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.
5
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.
6
•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.
•Do not scratch, touch carelessly or short
circuit the IC portion.
Data loss or malfunction may result.

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.

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.
15
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.
16
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
•DonotsetPIN1codetonumbersthatcan
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.
•KeepyourPIN1codeawayfrombeing
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.
23
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.
24
•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.

•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.
