Safety Precautions for Wireless connection In airplanes, follow the instructions from the airline. Turn off wireless devices during takeoff and landing according to the in-flight announcement. Do not use the product near medical equipment or in medical institutions. Radio waves may affect artificial cardiac pacemakers or other medical electrical equipment. Keep the product 22cm {8.66”} or more away from the location of an artificial cardiac pacemaker. Otherwise, radio waves may affect operation of the pacemaker. Do not use the product near automatic control equipment such as automatic doors and fire alarms. Doing so may cause malfunction due to radio waves, resulting in an accident.
Even after data transfer from the host computer is already finished, data may remain in the buffer in the printer. When wireless connection is terminated, data remaining in the buffer may be discarded. Before printing or terminating a wireless connection, make sure that the transmitted data has been printed completely by checking the print job status or by checking another way. For Bluetooth ® interface models, when the wireless connection is ended while the printer is offline, reconnection may not be possible. In such case, remove the cause of offline and recon- nect it.
For Bluetooth interface models, if you establish a radio connection between the host computer and the printer each time you start printing instead of maintaining the connection, it may take a while between the time you send a print job and the time that the printer actually starts printing. This happens because connecting the host computer and the printer requires some time. The time required for connection depends on the operating environment. WARNING 5
