Connect supplied power cable to 12v DC Source (Trailer battery or equivalent). It is not recommended to charge battery or have generator running while system is in use. If generator is used, high voltage transient Solid black wire suppression equipment connected in line is recommended. NEGATIVE Black with white stripe wire is POSITIVE *IMPORTANT*...
Press “MENU” key to turn unit on. Unit will automatically turn off after 2 minutes if no keys have been pressed. GREETING MESSAGE The PerformAIRE By ALTRONICS O2 EQUIPPED VERSION 2.* "O2 EQUIPPED" will only appear if the unit was purchased with an oxygen sensor.
MENUS MAIN MENU - When unit is turned on the MAIN menu automatically is displayed after the greeting message. The user can make one of the nine following choices at this point: SAMPLE AIR = 1 (Current Data) SET UP RUN ENTRY PREDICT Hit the “MENU”...
SAMPLE AIR By pressing "1" (SAMPLE AIR) from the MAIN menu the unit displays all the sampled air parameters and the PREDICTION in the following format: DATE TIME TEMP HUMIDITY PRESSURE OXYGEN (if equipped) ALTITUDE PREDICTION (ET or TS) After 2 seconds the following is displayed: DATE TIME WIND SPEED...
SET UP By pressing "2" from the MAIN menu the unit enters SET UP. Set up allows for configuring any one of the 10 data bases or selecting weather variables to be displayed. Each data Base hold 40 runs. The first menu appears... Setup Data Base =1 Setup Weather =2 Setup Weather:...

next letter. When all the letters have been selected press the “ENTER” key to save the name. After selecting a data base the following is displayed: ET MODE TS MODE Press 1 OR 2 By pressing "1" sets the unit to the ET MODE. This means all runs added to the data base will be stored in the ET section and the PREDICTION will be an ET computed from the stored runs and the present ALTITUDE.
ADR=3 VP=4 Now you must choose which weather variable to reference your prediction against. The standard is to use DA or OA (if the unit is oxygen sensor equipped), but you can select ADR or VP if you wish. One Run: When One Run prediction method is selected you must set your base run and performance ratios.

After pressing the ENTER key (from above) the following will be displayed: PREDICT WITH DENSITY ALT = 1 OXYGEN ALT = 2 PRESS 1 or 2 If your unit has the optional oxygen sensor you can choose to predict your ET or TS value with density altitude or oxygen altitude.
RUN ENTRY By pressing "3" (RUN ENTRY) from the MAIN menu the unit displays the following: VIEW/DELETE RUNS ADD RUNS RATIO/SLET “TSR” (throttle stop ratio) is only displayed if the unit in TS MODE and more then two runs have already been stored. Pressing "3" displays the throttle stop ratio.

Enter Run Info-> DA=1000 (Example) 1000’ ET= The DA or OA will already be loaded. You should enter a 1000’ ET, a final ET, and TS. The 1000’ ET is optional and is used for run completing. You do not have to enter every run with a 1000’ time in order to use run completing.
RUN COMPLETION In order use the run completion program effectively at least one previous run must be entered into a database with a 1000’ ET. To use run completion all you need to do is enter the 1000’ et of the run you want to complete and then when it asks you to enter your final ET= simply press the enter key without any value.
DOWNLOAD By pressing “5” you will begin downloading into a personal computer if you have purchased that option. To install software: Place DISK 1 in drive a:\ and run SETUP. Follow the instructions on the screen to finish installation. COMPORT button - To download PerformAIRE connect supplied cable to unit and to serial port on back of computer.

SET CLOCK By pressing "6" from the MAIN menu the unit will prompt you to enter the DATE and TIME. BAD RUNS By pressing “7’ from the MAIN menu the unit will display any runs that do not “fit” with the rest of the data. These runs will not be removed; you will have to clear them out of the database yourself.
PAGER SETUP By pressing “9” you will the following will be displayed. Enable Pagers XMIT TIME XMIT DATABASES = 3 Selecting “1” displays: HOW MANY?_ Enter the number of pagers that are being used with the system. Enter CAPCODE#1= 0996151 Enter the 7-digit pager capcode found on back of pager.
