Description

From the listing uploaded by “appupdater”.

“QRsetup” lets you easily connect your Android device to the AirStation. Just scan the AirStation’s QR code to automatically connect your Android device to the AirStation. Compatible Devices: Devices with a rear camera that has an autofocus function. Notes: • Not all AirStation models are compatible with QRsetup. Only AirStation models with a QR code on the sticker or setup card are compatible with QRsetup. • If an error occurs while scanning the QR code, try the following: ◦ Reboot your Android device. ◦ Move your Android device closer to the AirStation and try again. ◦ Check the AirStation’s operation mode. Make sure the switch is on either Auto or Router mode. ◦ Change the AirStation’s wireless channel. ◦ If there are two QR codes on the setup card, try scanning the other QR code. ◦ Initialize the AirStation (all settings will be deleted). • If you cannot connect your Android device to the AirStation when using 2.4 GHz, your Android device may not be compatible with wireless channels 12 and 13. In such a case, set the AirStation’s wireless channel to one between 1–11 from the AirStation’s Settings. • If you cannot connect your Android device to the AirStation when using 5 GHz, your Android device may not be compatible with wireless channels 52–140. In such a case, set the AirStation’s wireless channel to one between 36–48 from the AirStation’s Settings. • QRsetup reads the AirStation’s factory default security settings from the QR code. If you change any security setting of AirStation, you cannot connect your Android devices to the AirStation using QRsetup. • On a device running Android 6.0 or later, QRsetup cannot work due to OS restrictions unless permission to access the camera and location services is granted. Follow the displayed directions and configure the settings. (QRsetup does not collect any location data or data obtained by the camera.) • QR Code is a registered trademark of DENSO WAVE INCORPORATED.
