Important safety and handling information
Plastic bag notice
Danger: Plastic bags can be dangerous. Keep plastic bags away from babies and
children to avoid danger of suffocation.
Built-in rechargeable battery notice
Danger: Do not attempt to replace the internal rechargeable lithium ion
battery. Replacing the original battery with an incompatible type may result
in an increased risk of personal injury or property damage due to explosions,
excessive heat, or other risks.
Do not attempt to disassemble or modify the battery pack. Attempting to do
so can cause harmful explosions or battery fluid leakage.
When disposing of the battery, comply with all relevant local ordinances or
regulations. Do not dispose the battery pack in municipal waste. Dispose
used batteries according to the instructions.
The battery pack contains a small amount of harmful substances. To avoid
injury:
•
Keep the battery pack away from open flames or other heat sources.
•
Do not expose the battery pack to water, rain, or other corrosive liquids.
•
Do not leave the battery in an extremely high temperature surrounding
environment.
•
Avoid short-circuiting the battery pack.
•
Keep the battery pack out of reach of small children and pets.
•
Do not leave the battery in an extremely low air pressure surrounding
environment. It may result in an explosion or the leakage of flammable
liquid or gas from the battery.
To extend battery life, we recommend charging the battery to at least 30
to 50% capacity each time, and recharging it every three months to prevent
over discharge.
Caution about high volume usage
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.
