■ Do not give a strong impact to the adapter. Also, do not deform
the charging jack.
May cause malfunction.
nanoUIM card precautions
■ Do not use excessive force to attach/remove nanoUIM card.
■ Note that DOCOMO assumes no responsibility for malfunctions
occurring as the result of inserting and using a nanoUIM card with
another IC card reader/writer.
■ Clean the IC area occasionally to use it in a clean state.
If you use the IC area when it is soiled, the terminal may not function
correctly.
■ Clean nanoUIM card with a soft, dry cloth (such as a cloth for
eyeglasses).
■ Make a backup to microSD cards, PC, or cloud or maintain a
separate record of the data you saved in nanoUIM card.
Note that DOCOMO assumes no responsibility for any loss of saved
data.
■ To preserve the environment, bring the old nanoUIM card to a
sales outlet such as docomo Shop.
■ Do not carelessly damage, contact, or short-circuit an IC.
May cause data loss or malfunction.
■ Do not drop nanoUIM card or subject it to shocks.
May cause malfunction.
■ Do not bend nanoUIM card or place heavy objects on it.
May cause malfunction.
■ Do not attach nanoUIM card to the terminal with a label or sticker
put on nanoUIM card.
May cause malfunction.
Bluetooth function precautions
■ To secure the Bluetooth communication security, the terminal
supports the security function compliant with Bluetooth standards,
but the security may not be sufficient depending on the settings.
Be aware of the communication using the Bluetooth function.
■ Note that DOCOMO is not responsible for data or information leak
when making data communications using Bluetooth.
• Frequency band
The frequency band used by the terminal's Bluetooth function/Wi-Fi
function is indicated on the battery storage section.
2.4 FH1 / DS4 / OF4 / XX8
2.4 : This radio equipment uses the 2400 MHz band.
FH/DS/OF/ : Modulation scheme is FH-SS, DS-SS, OFDM or other
XX scheme.
1 : The estimated interference distance is 10 m or less.
4 : The estimated interference distance is 40 m or less.
8 : The estimated interference distance is 80 m or less.
: The full band between 2400 MHz and 2483.5 MHz
is used and the band of the mobile identification
device is unavoidable.
Available channels vary by the country.
For use in an aircraft, contact the airline beforehand.
• Cautions on using Bluetooth devices
The operating frequency band of the terminal is used by industrial,
scientific, consumer and medical equipment including microwave
ovens, premises radio stations for identifying mobile units used in
the manufacturing lines of plants (radio stations requiring a license),
specified low power radio stations (radio stations requiring no license)
and amateur radio stations (hereinafter referred to as "another station").
1. Before using the terminal, confirm that "another station" is not being
operated nearby.
2. In the event of the terminal causing harmful radio wave interference
with "another station", promptly change the operating frequency or
stop radio wave emission by "turning off the power", etc.
3. If you have further questions, contact "General Inquiries" provided on
the last page of this manual.
