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.
If the stand is removed, it becomes a potential hazard for poking an eye. Closing the stand could pinch a finger.
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.

Eye Tracking Safety
The following safety guidelines apply to devices with an attached eye tracking module purchased from PRC-Saltillo only.
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. Moisturizing eye drops can be helpful to combat dryness.
Seizures
Some people may have epileptic seizures triggered by light flashes or patterns. This may occur while presented 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 uses 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.
