions and select on Next to get to the next page of the Guide.
After the Welcome Guide is completed, the I-Series will perform an auto-restart.
5.2Shutting Down the Device
The device should be shut down using one of the following ways:
•Use the start menu in Windows (recommended when possible).
•Press a configured Switch for two to seven seconds.
Pressing the Switch for more than 7 seconds will shut down the device immediately, disregarding any unsaved
changes.
•Through the communication software installed on the device
Should you be unable to shut the device down using either of the above, you can hold the power button on the right side of the
device down for seven seconds. The device will consequently shut down immediately, without waiting for open applications to
close.
This will not work if the side buttons have been disabled in the Tobii Dynavox I-Series+ Control Center. For more information, see 6.1.2 Disable All Buttons, page 52.
This is not considered a "clean" Windows shut down and is thus not recommended unless completely necessary.
5.3Using Gaze Interaction
The Tobii Dynavox I-Series+ operate with precision regardless of glasses, contact lenses, eye color or light conditions.
Gaze Interaction enables you to control the computer with your eyes using either Gaze Enabled applications (like
Tobii Dynavox Communicator /Tobii DynaVox Compass) or through the two types of Windows Control. See 5.4.1 WindowsControl Type, page 29.
5.3.1Positioning
Figure 5.1 Positioning
The Tobii Dynavox I-Series+ is designed to work optimally when it is parallel to the user’s eyes at a distance of about 60 cm
(23.5 inches), see Figure 5.1 Positioning, page 27.
Figure 5.2 Positioning when Users Leaning Sideways or Those Lying Down
This means that for those users leaning sideways or those lying down the Tobii Dynavox I-Series+ also needs to be tilted in order to keep the users eyes parallel to the screen and at the optimal distance, see Figure 5.2 Positioning when Users LeaningSideways or Those Lying Down, page 27.
Make sure the user is placed comfortably in relation to the optimal positioning of, and distance from, the unit. Be
aware also that the user’s comfort, as well as the Gaze Interaction performance, will be enhanced if the sun is not
shining directly on the screen or into the user’s eyes.
The user should be positioned at the optimal distance to allow for the best possible Gaze Interaction.
The Tobii Dynavox I-Series+ allows for extensive Freedom of Head Movement. Once the Tobii Dynavox I-Series+ is properly
calibrated and placed in front of the user, no further adjustments are required.
The Tobii Dynavox I-Series+ produces an industry leading sized track box with the approximate dimensions of 30 cm × 20 cm
× 20 cm / 11.8 in × 7.9 in × 7.9 in (Width × Height × Depth). The Track Box is an invisible box positioned approximately 60
cm (23.5 in) straight out from a point just above the middle of the screen.
At 70 cm (27.5 in) the Tobii Dynavox I-Series+ allows for lateral Freedom of Head Movement in an area of about 50 × 36 cm
(20 × 14 in) or 35 × 30 cm (13,8 × 11,8 in) depending on which Eye tracker the Tobii Dynavox I-Series+ is equipt with. For
more information, see Appendix E Technical Specifications, page 95.
In order to function properly for Gaze Interaction the user needs at least one eye in the track box at all times.
5.3.3Track Status Viewer
Use the Track Status viewer (see 5.3.3.1 Showing Track Status , page 28 for more information on how to open the Track Status
viewer) to help determine the optimal height and horizontal positioning for Gaze Interaction with the Tobii Dynavox I-Series+.
•Ideally, the two dots that represent the user’s eyes should be in the middle of the Track Status viewer.
•Use the distance meter on the right hand side of the Track Status viewer to determine the optimal distance the user
should be from the Tobii Dynavox I-Series+.
•The white triangle in the distance meter should hover near the center, within the green, when the optimal distance from
the Tobii Dynavox I-Series+ is reached.
For information about calibration of the Tobii Dynavox I-Series+ see 7.2 Calibration, page 67. Also check the lighting
conditions, related to what is mentioned above, when calibrating.
5.3.3.1Showing Track Status
The track status viewer is a window/dialog where you can verify that the Gaze Interaction recognizes your eyes and that you are
well positioned in front of the device.
Open the track status viewer in one of the following ways:
•Open Tobii Dynavox Gaze Interaction Settings > Calibration and select the Track status button.
•Right-click (long-hold finger on icon for touch screen right clicking) on the Tobii Dynavox Gaze Interaction Settings
icon,
, in the Notification area and select Show track status.
For extra assistance in positioning, there is a Positioning guide that will show itself automatically in the bottom-right corner of
your monitor.
The Positioning guide is a visual guide that combines the function of the Track Status viewer with six different image based
instructions to help the user with correct positioning.
The 6 instructions direct the user to:
1. Move head down.
2. Move head up.
3. Move head to the right.
4. Move head to the left.
5. Move head closer to the monitor.
6. Move head farther away from the monitor.
Move head closer to the monitor.Move head to the right.
The Positioning guide will automatically disappear when the user’s positioning is improved in the way that is directed by the
guide.
Some users may not want the Positioning guide to pop up every time their eyes leave optimal positioning.
To turn On or Off the automatic Positioning guide, see 7.6 System Settings, page 75
5.4Using Windows Control
Windows Control allows you to access the desktop and all applications of your Windows computer with Gaze Interaction.
5.4.1Windows Control Type
Windows Control can be used in two different modes
•Gaze Selection
Gaze Selection is a very precise and fast input method that allows you advanced Windows access but with a simple to
use interface. No accidental clicks, no unintentional mouse pointer movements. You can relaxed gaze around at your
Windows desktop, your software application, web page or movie, when you have decided what action you want to take
next, you select your tool of choice from the toolbar and look back at the target area to make your selection.
Gaze Selection is ideal for normal to advanced Windows access where you want the full accessibility to control basically
any Windows software without the need for fast decisions and movements. It can be controlled using either Gaze (dwell)
or switch activation method for even more control and speed.
•Mouse Emulation
Mouse Emulation gives you full control of your mouse pointer, just like you would do with a physical mouse input device.
You can left click, right click, double click, zoom, scroll and much more. You basically can control any Windows software
that works with mouse clicks. With some practice you could achieve as high precision as with any other mouse pointer
device. Mouse Emulation is ideal for emergent (sensory) to advanced Windows usage and for software which teaches
the usage of eyegaze. You can hide the Mouse Emulation menu if you want to limit the functionality or avoid distraction
by pressing the F2 button on your keyboard.

5.4.3Using Gaze Selection
The Gaze Selection mode of Windows Control makes it possible for the user to control a standard Windows desktop operating
system with a two step selection method which reduces the risks of unwanted clicks. It also prevents the following of the mouse
cursor with your gaze as opposed to the controlling of it (there is no floating mouse cursor in Gaze Selection).
1. The first step is to select the desired Task from the docked Taskbar by looking at it.
2. The second step is to look at the desired portion of the screen (or icon on the screen) where you want to execute the
Task. An automatic zoom function is enabled, ending in the selection of the icon or execution of the task.
All functions in Gaze Selection are Touch and Mouse enabled which makes it easier for a Caregiver or Assistant to
help the user if needed. The Caregiver or Assistant can select a Function/Task or change the settings for the user
much easier.
