Envelope Temperature Display (Env Temp); Pairing To A 3040 - Flytec 3040 Operation Manual

7.2.1

Envelope Temperature Display (ENV TEMP)

The 3040 will only receive data from a TT34 if the receiver (REC) switch is in the ON position.
Since the internal receiver is switched off when the main power switch is off, it is recommended
Maximum in-flight temperature: To see the maximum envelope temperature of a flight, switch
off the receiver. The arrow indicator will flash, and the maximum temperature will be shown in
the ENV TEMP display. If the maximum temperature is checked during flight, you must turn the
receiver back to on to receive actual envelope temperature and for the temperature alarms to
work. Maximum envelope temperature is not saved when the main power is turned off.
7.2.2

Pairing to a 3040

In order for the 3040 to receive data from a TT34 it must first be paired. This is accomplished by
setting the TT34 ID code (serial number) into the 3040.

If you do not know the TT34 code, or if the setting is inadvertently lost in flight, enter Set-mode
as above and set the ID code to 0 by simultaneously pressing the !" keys (0 is the automatic
scan mode). Short-press the ENV TEMP key; the 3040 will return to Run-mode and will self-
install the first received TT34. This method should only be employed when there are no other
balloons using a TT34 in close proximity, to avoid self-installing another pilot's TT34 code. For
this reason it is recommended that the s/n of the TT34 be marked somewhere in the balloon
basket. This way it will be available in flight, in the event the code is inadvertently lost.

that if the 3040 is used with a TT34, the REC switch be left
in the ON position. In that case the 3040 will display the
envelope temperature as soon as a valid signal is
detected.
Note: No envelope temperature is displayed and all
temperature alarms are disabled if the REC switch is OFF.
When the REC switch is off, the display cannot be set to
ENV TEMP; only AMB TEMP and CHRONO can be
selected.
With the receiver set to ON, select ENV TEMP with short
presses of the ENV TEMP/AMB TEMP/CHRONO key (the
arrow indicator pointing to ENV TEMP).
Long-press the ENV TEMP key to enter Set-mode; the
TT34 ID code will be flashing. Use the !"keys to adjust
the number to the s/n of the desired TT34. Short presses
of an arrow key will increment the value in the direction of
the arrow pressed, whereas holding down an arrow key will
accelerate the number change in that direction until the
key is released. Press the ENV TEMP key to confirm the
entry and return to Run-mode.
