[9/11]
Use only the included stylus pen when operating the tablet
with an equipment.
Using an equipment other than the included stylus pen may damage
or contaminate the display.
Do not use the stylus pen to operate other devices.
May damage the other devices or result in a malfunction.
The tablet supports the security function that meets the
Bluetooth specification for security during communication
using Bluetooth functions. However, the security may not
be sufficient depending on the configuration etc. Take care
of the security while making communication using
Bluetooth function.
Even if any leak of data or information occurs while making
communication using Bluetooth function, DOCOMO shall
not be liable for any loss of content.
Radio frequencies
In the home screen, [
R ] / [Settings] / [Device info] /
[Authentication] to confirm the radio frequencies the Bluetooth
function of the tablet uses. The followings are the descriptions:
① 2.4: This radio equipment uses the 2400 MHz band.
② FH: The modulation system is the FH-SS system.
③ 1: The estimated coverage distance is 10 m or less.
④ XX: Another modulation system is used.
⑤ 4: The estimated coverage distance is 40 m or less.
⑥ : All radio frequencies between 2400 MHz and 2483.5
MHz are used and the frequencies for mobile object identifiers
shall not be avoided.
Cautions on using Bluetooth devices
Bluetooth operates at radio frequencies assigned to the
in-house radio stations for a mobile object identifier that have
to be licensed and is used in production lines of a factory,
specific unlicensed low power radio stations, and amateur
radio stations (hereafter, referred to as “another radio station”)
in addition to industrial, scientific and medical devices or home
electric appliances such as microwave ovens.
1. Before using the tablet, make sure that “another radio
station” is not operating nearby.
2. If radio interference between the tablet and “another
radio station” occurs, avoid interference by moving
immediately to another place or “turning off the power”.
3. Contact the number listed in “General Inquiries” on the
last page for further details.
Wireless LAN (WLAN) uses radio waves to communicate
information. Therefore, it has an advantage of freely
connecting to the LAN within the service area. On the other
hand, if security setting is not set, it is possible for a
malicious third party to intercept the communication
contents or hack. It is recommended to set security setting
at your own risk and judgement.
Wireless LAN
Do not use wireless LAN near magnetic devices such as electric
appliances or AV/OA devices or in radio waves.
･ Magnetism or radio waves may increase noises or disable
communications (especially when using a microwave oven).
･ When used near TV, radio, etc., reception interference may occur
or channels on the TV screen may be disturbed.
･ If there are multiple wireless LAN access points nearby and the
same channel is used, search may not work correctly.
Radio frequencies
In the home screen, [R]/[Settings]/[Device info]/
[Authentication] to confirm the radio frequencies the
WLAN-installed devices use. The followings are the
descriptions:
① 2.4: This radio equipment uses the 2400 MHz band.
② DS: The modulation system is the DS-SS system.
③ OF: The modulation system is the OFDM system.
④ 4: The estimated coverage distance is 40 m or less.
⑤ : All radio frequencies between 2400 MHz
and 2483.5 MHz are used and the frequencies for mobile object
identifiers shall be avoided.
Available channels for the tablet’s wireless LAN are between 1 and
13. Note that other channel access points cannot be connected.
Available channels may vary depending on the country.
For use in an aircraft, contact the airline beforehand.
Cautions on using 2.4 GHz devices
WLAN-installed devices operate at radio frequencies
assigned to the in-house radio stations for a mobile object
identifier (radio stations requiring a license) used in
production lines of a factory, specific unlicensed low power
radio stations (radio stations requiring no license), and
amateur radio stations (radio stations requiring a license) in
addition to industrial, scientific and medical devices or
home electric appliances such as microwave ovens.
1. Before using this device, make sure that the in-house
radio stations for a mobile object identifier, specific
unlicensed low power radio stations and amateur radio
stations are not operating nearby.
2.
If the device causes harmful radio interference to the
in-house radio stations for a mobile object identifier,
immediately change the radio frequency or stop use, and
contact the number listed in “General Inquiries” on the last
page for crosstalk avoidance, etc. (e.g. partition setup).
3. If the device causes radio interference to specific unlicensed
low power radio stations for a mobile object identifier or
amateur radio stations, contact the number listed in
“General Inquiries” on the last page for further details.
Cautions on using 5 GHz devices
In the 5 GHz frequency band, three bands of 5.2 GHz/5.3
GHz/5.6 GHz band (W52/W53/W56) are available.
･ W52 (5.2 GHz band/36, 40, 44, 48 ch)
･ W53 (5.3 GHz band/52, 56, 60, 64 ch)
･ W56 (5.6 GHz band/100, 104, 108, 112, 116, 120, 124, 128,
132, 136, 140 ch)
Using 5.2 GHz/5.3 GHz band wireless LAN (W52/W53)
outdoors is prohibited by the Radio Law.
Never use the tablet that is modified. Using a modified
device violates the Radio Law and/or the
Telecommunications Business Law.
The tablet has acquired the certification of conformity with technical
regulations for the specified radio station based on the Radio Law and
authentication of conformity with technical regulations for the tablet
based on the Telecommunications Business Law, and the “Technical
Conformity Mark ” can be displayed on the electronic nameplate of
the tablet as a proof. You can see it by operating as follows.
In the home screen, [R]/[Settings]/[Device info]/[Authentication]
If the screws of the tablet are removed and a modification is given to
the inside, the certification of conformity with technical regulations etc.
will become invalid. Never use the tablet without the valid certification
etc. Doing so violates the Radio Law and/or the Telecommunications
Business Law.
