Safety Guidelines
Device Safety
Note: The following safety guidelines apply only to devices purchased from PRC-Saltillo or a subsidiary of PRC-Saltillo.
Emergencies
This device is not intended to be an emergency call device or sole communication aid.
Modifications
Do not attempt to modify the device, module, or any accessories. Modifications could create a safety hazard and make the equipment inoperative.
Contaminants
To prevent ingestion of bacteria, dust, and dirt, do not allow the user to chew on the product.
Cleaning, Maintaining, and Servicing
Do not service or maintain the device while in use. Disconnect the charger and turn off the device before cleaning.
If the device, module, or an accessory is damaged, call Service for assistance. Do not attempt to make repairs yourself.
Accessories
Do not use accessories, detachable parts, or materials not described in the manual.
Do not use accessories, detachable parts, or materials in any other way than described in the manual.
Mounting and Positioning
A qualified person should analyze positioning to prevent repetitive stress injuries to the user.
A qualified person should install and adjust any mounts, including switch mounts. Failure to install the mounting system according to the manufacturer's instructions may result in an injury to the user.
Do not place the device with an eye tracking or head tracking module attached where it is difficult to operate or difficult to disconnect from the charger.
Ensure hands are positioned on the back side of the kickstand and kept clear of the gap between the stand and the device to prevent pinching.

Vision and Hearing
The communication partner should ensure that the user takes frequent breaks to avoid eye strain.
Consult your vision care provider about device positioning considerations for the user.
Excessive volume or sound pressure level when using earphones or headphones can cause hearing loss over extended periods of time. Set the volume to a low level and increase it only enough that you can hear comfortably.
Ports and Connectors
Keep ports and connectors clean to maximize the service life of the device. Dirty cable connectors transfer contamination to the mating connector on the device and may degrade performance.
If the device has been exposed to water, each USB port must be completely dry before a USB cable is inserted into it. To remove moisture from the USB ports, shake the device several times with each USB port facing downward, and then use a microfiber cloth to wipe the device dry. You should then check the USB port area again. If moisture is still visible in any USB port, repeat the shaking and drying procedure.
Do not try to force a connector into a port. Be sure to insert the connector into the correct port and that the connector is turned so that it matches the orientation of the port.
Small Parts, Cords, Cables, and Straps
Cords, cables, and straps are potential entanglement or strangulation hazards. Consider this prior to placing these items with device users.
On a regular basis, visually inspect cables, cords, and connectors for damage or wear, especially where they are subject to extra stress. Cables and cords can become frayed or damaged from heavy use or with age. For example, a frayed cable could cause a battery charger/power adapter to short-circuit, posing a hazard to the user. If any cable, cord, or connector is damaged or worn, call Service for a replacement.
When unplugging a cable or cord, grasp the connector instead of the cable or cord itself to avoid damage or wear.
Always use cables, for charging or transferring vocabulary files, according to the instructions in the manual.
The stylus is a potential hazard for poking an eye.
If you are installing a head tracking or eye tracking module, the loose screws can be a choking hazard.
Small parts and loose adapters can present a choking or other hazard.
Damage
Do not use the device if the screen is cracked or broken.
Do not use an eye tracking or head tracking module if the lens is cracked or broken.
Interference
When operating this device in a medical environment, do not use it with any product that is not medically approved. Follow all rules for appropriate wireless device use.
Do not use the device or module close to sources of RF/RFID radiation or you may encounter interference. Move away, if possible, from the source of the interference.
Water
If the device has been exposed to water, each USB port must be completely dry before a USB cable is inserted into it. To remove moisture from the USB ports, shake the device several times with each USB port facing downward, and then use a microfiber cloth to wipe the device dry. You should then check the USB port area again. If moisture is still visible in any USB port, repeat the shaking and drying procedure.
The device is intended for use in normal communication situations. It is not waterproof. Do not spray or splash liquid directly on the device and use extreme caution when using it around water. As with most electronic devices, you should never use the device when you are actually in the water (for example, a pool or bath).

Touching the Surface
While the device is charging, touching the surface of the device with broken skin may aggravate a wound.
While the device is charging, high-risk groups should not touch the surface if there is a chance of burning the skin.
Implantable Medical Devices
A minimum of 6 inches should be maintained between a handheld wireless device and an implantable medical device, such as a pacemaker, implantable cardioverter defibrillator, vagus nerve stimulator, shunt, or stent, to avoid potential magnetic interference with the medical device. A person who has an implantable medical device:
should always keep the device a minimum of 6 inches from their implantable medical device;
should not carry the device in a breast pocket;
should move the device away from themselves if they suspect it is interfering with the implantable medical device;
should read and follow the directions from the manufacturer of the implantable medical device.
If you have any questions about using the wireless device with an implantable medical device, consult your health care provider.
Software/App Safety
The software is not intended to be an emergency call app or a sole communication aid.
Use the software safely while texting. Do not text while performing another task or activity.
The communication partner should ensure that the user takes frequent breaks to avoid eye strain.
Consult your vision care provider about positioning the device for the user to view the software.
When adjusting volume in the software, excessive volume or sound pressure level when using earphones or headphones can cause hearing loss over extended periods of time. Set the volume at a low level and increase it only enough that you can hear comfortably.
If the software stops functioning, contact the Service department.
Eye Tracking Safety
Note: The following safety guidelines apply only to devices with an attached eye tracking module purchased from PRC-Saltillo or a subsidiary of PRC-Saltillo.
Fatigue
While the user is getting used to eye tracking, take frequent breaks to rest the user’s eyes and relax his or her concentration.
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 eye tracking. If you are experiencing fatigue or dry eyes, start off slowly and limit the length of your eye tracking sessions to your comfort level. Consult a medical professional regarding moisturizing eye drops, which may be helpful to combat dryness.
Seizures
Some people may have epileptic seizures triggered by light flashes or patterns. This may occur while presented with successive pictures or video material, even if they have never had a seizure before. Observe the individual using the system. Move the person away from the system immediately and consult a physician if the individual shows the following or similar symptoms: involuntary movements, disorientation, convulsions, loss of awareness, or altered vision.
Infrared Emissions
Eye tracking systems use infrared (IR) technology. Certain medical devices are susceptible to disturbance by IR emissions. Do not use the eye tracking system when in the vicinity of such susceptible medical devices. If you have questions about the susceptibility of a medical device, consult the manufacturer of the medical device or your health care provider.
If you have questions about the susceptibility of a medical device to the infrared technology that is part of your eye tracking system, consult the manufacturer of the medical device or your health care provider.
