  • CES 805 DTMF, Page 1 INTRODUCTION Your new CES Model 805 Universal DTMF Encoder Microphone is designed to provide superior and trouble free service. The 805 microphone can be used to dial DTMF telephone numbers from a mobile radio, in conjunction with a base station equipped with a telephone interconnect system. Model 805 features include: n Automatic transmitter keying n Automatic microphone muting while transmitting DTMF n Reliable all metal keyboard switches n Audible sidetone for verifying proper tone entry n Universal audio input

  • CES 805 DTMF, Page 2 INSTALLATION The 805 Microphone requires 9VDC to 18VDC as a power source. If your 805 was shipped with a factory installed connector, then refer to the Application Note that is included, if any, for further instructions on modification of the radio to route this power source to the radio microphone connector jack. Some radio models have this power source already available and no modification is necessary. If your 805 was shipped with no connector installed, refer to Table 1. and wire a connector that mates with the

  • CES 805 DTMF, Page 3 INSTALLATION - continued Continuous Tone Coded Squelch The 805 provides CTCSS or other tone decoder monitor or disable as a logical function that goes low or to ground whenever the microphone is placed on a grounded hang up clip. For applications that require a logical low or ground when the microphone is removed from the grounded hang up clip, contact the CES Sales Department. When installing the 805 microphone, ensure that the microphone hang up clip is properly grounded to the vehicle chassis (add a ground wire if necessary) if using CTCSS or other Tone Decoder hang up logic in th

  • CES 805 DTMF, Page 4 INSTALLATION - continued DTMF TONE OUTPUT LEVEL With the service monitor set up as in the previous test: press a DTMF key on the 805 and adjust potentiometer RV1 (accessible through the upper opening) for 2/3 of the level that modulation limiting occurs as observed on the service monitor. For instance, if modulation limiting occurs at 5.0 KHZ, then set RV1 for a DTMF tone modulation of 3.3 KHz. If CTCSS tone is also being transmitted at the same time, set RV1 for a combined CTCSS + DTMF deviation of 4.0 KHz. Verify that the DTMF tones are not clipped or distort

  • CES 805 DTMF, Page 5 ADJUSTING TWIST The microphone generates two tones when any key on the keypad is depressed. The following table illustrates the row and column tones generated: Column Tones (Hz) 1209 1336 1477 Row 697 1 2 3 Tones 770 4 5 6 (Hz) 852 7 8 9 941 * 0 # The actual frequencies generated are: Keypad Location Reference Tone (Hz) Actual Tone Output (Hz) Percent Deviation Row Tone 1 697 699.1 +0.30 Row Tone 2 770 766.2 -0.49 Row Tone 3 852 847.4 -0.54 Row Tone 4 941 948.0 +0.74 Column Tone 1 1209 1331.7 +0.57 Column Tone 2 1336 1331.7 -0.32 Column Tone 3 1477 1471.9 -0.35 DTMF twist is the ratio between the levels of the colu
