Using Disaster Message Board
Disaster Message Board is a service to enable customers in disaster
areas to register their safety information via LTE NET when large-scale
disasters, such as an earthquake whose Japan seismic scale is
approximately 6-lower or more, occur. The registered safety
information can be checked by customers using au phones, and also
from other-brand cell phones, PCs, etc.
For details, refer to "Disaster Message Board Service" on the au
homepage.

be changed.
* When you receive Earthquake Early Warning, you will be notified by
the alarm tone, voice ("地震です" (Jishin-desu) ("Earthquake!"))
meaning that an earthquake has occurred and the vibrator.
* When you receive Tsunami Warning, you will be notified by the alarm
tone, voice ("津波です" (Tsunami-desu) ("Tsunami!")) meaning that a
Tsunami is approaching and the vibrator.
◎The alarm tone does not ring if Emergency Rapid Mail is received
during a call.
◎Earthquake Early Warning notifies areas where a strong shaking
(Japan seismic scale 4 or more) is expected when an earthquake
whose maximum Japan seismic scale is predicted of 5-lower or
more has been detected.
◎This service detects an earthquake (P-wave, preliminary tremors)
near the seismic center immediately after the earthquake occurs
and automatically calculates its location, scale and predicted
strength of the shaking. After that, you will be notified of the
earthquake as soon as possible within a few seconds to dozens
of seconds before a strong shaking from the earthquake (S-wave,
principal shock) occurs.
◎In the vicinity of the seismic center, a strong shaking may reach
you before Earthquake Early Warning.
◎Tsunami Warning notifies areas including target sea coasts of
Major Tsunami Warning and Tsunami Warning provided by the
Japan Meteorological Agency.
◎Disaster and Evacuation Information notifies information related
to the safety of citizens, such as evacuation advisories,
evacuation orders or various alarms delivered by the national
government or the local governments.
◎This service is available only in Japan (Not available overseas).

basements) or the signal is weak, even within the service area.
◎Emergency Rapid Mail which failed to be received will not be
able to be received again.
◎The Earthquake Early Warning distribution system provided by
this service is different from that provided by TV, radio and other
communication media and thus the arriving time of Earthquake

Safety Precautions
Do not use with the back cover removed. Do not leave or
store in that manner. Doing so may allow dust or other
foreign matter to enter and cause a fault.
Do not place near corrosive chemicals or in places where
corrosive gas is generated. Doing so might cause a fault
or loss of internal data.
Stop use if there is smoke, abnormal odor or noise,
excessive overheating, or other abnormalities. During
charging, disconnect the specified charger (sold
separately) from the power outlet, make sure that the
product is not overheating before turning the power off,
remove the battery pack and contact an au shop or Keitai
Guarantee Service Center. Also, if you have dropped or
damaged the product, do not continue to use it in that
state, and contact an au shop or Keitai Guarantee Service
Center.
When inserting an earphone, etc. into the product, adjust
the volume to the proper level by increasing it gradually.
Suddenly turning the sound on with the volume set too
high, too loud a volume or using the earphone continuously
for a long period of time might adversely affect your ears.
Also, raising the volume too high might prevent you from
hearing sounds around you, which might in turn lead to a
traffic accident at a railroad crossing or pedestrian
crossing.
When using handsfree call, take care to keep the speaker
at a safe distance from your ears, as the speaker volume
may be too loud.

become stuck to the main unit, and cause unexpected
injury. Before using the product, always make sure there is
nothing stuck to the speaker or other part.
Do not put the product directly on sand at a beach, etc.
Sand or other small particles might get inside the
microphone, speaker causing the volume to drop. If sand

immediately and seek medical attention. Wipe away
battery fluid on the product without directly touching fluid.
The battery pack is a consumable item. If the performance
of a battery pack does not recover (e.g. the usable time
after each charge has become extremely short), the
battery pack is at the end of service life, so stop use and
buy a new one of the specified type. Failure to do so might
cause overheating, ignition, rupture or leakage. Note that
the length of service life varies depending on the usage
condition, etc.
Be careful not to let a pet bite the battery pack.
Letting it do so might cause leakage, overheating, rupture,
ignition, fire, injury, etc.
