¾ The devices are in the vicinity of a microwave that is in use.
¾ Other electromagnetic waves are generated in the location.
• Bluetooth communication uses the same frequency band (2.4 GHz) as wireless LAN (IEEE802.11b/g). If
the devices are used in the vicinity of equipment in which a wireless LAN unit is installed, the connection
status may become unstable due to the occurrence of radio-frequency interference. In this situation,
carry out the following countermeasures.
¾ When using Bluetooth communication to connect the printer and the mobile terminal, do so at a
distance of 10 m (32.8 ft.) or more away from the equipment in which a wireless LAN unit is installed.
¾ Bring the mobile terminal and the printer as close together as possible.
¾ If using Bluetooth communication within 10 m (32.8 ft.) of the equipment in which a wireless LAN
unit is installed, turn off the wireless LAN unit.
• The radio waves generated by Bluetooth communication may have an effect on the operation of electronic
medical equipment and similar devices. This may lead to accidents, so turn off Bluetooth communication
in the following locations.
¾ The vicinity of in-use hearing aids and pacemakers
¾ Hospitals
¾ The vicinity of automatic doors and fire alarms

• Roland DG Corp. accepts no responsibility for the leakage of information during a connection using
Bluetooth technology.
• The mobile terminal that you are using to connect to the printer must comply with Bluetooth standards
determined by the Bluetooth SIG and must be a certified device.
• Even if the mobile terminal complies with the Bluetooth standards outlined above, phenomena may
occur due to the characteristics and specifications of the device. Examples of these phenomena include
the inability to connect to the printer and the operation methods, display, and operations being different.
• Depending on the mobile terminal that you are connecting to the printer, it may take some time until
the Bluetooth connection can be established.
• The valid range of the connection may vary if obstacles are present between the printer and the mobile
terminal.
• While the Bluetooth connection is established, do not cover the mobile terminal with your hand or
anything else.
• Doing so may hinder the Bluetooth connection.
