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. Digicall Spectrum Student Transceiver (Figure 2)
Battery operated student transceivers are used to receive lesson source transmissions from the
console. These student units are capable of tuning to any one of the lesson sources on your console.
Each student unit can be remotely controlled from
the instructor’s console to allow monitoring,
recording and private intercommunications
between individual students and the instructor.
Remote control of the student unit for monitor and
intercom functions is accomplished by the
transmission, reception and decoding of a digital
code. Student unit numbers are entered through the
touch switch control panel keyboard, stored,
converted into the digital code and transmitted
along with the lesson to the student unit.
Figure 2
When a student unit receives its own digital code, the student’s voice along with the program is
transmitted back to the instructor’s console. This permits the instructor to monitor or record the
student’s progress.
1.2.2. Student Headset (Figure 3)

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.

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.
Follow these three simple steps:
•
Turn on the console power switch, located in the upper right corner of the panel.
•
Hand out the Student headsets and transceivers to the students and follow the operating
instructions in section 2.2 of this manual.
•
Turn on the lesson source desired and follow the operating instructions for that lesson source
explained in 2.1.3.1.
Once the students have put on their headsets and adjusted them, explain the purpose of your language
laboratory to them. To do this, press the “ALL CALL” button on the black control panel. All of the
students in the classroom will now hear your voice. This will give your class the opportunity to
familiarize themselves with the sound of your voice as it comes from your microphone.
Figure 5
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. T2400 Instructor Headset and Volume Control
Plug in the “INSTRUCTOR HEADSET” all the way! Fleetwood
suggests that you adjust the “INSTRUCTOR VOLUME” to
maximum by holding down the “VOLUME UP ARROW
BUTTON” for several seconds and adjust it later only after a lesson
source has been selected and the volume of that lesson source has been set. See the next section to
select the lesson source. A Guest Instructor jack allows a second headset to be plugged in to
participate with the Instructor.
2.1.1.3. Lesson Select
These buttons allow the Instructor to select the lesson source to monitor. The numbers 1 through 6 on
the “LESSON SELECT” buttons correspond to the lesson source (cassette player, CD player, VCR).
To monitor a lesson source you must first select the lesson source via the “LESSON SELECT”
buttons and then start the lesson source. Refer to the operation section of this manual for that source.
The lesson source selected will be restored upon power-up.
IMPORTANT: Always adjust the volume of the lesson source so that the “LESSON LEVEL”
indicator only fluctuates into the yellow area, but rarely into the upper red range.
See section 2.2 of this manual for operation of the student transceivers.
2.1.1.4. Function
2.1.1.4.1. All Call
Place any active lesson sources in pause or stop mode. When in this mode, the students do not hear
any lesson material. To talk to all students simultaneously, press the “ALL CALL” button. Be sure to
cancel “ALL CALL” by pressing the button again or by pressing a “LESSON SELECT” button when
finished.
IMPORTANT: You cannot monitor or intercom with any students if the “ALL CALL” or
“MIC WITH LESSON” modes are active.
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. Students will notice that during this mode, the lesson automatically drops in audio level,
making the instructor’s voice easily understood. If the Instructor wants to have a clear channel to
speak with the students without any lesson, pause the lesson source.
2.1.1.4.3. Student Monitor
To monitor a student’s response and lesson, enter the two-digit number of the student’s headset on
the keyboard in the same manner you would with a calculator. These numbers will appear on the
digital readout. When the second digit is depressed, the student’s lesson and responses will be heard.
The Instructor’s Lesson audio will no longer be heard as long as the two digits are non-zero.
NOTE: If the student headset that is selected is not turned on or if a nonexistent student
number is selected, the console will still try to monitor the student but no audio will be
heard by the instructor. A small period to the right of the headset number will light if
that headset is transmitting and is being received properly.
2.1.1.4.4. Student Record
To record a student’s response and lesson, enter the two-digit number of the student’s headset on the
keyboard in the same manner you would with a calculator. These numbers will appear on the digital
readout. When the second digit is depressed, the student’s lesson and responses will be heard. The
Instructor’s Lesson audio will no longer be heard as long as the two digits are non-zero.
Then select a console recorder that is not being used as a lesson source and place the recorder in the
record mode. You will now record the student whose number is shown on the digital display, and the
lesson. To play back this student’s recording to the individual student, follow the instructions under
“STUDENT REVIEW”.
2.1.1.4.5. Student Review
To play back the recording of a student, press the “STUDENT REVIEW” button. Press the
“LESSON SELECT” button for the lesson channel corresponding to the tape deck that you recorded
the student on in section 2.1.1.4.4 above. Rewind the recording back to the beginning of the tape and
then enter the student headset number that was recorded (if that student number is no longer on the
display) and push the “INTERCOM W/ LESSON” button as described below. Start the tape to play
the recording to that selected student through the intercom function.
2.1.1.4.6. Intercom (ON / W Lesson)
This button permits the instructor to determine whether the lesson is present during intercom with the
student or whether the channel will be clear. The “ON / W LESSON” mode can be helpful when the
instructor wants to talk to the student and point out particular points of interest in the lesson as it is
playing.
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.
NOTE: The lesson provided during ON / W 7Intercom is determined by the setting of the
Instructor “LESSON SELECT” button.
2.1.1.4.7. Intercom (ON / W Mute)
This button is functionally identical to “ON / W LESSON” except that no lesson will be heard during
the instructor-student conversation.
To intercom with a student, enter the student headset number on the display and then depress the
“ON / W MUTE” button. The student’s lesson will no longer be heard and you will be able to carry
on a private two-way conversation. When active, the “ON / W MUTE” 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.
2.1.1.4.8. Remote Headset
The Remote Headset function enables a spare student headset to be used to provide an audio feed to
one of the lesson channels. This can allow a teacher to freely move around the room while being able
to act as a lesson source or provide additional comments on one of the channels. When supervised
properly by a teacher, it can also allow any student to perform a recite function for the benefit of the
rest of the class.
To perform the Remote Headset function, the teacher should press the appropriate “LESSON
SELECT” button to determine the lesson the remote headset audio will be fed to, enter the number of
the headset to be used as the remote headset, and press the “REMOTE HEADSET” button. The
selected channel may be either a quiet channel or a channel with an active lesson source. Any
students who have their lesson set to this channel should be able to hear the remote headset and
lesson if active.
There are two ways of setting the lesson channel on the remote headset. The preferred and safest way
is to set the remote headset to an unused lesson channel while making sure the volume control is set
sufficiently high to not allow the headset to turn off. This has a disadvantage of not allowing the
teacher or student to hear an active lesson if there is one. Fortunately this function is used most
frequently by a teacher to function as a roving lesson source without an active lesson so the inability
to hear the lesson is not a problem.
The second method should only be used if the remote headset is being used along with an active
lesson source to add comments or recitation with the lesson. In this case the remote headset must be
set to the same channel as the console. The volume control setting on the remote headset becomes
critical because the headset voice audio is being fed back into the headset on the lesson and if the
volume is set too high the system may go into feedback resulting in a howl on the lesson channel.
This needs to be controlled closely by the teacher. The volume control should be set high enough to
sufficiently hear the lesson and no higher. If feedback (loud squeal) occurs, the remote headset level
is set too high and should be reduced. If it is reduced too far however, the headset may turn off. A
volume setting where the lesson is slightly on the low side should provide satisfactory performance.
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. This is useful in order to allow the instructor to add the student’s name or other
comments for future reference. The lesson recorder must be in record mode in order to retain these
comments for future playback.
2.1.1.5. Lesson Level Indicator
The Multi-segment Bar Indicator is used for setting the lesson source to the proper audio level. This
is done by adjusting the lesson level so that the “LESSON LEVEL” Indicator on the console
occasionally fluctuates into the yellow area, but rarely into the upper red range. This should allow
the students to set their volume levels to the middle of their volume range. This will prevent the
headsets from shutting off automatically due to low RF levels being received by the headsets.
NOTE: The console and the student headset must be turned on to perform this function. If the
headset volume level is too low, the headset will turn off.
2.1.1.6. AUX Input Jacks
To use an external lesson source (AM/FM Radio, CD Player, Cassette Player, etc..), plug a patch cord
from the speaker or earphone output jack of your portable source to the desired “AUX INPUT
JACK”. Using an external lesson automatically disconnects the built-in lesson on that channel. To
listen to this lesson on the instructor’s headset, press the “LESSON SELECT” button for the same
channel number.
NOTE: The jacks that are covered with a plastic cap, do not have a channel transmitter and
consequently are not active. The number of active jacks is determined by how many
built-in lessons and separate auxiliary input channels are purchased. This console may
be equipped with circuitry that prevents the use of a lesson when a transmitter is not
present. This will be indicated by the inability to select that Lesson with the “LESSON
SELECT” buttons.
IMPORTANT: Always adjust the volume on the external lesson for a “LESSON LEVEL” that
occasionally fluctuates into the yellow, but rarely into the upper red range.
2.1.1.7. Student Selection
To select an individual student, enter the two-digit number of the student’s unit on the keyboard in
the same manner you would with a calculator. These numbers will appear on the digital readout.
When the second digit is depressed, the student’s lesson and responses will be heard.
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. If you prefer the console to start with a student other than #10, enter another student’s
unit number on the “STUDENT SELECTION” keyboard and press the “RUN/STOP” button of the
“AUTOMATIC SEQUENCER”. The microprocessor will start monitoring that student number and
sequence upward rather than starting with #10. This feature will allow you to start your monitoring or
recording process with any student number. The student numbers will be monitored in sequence.
However, if any student unit number is missing, the microprocessor will quickly move onto the next
student number. The microprocessor scans all 63 possible student numbers. If you have less than 63
student units in your lab and wish to reduce monitoring time for student headsets that are not active,
see the instructions on “SET RANGE” in section 2.1.1.8.4.
2.1.1.8.1. Run/Stop
If at any time during the automatic mode you would like to monitor a student longer than the 30
seconds, push the “RUN/STOP” button and the microprocessor will pause on that student until you
push the “RUN/STOP” button again. When “RUN” is inactive (STOP), the red light will go out.
This function is just as if you had entered the student’s number without using the “AUTOMATIC
SEQUENCER”. Press “RUN” to continue automatically.
2.1.1.8.2. Random
The “RANDOM” button allows sequencing through headset numbers in a random order rather than
sequentially. Pressing the “RANDOM” button again can turn this off. This mode is useful during the
“AUTOMATIC SEQUENCER” “RUN/STOP” mode and also when manually sequencing using the
“NEXT” and “PREV” keys as described below.
2.1.1.8.3. Next/Prev
If you desire to shorten the monitoring time or skip over a student number, push the “NEXT” or
“PREV” button quickly and advance to the next number. If you hold either button down, it will
quickly advance through the student numbers until it is released.
The “PREV” button can be used to recall the previously monitored student during the normal
“RUN/STOP” sequence or when using “RANDOM”. Pressing this button repeatedly when in the
“RANDOM” mode allows an instructor to continually focus on a particular student address while
also reviewing other students in an alternating fashion.
If you feel that monitoring a student for the period of 30 seconds is either too short or too long and
you would like the system to automatically monitor for a different length of time, see the operating
instructions for “SET PERIOD” in section 2.1.1.8.5.
If at any time you are using the “AUTOMATIC SEQUENCER” to monitor students and you
“INTERCOM” with that student, the “AUTOMATIC SEQUENCER” will hold on that student
number until you again press the appropriate intercom button, which will cancel intercom and
continue sequencing.
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. Press the “SET RANGE” button a second time and the number 99 (or the last “HI” value) will
show in the display. Enter the highest number headset in your class.
3. After entering this number, press the “SET RANGE” key again. At which time the letters
“LO” will appear in the display.
4. Press of the “SET RANGE” button again. The number “1” (or the last “LO” value) will
appear in the display. If the lowest numbered student unit in your class is greater than “10”
enter that number in the display.
5. Pressing of the “SET RANGE” button again returns the console to the monitor mode. The
“AUTOMATIC SEQUENCER” will now be reset to the highest and lowest numbered unit in
the class.
If you wish to review the student unit numbers stored in the “HI” and “LO” memory, press
the “SET RANGE” key again after the “HI” or “LO” appears. The high and low student unit
numbers will appear on the display.
NOTE: Each time your console is turned off, the “AUTOMATIC SEQUENCER” will
remember the range settings for the next session.
2.1.1.8.5. Set Period
To change the length of time that each student is automatically monitored when using the
“AUTOMATIC SEQUENCER”, press the “SET PERIOD” button and notice the “SP” on the
display. Pressing “SET PERIOD” again will show the present timer setting, in seconds, on the
display. If you wish to change the setting, enter a new number. The timer may be set from 1 second to
99 seconds. For numbers 01 to 09, the leading “0” must be entered. Press the “SET PERIOD” or
“CLR” to return the console to the normal monitoring mode.
NOTE: Each time your console is turned off, the “AUTOMATIC SEQUENCER” will
remember the period range setting for the next session.
2.1.1.9. Save/Recall
The Digicall Spectrum system allows an instructor to save individual preferences for future recall.
The instructor can save Period and Range settings, volume settings, and the last lesson used in 10
different memory locations. This allows customized settings to be quickly restored for up to 10
different instructors or classes.
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. Volume
To adjust the Instructor/Guest headset volume, press the triangular buttons. The triangle pointing up
is to increase the volume and the triangle pointing down, is to decrease the volume. The buttons can
either be held down or repeatedly pressed to increase or decrease the volume.
This volume controls both the Instructor and Guest headsets simultaneously. The lesson level
indicator will display the current volume setting each time the volume buttons are pressed.
NOTE: When the console is turned on, the “Volume” to the Instructor/Guest headset will
return to its last volume setting.

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. For Cue, simple press the “FF/CUE” key (while the tape is
playing) and the tape will skip forward. When the “REW/REV” or “FF/CUE” key is released, the
machine will automatically go back into play.
2.1.2.1.5. Rewind
Push the “STOP” key and then the “REW/REV” key to rewind any part of the tape.
2.1.2.1.6. Recording
To record, insert a cassette, push the “REC” key. Proper recording levels will be achieved when the
level of the lesson source being copied that occasionally fluctuates into the yellow, but rarely into the
upper red range on the audio bar indicator on the control panel.
To record another lesson source, select the lesson to be copied by the “LESSON SELECT” button.
Whatever is heard in the instructor’s headset will be recorded on the recording deck(s).
NOTE: A recording cannot be made with the record tab removed. The cassette needs this tab
to depress the record button inside the cassette door area. (Record tab is located on top
rear edge of the cassette)
2.1.2.1.7. Fast Forward (FF)
To fast-forward the cassette tape, depress the “FF/CUE”. This advances the tape forward. To stop the
tape, press the “STOP/EJECT” key once.

4. Plug the VCR power cord into the AC outlet.
5. Locate the coaxial connector on the outside (right side) of the console.
6. There is a coaxial cable supplied with the VCR. Connect the cable to the coaxial terminal on
the side of the console and to the VHF input of your monitor.
7.
Set the VCR RF channel switch (refer to the Manufacturer’s operating instructions for the
location of this switch) to 3 or 4, whichever channel is not used in your area, then make sure
your TV is set to that channel.
2.1.4.2.1. Volume
The volume knob for the VCR is located below the control panel. When adjusting the volume, set the
Instructor’s “LESSON SELECT” button to the same number that is on the lesson source.
Turn the TV volume control down to it’s lowest level if you do not wish the audio to be heard
through the TV built in speaker.
12
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.

Application Guidelines For Fleetwood Digicall
Spectrum Wireless Learning Laboratory
The following guidelines must be followed to insure proper installation and operation of Fleetwood’s
Digicall Spectrum Wireless Learning Laboratory.
1. Space two Digicall Lab systems operating with the same channels a minimum of 100 feet
from one another.
2. If there is more than one lab per school, there should be a space of one classroom in between
them. By keeping this distance, you can minimize the possibility of interference between
lesson channels from one room to another.
3. Adjust the “LESSON LEVEL” so that the multi-segment bar indicator occasionally fluctuates
into the yellow, but rarely into the upper red range. This should allow the students to set their
volume levels to the middle of their headset volume range. This will prevent the Student
Transceivers from shutting off automatically due to low RF levels being received by the
headsets.

General Information About Wireless Systems
5.1. How to Avoid Interference Between Lessons When 2 Labs are
Required
WILL PLEASE HELP WITH THIS
If there is more that one lab per school, and you would like to have 6 lesson channels in each console
then these labs must be placed at least the distance of a hallway in between them or if they are on the
same side of the hallway, there should be a space of one classroom in between them. By keeping this
distance, you will minimize the possibility of interference between lesson channels from one room to
another.
Another way to avoid interference between lesson channels, if the two rooms must be side by side,
back to back or above and/or below each other, is to limit the consoles to three lesson sources (three
channels each) instead of 6. Put three channels in each console, one console having channels 1, 2, and
3 and the others having channels 4, 5, and 6. Use this method for two Digicall or any other wireless
systems.

Appendix A - Diagnostic Modes
The following information is provided in order to prevent accidental entry into the special diagnostic
modes that have been programmed into your Digicall Console. Your console may not include all of
these functions or may include additional modes that are explicitly reserved for factory use. Each of
these modes will generally only be used by factory qualified representatives for diagnostic
evaluation. On occasion, you may be asked to exercise one of these modes under the direction of a
field service technician. Your Digicall console has been shipped from the factory with the correct
configuration and should not require use of these functions under normal use.
1) RESTORE FACTORY DEFAULTS - This mode restores factory default settings for Range,
Period, Lesson, and Volume. This mode is activated by holding down the "CLEAR" button while
turning on power to the console. The range settings will be restored to HI=99, LO=1. The Period
setting will be restored to 30. The Lesson will be reset to lesson 1. Volume will be set to midrange.
2) KEY CODE DISPLAY - This mode is activated by holding down the "ALL CALL" button when
turning on power to the console. This is a special diagnostic mode that allows testing of the codes
used to identify individual buttons on the console. This mode will be active until the console is
powered off and back on again.
3) SIMULATED LESSON TONES - This mode is activated by holding down the "MIC W/
LESSON" button while turning on power to the console. This is a special diagnostic mode that
allows generation of fixed tones that can be heard on each of the 6 lesson channels. These tones
may be used by field service personnel to test various modes of operation. This mode will be
active until the console is powered off and back on again.
4) REVISION DISPLAY/LIGHT TEST - This mode allows the user to view the revision level of the
microprocessor firmware. This mode is entered by holding down one of the "VOLUME" buttons
while turning on power to the console. The system test will be slowed, such that the individual
indicators can be viewed, if the button is held down following the display of the revision.
