C-1000/S OPERATOR'S MANUAL
INTRODUCTION
This Operator's Manual contains detailed information to
assist you in the proper operation of the C-1000/S
Control Head.
Refer to the picture on the following page as you read
the operating instructions.
PURPOSE OF EQUIPMENT
The C-1000/S control unit is designed for use with Wulfsberg's
Flexcomm communication systems. Flexcomm provides FM
communications in low band VHF, high band VHF, UHF and
VHF AM. Flexcomm provides total flexibility for interagency
communications. The units provide channeling capability for all
the FM bands plus the air traffic control band.
The C-1000/S is a fully frequency-agile control unit. It provides
the ability to thumbwheel control all of the authorized Flexcomm
system channels. It also provides 30 programmable preset
channels. And the programming capability to change any of the
preset channel frequencies is built into the control unit. This
built-in operator programming capability can be disabled if the
user desires. Transceivers must be used only on your specifically
authorized frequencies.
NOTE: The C-1000/S Control Unit has shop accessible mode of
operation selector switches. The configuration of the switches
alters the operation of the control and the configuration must be
known to properly utilize the features of the C-1000/S.
Features and capabilities of the C-1000/S that may be internally
enabled/disabled are:
! THUMBWHEEL LIGHTING - normally the thumbwheels are
back-lit continuously for night use but may be internally
disabled.
! FREQUENCY AND TONE DISPLAY - normally the display
is off except when the present RCV/XMT switch is depressed
either to preset channel frequency and tone information or to
re-program the channel information. The display may be
configured internally for the display to be on continuously.
! GUARD CHANNEL PROGRAMMING - may be internally
disabled.
! PAGE A AND B CHANNEL PROGRAMMING – may be
internally disabled for page A or page B channels or both.
! MANUAL SIMPLEX CHANNEL - may be internally
restricted to receive only.
! CHANNEL MEMORY DISCRETE OUTPUTS – may be
shop programmed with each channel to provide control of
external accessory equipment. Should the operator
re-program a channel without access to the internal switches,
pre-programmed channel memory discrete information may
be lost. If the unit has been modified for narrow/wide band
operation, memory discrete number two will not be a userdefined discrete output.
DESIGN FEATURES
! The C-1000/S is designed for ease of operation, maintenance
and installation.
! Channel Memory retention maintained with no power
applied. Some restrictions may apply with S version
installations.
All Flexcomm control units are interchangeable within the
system wiring.
Guard channel transmit frequencies and tones.
Five Channel Memory Discrete Outputs (four when modified
for narrow band); shop programmable with each channel.
Direct/Repeat feature.
Integral front panel lighting.
FREQUENCY SELECTION
AND DISPLAY
Please note that the international aircraft standard is used in the
frequency selection and frequency presentation of the 0.5 kHz
frequencies. That is:
154.320 reads 154.320
154.3225 reads 154.322
464.325 reads 464.325
464.3275 reads 464.327
CONTROL OPERATION
The following describes the operation of each operator accessible
control knob, switch or indicator:
! PRESET CHANNEL SELECTORS: Allows selection of 30
channels of pre-programmed frequencies, tones and Channel
Memory Discretes.
! TEST/LOAD Switch: Disables the receiver squelch, also,
when activated simultaneously with the Preset switch, loads
preset frequencies, tones and five Channel Memory Discretes.
! PRESET - RCV/XMT Switch: Used in conjunction with the
LOAD/TEST Switch, selects either receive or transmit half of
channel memory. Activates seven segment frequency and
tone LED displays.
! MAIN RECEIVER Squelch Lamp: Indicates signal on Main
Receiver. Dims automatically.
! GUARD RECEIVER Squelch Lamp: Indicates signal on
Guard Receiver. Dims automatically.
! ON/OFF/VOLUME Control
! TONE - ON/OFF/MNL Switch: Allows manual selection of
transmitted tone by way of thumbwheel TONE selectors in
MNL position, allows Main and Guard tone squelches to
operate in the ON position, and allows Main and Guard
receiver tone squelches to be disabled in either the MNL or
OFF positions. In either the OFF or MNL positions the
receiver's squelches operate via their noise squelch circuitry.
T/R SELECT Switch -MAIN/BOTH/GUARD: In the MAIN
position - enables the Main Receiver only and transmits on
the main channel selected. In the BOTH position - enables
both the Main and Guard Receivers and transmits on either
the main or guard channel (dependent on the XMTR-MN/GD
switch); in the GUARD position - enables only the Guard
Receiver and transmits on the selected guard channel.
XMTR - MN/GD Switch: Selects either main channel or
guard channel during transmitter operation only if the
T/R-MAIN/BOTH/GUARD switch is in the BOTH position.
XMTR Lamp: Indicates transmitter operating, dims
automatically.
RPT/DIR Switch: Selects transmitter to operate on different
frequency than receiver (RPT) or same frequency as receiver
(DIR) during main channel operation. Selects one of two
guard channels during guard channel transmitter operation
and during guard transmit channel programming.
FREQUENCY and TONE Selectors: Internally lighted
thumbwheels used in manual selection and programming of
frequencies and tones. Lighting may be disabled by means of
an internal switch.
N/W SWITCH: Selects either Narrow or Wide Band
operation. When N is selected and the channel selector
switch is on M, an LED lights in the lower right corner of the
kHz display. The LED also lights when a preset memory
channel has been programmed for narrow band.
PRESET CHANNEL
PROGRAMMING INSTRUCTIONS
Turn the equipment On by rotating the MAIN ON/OFF volume
control clockwise. Aircraft or vehicle power must be available to
the unit by operating the appropriate switches and/or circuit
breakers.
To hear the audio, the appropriate audio select switches, if any,
must be in the proper position and the volume control set to the
appropriate level. The volume level can be tested setting the
background noise level generated when the TEST/LOAD button is
depressed.
NOTE: To optimize system performance, allow five minutes for
warm-up. Two and one-half minutes warmup is required to insure
the transmitter frequency is within the FCC requirements.
The programming procedures described in detail in the following
steps consist of
(1) Selecting the channel to be programmed.
(2) Setting up the channel frequency, tone and narrow/wide band
mode if the unit has the narrow band modification.
(3) Selecting receive or transmit with the PRESET switch.
(4) Pressing the TEST/LOAD Button while holding the PRESET
switch.
(5) Verification of proper load.
NOTE: Internal switches are provided to prevent control unit
programming or manual transmit frequency selection by operators
not having an FCC second class, or higher, commercial operator
license.
MAIN RCV/XMT FREQUENCY
1. Select the desired channel (page and number) to be
programmed on the channel selectors.
2. Set up the XMT frequency and CTCSS tone on the
thumbwheels. If no tone is desired, set the CTCSS selector to
the OFF position. To choose the proper tone code to be used,
refer to the Tone Selection Chart. If the unit has the narrow
band modification, set the N/B switch to the desired setting.
3. Set the T/R - MAIN/BOTH/GUARD to MAIN.
4. Operate the PRESET switch to the XMT position and hold.
5. Push and release the LOAD button. The XMT frequency is
now loaded for the selected channel.
6. Set up RCV frequency and CTCSS tone on the Thumbwheels.
7. Operate PRESET switch to the RCV position and hold.
8. Push and release LOAD button. The RCV frequency is now
loaded for the selected channel.
GUARD XMT FREQUENCY
1. Set the T/R MAIN/ BOTH/GUARD Switch to GUARD.
2. Any channel may be selected for the Guard frequency
programming operation.
3. Set XMTR RPT/DIR Switch to RPT.
4. Set up the Guard XMT repeater frequency and CTCSS tone
on the thumbwheels. If the unit has the narrow band
modification, set the N/B switch to the desired setting.
5. Operate PRESET Switch to XMT position and hold.
6. Push and release LOAD button. The Guard XMT Repeater
frequency is now loaded.
7. Change the XMTR RPT/DIR Switch to DIR and repeat steps
5 through 7 to load the Guard XMT direct or simplex

FREQUENCY REVIEW
To review main channel information, set the T/R
MAIN/BOTH/GUARD to the MAIN position or if the T/R
MAIN/BOTH/GUARD Switch is in the BOTH position, set the
XMTR MN/GD Switch to MN. The TONE Switch can be in
either the ON or OFF position, but should not be in the MNL
position. To review the XMT half of the memory, place the
PRESET Switch to the XMT position. To review the RCV half,
place the PRESET Switch to the RCV position. The frequency
and tone code stored in memory will be displayed.
To review guard channel information, set the T/R
MAIN/BOTH/GUARD Switch to the GUARD position or if the
T/R MAIN/BOTH/GUARD Switch is in the BOTH position, set
the XMTR MN/GD Switch to the GD position. Place the PRESET
Switch in the XMT position. To select between the repeater
(duplex/channel 1) or the direct (simplex/channel 2) guard transmit
frequency, use the XMTR RPT/DIR Switch.
MANUAL OPERATION
1. Rotate the Channel Selector Switch to the M channel.
2. Set the thumbwheels to the frequency and tone desired. The
selected frequency and tone is common to both transmit and
receive operation.
3. If modified for narrow band operation, set to either ‘N’ or
‘W’ depending on whether narrow or wide band operation is
desired.
NOTE: The operator of a C-1000/S control unit must hold a FCC
Second Class, or higher, Commercial Operator's License to utilize
the manual channel frequency selector mode of operation or the
operator channel programming feature for FM channels. When
VHF-AM frequencies are selected in the manual channel
frequency mode, the transmitter is automatically enabled regardless
of the operator restrictions for FM channels. Internal switches are
provided to prevent operation in the manual ("M") mode.
TONE SQUELCH
The CTCSS tone squelch may be preset to one of 32 possible tone
frequencies on each of the 30 programmable channels. The
transmit and receive tones may be different. Receive tone squelch
may be disabled for open receiver operation independent of
programmed tone via the "TONE OFF" switch. Transmitter tones
are not effected. Manual selection of the transmitted tone only
may be made via the "TONE MNL" switch and the thumbwheel
Tone Selector.
CHANNEL MEMORY DISCRETES
Five electronic switches (four if the unit has the narrow band
modification) for each channel are provided and are shop
programmable for each transmit and receive frequency. They can
be configured to activate or deactivate features or accessory units
as part of the Flexcomm System.
