The pilot mustmust

must understand the operation and limitations of this product before flying the aircraft. Do not
allow anyone to operate the aircraft that does not know how to properly interpret and operate this product.
Keep the Operating Instructions in the aircraft at all times. If you do not thoroughly understand the
operation of this product, contact a knowledgeable flight instructor for training.
The ability for this product to respond to an engine or aircraft system anomaly is directly related to how
that anomaly affects the reading of the function(s) being monitored (i.e.; if an engine fire does not affect
the EGT or CHT, the EGT and CHT readings will not change).
This instrument only displays the parameters for the function(s) being monitored. The pilot is responsible
for interpreting the data and determining if an engine or aircraft system anomaly exists. When using this
instrument, the pilot’s diagnostic ability is limited to his/her interpretation of the displayed data and the
their observation skills. To improve these skills the pilot should seek training from a flight instructor.
If after reading this manual you do not have the knowledge to interpret the displayed data to operate the
aircraft safely or to detect engine and/or aircraft system problems, contact a knowledgeable instructor for
training prior to flying the aircraft with this instrument.
If you detect a problem using this instrument, it is your responsibility to take appropriate action to ensure
the safety of the flight. Practice simulating problems to build your skills and to improve your understand
of the relationships between problems and their affects on the displayed data. To ensure you are taking
appropriate action, contact a knowledgeable flight instructor for training. Inappropriate action can lead to
aircraft and/or engine damage, personal injury or death.
This manual does not make any recommendations as to specific operating parameters or controlling
methods. Check the airframe and/or engine manufacturer’s recommendations to properly operate the
aircraft systems and engine. It is the pilot’s responsibility to operate the engine and aircraft safely.

your aircraft safely in spite of an instrument failure. If you do not have this knowledge, contact the FAA
or a knowledgeable flight instructor for training prior to flying the aircraft with this instrument.
Electronics International Inc. is not liable or responsible for a pilot’s action or any situation that results in
personal injury, property damage, missed commitments, lack of use of an aircraft or any expenses
incurred due to: product failure, inaccuracy in displayed data or text files, display or display format
issues, software bugs or problems, upgrade or customization issues, misinterpretation of the display,
warning and/or limit settings, calibration problems, installation issues (leaks, mis-wiring, obstructions,
damage to aircraft or components, incorrect installation of any parts, wrong parts, parts that don’t fit,
etc.) or any other issues related to the installation or operation of this product. All of the above are
solely the pilot’s and/or installer’s responsibility. The pilot mustmust
mustmust
must understand the operation of this prod-
uct before flying the aircraft. The pilot must not allow anyone to operate the aircraft that does not know
the operation of this product. The pilot must keep the instrument Operating Instructions in the aircraft at
all times.
Set a unique password to protect all of the calibration and setup data in the CGR-30P. If setup or calibra-
tion data is inadvertently or improperly changed, you could get inaccurate readings that may lead to
improper operation of the aircraft or engine. This could result in engine damage and/or an emergency
situation.
Before flying the aircraft verify that the instrument markings displayed on the CGR are accurate with
your POH for every function displayed on the CGR.
The CGR must be calibrated to the aircraft fuel system and the CGR's accuracy must be verified before
flying the aircraft.

FuelData Screen (see section5.0): The Fuel Data Screen provides
sixsets ofdata basedon Fuel Flow and GPSinformation. This data
includesRange,DistancetoDestination,Rangeafterreachingyour
Destination,FuelRemaining,FueltoDestination,FuelReserve,Timeto
Empty,TimetoDestination,TimeReserve,FuelUsedfor theFlight,Fuel

Muchof this datadepends on anRS232 connection toyour GPS.
User Setup Screens (see section 6.0): The User Setup Screen Menu
providesa listof setupscreens forsetting theK-Factor, settingclocks,
viewingtheTachandEngineHours,setting thedisplayrangeforthe bar
graph,downloadingrecorded data andsettingup theRecurringFuel
Alarm.
SystemConfigScreens(seesection7.0): The System Config
ScreensallowsElectronicsInternational tosetupthe CGR-30P foralmostany function foranyaircraft. These
screens are password protected.
1.3 System Hardware:
TheCGR-30Phardwareconsists ofthefollowingthree groupsofcomponents:
A. Probes,TransducersandExtensionCables–These components are used to measure pressures,
temperatures,fuelflow,volts,amps,fuellevelsandmany other engineandaircraftsystemfunctions. The
analogsignals produced bythe transducersand probesare routedthrough the ExtensionCables to
variousEDCinputs.
B. EDC(Engine DataConverter)– The EDC-33Pconverts the analogsignals from theprobes and
transducersto adigital format. This datais transmittedvia aone-wire +5VSerial cableto theCGR
Display.

Fuel Data Screen

C. CGRDisplay – The CGR receives, processes and displays the Serial EDCdata on its TFT color
display. Inaddition, theCGR receivesGPSdata, interfaceswith theVoiceWarningControl Paneland
monitorstheexternal backlightcontrol line. Also,theCGR transmitsfueldata totheGPS andcontrols
theexternalCautionandWarningLights.
TheCGR reducesthe number ofpanel-mounted instrumentsfrom around12 toonly 1. TheEDC canreduce the
totalnumberof wiresrouted totheaircraft instrumentpanel by 50or more.
1.4 SELECT Knob and Button Operation:
SELECTKnob: The SELECT knob can be rotated or pressed.
Dependingonthe screen andfieldbeing viewed,rotatingthe knob can
moveanarrow,select adigit, orchange a digit’svalue. Pressing the
SELECTknobwillchoosethehighlighteditem.
SCREENSButton: Pressing theSCREENS button sequencesthe
CGRthrough the fourdisplay screens(Main, Secondary,Fuel Qtyand FuelData).
EXITButton: Pressingthe EXITbuttonwill exityouout ofa specific operation. Repeatedpresses willexityou
outof thecurrent screenand return you to theMain Screen.
1.5 Display Dimming:
TheCGRprovides anexternaldimming controllineto dimthedisplay. TheCGRcan beset to dimon any input
voltageswing. Dimmingcalibrationissetupinthe Display &VoiceControlsscreenfound in section7ofthis
manual.
1.6 Cleaning the Screen:
TheCGR incorporates aflat panelfull colorTFTdisplay,whichshould beprotected fromscratches. TheTFT

SELECTknob maybe usedto changeoperating modes.
2.5.1 “EGT/CHT”Operating Mode: The vertical barsare arranged to show the EGT and CHT for
eachcylinder. Theoperating rangesfor theEGTbars maybe settomatch yourengine’s operating
temperatures(i.e.;if yourfull richlowpower EGTreadingsare around 1100’F, setyour LowEGTRange
for1000’F. Ifyour peak EGTreadings are around 1500’F,set your High EGTRange for 1525’F). The

2.5.2 “Normalized”OperatingMode: TheNormalized Modeof operationis anengine diagnostictool
thatallowscomparisonof thecurrentEGTsandCHTsto areference(past flight). By normalizingtheEGTs
