Please read these simple guidelines. Not following these guidelines may be dangerous or illegal.
Should a fault occur, a software tool is built into your device that will gather a fault log.
This tool gathers only data specific to the fault, such as signal strength, cell ID position in sudden call drop and
applications loaded. The log is used only to help determine the cause of the fault. These logs are encrypted and
can only be accessed by an authorized LG Repair centre should you need to return your device for repair.

your phone in hospitals as it may affect sensitive medical equipment.
• Do not handle the phone with wet hands while it is being charged. It may cause an electric shock and can
seriously damage your phone.

skin contact in the absence of adequate ventilation may result in discomfort or minor burns. Therefore, use
care when handling your phone during or immediately after operation.

• If your phone gets wet, immediately unplug it to dry off completely. Do not attempt to accelerate the drying
process with an external heating source, such as an oven, microwave or hair dryer.

Efficient phone operation
Electronics devices
All mobile phones may receive interference, which could affect performance.
• Do not use your mobile phone near medical equipment without requesting permission. Avoid placing the
phone over pacemakers, for example, in your breast pocket.
• Some hearing aids might be disturbed by mobile phones.
• Minor interference may affect TVs, radios, PCs etc.
• Use your phone in temperatures between 0ºC and 40ºC, if possible. Exposing your phone to extremely low or
high temperatures may result in damage, malfunction, or even explosion.
Road safety
Check the laws and regulations on the use of mobile phones in the area when you drive.
• Do not use a hand-held phone while driving.
• Give full attention to driving.
• Pull off the road and park before making or answering a call if driving conditions so require.
• RF energy may affect some electronic systems in your vehicle such as car stereos and safety equipment.
• When your vehicle is equipped with an air bag, do not obstruct with installed or portable wireless equipment. It
can cause the air bag to fail or cause serious injury due to improper performance.
• If you are listening to music whilst out and about, please ensure that the volume is at a reasonable level so
that you are aware of your surroundings. This is of particular importance when near roads.

Guidelines for safe and efficient use
Avoid damage to your hearing
To prevent possible hearing damage, do not listen at high volume levels for
long periods.
Damage to your hearing can occur if you are exposed to loud sound for long periods of time. We therefore
recommend that you do not turn on or off the handset close to your ear. We also recommend that music and call
volumes are set to a reasonable level.
• When using headphones, turn the volume down if you cannot hear the people speaking near you, or if the
person sitting next to you can hear what you are listening to.
NOTE: Excessive sound pressure from earphones and headphones can cause hearing
loss
Glass Parts
Some parts of your mobile device are made of glass. This glass could break if your mobile device is dropped on
a hard surface or receives a substantial impact. If the glass breaks, do not touch or attempt to remove it. Stop
using your mobile device until the glass is replaced by an authorised service provider.
Blasting area
Do not use the phone where blasting is in progress. Observe restrictions and follow any regulations or rules.
Potentially explosive atmospheres
• Do not use your phone at a refueling point.
• Do not use near fuel or chemicals.
• Do not transport or store flammable gas, liquid or explosives in the same compartment of your vehicle as your
mobile phone or accessories.
8
In aircraft
Wireless devices can cause interference in aircraft.
• Turn your mobile phone off before boarding any aircraft.
• Do not use it on the ground without permission from the crew.
Children
Keep the phone in a safe place out of the reach of small children. It includes small parts which may cause a
choking hazard if detached.
Emergency calls
Emergency calls may not be available on all mobile networks. Therefore you should never depend solely on your
phone for emergency calls. Check with your local service provider.
Battery information and care
• You do not need to completely discharge the battery before recharging. Unlike other battery systems, there is
no memory effect that could compromise the battery's performance.
• Use only LG batteries and chargers. LG chargers are designed to maximise the battery life.
• Do not disassemble or short-circuit the battery.
• Replace the battery when it no longer provides acceptable performance. The battery pack may be recharged
hundreds of times before it needs replacing.
• Recharge the battery if it has not been used for a long time to maximise usability.
• Do not expose the battery charger to direct sunlight or use it in high humidity, such as in the bathroom.
• Do not leave the battery in hot or cold places, as this may deteriorate battery performance.
• There is risk of explosion if the battery is replaced with an incorrect type.
• Dispose of used batteries according to the manufacturer's instructions. Please recycle when possible. Do not
dispose as household waste.
• If you need to replace the battery, take it to the nearest authorised LG Electronics service point or dealer for
assistance.

Guidelines for safe and efficient use
• Always unplug the charger from the wall socket after the phone is fully charged to save unnecessary power
consumption of the charger.
• Actual battery life will depend on network configuration, product settings, usage patterns, battery and
environmental conditions.
• Make sure that no sharp-edged items such as animal’s teeth or nails, come into contact with the battery. This
could cause a fire.
