Mode Setting Feedback
For an easier mode setting follow-up, a feedback tone is being generated when the switch is activated, e.g. a
double “beep, beep” for the altitude mode. The different feedbacks are outlined above.
5.4
Standby Mode
Selecting the standby mode puts the vario into a quiet mode, which begins after a
single
announcement of
the
actual altitude
and R/C system
voltage
.
The
actual speed
is announced as well if a GPS module is connected.
Additional (single) announcements are being made if the sensor interface either from WSTECH or SM-
Modellbau is connected. Details are described in chapter 8.
After these announcements, the vatro tone and the voice output become silent. Only the voltage check and
and its announcement remain active in the background. The vario transmitter is being switched off and the
vario draws only a very small current.

GPS Operating Options
The GPS module from WSTECH allows the announcement of (ground) speed, glide ratio and the model`s
position. The GPS module can be connected to the vario either with or without the sensor interface.
Airspeed can be measured with the airspeed sensor from SM-Modellbau plus the sensor interface from
WSTECH or SM-Modellbau.
6.1
Speed Mode
The speed announcement can selected either in two different
continous
modes or as a
single
announcement
upon selecting the standby mode.
Setup 4 offers a recurring announcement every 3 seconds (Setup 4 on “1”) or a maximum speed
announcement after an acceleration phase (Setup 4 on “2”).
Upon activation of the speed mode in either above operating modes, the maximum speed during the
previous speed mode activation is being announced.
During the “maximum speed after an acceleration phase” mode, speed announcements are being repeated
every 3 seconds, except when the speed is still increasing. I.e. during a dive with its increasing speed, no
announcements are being made and only a one-second-beep signals that a measurement is being
performed. As soon as there is no more speed increase detected after three measurement cycles, the
previously measured maximum value is being announced (exemple: “two-hundred-sixteen-k-m-h”) and
afterwards the announcements return to the actual speed.
If a definite speed increase cannot be detected, there continues an actual speed announcement approx.
every 5 seconds.
After these announcements, the vario tone and the voice output become silent. Only the voltage check and
and its announcement remain active in the background. The vario transmitter is being switched off and the
vario draws only a very small current.
The speed mode is activated by selecting the integral mode first and then switching directly into the standby
mode. The last previously measured speed value is then announced before the actual readings are
continued.
Please note
that there are two versions of GPS modules which have the following characteristics:
GPS module with a
green LED
: The LED blinks as long as no satellite signal is received and there is no
voice output. The LED signals reception with solid green and voice output is generated along the selected
setting.
GPS module with a
red LED
: The GPS module becomes active as soon as the solid red changes to a
blinking red.
If the pitot tube sensor from SM-Modellbau is used (together with the WSTECH or the SM-Modellbau sensor
interface), all above functions can be used without a GPS module, however, the readings will be “airspeed”
instead of “ground speed”.
6.2
Position Announcement
This feature is only possible with a WSTECH GPS module. An
automatic
position announcement serves as
a support in case of a crash or a landing in a remote area. This announcement is generated in all modes as
soon as the model remains in a +/- 8 m/24 ft altitude window for a period of 2 minutes and more. This will
almost never happen during the flight and the pilot will not be distracted because of unnecessary
announcements. The automatic announcement after an emergency allows the retrieval of the model by using
