Buffer Altitude
The user can input a buffer altitude, above and below the assigned
altitude, to define a height band in which to fly. When the aircraft
exceeds the upper or lower limit, an indicator alert message will be
displayed. The alert message advises the pilot of how far, above or
below the assigned altitude the aircraft is. If the Alert Tone function is
ON, an audio tone is heard as well. If the ALTITUDE option in the
PROGRAM MODE is set to FEET or FL, the Buffer Alt increments are
in feet. If ALTITUDE is set to METRES, the Buffer Alt increments are in
metres.
Press MODE key (3 times) to select Buffer Alt option
Press CODE SELECT knob tn increment in units of 500 feet/100m
Rotate CODE SELECT knob to increment in units of 100 feet/10m
Press ENTER key to return display to current operational display
For example, with the Assigned altitude set at 3500 feet, and the Buffer
All set at 200 feet, the display alerts will occur over 3700 feet and under
3300 feet. If the aircraft climbs or descends outside the altitude buffer
limits, a Hi / Lo warning is displayed on the lower line.
Altitude
The altitude data can be displayed as feet, flight level, or metres. Once
the Altitude units are set, all altitude data is displayed in these units.
The options are: F = FEET FL=FLIGHT LEVEL M = METRES
The only exception is when the Altitude is set to FL, the Buffer Alt is still
displayed and set in FEET.
Press MODE key (4 times) to select Altitude option
Rotate CODE SELECT knob and scroll to select desired units.
Voltage
The VOLTAGE function will display the aircraft’s supply voltage, and
rotating the CODE SELECT knob, display the over/under voltage alerts.
Press MODE key (5 times) to select VOLTAGE option
Rotate CODE SELECT knob aircraft volt is displayed
Rotate CODE SELECT knob to display high set point
Rotate CODE SELECT knob to display low set point
Rotate CODE SELECT knob to display receive signal strength
Rotate CODE SELECT knob to return display to input voltage
When the transponder is operating in normal display operation mode, the
over and under input voltage alert message is displayed on the lower line.
Alert Tone
The Alert Tone function is used by the T2000's altitude alert function.
When set ON, the Alert can be heard from either the cabin speaker, or
through the headphones, when amplified through an audio panel.
Press MODE key (6 times) to select Alert Tone option

ENTER KEY
The ENTER key is a confirmation key used to confirm information the user has input. After
pressing the ENTER key, the display will typically give the message SAVED for a short period.
TOGGLE KEY
This key acts as a TOGGLE switch, exchanging the active and standby codes. When the
transponder is operating in DISPLAY ALT the bottom line displays the Encoder altitude
instead of the standby code. To toggle the active and standby codes in this mode, push the
TOGGLE key once to display the standby code on the bottom line. The standby code is
displayed for 10 seconds. Push the TOGGLE key again to exchange the active and standby
codes. Once the codes have been exchanged, the display will revert back after 10 seconds to
displaying altitude on the bottom line.
VFR – HOT KEY
THE VFR key will default the standby code (1200) .immediately to the stored VFR code. To
transfer the VFR code to the active position, press the TOGGLE key. If no code is entered,
after 10 seconds idle the standby position will revert back to the original VFR code.
ID KEY
The ID key (IDENT) sends additional code information to the transmission for ATC.
SELECTMODE KNOB
The SELECTMODE knob switches the transponder between the 4 operating modes
STANDBY
In standby the transponder is powered up, but will not transmit.
On the
active display line the letter S appears on the left hand side.
ON
Will reply to Mode A and C interrogations, but with no mode C encoder
information.
On the active display line the letter A appears on the left
hand side.
ALT
Will reply to Mode A and C interrogations, with the mode C encoder
information.
On the active display line the letter C appears on the left
hand side.
ALT DISPLAY The standby code is replaced with the encoder altitude. If the pressure
has been set via the QNH/Baro option of MODE MENU, the displayed
altitude will be adjusted for barometric air pressure. Altitude will be
displayed in units set in ALTITUDE option of MODE MENU. The
DISPLAYALT only displays altitude if a valid encoder input is received.
On
the active display line the letter C appears on the left hand side.
CODE SELECT Knob
The CODE SELECT knob can be rotated clockwise to scroll upwards, and counter-clockwise
to scroll downwards. Each digit of the code is adjusted separately. The adjust function starts
with the left hand digit, and is moved across to the next digit by pushing the CODE SELECT
knob inwards. After 10 seconds of inactivity the cursor will revert to the left hand digit.
