Take care of your device
Handle your device, battery, charger and accessories with care. The following suggestions help you keep
your device operational.
• Keep the device dry. Precipitation, humidity, and all types of liquids or moisture can contain minerals that
corrode electronic circuits. If your device gets wet, remove the battery if possible, and let the device dry.
• Do not use or store the device in dusty or dirty areas.
• Do not store the device in high temperatures. High temperatures may damage the device or battery.
• Do not store the device in cold temperatures. When the device warms to its normal temperature, moisture
can form inside the device and damage it.
• Do not open the device other than as instructed in the user guide.
• Unauthorized modifications may damage the device and violate regulations governing radio devices.
• Do not drop, knock, or shake the device or the battery. Rough handling can break it.
• Only use a soft, clean, dry cloth to clean the surface of the device.
• Do not paint the device. Paint can prevent proper operation.
• Keep the device away from magnets or magnetic fields.
• To keep your important data safe, store it in at least two separate places, such as your device, memory
card, or computer, or write down important info.
During extended operation, the device may feel warm. In most cases, this is normal. To avoid getting too
warm, the device may automatically slow down, close apps, switch off charging, and if necessary, switch itself
off. If the device is not working properly, take it to the nearest authorized service facility.
Recycle
Always return your used electronic products, batteries, and packaging materials to dedicated
collection points. This way you help prevent uncontrolled waste disposal and promote the recycling of
materials. Electrical and electronic products contain a lot of valuable materials, including metals
(such as copper, aluminum, steel, and magnesium) and precious metals (such as gold, silver, and
palladium). All materials of the device can be recovered as materials and energy.
Crossed-out wheeled bin symbol
The crossed-out wheeled bin symbol on your product, battery, literature, or packaging reminds you
that all electrical and electronic products and batteries must be taken to separate collection at the end
of their working life. Do not dispose of these products as unsorted municipal waste: take them for
recycling. For info on your nearest recycling point, check with your local waste authority.
About Digital Rights Management
When using this device, obey all laws and respect local customs, privacy and legitimate rights of others,
including copyrights. Copyright protection may prevent you from copying, modifying, or transferring photos,
music, and other content.
Battery and charger info
Use your device only with an original HE402 rechargeable battery. The battery can be charged and discharged
hundreds of times, but it will eventually wear out. When the talk and standby times are noticeably shorter
than normal, replace the battery.
Chargers
Charge your device with the DSA-5PF18-05 FUS 050100 charger. Some of the accessories mentioned in this
user guide, such as charger, headset, or data cable, may be sold separately.
Battery and charger safety
Once charging of your device is complete, unplug the charger from the device and electrical outlet. Please
note that continuous charging should not exceed 12 hours. If left unused, a fully charged battery will lose
its charge over time.
Always keep the battery between 15°C and 25°C (59°F and 77°F) for optimal performance. Extreme
temperatures reduce the capacity and lifetime of the battery. A device with a hot or cold battery may not work
temporarily. Obey local regulations. Recycle when possible. Do not dispose as household waste.
Do not expose the battery to extremely low air pressure or leave it to extremely high temperature, for example
dispose 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 liquid touch 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 center 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. 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.
Implanted medical devices
To avoid potential interference, manufacturers of implanted medical devices (such as cardiac pacemakers,
insulin pumps, and neurostimulators) recommend a minimum separation of 15.3 centimeters (6 inches)
between a wireless device and the medical device. Persons who have such devices should:
• Always keep the wireless device more than 15.3 centimeters (6 inches) from the medical device.
• Not carry the wireless device in a breast pocket.
• Hold the wireless device to the ear opposite the medical device.
• Switch the wireless device off if there is any reason to suspect that interference is taking place.
• Follow the manufacturer directions for the implanted medical device.
If you have any questions about using your wireless device with an implanted medical device, consult your
health care provider.
