Performing Operations from the Dedicated Mobile Operation Application

Important Notes on Using the Operation Application

Number of printers that you can connect to
You can only connect to one printer from a mobile terminal on which the operation application has been installed.
You can register multiple printers, but you cannot connect to multiple printers at the same time.
No pairing is required
Generally speaking, "pairing" is required to establish a Bluetooth connection. With the operation application, no
"pairing" is required. After starting the operation application, follow the instructions on the screen to connect to
the printer.
Perform operations from a position where you can see the printer.
To enable immediate handling of unexpected printer operations, perform operation application operations from a
position where you can see the printer.
Important notes on Bluetooth communication
• With Bluetooth wireless technology, it is possible to establish a connection between devices separated by ap-
proximately 10 m (32.8 ft.). However, the valid range of the connection may vary depending on the presence
of obstacles (such as people, metal, and walls) and the status of the radio waves.
• The communication status of the Bluetooth connection may become unstable if:
• A wireless LAN is in place in the location.
• The devices are in the vicinity of a microwave that is in use.
• 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 de-
vices 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 follow-
ing countermeasures.
• 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.
• Bring the mobile terminal and the printer as close together as possible.
• 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.
• The vicinity of in-use hearing aids and pacemakers
• Hospitals
• The vicinity of automatic doors and fire alarms
P. 213「Turning on Bluetooth Communication」
• Using Bluetooth communication in the vicinity of TVs or radios may lead to noise in the image or audio.
• Roland DG Corporation 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 deter-
mined 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 Blue-
tooth connection can be established.
