- Page 2 The T2000SFL owner accepts all responsibility for obtaining the proper licensing before using the transponder. The coverage you can expect from the T2000SFL is limited to “line of sight”. Low altitude or aircraft antenna shielding by the aircraft itself may result in a reduced range. Range can be improved by climbing to a higher altitude. It may be possible to minimize antenna shielding by locating the antenna where dead spots are only noticed during abnormal flight attitudes.

Page 4: Introduction
User Manual 1.0 INTRODUCTION The Microair T2000SFL Transponder is designed to operate in the environment of a Radar Beacon System. This system interrogates the transponder, which in turn replies with an identity code and altitude information. The radar system consists of a network of ground stations, which sweep the horizon like a conventional radar. When the transponder in the aircraft detects the radar sweep (is illuminated), the transponder replies with a burst transmission giving its identity code and altitude. -

3.3 ON KEY The T2000SFL is turned on by pressing the ON key. The T2000SFL then performs a self test before moving on to the operational screen, in whatever mode the select mode knob is set to. This test sequence includes the display of the serial number and the firmware version. -
Page 10: Mode Key
The MODE key can be used to access two separate menus: Mode Key • If the transponder is turned on, by holding down the MODE key, and pressing the ON key, the T2000SFL will start in PROGRAM MODE. The MODE key must be held down, until the start-up self-test messages have been displayed. -
Page 11: Qnh Or Baro (Barometric Pressure)
This means the encoder altitude may not be the same as the altimeter reading. The QNH / Baro can be entered here to allow the T2000SFL to compensate the displayed altitude for surface pressure, and hence read the same as the aircraft’s altimeter. The default QNH is 1013mb or Baro is 29.92HG. -
Page 12: Assigned (Altitude)
Press the Toggle key to save the height value, and return to the operational display. If Assigned is set to 0, the altitude alert function is disabled. The assigned altitude function is only active when the SELECTMODE knob is set to DISP ALT. T2000SFL User Manual 01R8-2 Page 12 of 28 September 2012... -
Page 13: Buffer Alt
If the aircraft climbs or descends outside the altitude buffer limits, a Hi / Lo warning is displayed on the lower line. T2000SFL advises the pilot that the aircraft is 500 feet above the Assigned altitude. If the Alert Tone function is set on, an audio warning tone is heard. -

Page 21: Altitude (Units)
4.1.4 BARO This item sets the barometric pressure units used by the T2000SFL. The user can select from MB = millibars, or HG = inches Mercury. We recommend that the user selects the same units as those used in the sub-scale of the aircraft’s altimeter. -
Page 22: Rem Stby
The user can exit the PROGRAM MODE menu at any time, from any menu item, by pressing the toggle key. To re-enter the PROGRAM MODE menu the T2000SFL must be turned off, and re-started using the ON and MODE keys (refer PROGRAM MODE section). -
Page 23: Frequently Asked Questions
The following questions are common to most users and may help you understand the operation of the T2000SFL, some of these are explained in the user manual but may have been missed by the reader: When I am asked to Squawk Ident ( ID ) the I indicator stays on for a long time. Why ??? The I or ident character, is used to denote that the transponder reply now includes the ident information, to make the return flash on the ATC display. - Page 24 The TCAS aircraft could be 100+ miles away and at altitudes +30,000ft! I have tried to power up my T2000SFL on the bench from a dc power supply, but it won’t start up properly. What is going on ? The T2000SFL has a number of large capacitors fitted, and at the moment of turn on they will try to charge up.
- Page 25 Is there anything inside the T2000SFL transponder I can adjust to get better performance ? No. Do not open the T2000SFL, or attempt to adjust any internal components. Service should only be carried out by Microair Avionics or a certified avionics service centre which holds the T2000SFL Service Manual.
