TUNING OPERATION Preset tuning 4, 2 This unit can store station frequencies selected by tuning operation. With this function, you can select any desired station by only calling the corresponding preset station number. Up to 40 stations (8 stations x 5 groups) can be stored.
Automatic preset tuning 1 You can also make use of an automatic preset tuning function. By this function, this unit performs automatic tuning and stores stations with strong signals sequentially. Up to 40 stations are stored automatically in the same way as in the manual preset tuning method on the previous page.
RECEIVING RDS STATIONS RDS (Radio Data System) is a data transmission system gradually being introduced by FM stations in many countries. Stations using this system transmit an inaudible stream of data in addition to the normal radio signal. RDS data contains various information, such as PI (Program Identification), PS (Program Service name), PTY (Program Type), RT (Radio Text), CT (Clock Time), etc. RDS function is carried out among the network stations.
➀ Changing the RDS modes When an RDS station is received, “PS”, “PTY”, “RT” and/or “CT” that correspond to the RDS data services employed by the station light up on the display. By pressing the FREQ PS/PTY/RT/CT selector button once or more, you can change the display mode among the RDS modes employed by the received station in the order shown below. (The RDS mode not employed by the station cannot be selected.
RECEIVING RDS STATIONS • There may be a case that RDS data reception is not possible due to poor reception conditions. If so, press the AUTO/MAN’L button so that “AUTO” goes off from the display. Though the reception mode is changed to monaural by this operation, when you change the display to an RDS mode, RDS data may be displayed.
Other functions which make use of RDS data service This unit has the following functions which make use of RDS data service. These are originally in operation [ON]. However, you can cancel these functions [OFF], if so desired. 1 EEK S PTY 2 ➀ ON (OFF) CT > CLOCK This unit corrects the time of the built-in clock automatically by synchronizing it with the CT data on the RDS station being received.
TAPE DECK OPERATION General information • • • • • • • Detection hole • Tab Do not use C-120 tapes or poor-quality tapes, since they can cause malfunctions. Before loading a tape into the cassette compartment, tighten the tape slack with a pen or pencil. Tapes have removable tabs which prevent accidental recording or erasing from taking place. Removing the tab on the top left protects the side facing you from erasure. Cover the tab holes with adhesive tape to erase or record again.
