Thank you for selecting the “FOMA P851i”.
Before or during use of the FOMA P851i, make sure that you read this manual and the separate manuals
such as for the battery pack thoroughly so that you can use the FOMA P851i correctly. If you feel any
inconvenience in reading the manual, contact the DoCoMo Information Center listed on the back page of
this manual.
The FOMA P851i is designed to be your close partner.
Treat it carefully at all times to ensure long-term performance.
Before using your FOMA phone
Because the FOMA phones use radio waves, they cannot be used in places where radio waves do not reach,
such as inside tunnels, underground, or in buildings; or the outside where radio waves are weak or out of the
FOMA service area. They may not be used in the high-rise buildings even when the antennas are
unobstructed. You may also experience interruption of calls even when using without moving while the radio
waves are strong enough for the three antennas to appear on the display.
Use the FOMA phone carefully to avoid disturbing other people when in public, or in crowded or quiet places.
Since the FOMA phones use radio waves as the medium of telecommunication, calls may be tapped by the
third party.
However, the W-CDMA system automatically supports tapping prevention, so your conversation will be
incomprehensible to the third party.
The FOMA phones change your voice into digital signals and send them to the other party. In places where the
radio waves are weak, the digital signals may not be converted correctly, and in such a case, the voice heard
may sound different from the actual original voice.
It is recommended that you take separate notes of the information stored in the FOMA phone and keep such
notes in a safe place. DoCoMo cannot be held responsible in any way for the loss of data stored in the phone.
The user hereby agrees that the user shall be solely responsible for the result of the use of SSL. Neither
DoCoMo nor the certifier as listed herein makes any representation and warranty as for the security in the use
of SSL. In the event that the user shall sustain damage or loss due to the use of SSL, neither DoCoMo nor the
certifier shall be responsible for any such damage or loss.
