Telephone number decipherment device
DEC-1

Outline
  • The both sides of a pulse formula and multi-tone formula are also possible for a decipherment display.
  • If the tape recorded by the automatic recorder(KKCR-360) with the transmitter for a telephone is played and it inputs into a decipherment device, the sent telephone number (partner first-move number) will be displayed. In the case of an arrival-of-the-mail telephone, it is impossible.
Directions
  • The output code terminal of attached AC adapter is put in the power supply supply terminal (display of DC9-12V) of a main part. Next, an attached code is put in the earphone terminal of the tape recorder to reproduce, and another side of the code is put in the signal input terminal (SIGNAL INPUT) of a decipherment device. A surface monitor terminal (EAR) puts an earphone with the object for level surveillance.
  • AC adapter is put in AC wall socket. And a power supply switch (POWER) is turned ON. Then, since it is displayed on a display part some <thing> or other, a reset button (DISPAY&RESET) is pushed, and it is a display. It is made 0. The number currently recorded sets up a surface switch by the pulse formula or the tone formula. A slide switch will be changed, if it is a pulse formula (DIAL) and it is a tone formula (TONE).
  • Play a tape, checking by the earphone. Sound called a two can be heard the start of recording. Next, it changes to the sound of "Basabasa" or "pippopa" The sound is the signal with which the telephone number was recorded. Sound called "pippopa" at a pulse formula (DIAL) in sound called "Basabasa" is a tone formula (TONE). for decoding -- the signal sound -- a tape is rewound until very recently and a tape is played Supposing some numbers other than zero are displayed on the number display part, just before a signal portion is reproduced, a reset button will be pushed and a display will be set to 0. Since the reset button is a touch formula, it operates only by pushing for a moment.
  • When the level of the signal inputted into this device is reproduced with an automatic recorder (KKCR-360) and it inputs, the output level of a tape recorder is set up so that about five place may become the optimum in the position of volume. It is other, and when reproducing and inputting, in the case of a pulse formula, it adjusts so that the brightness of blink of a red lamp may become the same. Please reproduce and be sure to input with the recorded automatic recorder in the case of a tone formula. It may not be detected if the speed of the tape recorder itself is delicately different.
  • The number which was mistaken when noise was mixed and some were also especially a pulse formula is displayed on the signal inputted into a decipherment device. When a number decipherment is required, carefully, the place with the sufficient receiving sensitivity without noise is looked for, and it is made to install especially.
