1) Communication mode
It is possible to change the communication mode setting between Bluetooth and serial. Please see
below for details to select the proper communication mode for your application.
RS-232C:
The display shows [UART Mode]. At the RS-232C mode, the printer can communicate with a
device using the serial communication cable supplied with the printer. When you connect
the serial cable, the printer is automatically switched to serial communication from Bluetooth
communication.
Bluetooth(Mac) :
[Bluetooth(Mac)] is printed when a self test is executed.
At the Bluetooth(Mac) mode, the printer can communicate with Mac, Android device and Win-
dows over Bluetooth.
Bluetooth (Auto) :
[Bluetooth (Auto)] is printed when a self test is executed.
When using the printer with an iOS, Android, or Windows device, you can use Bluetooth with-
out manually switching the Bluetooth mode.
Note: If you used an iOS device before an Android device, the auto connection function for
iOS prevents the Android device from connecting to the printer.
Make sure to turn off Bluetooth on your iOS device, or delete the device.

communication
mode [Bluetooth(Auto)]

to)].
