hot or cold battery may not work temporarily. Note that the battery may drain quickly in cold
temperatures and lose enough power to switch off the phone within minutes. When you are
outdoors in cold temperatures, keep your phone warm.
Obey local regulations. Recycle when possible. Do not dispose as household waste.
Do not expose the battery to extremely low air pressure or extremely high temperature, such
as disposing of it in a fire, as that may cause the battery to explode or leak flammable liquid or
gas.
Do not dismantle, cut, crush, bend, puncture, or otherwise damage the battery in any way.
If a battery leaks, do not let the liquid touch the skin or eyes. If this happens, immediately
flush the affected areas with water or seek medical help. Do not modify, attempt to insert
foreign objects into the battery, or immerse or expose it to water or other liquids. Batteries
may explode if damaged.
Use the battery and charger for their intended purposes only. Improper use or use of
unapproved or incompatible batteries or chargers may present a risk of fire, explosion, or other
hazard, and may invalidate any approval or warranty. If you believe the battery or charger is
damaged, take it to a service centre or your phone dealer before continuing to use it. Never
use a damaged battery or charger. Only use the charger indoors. Do not charge your device
during a lightning storm. When charger is not included in the sales pack, charge your device
using the data cable (included) and a USB power adaptor (may be sold separately). You can
charge your device with third-party cables and power adaptors that are compliant with USB
2.0 or later and with applicable country regulations and international and regional safety
standards. Other adaptors may not meet applicable safety standards, and charging with such
adaptors could pose a risk of property loss or personal injury.
To unplug a charger or an accessory, hold and pull the plug, not the cord.
Additionally, the following applies if your device has a removable battery:
• Always switch the device off and unplug the charger before removing the battery.
• Accidental short-circuiting can happen when a metallic object touches the metal strips on
the battery. This may damage the battery or the other object.
SMALL CHILDREN
Your device and its accessories are not toys. They may contain small parts. Keep them out of
the reach of small children.
MEDICAL DEVICES
Operation of radio transmitting equipment, including wireless phones, may interfere with
inadequately shielded medical devices’ function. Consult a physician or the medical device’s
manufacturer to determine if it is adequately shielded from external radio energy.
