Descent Tone; Wind Speed; Time Functions - Flytec 3040 Operation Manual

Descent Tone

The descent tone is a steady beeping, where the pitch of the beep decreases as the rate of
descent increases. Using this tone the pilot can monitor the descent rate without looking at the
instrument. The descent tone can be set so that there is no tone unless the decent rate exceeds
a set threshold. The volume of the tone can be easily set or turned off in flight. Each time the
3040 is turned on the descent tone setting will the same as the last use.

Wind speed

The hand-held wind speed sensor is available as an accessory. The sensor plug
is located on the left side of the instrument. When the sensor is plugged in, the
digital vario display will automatically switch to the speed display and the
indicator arrow will point to SPEED. The wind speed sensor is very accurate and
will measure speeds between 1 and 74 mph. It is ideal for measuring the wind at
the take-off site.

Time functions

The 3040 has two time functions: a 24-hour real-time clock and a stopwatch. The real-time clock
is maintained as long as there is at least one 9V battery installed. When replacing batteries, if
they are done one-at-a-time, the time setting will not be lost in the process. The stopwatch
functions only while the instrument is on; any time value on the display will be lost when the
instrument is switched off.

Short-press the Sink Alarm key to toggle trhough the descent
tone options (off, volume I and volume II). A sample beep will
be given and the descent tone threshold will be shown in the
dial display when volume I and II are selected.
Long-press the Sink Alarm key to bring the instrument into
Set-mode. The descent tone threshold point is indicated in the
dial display with a blinking segment. Use the !"keys to
adjust the threshold between 40 ft/min and 2,000 ft/min. The
threshold in the example is 480 ft/min. Note: When adjusting
the threshold between 1000 and 2000 ft/min, all of the
segments will be flashing between the zero line and the
desired setting as read on the 10-20 scale.
Short-press the Sink Alarm key to accept the
adjusted value and return to Run-mode.
