Fingerprint authentication is unavailable with
FOMA terminal connected to a PC etc.
When connecting FOMA terminal using a USB cable
to a device which requires grounding such as a
desktop PC, make sure that the device is grounded in
advance. If the connected device is not grounded,
fingerprint authentication may be disabled. In this
case, perform fingerprint authentication while
touching a metallic part (frame, external connector,
etc.) of the connected device or after disconnecting
FOMA terminal from the device.
● While operating and charging, FOMA terminal,
battery pack, etc. become hot.
While operating or charging, or if you use i-
α
ppli,
videophone call, 1Seg watching, etc. for a long time
while charging the battery, FOMA terminal, battery
pack and adapter (including battery charger) may
become hot. It is normal and continue to use it.
● The display has afterimages.
･ If the battery pack is removed from FOMA terminal
before the terminal power is turned off,
afterimages may remain. Remove the battery pack
after turning OFF the power.
･
If FOMA terminal is left open for a while with the
same screen displayed, afterimages of that screen
may remain even after changing the screen for a
certain operation.
●
The display has some dots always lit or unlit.
FOMA terminal displays are manufactured by taking
advantage of highly advanced technology but some
dots may be always or never lit. Note that, this shows
characteristics of liquid crystal displays and not
defects in FOMA terminals.
● Difference in lighting color and/or brightness
･ Note that, the phenomena below are caused by
characteristics of LEDs used for lighting, not
defects of FOMA terminal :
- The lighting color and/or brightness varies among FOMA
terminals or by LEDs.
- The actual lighting color seems to discord from the lighting
color name for some FOMA terminals.
- Though the lighting color name described indicates the
major light source color of the LED, the lighting may
appear in a different color because the light source settings
are delicately different among functions.
･
Check that the key lighting turns on in "Blueberry",
"Kiwi" and "Strawberry" by Keypad light, and the
light turns on in "Aqua", "Lime" and "Garnet" by
Light alert. If one or more of these colors do not
turn on, contact a sales outlet such as DOCOMO
Shop.
