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
Windows 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
without 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 o Bluetooth on your iOS device, or delete the device.

2) Auto sleep function at iOS mode [Bluetooth(Auto)]
At iOS mode [Bluetooth(Auto)], set the Auto sleep mode to “NO USE” or Auto OFF mode.
When the printer wakes from the sleep mode, it cannot connect with the iOS device properly due to
the iOS specications. Therefore, it is impossible to use the Auto sleep function when the Communi-
cation mode of the printer is set to iOS mode [Bluetooth(Auto)].
