•
The communication antenna of the handset is built into the
body and does not protrude. Signal sensitivity may be reduced
by touching/covering Internal Antenna area (page 1-3). Do not
cover this area by affixing stickers, or any other items. Doing so
may prevent you from making/receiving calls, sending/receiving
messages or accessing the Web.
•
When you replace the handset or send it for repair, messages
and other data stored in the handset cannot be transferred to
another handset.
•
Do not drop the USIM Card or subject it to excessive shock.
Doing so may cause a malfunction.
•
Do not bend the USIM Card or place a heavy object on it. Doing
so may cause a malfunction.
•
Do not allow the USIM Card to get wet or leave it in places of
high humidity. Doing so may cause a malfunction.
•
Do not use or leave the USIM Card in hot places such as near a
fire or heater. Doing so may cause a malfunction.
•
Avoid storing the USIM Card in direct sunlight or hot and humid
places. Failing to do so may cause a malfunction.
•
Keep the USIM Card out of infants' reach. Failing to do so may
result in the USIM Card being accidentally swallowed or cause
an injury.

Before using the USIM Card, read the instruction manual of the
USIM Card thoroughly to ensure safe and proper operation.
•
Do not put the handset into a bag or pocket without retracting
the TV Antenna. Doing so may apply excessive force on the TV
Antenna and result in damage.
OLED Display
•
The handset uses an OLED (Organic Light Emitting Diode)
display. The OLED display may develop dark areas or the colors
may change if the same image is displayed for a long time, if
the lighting is set brighter than necessary, or after it has been
used for an excessively long time. However, these are
characteristics of OLED displays and are not malfunctions.
•
The OLED display is made with extremely advanced technology,
but a very small number of pixels may remain dark or always
lighted. Also, depending on the angle of view, the display may
show a diagonal pattern of color, brightness distortion or color
change. However, these are caused by the way OLED displays
are made and are not malfunctions.
•
Leaving the OLED display exposed to direct sunlight may
damage it. Be careful when placing the handset outside or near
windows.
•
Icons at the top of Display turn off after the Display has been
on for a certain period of time.
