[. . . ] Press (DISPLAY/PTY) during FM reception until "PTY" appears. "--------" appears if the received station is not an RDS station, or if the RDS data is not received. Note You cannot use this function in some countries where no PTY (Programme Type selection) data is available. You can connect an optional DAB tuner to this unit. During radio reception, press (MENU), then press either side of (DISC/PRESET) repeatedly until "CT off" appears. DAB (Digital Audio Broadcasting) is a new multimedia broadcasting system that transmits audio programmes with a quality comparable to that of CDs. This is made possible by the use of a microcomputer in the DAB tuner which uses the radio signals sent from multiple aerials and multi-path signals (reflected radio waves) to boost the strength of the main signal. This makes DAB almost immune to radio interference even in a moving object such as a car. Each DAB station bundles radio programmes (services) into an ensemble which it then broadcasts. Each service contains one or more components. All ensembles, services, and components are identified by name, so you can access any of them without having to know their frequencies. The CT function may not work even though an RDS station is being received. ⷠThere might be a difference between the time set by the CT function and the actual time. Some services have not been sufficiently defined or are presently being tested. At present, such services are not supported by the optional DAB tuner unit XT100DAB. ⷠDAB programmes are broadcast in Band-III (174 to 240 MHz) and L-Band (1, 452 to 1, 492 MHz), with each band divided into channels (41 in Band-III and 23 in L-Band). Following procedure is available after presetting the service. " Press and hold either side of (SEEK) until "Seek +" or "Seek ­" appears. Tip There is another way to receive the preset service (preset on numbers 1 to 6). Press the number button ((1) to (6)) on which the desired service is stored. The unit will stop seeking when an ensemble is located. The unit will then automatically select the first service and display its name, and the display indicator will change from "Seek +"/"Seek ­" to the service name. [. . . ] The unit is installed at an angle of more than 60°. ⷠThe unit is not installed in a sturdy part of the car. An optional power amplifier is connected and you are not using the built-in amplifier. Cannot turn off the "--------" indication. [. . . ]
