1. General Description 1.1. Digicall Spectrum Console (Figure 1) The Digicall system is designed to work within the normal classroom size of approximately 30’ x 30’. (See Figure 4) This equipment is a low power communication device using amplitude modulation. All transmitting circuits are factory certified to meet Part 15 radiation requirements of the FCC rules and regulations (see section 7). Factory seals, when broken, void this certification. Figure 1 1.2. Student Transceivers 1.2.1.
1.2.3. T2400C Teachers Headset (Figure 4) This Headset is used by the instructor to monitor the lessons at the console and the students, and is plugged in at the console. Figure 4 2. Principles Of Operation 2.1. ECM984 Digicall Spectrum Console Your Fleetwood console is designed for ease of operation, using a soft touch membrane control center. Your first day’s experience in operating your new language lab should be interesting and exciting.

2.1.1. Digicall Spectrum Control Panel (Figure 5) NOTE: Please refer to Figure 5 when reading the next section. 2.1.1.1. Power Switch Turn on the power with the white rocker switch at the upper right corner of the control panel. A lesson indicator will light (red) and two zeros (“00”) will appear on the digital display. 2.1.1.2.
2.1.1.4.2. Mic w/Lesson (Microphone with Lesson) This function is used by the instructor to talk to all students listening to the same lesson channel as selected with the “LESSON SELECT” buttons. For example, to talk to students listening to lesson channel #1, press the “LESSON 1” button and the “MIC W/ LESSON” button. Be sure to cancel “MIC W/ LESSON” by pressing the button again when you no longer wish to speak with the students.
To intercom with a student, enter the student headset number on the display and then depress the “ON / W LESSON” button. The student’s lesson will continue to be heard and you will be able to carry on a private two-way conversation. When active, the “ON / W LESSON” light (red) will come on and the display lights will blink to indicate the intercom function. To return to monitoring the student, depress the button again.
IMPORTANT: If feedback (loud squeal) occurs in the remote headset, select a different channel OR reduce the volume on the remote (student) headset. Be aware, however, that if the headset volume is turned down too far, you may cause the headset to turn off. 2.1.1.4.9. Record Comment This button may be depressed and held down at any time to allow instructor comments to be recorded on a lesson recorder.
2.1.1.8. Automatic Sequencer (Monitoring a Student Automatically) To monitor students automatically, press the “AUTOMATIC SEQUENCER” “RUN/STOP” button. Automatically the #10 student number will appear on the digital display and you will immediately hear that student’s lesson and response for a period of 30 seconds. (See section 2.1.1.8.5) The (red) “RUN” indicator light will come on indicating the automatic monitoring or recording function is taking place.
2.1.1.8.4. Set Range This Digicall Spectrum system accommodates classes up to 63 students. The “AUTOMATIC SEQUENCER” is factory set to monitor student transceiver numbers “1” through “99” (99 headsets). Most classes have fewer than 99 students. In order to save searching time in the automatic mode, the range of the “AUTOMATIC SEQUENCER” should be set for your class size. To do this, complete the following steps: 1. Press the “SET RANGE” button. The letters “HI” will appear in the display. 2.
To save a specific settings group, hold down one of the 0-9 digit buttons (used to enter student address) until the letters “SA” are displayed (several seconds beyond “rE”). Release the button at this time to “SAve” these settings. To recall a specific settings group, hold down one of the 0-9 digit buttons (used to enter student address) until the letters “rE” are displayed. Release the button at this time to “rEcall” these settings. 2.1.1.10.
IMPORTANT: Always adjust the volume on the lesson for a “LESSON LEVEL” that occasionally fluctuates into the yellow, but rarely into the upper red range. Too much meter deflection into the red will cause the students to turn their volume down in their headsets, which could cause the headsets to turn off. 2.1.2.1.4. Review And Cue While listening to a tape, you can review a portion of the lesson tape by holding down the “REW/REV” key and then releasing it.
2.1.3.1. General Operating Instructions Refer to the Manufacturer’s operating instructions supplied with the Digicall Console. 2.1.3.1.1. Volume To adjust the volume, set the Instructor’s “LESSON SELECT” button to the same number that is on the lesson source. IMPORTANT: Always adjust the volume on the lesson for a “LESSON LEVEL” that occasionally fluctuates into the yellow, but rarely into the upper red range.
