Handling and Disposal:
Do not burn or bury batteries. Do not puncture or
crush. Do not disassemble.
Recycle lithium batteries. Do not dispose of in the
trash.
Never allow loose cells to short circuit against battery
tabs or other conductive items. Keep loose cells and
battery packs out of reach of children.
If the electrolyte in the cells should get on your skin,
thoroughly wash with soap and water. If in the eyes,
rinse thoroughly with cool water. Immediately seek
medical attention.
Charging
Use only chargers rated for lithium cells. Be sure the
charger’s voltage and current settings are correct for
the battery pack being charged.
Charge batteries on a fireproof surface away from
flammable items or liquids.
Do not charge inside an automobile, especially while
driving.
Follow the manufacturer’s instructions for charging the
product and do not charge longer than recommended.
Unplug the charger when the battery is charged.
Recycle your old rechargeable batteries at one of the many
collection sites in the U.S. and Canada. To find the site
nearest you, visit www.call2recycle.org or call toll-
free 1-877-2-RECYCLE.

Listening Safely
Do not wear headphones, earphones, or earbuds while
operating a motor vehicle or riding a bicycle. This can
create a traffic hazard and could be illegal in some areas.
To protect your hearing, follow these guidelines:
Do not listen at high volume levels. Extended high-
volume listening can lead to permanent hearing loss.
Set the volume to the lowest setting. Then turn
on your audio device and adjust the volume to a
comfortable level.
Avoid increasing the volume. Your ears will adapt
to the volume level, so a level that does not cause
discomfort could still damage your hearing.
