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.

•Keep the metal contacts of the battery clean.

•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.

•Always unplug the charger from the wall socket after the phone is fully charged to save unnecessary power consumption of the charger.

Precautions

•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.

Adapter

•Charge the battery pack in a place with an ambient temperature between 0 °C and 45 °C.

•Do not charge the battery pack in the following areas.

-In areas of excessive humidity, dust or vibration

-Near land-line phones, TVs or radios

•It is normal for the adapters to become warm while using or charging the terminal. You can continue to use it.

•Use the DC adapter only when the car engine is running.

-Otherwise, the car battery may be exhausted.

•Do not give a strong impact to the adapter. Also, do not deform the charging terminals.

Malfunction may result.

Micro USIM

•Do not put excessive force on the Micro USIM when inserting or removing it into this terminal.

•Do not insert and use the Micro USIM with another IC card reader/writer. Please note that you are wholly liable for any damage or malfunction as a result of such action.

•Always keep the IC portion of the Micro USIM clean.

•Clean the Micro USIM with a soft, dry cloth (Lens cleaning cloth).

•Be sure to keep a separate note of the information registered to this terminal.

Claro assumes no responsibility for the loss of any of your data.

•Visit service center to return the expended Micro USIM for the environmental purpose.

Using Micro USIM

A Micro USIM is an IC card that stores personal information such as your phone number. Without the Micro USIM installed in this terminal, you cannot use data communication. For details on handling the Micro USIM, refer to the Micro USIM manual.

Only the Micro USIM can be used in this terminal.

Inserting the Micro USIM

When inserting the Micro USIM, hold this terminal with both hands.

•Turn the power off and remove the battery pack before attaching the Micro USIM.

1With the IC chip side down, insert a Micro USIM under the Micro USIM slot guide in the direction of arrow.

Removing the Micro USIM

When removing the Micro USIM, hold this terminal with both hands.

•Turn the power off and remove the battery pack before removing the Micro USIM.

1Slide the Micro USIM in the direction of arrow to remove.

NOTE

•Do not lose the removed Micro USIM.

•Check both sides of the Micro USIM.

•Be careful not to touch or scratch the

Micro USIM IC.

•Inserting a Micro USIM in the reverse direction may cause malfunction.

•Inserting or removing the Micro USIM with an excessive force

Security Codes

A Micro USIM has PIN1 (Personal Identification Number) code.

The PIN1 code is a 4 to 8-digit security code to be entered every time this terminal is turned on for user verification to prevent any unauthorized use by others.

Before Using this Terminal

If your Micro USIM is set to require a PIN1 code, data communication cannot be performed until the PIN1 code is entered.

Use the Micro USIM before verifying the PIN1 code, or set the Micro USIM not to verify the PIN1 code in advance.

•Changing PIN1 Code

You can change the PIN1 code to any number. To prevent any unauthorized use by third parties, change it to your original number.

If you improperly enter the PIN1 code for 3 times in a row, further entry is locked automatically (PIN1 Lock), so be sure to keep a separate note of the numbers you set.

-“Changing the Security Code (Modify PIN code)”

•Unblocking PIN Code

The unblocking PIN code is the number in 8 digits used to unblock the PIN1 code. Details are written in the application of the contract (a duplicate copy) during

the subscription. You cannot change the unblocking PIN code.

If you improperly enter the unblocking PIN code for 10 times in a row, the Micro USIM locks automatically.

Caution

•Do not set PIN1 code to numbers that can be easily guessed, such as “birth date”, “part of your phone number”, “numbers from address or room number”, “1111”, “1234”, etc. Also, make a note of your PIN1 code and keep it well.

•Keep your PIN1 code away from being known by other people. Claro assumes no responsibility for the loss of any of your data results from abuse of PIN1 code.

Charging

Battery pack life

• The battery pack is a consumable item. The usable time decreases every time the battery pack is recharged.

• When the usable time after each recharging shortens by approximately half compared to a new battery pack, it is recommended that the battery pack be replaced with a new one as soon as possible. The battery pack may swell as the battery life is near its end depending on the battery pack condition,

but it is not a malfunction.

Before Using this Terminal

•If you make communication while the battery pack is being charged, the battery life may be shortened.

Charging

•To use an AC adapter overseas, the compatible conversion plug adapter is required. Do not charge the battery pack with a transformer designed for overseas trips.

•To charge the battery pack with the AC or DC adapter, make sure that the battery pack is inserted into this terminal.

•Plug or unplug the connector slowly and securely avoiding excessive force.

•If you start charging the fully drained battery pack, this terminal may not be turned on for a while.

•If you make communication while charging, the inside of this terminal may become

hot and charging may stop. In this case, end the functions in use and wait until this terminal becomes cool down, and then try charging again.

•Depending on the usage condition, charging

may stop before the battery level becomes 100%. In this case, remove the battery pack and attach it again to continue charging.

•Do not remove the battery pack while charging. If the battery pack is removed, the power does not correctly turn on or the battery is not correctly charged. In that case, remove the battery pack and all cables from this terminal, and reconnect them.

Approximate battery pack usage & charging time

The usage time may vary depending on the operating environment and the battery pack deterioration.

•Continuous communication time is the approximate usage time when you can normally send and receive radio waves.

•Continuous stand-by time is approximate usage time when moving with normal radio wave reception level.

•Communication time or operating time may be reduced by half depending on the battery level, set functions,

operating environment such as ambient temperature, or radio wave reception level (poor or weak radio wave reception level).

•Depending on network conditions in the country you stay, usage time may become shorter than the described values.

•The estimated charging time is the duration of time to charge a fully drained battery pack with this terminal turned off. The charging time becomes longer with this terminal turned on.

Turning Power On/Off

Turning Power On

1When this terminal is turned off, hold down the power button for over 2 seconds.

Before Using this Terminal

Available Communications

Basic Usage

You can perform data communication at a speed of up to 100Mbps* for receiving data and up to 50Mbps* for sending data by connecting up to 10 Wi-Fi devices compatible with wireless LAN function.

*Communication speed is theoretical values when sending and receiving data which does not show the actual ones. The actual communication speed depends on communication environment and network congestion.
