Model 710 Manual GENERAL DESCRIPTION The CES Model 710 DTMF Encoder Microphone is engineered specifically for mobile radio applications. Whether used on SMR trunked systems, conventional telephone interconnected shared mobile radio systems, or in dedicated single-user radio systems, your new 710 series microphone will enhance the utility of your mobile communications.
INSTALLATION Your CES Model 710 DTMF Encoder microphone requires filtered +10 to +15 VDC to power it's audible sidetone, keypad illumination, and microprocessor. The 710 is available with factory installed mating connectors for many popular transceivers. The connectors are configured to receive the required operating power at the radio microphone jack. Some transceivers may not already have a provided voltage source output available at the microphone jack.
LEVEL SETTING AND INTERFACE ADJUSTMENTS Jumper JP1 - Audio Gain Select Jumper This jumper is used to set the range of microphone and DTMF audio output from the 710 microphone. The 710 is shipped with JP1 installed (IN), and will accommodate requirements where the microphone audio is in the range of 40 mV or less. For transceivers that require a higher level microphone input, cut JP1 (OUT) as shown in Figure "A". Audio Output Level (RV2) This adjustment sets the microphone level for voice modulation only.
Manual Dialing Mode Manual dialing consists of pressing one or more of the 12 digits on the keypad to dial that number. This mode operates the same as a regular telephone keypad. When a key is depressed, the microphone will automatically key the transmitter and generate that DTMF digit. When the key is released, the DTMF generation will cease and the microphone will unkey the transmitter after a 2-second delay.
This mode allows the user to manually dial up to a 50 digit number before it is actually transmitted. Using this mode, a telephone number can be accumulated in memory, and then transmitted at a later time. It is accomplished by pressing the "0" key, followed by the telephone number desired. When you are ready to send the number, press the PTT switch briefly to initiate the transmission.
PROGRAMMING SPECIAL FUNCTIONS When programming numbers for autodialing or accumulated DTMF manual dialing, the following two-digit functions can be entered as part of the stored number.
and then the telephone number "555-1212". Send the ANI code at twice the normal dialing rate, and the telephone number at the normal autodialing rate.
PROGRAMMING SPECIAL FUNCTIONS -continued Summary of Manual Dialing Press any key to generate that DTMF digit. Press "*" or "#" to send ANI-UP or ANI-DOWN, if programmed. Summary of Autodialing To send a pre-programmed number sequence from a memory location, press the applicable key 1-8 to autodial. To store a number in a memory location: press 9 plus the memory location (1-8) plus number, and then press PTT switch to store. Press "*" or "#" to send ANI-UP or ANI-DOWN, if programmed.
