2CITATION 20SYNTHESIZED INTELLIGENCE KITDESCRIPTIONThe Tactical Technologies Inc. CITATION 20 Synthesized Briefcase Intelligence Kit is amultipurpose system designed for portable receiving and/or recording of covert intelligencegathering operations.The receiver is a highly sensitive narrow band synthesized VHF-FM receiver with a 100 channelmemory that operates in the 150-174 MHz range and is designed to meet the NTIA-102narrowband (12.5 kHz channel spacing) standards. The receiver can also be set to receivetransmissions from devices designed prior to the NTIA-102 standard (25 kHz channel spacing).An informative LCD display and multiple LED bar graphs highlight the Citation 20's controlpanel. The unit is easy to program either in the Tech Office or "on the road". The unit's softwarefeatures a "FIELD SECURE" mode that eliminates the numeric frequency information from theLCD display and leaves only the channel number and the assigned alpha/numeric name. In thismode, the programmed frequency list is protected from additions or subtractions.The recording system comes with a high quality Marantz PMD 201 cassette recorder, and themonitoring system is enhanced with Tactical Technologies Inc.'s own dual band Digital AudioControls. Bass and/or Treble frequencies of the received audio can be monitored during initialreception, or during playback of a recording. These tonal adaptations will NOT be recorded viathe on-board Marantz, thus retaining the integrity of the original recording. Also included asstandard equipment is an Adaptive Digital Audio Filter (DSP switch), which can eliminateunwanted background noise from the received audio, or from a pro-recorded session. This ADAFaudio also can NOT be recorded via the on-board recorder.The panel includes many illuminated displays and switches - all of which can be turned off so thatthe panel remains dark for night time operations when this is a necessity.As an option, the CITATION 8 can be equipped with descrambling. This will permit decodedreceiving/recording of a scrambled transmission from a compatibly scrambled Tactical Technolo-gies Inc. transmitter or repeater.GENERAL OPERATIONSINITIAL SETUPPOWER1.) Select one of the three possible power sources you will be using during operations.a.) Internal Rechargeable Battery Pack.No additional setup is required. Check to make sure battery if fully charged. Seesection entitled "CHARGING AND CARING FOR THE INTERNAL BATTERY"b.) External 12 VDC power source.
3Connect the single pin female connector found on the 12VDC cigarette lighter cable tothe male connector found on the left outside panel of the Citation 20 case. Push thecable end connector into the panel mounted connector on the case. Lock the connectorstogether by rotating the sleeve on the cable end clockwise to thread it onto the panelmounted connector. Hand tighten only.c.) 110 VAC power source.Connect the 3 pin female connector found on the 110 VAC cable to the male connectorfound on the left outside panel of the Citation 20 case. Locate the correct alignmentconfiguration, and push the cable end connector into the panel mounted connector onthe case.2.) Turn power on by pushing the POWER switch. The LED indicator on the switch shouldilluminate and the LCD display should come on, indicating that the unit is operational under theselected power source.PROGRAMMING THE CITATION 20The Citation 20 can store frequency and name information for up to 100 channels in itsnonvolatile, internal memory. Use the KEYPAD for data entry and retrieval.LAMPThe LAMP key toggles the LCD displays illumination on and off.It is advisable to use the Lamp sparingly during internal battery operations in an effort to conservebattery life.PROGRAMMING A FREQUENCY ...1.) SELECT A CHANNEL TO BE PROGRAMMEDA.) Press the CHNL key. A blinking cursor will appear at the first digit of the NUMERICCHANNEL NUMBER on the display. Enter a two digit channel number from 00 to 99.Or........B.) Press the UP ARROW or the DOWN ARROW keys to scroll through the channelnumbers. Stop at the desired channel.The Citation 20 retains "last active channel frequency information" in its memory at all times.When changing channels from an active, programmed channel to a blank, non-activechannel, the synthesizer will keep the receiver tuned to the last active frequency until a newfrequency is either programmed in, or a channel is selected which has been preprogrammed.So even though the display may be on a blank channel, the receiver may still tuned to anactive channel. This operation is normal.2.) ENTER A FREQUENCY FOR THE DISPLAYED CHANNELPress the FREQ key , then enter the frequency.Once the FREQ key is pressed, the display shows a blinking cursor on the FREQUENCYportion of the display.The frequency portion of the display looks like this:
4 Your data entry begins with the tens column. The hundred's column and the decimal pointare permanently displayed.The standard Citation 20 will accept any frequency from 150.0000 MHz through 174.0000MHz, in 2.5 kilohertz steps. Data entry into the thousandths column must be either a 0, 2, 5,or a 7. The Citation will automatically fill in the last column. A "0" in the thousandthscolumn yields a "0" in the final column, "2" yields a "5", a "5" yields a "0", and a "7" yields a"5". Any other entry in the thousandths column is an invalid entry, and the Citation willreturn a blinking cursor, requesting valid data. Please see the following example:Your initial entry is 154.65 .......154.65 -> you enter "0" -> display shows 154.6500 MHz Valid154.65 -> you enter "1" -> display shows 154.65?? MHz Invalid154.65 -> you enter "2" -> display shows 154.6525 MHz Valid154.65 -> you enter "3" -> display shows 154.65?? MHz Invalid154.65 -> you enter "4" -> display shows 154.65?? MHz Invalid154.65 -> you enter "5" -> display shows 154.6550 MHz Valid154.65 -> you enter "6" -> display shows 154.65?? MHz Invalid154.65 -> you enter "7" -> display shows 154.6575 MHz Valid154.65 -> you enter "8" -> display shows 154.65?? MHz Invalid154.65 -> you enter "9" -> display shows 154.65?? MHz InvalidIf you attempt to enter an invalid frequency, the Citation will either:1.) Return the blinking cursor to where your initial error happened - requesting you to re-enter your data. Or .....2.) Make you complete the programming, leaving at least one "?" as part of the displayedfrequency. If this happens, press the FREQ key again, and re-entry your data.To change the frequency of a channel that has previously been programmed:Simply press the FREQ key, and over write the old channel with the new data.If you make an error in your data entry.......1.) Complete the frequency, then over write the wrong entry with the correct one. Or....2.) Press the POWER button, turning the unit off, BEFORE you have completed the newfrequency data entry. Then turn it on again. This will return the channel to its originalfrequency.Once a channel is programmed, it can not be individually cleared from memory.NAMING THE CHANNEL.....Enter up to 12 Alpha/Numeric characters to name the channel.
51.) Press the NAME keyThe cursor will blink on the first of the twelve alpha/numeric segments on the display. Thisdisplay area is called the ALPHA/NUMERIC CHANNEL NAME .2.) Enter the first character of the channel name using the DATA ENTRY PADUpper and lower-class letters A-Z, the numbers 0-9, and a BLANK space are available for thechannel name. Use the UP ARROW and/or DOWN ARROW keys on the keypad to scrollyou through the selections.3.) Press the NAME key again to set the selected character and move the cursor to the next letter.Enter the next character using the procedures described above.4.) Continue to enter characters, pressing the NAME key each time to set the character and moveto the next letter. When finished, press the NAME key repeatedly until the cursor disappears fromthe display.If you make a mistake in data entry .....Press the NAME key repeatedly until the cursor scrolls back to the erroneous character. Over writethe wrong data with the correct character. When finished, press the NAME key repeatedly untilthe cursor disappears from the display.FIELD SECURE MODE vs. FULL PROGRAMMING MODEThe initial operating condition of a new Citation 20 is called the FULL PROGRAMMING MODE.In this state, all available functions are accessible and operational to the user, including synthesizerprogramming and memory clearing. The Citation 20 is equipped with a second operatingcondition called the FIELD SECURE MODE. Field Secure Mode eliminates some functions andadds protection to the memory. Field Secure adds the following features to the unit:1.) WRITE PROTECTEDa.) Frequencies that are preprogramming into the unit can not be changed.b.) New frequencies can not be added.c.) Names that are preprogrammed can not be changed.d.) The overall memory of the Citation 20 can not be cleared.2,) HIDES FREQUENCYa.) LCD only displays NUMERIC CHANNEL NUMBER and ALPHA/NUMERICCHANNEL NAME. The Frequency is eliminated - thus preventing field agents from seeingactual operating frequency numbers.b.) Disables the NAME and FREQ buttons on the keypad.TO PLACE THE UNIT IN FIELD SECURE MODE:a.) With the unit in Full Programming Mode, turn the Citation 20 OFF. Use the small FSMtool provided and insert it into the female RCA LINE jack found on the panel. Inside thisjack is a switch. Using the tool, lightly press on the switch, then extract the tool. When theswitch is engaged, the Citation 20 will be in FIELD SECURE MODE. (When the switch isdis-engaged, the unit is in FULL PROGRAMMING MODE.)b.) Turn the POWER switch ON.c.) Observe display - see that the numeric frequency information has been deleted.d.) The Citation will remain in Field Secure Mode, regardless of power conditions, untilswitched to revert back to Full Programming Mode.
6TO RETURN THE UNIT TO FULL PROGRAMMING MODE:a.) With the unit in Field Secure Mode, turn the Citation 20 OFF. Use the small FSM toolprovided and insert it into the female RCA LINE jack found on the panel. Inside this jack isa switch. Using the tool, lightly press on the switch, then extract the tool. When the switchis dis-engaged, the Citation 20 will be in FULL PROGRAMMING MODE.b.) Turn the POWER switch ON.c.) Observe display - see that the numeric frequency information has returned.d.) The Citation will remain in Field Secure Mode, regardless of power conditions, untilswitched to revert back to FIELD SECURE MODE.CLEARING THE MEMORYShould it become necessary to clear the entire memory of the Citation 20:1.) Turn the unit ON.2.) Make sure the unit is in the FULL PROGRAMMING MODE.3.) Select CHANNEL 00.Press and hold the UP ARROW or DOWN ARROW key until CHANNEL 00 is onthe display.or press the CHNL button and then type in 00 from the keypad4.) Press and release the FREQ key.5.) Press and release the ENTER key.6.) Using the FSM tool, insert the tool into the LINE jack. Engage the FSM switch insidethe jack AND HOLD THE SWITCH IN THE ENGAGED POSITION FOR AT LEAST 3SECONDS. Then release the switch.7.) Depress this switch with the tool once again, to dis-engage the switch and return the unitto FULL PROGRAMMING MODE.8.) Observe the display, you will see the frequencies being erased, from 00 through 99.9.) Turn the Citation OFF via the POWER switch.10.) Turn the Citation ON via the POWER switch.All the channels will now be erased.NOTE: MAKE SURE YOU HAVE A WRITTEN COPY OF ALL YOUR FREQUENCYINFORMATION BEFORE CLEARING THE MEMORY OF THE CITATION 20. THISPROCESS IS NON-REVERSIBLE.NOTE: YOU CAN ERASE THE MEMORY FROM ANY CHANNEL NUMBER THROUGHNUMBER 99 BY SELECTING ITS CHANNEL NUMBER INSTEAD OF 00 (step 3 above).As an example - you have channel numbers 00-12 programmed with frequencies youwish to keep. Channel 13, 20, 39, and 80 have information stored in them that you don NOTneed. Simply select channel '13' when you reach step 3 in the directions. The memory willbe cleared from channel 13 through 99, leaving the information in 00 through 12 intact.You can NOT individually clear a specific channel, or an interior range of frequencies.The range must go from a channel (with 00 being the lowest) through to 99.ADD THE ANTENNASelect either the Internal Antenna or the use of an External Antenna
7FOR AN EXTERNAL MAGNETIC MOUNT ANTENNAa.) Push the female BNC connector attached to the cable end of the Mag MountAntenna onto the male BNC connector found on the left exterior of the Citationbriefcase. Be sure to align the tabs on the male connector with the slots on the femaleconnector for proper operation. Secure the two together by pressing the femaleconnector firmly onto the male connector until it stops, then twist the female connectorclockwise until you hear a click. The two connectors are then locked together.b.) Locate the antenna whip and make sure the silver screw connector is attached to thebottom of the whip. If it is not, first slide the whip through the hole in the silver screwconnector, making sure the threaded portion of the connector is facing away from theantenna after insertion. Then screw the antenna assembly onto the magnetic base byturning the screw connector clockwise onto the base. Hand tighten only. DO NOTOVER TIGHTEN THE ANTENNA TO THE BASE.c.) Select the External Antenna Operation via the ANT selector switch found on theCitation's Control Panel . Observe the condition of the LED indicator above the ANTswitch. If the LED is RED, external antenna operation is selected. If the LED isYELLOW, push the switch once to turn the LED to RED and set the unit in ExternalAntenna mode.FOR INTERNAL ANTENNA:a.) Select the Internal Antenna Operation via the ANT selector switch found on theCitation's Control Panel . Observe the condition of the LED indicator above the ANTswitch. If the LED is YELLOW, internal antenna operation is selected. If the LED isRED, push the switch once to turn the LED to YELLOW and set the unit in InternalAntenna mode.Your Citation 20 is now ready to either receive a transmission, record a transmissionreceived via the inboard receiver, or playback a prerecorded tape.RECEIVING TRANSMISSIONS1.) Select the Channel to be monitored - corresponding to the appropriate frequency forcompatibility with your transmitter - via the KEYPAD.2.) Select the BANDWIDTH of the transmission you will be listening toSelect the bandwidth via the B/W switch found on the control panel, just to the right of thekeypad. This switch toggles the receiver between the new 12.5 kHz channel spacing NTIA-102extra narrow narrowband standard, and the older 25 kHz channel spacing wider narrowbandstandard. Each time you press the switch, the LED indicator cycles color from RED to YELLOW.When the LED is RED, the unit is in the NEW 12.5 kHz mode. When the LED is YELLOW, theunit is in the OLD 25 kHz mode.3.) Set the RECD/PLAY switch to the RECD (record) position.This switch toggles the Citation's audio-play system between the reception from the receiver andthe playback function of the on-board recorder. Each time you press the switch, the LEDindicator cycles color from RED to YELLOW. When the LED is RED, the unit is in theRECORDER PLAYBACK mode. When the LED is YELLOW, the unit is in the MONITORRECEIVER AND RECORD RECEPTION mode.
84.) Select the operation for the DSP switch (DIGITAL SIGNAL PROCESSOR FILTER - or theAdaptive Digital Audio Filter)This switch toggles the Citation's Digital Signal Processor Filter operation between three settings:OFF, 14dB of digital filtering (max. filtering), and 8dB of digital filtering (minimal filtering).Each time you press the switch, the LED indicator cycles color from OFF to RED to YELLOW.When the LED is OFF, the filter is off. When the LED is RED, the filter is in the MINIMALFILTERING or 8dB setting. When the LED is YELLOW, the filter is in the MAXIMUMFILTERING or 14 dB setting.This filter can eliminate unwanted backgrounds noise. By using its internal algorithms,the filter detects repeating noises such as receiver white noise, background rumble, etc., and filtersthem out. The filter processes are NOT recorded by the on-board recorder, however. This retainsthe integrity of the original reception from the receiver. The filter can be used 'live' during receiverreception, as well as during playback of a prerecorded tape. You should experiment with this filterto see what settings you should use to best fulfill your needs.5.) Adjust the VOLUME control to the center position. Alter the volume to operator preferenceonce transmission has begun.6.) Adjust the SQUELCH control fully to the counter-clockwise position. The noise you hearcoming from the audio system is called "White Noise". Turn the squelch control clockwise untilthis white noise just disappears and the audio system is quiet. This is called the "Critical Squelch"point. Critical Squelch is the optimum point of squelch for the system. Squelch may then beadjusted to the operators preference at any time by turning the control clockwise to increase, orcounter-clockwise to decrease the amount of squelch in the circuit.7.) If receiving transmissions from a scrambled TACTICAL TECHNOLOGIES INC transmitter orrepeater, set the SCR switch to ON (corresponding LED is ON). If the transmission is notscrambled, set this switch to OFF (LED is OFF).8.) The Citation will now receive transmissions from your transmitter. Audio will be heardthrough the internal speaker.9.) If you prefer private listening, insert a male stereo phone jack from any stereo headphones orearphone into the EAR jack. This will disconnect the external speaker. The volume control willnow control the audio level in your headphones.RECORDING TRANSMISSIONS1.) Complete the steps outlined above for Receiving Transmissions.2.) Press the STOP/EJECT button to open the CASSETTE TAPE COMPARTMENT. Insert aBULK ERASED blank cassette into the slot on the compartment lid so that the open edge of thecassette faces up and the full reel of tape is toward the left. Close the cassette compartment lid.NOTE: TACTICAL TECHNOLOGIES INC. RECOMMENDS USING A BULK ERASED TAPE ANYTIME THE RECEIVER/RECORDING SYSTEM IS IN OPERATION. A BULK ERASED TAPEASSURES THAT THE CASSETTE BEING USED IN THE OPERATION IS CLEAN AND FREE OFANY UNWANTED PREVIOUSLY RECORDED MATERIAL, AND WILL ASSIST IN ACHIEVINGTHE OPTIMUM QUALITY IN RECORDING OPERATIONS. RECORDING QUALITY WILL VARYHOWEVER DUE TO TRANSMISSION AND RECEPTION CONDITIONS.
93.) Set the TAPE SELECTOR SWITCH found on the left side of the recorder to match with thetype of cassette being used. This selects the proper bias and internal recorder equalization to suitthe most common types of cassette tapes.NORM normal ferric oxide tapesCrO2 chromium dioxide and other tapes requiring 70ms EQ and high biasMETAL metal tapes.4.) Set the RECORD LEVEL MODE SELECT SWITCH on the front panel of the recorder tothe "ALC" position.5.) Set the TAPE SPEED SELECT SWITCH on the front panel of the recorder to either the"LOW" or "STANDARD" position. "STANDARD" position will set tape speed to 1 7/8 IPS andwill give you 45 minutes of recording time per side from a C-90 cassette tape. The "LOW"position slows down the tape speed to 15/16 IPS and will provide 90 minutes of recording time perside from a C-90 tape.NOTE: QUALITY OF THE RECORDING MAY DETERIORATE BY USING THE "LOW" TAPESPEED POSITION.NOTE: DO NOT CHANGE THE SPEED SELECT SWITCH DURING RECORDING!6.) The switch settings on the right side of the Marantz Recorder should be set as follows:a.) INPUT SOURCE : Lineb.) AUTO NOISE CANCELLING - ANC: Normalc.) INTERNAL MIC ATTENUATION: Any position7.) If a Marantz 221 is installed in your Citation, the MONITOR SWITCH found on the front ofthe Marantz may be placed in the SOURCE position to monitor the receiver before it is recorded,or the TAPE position to monitor the signal actually recorded on the tape. When the Monitorswitch is set to SOURCE, howling may occur. At that time, lower the monitoring volume.8.) On the Marantz 221, with the MEMORY REWIND SWITCH set to the ON position, the tapetravel stops when the TAPE COUNTER reaches "999". Reset the tape counter via the buttonfound next to the counter.9.) Press the RECORD and PLAY buttons on the cassette deck simultaneously.10.) Your Citation will now record all transmissions from your transmitter.11.) No record level adjustment is required as long as the REC MODE control on the front panelof the recorder is set to the "ALC" position. Manual operation of the record level is possible byselecting either the "LIMITER" or the "MANUAL" positions.MANUAL RECORDING LEVEL OPERATION: This mode of operation willpermit manual control of the recording level for maximum dynamic range. Set theREC MODE control to the "MANUAL" position. During operation, adjust theMANUAL RECORD LEVEL CONTROL KNOB while watching the VU METERfound on the front panel of the recorder. Ordinarily, the VU meter needle deflection
10should be as large as possible. If the VU meter needle stays on the right side of thescale, the level is too high and results in distorted sound. Conversely, if the VU meterneedle stays on the left side of the scale, the level is too low and a poor signal to noiseratio will result.LIMITER RECORDING LEVEL OPERATION: This mode allows manual settingof the recording level while an internal limiter circuit automatically prevents overloaddistortion resulting from sudden level peaks. Set the REC MODE control to the"LIMITER" position after setting the recording level desired with the control placed inthe "MANUAL" position. See section on "MANUAL RECORDING LEVELOPERATION" for proper procedures.NOTE: TACTICAL TECHNOLOGIES SUGGESTS THAT ALL RECORDINGS BEMADE WITH THE "REC MODE" CONTROL PLACED IN THE "ALC" POSITION.12.) Use the PAUSE key on the cassette deck to temporarily stop the recording. Press it again toresume recording.13.) To end the recording session, press the STOP/EJECT button on the tape deck.14.) If the Citation is equipped with the optional Marantz PMD-650 Mini-Disk Digital tape deck,see the PMD-650 operator's manual for detailed instructions on how to make recording with thissystem.PLAYBACK OF PRERECORDED TAPE1.) Press the STOP/EJECT button on the cassette deck to open the cassette compartment lid.Insert a prerecorded tape into the slot on the compartment lid so that the open edge of the cassettefaces up. Close the cassette holding compartment lid on the deck.NOTE: Be sure to check the setting of the TAPE SELECTOR switch on the left side of therecorder and compare it to the type of cassette you are using.2.) Set the RECD/PLAY switch to the "RECORDER PLAYBACK" position (LED is RED).3.) Set the VOLUME control to the center position.4.) Set the operation of the DSP system.5.) Press the PLAY button on the cassette deck.6.) Your Citation will now play back any prerecorded tape through the internal speaker.7.) Adjust the volume control to operator preference once playback has begun.8.) If you prefer private listening, insert the male stereo phone jack from any headphones orearphone into the EAR jack on the Citation's control panel. This will disconnect the externalspeaker. The volume control will now control the audio level in your headphones.NOTE: The Headphones jack on the front panel of the recorder may also be used for privatelistening of a prerecorded tape through any stereo headphones. To adjust the volume through this
11connection, use the LEVEL control on the front panel of the recorder.9.) Press the STOP/EJECT button to stop the tape.10.) To scan the tape to find a particular selection, use the CUE/FAST FORWARD to fastforward, and the REVIEW/REWIND buttons to rewind the tape. Press the STOP/EJECT buttonto end fast forward or rewind.11.) The tape deck is equipped with a tape search feature that allows you to scan sections of thetape while the deck is in the play mode by partially depressing either the FAST-F or REWINDbuttons. You will hear a loud high-pitched squeal through the audio source if the tape has anything recorded on it. When the tape reaches a blank section, the squeal stops.NOTE: TAKE CAUTION IF USING A HEADSET WHILE OPERATING THE TAPE SEARCHFEATURE - MAKE SURE TO ADJUST THE VOLUME DOWN BEFORE PROCEEDING.12.) The PITCH control found on the front panel of the recorder operates only during playback.This control is used to slightly vary tape speed, thus altering the sound of the prerecorded tape.Normal speed is indicated when the PITCH control is set to the center (click) position.OTHER FEATURES OF THE TAPE DECK1.) The cassette recorder comes with a tape counter to mark the location of a specific section oftape. Press the reset button on the right to set the counter to 000 at the beginning of the tape.Then, as the tape plays or records, note the counter reading at the point(s) to which you want toreturn.2.) NOTE: IT IS ADVISABLE TO USE A BULK TAPE ERASER TO INSURE PROPER ANDCOMPLETE ERASING OF ANY AND ALL TAPES PRIOR TO THEIR USE IN THE CITATION.3.) Cassettes have a built-in device to automatically prevent erasure of a tape by recording over it.THIS PROTECTION DEVICE, HOWEVER, DOES NOT PREVENT ERASURE USING A BULKTAPE ERASER. The cassette has two small plastic tabs on the back edge. If you break off theSide A tab, you cannot record on Side A. There is a separate tab for Side B. If, however, you laterwant to record on a side after you have removed the tab, cover the tab hole with a piece of plasticadhesive tape. CAUTION: Never try to force the RECORD key down if you have removed thetab for that side. You can damage the tape mechanism.4.) Dirt or particles of the tape coating can accumulate on the tape heads and the other parts thatthe tape touches as it moves. This material can greatly reduce the performance of your unit, so youshould clean these parts after every 10 hours of operation.a.) Disconnect any external power source that is connected to the Citation, andmake sure the PWR switch is in the "OFF" position.b.) Press the STOP/EJECT button to open the cassette compartment door.c.) Press the PLAY key. The tape head/motion assembly moves forward intoview. Use a cotton swab dipped in tape head cleaning fluid or denatured alcoholto clean the parts. Clean both the tape heads, the rubber rolling wheels, and thecapstan pin along the rubber wheel. NOTE: Never touch the front surface ofeither of the tape heads with any metallic object.5.) Tape heads and guides also become magnetized over a period of time and should be
12demagnetized periodically using a commercial head demagnetizer.NOTE: PLEASE REFER TO THE OPERATOR'S MANUAL FOR THE MARANTZ RECORDERFOR FURTHER INFORMATIONREMOVING THE TAPE DECK FOR EXTERNAL USEThe Marantz tape recorder can easily be removed from the Citation 20, allowing it to be used in avariety of other recording needs. It is held down to the control panel via four brackets, one oneach side and two in the rear. (For the PDM-650, there are 3 brackets, one on each side and one inthe rear).TO REMOVE THE RECORDER...1.) Turn the Citation 20's POWER switch OFF.2.) Disconnect the three cables leading to the Marantz from the Citation's control panel:a.) RECORDER POWER CABLE connected to recorder's POWER INPUT JACK.When this cable is removed from the recorder, it must be inserted into the RECORDERPOWER CABLE HOLDER grommet .b.) IN cable connected to LINE IN JACK .c.) OUT cable connected to LINE OUT JACK .3.) Completely loosen the two screws found on each of the two side brackets attached to theHOLD DOWN PEGS on the recorder. Turn the screws counter-clockwise to remove them fromthe control panel, but do NOT remove the screws from the brackets.4.) Remove the brackets from the recorder by lifting them up slightly, then sliding them off thePEGS.5.) Gently slide recorder towards the front of the Citation. This will release the two rear holddown brackets which were inserted into the RETAINER SLOTS . Do not loosen or remove thesebrackets from the control panel. (For the PMD-650, this single bracket goes over the top of therecorder).7.) Once the recorder has cleared the rear brackets, lift the unit off the control panel.TO REPLACE THE RECORDER:1.) Align the rear hold down brackets with the RETAINER SLOTS in the recorder and gently slidethe tape deck slots over the brackets. (For the PMD-650, slide the tapedeck underneath thebracket.)2.) Replace side brackets onto the recorder's HOLD DOWN PEGS, and screw brackets onto thecontrol panel. Make sure screws line up exactly with the holes in the panel BEFORE you attemptto replace them. Cross threading these screws may cause damage that will not allow the recorderto be held securely to the control panel. Use a small screw driver to tighten the screws downsnugly to the control panel.3.) Replace all cables into their correct jacks on the recorder.USING THE TWO "DIGITAL AUDIO CONTROL"ADJUSTMENTS
13These controls peak and/or notch higher and lower audio frequencies so that you may tailor theaudio you hear from the receiver or the playback of a prerecorded tape to suit your listening.These digital controls act like a two-band equalizer, and effectively only contour the frequenciesthat are of the utmost importance in the band of audio frequencies that are utilized by humanspeech. They are also optimized to be functional within the narrowed audio bandwidth of theNITA-102 standard.To FLATTEN out the audio response from the DAC adjustments, and remove any peaks or notchesin the audio frequencies, push the RIGHT and/or LEFT ARROW switches until both the top andbottom row of LED indicators are in the CENTER POSITION. To PEAK the upper frequency,repeatedly push the RIGHT ARROW switch on the TOP control and move the LED indicator tothe right of the center position . To NOTCH the upper frequency, use the LEFT ARROW on theTOP control and move the LED indicator to the left of the center position. Repeat this procedureto PEAK or NOTCH the lower frequency.LINE OUTThe female RCA/Phone type LINE out jack gives an additional line level output from the receiverfor use with an external tape recorder, external audio amplifier, equalizer, etc.RSSI /BATTERY STRENGTH INDICATORThe BAT/RSSI (RSSI/BATTERY STRENGTH) switch and indicator located to the right of thekeypad, can supply the user with an RSSI reading (Received Signal Strength Indicator) from anoperating transmitter, or it can show the condition of the internal battery inside the Citation.TO MEASURE RSSI.....1.) Tune the receiver to the operating frequency of a active transmitter.2.) Push the BAT/RSSI button until the LED indicator is RED.3.) The LED METER above the indicator and to the right of the LCD Display will change incolor (Red is weakest, Yellow is mid, and Green in the highest quality) and increase in heightthe stronger the incoming signal is. The weaker the signal, the lower the meter reading willbe.Meter Reading Examples:Meter @ MID RED Usable signal - may be slightly noisy.Meter @ BOTTOM YELLOW Incoming signal should open the receiver at critical squelch point.Signal is approximately 0.2 microvolts.Meter @ MID GREEN Incoming signal should open the receiver at its fullsquelch point (control set fully clockwise). Signal is approximately1.0 microvolts.The purpose of the RSSI meter is to give a visual indication of how to achieve better reception viareceiver antenna configuration and placement. In order to improve signal reception:a.) When using the Internal Antenna, rotate the Citation in a circular pattern to increase the
14received signal to its best point.b.) With an External Antenna, physically move the antenna's placement. If the antenna isinstalled on a vehicle, move the entire vehicle to achieve better RSSI.It is important to remember that ANY increase in the meter reading, no matter how little, will be amarked improvement in signal strength. The majority of movement in the meter during the courseof a normal operation will be between 0.5 and 3 on the meter scale. That relates to approximatelya 1 microvolt swing in reception. And every 1/10 of a microvolt increase in signal is a significantimprovement. While it is true that the better the signal the more the needle will move toward theright of the scale, the needle does not have to move very far to the right to reflect a change in asignal from one that is "in the mud" and unusable to one that is intelligible, and then to one that iscrystal clear.TO MEASURE THE INTERNAL BATTERY CONDITION....Press the BAT/RSSI switch until the LED indicator is YELLOW. The meter scale reflects thefollowing information:METER READS.. BATTERY VOLTAGE IS.. DESCRIPTIONBottom RED Less that 9.7 VDC Unit in Shut Down ModeTOP RED 9.7 to 11.5 VDC Low Battery ConditionYELLOW 11.5 to 13.8 VDC Normal Operating RangeGREEN 13.8 to 14.4 VDC Full ChargeCHARGING and CARING FORTHE INTERNAL BATTERYThe Citation 20's internal battery is charging whenever the unit is connected to 110 VAC. The unitwill charge with the POWER switch ON or OFF. If the Citation's POWER switch is ON and theunit is operating, the battery will charge at a slower rate than if the POWER switch is OFF.The Citation 20 WILL NOT charge during external 12 VDC operation.Low battery condition is indicated on the Citation 20 via the RSSI/Battery Condition meter. Themeter will read in the RED LED SEGMENTS - or towards the BOTTOM YELLOW SEGMENTS(See the section on the RSSI/Battery Meter for complete meter operating instructions). Once theBAR GRAPH LED begins to turn to the bottom Yellow segments, plan to change your powersource to either external 12 VDC or 110 VAC to ensure non-interrupted operation. A fullycharged battery will supply an average operating time of 6 hours. Operating time will vary due tothe length of time the recorder is in operation.Once the unit enters a low battery condition, it will continue to operate for at least one hour - thenthe Citation 20 will shut off completely.The internal battery must be fully charged immediately once the unit has either entered the lowbattery condition, or if the unit has shut down due to the battery being fully depleted.NOTE: IF THE CITATION 20 REACHES THE "SHUT DOWN" POINT, IMMEDIATELY PLUGTHE UNIT INTO 110 VAC, TURN THE POWER SWITCH OFF, AND RECHARGE THEBATTERY. IF THE POWER SWITCH STAYS IN THE ON POSITION AND THE CITATION 20 IS
15NOT CONNECTED TO 110 VAC, THE UNIT WILL CONTINUE ATTEMPTING TO DRAW ASMALL AMOUNT OF CURRENT OFF THE INTERNAL BATTERY, EVEN THOUGH THERECEIVER WILL BE NONOPERATIONAL. THIS MAY PERMANENTLY DAMAGE THEINTERNAL BATTERY AND WILL VOID THE UNIT'S WARRANTY.The internal battery should also be "cycled" at a minimum of once every month. Cycle the batteryby allowing the Citation to operate until the BATTERY LED BAR GRAPH begins to turn RED,indicating that the battery is low. Then charge the battery for a minimum of 10 hours. By cyclingthe battery, you will insure proper operation and increase the battery life.NOTE: DO NOT CHARGE THE INTERNAL BATTERIES IN THE CITATION 20 FORMORE THAN 24 HOURS DURING EACH CHARGE CYCLE. CHARGING FOR LONGERTHAN 24 HOURS MAY CAUSE DAMAGE TO THE INTERNAL BATTERY.THE LAMP AND LCD BUTTONSThe LCD button controls the internal light on the LCD display. This switch toggles the internallight ON or OFF.The LAMP bottom controls the illumination of all the other LED's on the panel. This switchtoggles all the panel LEDs (including the Bar Graphs) ON or OFF. The only exception to this isthe LED inside the POWER switch. The LAMP switch toggles this LED between VERY BRIGHTand VERY DIM.OPERATING NOTES:1.) Keep the Citation dry. If it does get wet, wipe it dry immediately. Liquids might containminerals that can corrode the electronic circuits and cause extensive damage.2.) Handle the Citation with care. Dropping the unit may damage circuit boards, the recorder, andthe case, rendering the unit inoperable.3.) It is advisable under extended storage conditions that the Citation's internal battery be allowedto fully discharge down to the low battery indication and then be immediately fully rechargedbefore the Citation is stored again. This procedure should be carried out once every month.Following this system will allow the battery to completely cycle, thus lengthening battery life.The life of the battery may shorten if the Citation is stored for an extended period of time withoutuse. Do not charge the battery for more than 24 hours per charge cycle.4.) Be sure to install the mag-mount antenna base on a metal object when in use. This will allowfor proper operation of the antenna system, giving the operator the best possible performance fromthe receiver.5.) There are no user-serviceable parts in the Citation. If for some reason the unit needs service,please return it to the factory.6.) In cassette recording, the type and brands of cassettes you use have a great influence on thequality of your recordings. Therefore, it is advantageous to purchase the highest quality cassettesavailable. Chromium dioxide (CrO2) and metal tapes generally provide better fidelity than normalferric oxide tapes.
