Passkey Authentication A passkey is used to authenticate two Bluetooth devices that have not previously been connected to each other. This is to create a trusted relationship between them. You need to enter the same characters or numbers (passkey) for each device in the passkey-authentication process. The UPX-C300 system uses a 4-digit number as a passkey. After the same passkey is set for the devices, the authentication process for connection must be performed. Some Bluetooth devices require a new passkey entry when the valid authentication period of the devices is expired, the log file is deleted, or the security setting is changed. Passkey entry may be required, depending on the device, each time you intend to connect. Once authentication of devices has been confirmed in the UPX-C300 system, registration of each device connection is stored in a log file. After that, you can connect the devices without entering a passkey. If you wish to change the passkey, first delete the log file from the connected device, then register the devices again for re-authentication. This "Passkey" is also referred to as a "Bluetooth passkey" etc. "PIN" is also used with the same meaning. Changing the passkey settings You can change the passkey as required. On the UPX-C300 and separately available UP-DX100 Digital Photo Printer, the same passkey has been set at the factory. For communication security, it is recommended to change the passkey for your system. For details on changing settings, refer to the "Changing the Passkey" on page 52. Bluetooth Connection In the UPX-C300 system, the printer and the camera are factory preset so that the camera automatically searches for the printer for connection when both the printer and the camera are turned on.
