The valid range for a Bluetooth connection is approximately 10
m. Bring the printer and the mobile terminal on which Mobile
Panel has been installed as close together as possible.
If obstacles (such as people, metal, and walls) are present between
the printer and the mobile terminal, the Bluetooth connection
may be unstable. Use Mobile Panel from a location where there
are no obstacles between the printer and the mobile terminal.
Check the status of the Bluetooth connection of the mobile ter-
minal on which Mobile Panel has been installed. For the usage
method of your mobile terminal, refer to its user's manual.
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.
