OTHER OPERATIONS

Caution:

¡If you must stop playback or recording in the middle of a tape, be sure to press the STOP button first, then turn the power off. If the power is turned off in the middle of an operation, the cassette tape remains loaded, and it may be impossible to eject. In such a case, turn the power on, enter PLAY mode, then press STOP button, and then eject the tape.

¡The same caution as above applies in cases of power failure. To prevent damage, never attempt to force the removal of a cassette while the power is off.

ERASURE OF TAPE

When a program source is recorded onto a tape, the previously recorded sound is erased automatically, and replaced with the new recording. If you wish to erase a tape without recording, set the REC LEVEL control to the minimum (0) position or re- move the input source, and let the tape travel in the REC mode.

AUTO TAPE SELECTOR

This unit is equipped with auto tape selector which automati- cally sets the bias and equalizer level using the detection holes provided in the cassette shell. The bias and equalizer level is automatically set according to the type of cassette as follows. (See Figure 7)

AUTOMATIC BIAS ADJUST

With this feature, the microcomputer built into the PMD520 ad- justs the bias and record gain automatically so that the charac- teristics of the tape in use can be exhibited fully. (Refer to page 15 for more information)

1.Insert the cassette in the cassette holder of the well to be subjected to bias setting.

2.While holding down the REC button Press the REC MUTE button.

3.Ab will appear on the display followed by a number that will count down until the adjustment is complete.

4.If an Error occurs during this process, please refer to the next section.

5.When the bias has been set, the BIAS RESET indicator lights up.

6.To reset the bias to the factory setting, press the BIAS RE- SET button. The indicator is extinguished and the factory- set bias is recalled.

7.To return to the set bias, press the BIAS RESET button so the indicator lights up.

8.To change the bias setting, start the adjustment from the be- ginning.

Error Message

If a problem occurs during the AUTOMATIC BIAS routine, an Error message will appear on the display. Please refer to the following table.

Errors 2-5 are probably the result of a bad tape. Please rerun the AUTO BIAS program with a different tape.

TAPE STOP ALARM

When either Well A or B reaches the end of a tape, the PMD520 generates a buzzer sound to indicate it.

AUTO COUNTER RESET

When a cassette is removed from a cassette holder and an- other tape is inserted, the tape counter is reset automatically to "00:00".

TO PROTECT VALUABLE RECORDINGS

In the record mode, information previously recorded on the tape will automatically be erased. To prevent this from happening, use a small screwdriver to break out one or both safety tabs (See Figure 8). It is possible to restore the recording capability of either side of the cassette by covering the opening with clear adhesive tape (See Figure 9).

ENHANCED REMOTE CONTROL OPERATIONS

SIMULTANEOUS (PARALLEL) RECORDING

Check to insure that both wells are in REC PAUSE mode after pressing the A+B REC button on the front of the unit. The unit will start recording when either a PLAY or A+B command from the remote controller has been received. During the REC mode, the unit can be placed into a REC PAUSE mode by sending a PAUSE, A+B, or REC command from the remote controller and started again by a PLAY or A+B command from the remote controller. Pressing the STOP button on the front of the unit or sending a STOP command from the remote controller will cancel this operation.
