8. June 2002 Microair Avionic T2000 Transponder User Manual Q I have noticed that sometimes when I switch on the Avionics Master switch the T2000 turns on by itself without pressing the ON key Why The T2000 s ON key is software controlled The T2000 will remember if it was on or off When the power is turned on again the T2000 will revert to its last operational condition and turn on In normal operation we advise using the on off button on the T2000 to turn the unit off before switching off the master This will give the T2000 protection against possible voltage surges when the master is turn on again In some installations however the use of an avionics master tends to make this process obsolete for some we still recommend turning it off and on via the T2000 on off button Whilst flying outside normal radar coverage I have noticed that the reply symbol still flashes from time to time what causes this Other aircraft fitted with TCAS systems can still interrogate non TCAS equipped aircraft like yours This then lets them know where you are and is displayed on their TCAS screens The TCAS aircraft could be 100 or more miles away and at altitudes 30 000ft I have tried to power up my T2000 on the bench from a de power supply but 1t won t start up properly What is going on The T2000 has a number of large capacitors fitted and at the moment of turn on they will try to charge up When this happens an in rush of
