Charge your Danew mobile device using a compatible Danew charger, or a
high-power USB port on a PC. Chargers that do not comply with these stand-
ards may be unsafe, and may cause slow charging, product damage, or re
-
duced device performance.
• Your mobile device will not charge if the temperature is too high or low.
• Only use Danew-approved batteries, which contain safety circuitry and
are designed to give the best performance in your Danew mobile device.
Prolonged use of any device may cause discomfort in hands, fingers, arms,
-
neck, and other parts of your body, and may cause eyestrain and headaches.
It is good practice to use your device in a safe area with comfortable ambient
lighting, and take frequent breaks if you feel discomfort. Seek medical advice
if symptoms persist.
In rare cases, flashing patterns or lights, for example in video games or mov
-
ies, may cause seizures or blackouts. If you suffer any seizures or blackouts,
or have a history of seizures, stop using your device and seek medical advice.
Warning:
Exposure to loud noise from any source for extended periods of
time may affect your hearing. The louder the sound, the less time is required
before your hearing could be affected. To protect your hearing:
• Limit the amount of time you use headsets or headphones at high volume.
• Avoid turning up the volume to block out noisy surroundings.
• Turn the volume down if you can’t hear people speaking near you. If you
experience hearing discomfort, including the sensation of pressure or full
-
ness in your ears, ringing in your ears, or muffled speech, you should stop
listening to the device through your headset or headphones and have your
hearing checked.
