2) Auto sleep function at iOS mode [Bluetooth(iAP)]
At iOS mode [Bluetooth(iAP)], 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 specifications. Therefore, it is impossible to use the Auto sleep function when the Communi-
cation mode of the printer is set to iOS mode [Bluetooth(iAP)].

Press and hold the MODE button and the FEED button for at least five seconds until ERROR LED flashes
five times.
Continuously hold down the MODE button and the FEED button even until the buzzer sounds twice.
The Bluetooth communication mode switches.
