cause discomfort or burns. Do not sleep on your device or its power adapter, or cover them with
a blanket or pillow. Be aware of this issue if you have a physical condition that affects your
ability to detect heat against your skin.
Your device may generate additional heat when charging or using certain features, for example
when powering external devices such as wired headsets. Use extra care when operating the
device in these modes.
Hearing Loss
Prolonged exposure to loud sounds (including music) can cause hearing loss. To prevent
possible hearing damage, avoid listening at high volume for prolonged periods of time.
Continued exposure to high volumes and background noise can make loud sounds seem quieter
than they actually are. Check the volume before using headphones or earphones.
Repetitive Stress Injury
Repetitive movements using the activities like gesturing or playing games on any media device
can lead to occasional discomfort in your hands, wrists, arms, shoulders, neck, or other parts of
your body. If you experience any discomfort, put the media device down and take a break. If you
experience any of these symptoms, stop using the media device. If you’re still experiencing
discomfort after your break, consider calling a doctor.
Seizures
A small percentage of people may experience seizures or blackouts that are triggered by visual
stimuli, such as light flashes or patterns. Those seizures most often occur in children or younger
people, and can be experienced by people who have never had seizures or blackouts before.
Stop using the media device immediately if you suffer from blackouts or seizures and contact a
doctor. If you have a history of seizures, blackouts, or epilepsy, consult with a doctor before
using the media device.
Medical Device Interference
Your media device uses radios and other components that emit electromagnetic fields, and also
contains magnets inside the product. Headsets and headphones used with the media device
may also contain magnets. These electromagnetic fields and magnets may interfere with
pacemakers and other implanted medical devices.
Battery
This device contains a lithium-ion battery, which is a sensitive component that can cause injury
if damaged. Do not attempt to remove the battery. Contact Google or a Google authorized
service provider to replace the battery. Replacement by non-qualified professionals can damage
your device. Use of an unqualified battery may present a risk of fire, explosion, leakage, or other
hazard.
