EL 22759 16 22 White Wire 8 0 CALIBRATION OF INSTALLATION Please refer to the Civil Aviation rules or regulations for your country to determine the calibration requirements for a transponder installation Most countries will require a test of the installation to be carried out by a qualified test centre along with a calibration of the encoder and altimeter in the aircraft Microair Avionics recommends the use of certified altimeters for operation with transponders and encoders This test or inspection is usually required every two years If the installation is in a non certified aircraft the test and calibration is not exempt The installation must be proven compatible with the ATC SSR system before operation regardless of the aircraft type 9 0 WARRANTY CARD Please complete and return the yellow warranty card to Microair Avionics The warranty period is 12 months from the date of sale however Microair Avionics will honour the warranty as twelve months from the date of installation where the installation was carried out by an approved installer avionics shop and the card is dated and signed by the installer If you have misplaced the card please use the warranty registration form on the Microair Avionics website www microair com au For full details of the warranty please refer to the T2000 User Manual inside rear cover T2000 installation manual V23 doc Page 9 of 12 23 August 2003 Microair Avionics T2000 Transponder
