Cirrus DesignSR20Section 9Supplements Right Outer Knob – Copilot and passenger mic VOX level. CWrotation increases the amount of mic audio (VOX level) requiredto break squelch. Full CCW is the ‘hot mic’ position.Each microphone input has a dedicated VOX circuit to assure that onlythe active microphone(s) is/are heard when squelch is broken. Afterthe operator has stopped talking, the intercom channel remainsmomentarily open to avoid closure between words or normal pauses.ControlThe Audio Control Panel provides an adjustable Voice Operated Relay(VOX) Squelch Control for the pilot, copilot, and passengers. Since theVOX circuits reduce the number of microphones active at any onetime, the amount of unwanted background noise in the headphones isdiminished. This also allows the use of dissimilar headsets with thesame intercom. Because the user can adjust the trip level of the VOXsquelch to fit the individual voice and microphone, this helps eliminatethe frustration of clipping the first syllables. There is a slight delay aftera person stops talking before the channel closes. This preventsclosure between words and eliminates choppy communications.To adjust squelch:1. With the engine running, set the VOX trip level by slowly rotatingthe SQL control knob clockwise until you no longer hear theengine noise in the headphones.2. Position microphone near your lips and speak into microphone.Verify that normal speech levels open the channel.Intercom ModesThe GMA 340 provides three intercom (ICS) modes to further simplifyworkload and minimize distractions during all phases of flight: PILOT,CREW, and ALL. The mode selection is accomplished using thePILOT and CREW push-buttons. Pressing a button activates thecorresponding ICS mode and pressing the button a second timedeactivates the mode. The operator can switch modes (PILOT toCREW or CREW to PILOT) by pressing the desired modes push-P/N 11934-S01Revision 02: 07-18-057 of 10

Section 9SupplementsCirrus DesignSR20button. ALL mode is active when neither PILOT or CREW have beenselected.PILOTThe pilot is isolated from the intercom. The pilot can hearradio and sidetone only during radio transmissions. Copilotand passengers can hear the intercom and music but not theairplane radio receptions or pilot transmissions.CREWPilot and copilot are connected on one intercom channel andhave exclusive access to the aircraft radios. They may alsolisten to Music1. Passengers can continue to communicatewith themselves without interrupting the Crew and also maylisten to Music2.ALLAll parties will hear the aircraft radio, intercom, and Music1.The music volume increases gradually back to the originallevel after communications have been completed. Both pilotand copilot have access to the COM transceivers.The following table shows, in abbreviated form, what each occupanthears in each of the selectable Intercom modes:ModePilot HearsCopilot HearsPassenger HearsPILOTA/C tMusic1CREWA/C RadiosPilot/CopilotMusic1A/C RadiosCopilot/PilotMusic1PassengersMusic2ALLA/C RadioPilot/CopilotPassengersMusic1A/C Radio Pilot/CopilotPassengersMusic1A/C RadioPilot/CopilotPassengersMusic1Marker BeaconThe Marker Beacon Receiver provides visual and audio indicators toalert the pilot when the airplane passes over a 75 MHz transmitter.Marker beacon controls and lights are located at the extreme left of theAudio Control Panel.8 of 10P/N 11934-S01Revision 02: 07-18-05

Cirrus DesignSR20Section 9SupplementsMarker beacon audio is selected by pressing the MKR push-button. Ifno marker beacon signal is being received, pressing the MKR pushbutton a second time deselects marker beacon audio. However, ifmarker beacon is being received, pressing the MKR push-button asecond time will mute the audio but the light will continue to flash.Pressing the MKR push-button a third time (while marker beaconaudio is muted) deselects marker beacon audio. Marker beacon audiomuting automatically disables when the current signal is no longerreceived. Note The marker beacon lamps (O, M, A) operate independently ofthe audio and cannot be disabled.Marker beacon light and audio keying for ILS approach aresummarized below:O (Blue)Outer Marker light and associated 400 Hertz tone. Thelight and tone are keyed at a rate of two tones/flashes persecond.M (Amber)Middle Marker light and associated 1300 Hertz tone. Thelight and tone are keyed alternately with short and longbursts.A (White)Airway/Inner Marker light and associated 3000 Hertztone. The light and tone are keyed at a rate of six timesper second.Marker Beacon SensitivityThe SENS push-button on the left side of the panel is used to set themarker beacon receiver sensitivity. The selected sensitivity level isindicated by illumination of the HIGH or LOW LED. When HIGHsensitivity is selected, the outer marker beacon tone will sound fartherout. Selecting LOW sensitivity at this point allows more accuratelocation of the Outer Marker. Typically, HIGH sensitivity is selecteduntil the outer marker tone is heard, and then LOW sensitivity isselected for more accurate outer marker location.P/N 11934-S01Revision 02: 07-18-059 of 10

Contact XM Satellite Radio at800.985.9200 for subscription information.The optional XM Radio System provides satellite broadcast audioentertainment and information to aircraft occupants via the GarminGMA 340 Audio System while traveling anywhere within thecontiguous United States of America.The XM receiver, installed in the co-pilot side of the center console,receives audio information via its integral antenna from twogeosynchronous XM broadcast satellites. The audio signal is then sentby wire to the Audio Control Panel’s Music1 and Music2 AUDIO INPUTjacks. System operation is provided by a hand held, wirelesscontroller. When initially powered, the XM radio volume is set to mute andwill remain muted until the XM radio establishes communicationwith the wireless controller. System volume for both AUDIO INPUT jacks is controlledsimultaneously via the wireless controller. In the event of wireless controller failure during flight, cyclingthe Weather/Stormscope circuit breaker will reset the volume tomute. XM radio is the default audio heard on the AUDIO INPUT jacks.If a personal entertainment device such as a CD player isplugged into either AUDIO INPUT jacks, the external source willoverride the XM audio signal. Refer to the Intercom ModesTable presented above for a description of intercom modes.The XM Radio System is powered by 28 VDC supplied through the 3amp Weather/Stormscope breaker on the Non-Essential Bus.10 of 10P/N 11934-S01Revision 02: 07-18-05

For a detailed description of the GTX 327, refer toGARMIN GTX 327 Mode A/C Transponder Pilots Guide, p/n190-00187-00 September 2011 (Feb 2000) or later revision.The Garmin GTX 327 transponder system consists of the integratedreceiver/transmitter control unit, an antenna, and an altitude digitizer.The receiver/transmitter receives interrogations from a ground-basedsecondary surveillance radar transmitter and then transmits to theinterrogating Air Traffic Control Center. Digitized altitude information isprovided by the altitude digitizer (encoder) plumbed into the airplanestatic system. The transponder and integrated controls are mounted inthe center console. The transponder control provides active codedisplay, code selection, IDENT button, and test functions. The displayis daylight readable and is automatically dimmed through a photocell.The controller buttons are dimmed through the INST lights control onthe instrument panel bolster. The transponder antenna is mounted onthe underside of the fuselage just aft of the firewall. 28 vdc fortransponder operation is controlled through the Avionics MasterSwitch on the bolster switch panel. 28 VDC for receiver, transmitter,and altitude encoder operation is supplied through the 2-ampENCODER/XPONDER circuit breaker on the Avionics Essential Bus.4 of 8P/N 11934-S12Original: 12-26-00

Cirrus DesignSR20Section 9SupplementsMode Selector KeysThe mode selector keys are located in a circular arrangementimmediately to the left of the display window. The selected mode isannunciated at the left side of the display immediately adjacent to theselector keys. The five positions are:OFF - Turns off all power to the GTX 327 transponder. Thetransponder should be off until the engine is started. Normally, thetransponder can be left in the STBY position and allow the AvionicsPower Switch to control system power.STBY - Powers the transponder in standby mode. The last activeidentification code will be selected. In STBY, the transponder will notreply to any interrogations from an ATC secondary ground surveillanceradar system. This is the normal position for ground operations in theSR20. Note STBY mode is automatically entered from ALT mode duringlanding ground roll as the groundspeed decreases through 35knots.ON - Powers on the GTX 327 in Mode A (identification mode.). Thelast active identification code will be selected. In addition to theairplane’s identification code, the transponder will also reply to altitude(Mode C) interrogations with signals that do not contain altitudeinformation.ALT - Places the transponder in Mode A and Mode C, identificationand altitude respectively. The transponder will respond tointerrogations with the airplane’s identification code and standardpressure altitude (29.92 inches Hg). Note ALT mode is automatically entered from STBY mode duringtakeoff ground roll as the groundspeed increases through 35knots.P/N 11934-S12Original: 12-26-005 of 8

Section 9SupplementsCirrus DesignSR20Code Selector KeysCode selection is accomplished by depressing the eight selector keys(numbered 0 - 7) located immediately below the display. Any of 4096active identification codes can be selected. The selected code must bein accordance with instructions for IFR flight or rules applicable totransponder utilization for VFR flight.The airplane’s transponder code is used to enhance tracking capabilityby ATC. Therefore, do not switch the transponder to STBY whenmaking routine code changes.Input a New Code1. Use CLR key to remove the current code.2. Use “0 - 7” keys to input the new code. The new code will not beactivated until the last (fourth) digit is entered. Pressing the CLRkey will move the cursor back to the previous digit. Pressing theCRSR key during code entry will remove the cursor and cancel theentry. Note When making routine code changes, avoid inadvertentselection of code 7500 and all codes within the 7600 series(7600 – 7677) and 7700 series (7700 – 7777). These codestrigger special indicators in automated facilities. 7500 will bedecoded as the hijack code.Important Codes 1200 – VFR code for any altitude in U.S. 7000 – VFR code commonly used in Europe 7500 – Hijacking 7600 – Loss of communications 7700 – Emergency 7777 – Military interceptor operations (Never squawk this code) 0000 – Military use only (not enterable)6 of 8P/N 11934-S12Original: 12-26-00
