WARNING!
The QUATTRO is intended to be a backup device and must
not be relied upon as your primary means of maintaining
altitude awareness. Use the QUATTRO at your own risk.
Do not put the QUATTRO directly next to your ear when test-
ing the alarm sounds on the ground, as the QUATTRO alarm
volume is very loud. It may cause pain or damage to the ear.
Due to outside wind noise in freefall, the alarm sounds will
not be perceived to be as loud as when testing the QUATTRO
on the ground.
If the QUATTRO is not mounted correctly, you may not hear
the alarm sounds in freefall. Make sure the QUATTRO is
mounted correctly before you jump.
The QUATTRO must be active (powered on) prior to entering
the airplane.
INTRODUCTION
Congratulations on purchasing your new QUATTRO!
The QUATTRO audible altimeter is the latest in micro technol-
ogy and features the most advanced programming for
accurately measuring freefall & canopy descent rates. The
QUATTRO allows the skydiver four sets of warning altitudes
for high speed and three for low speed fl ight. This provides
added interactivity in confi guring frequently used warning
alarms. The QUATTRO can also be set up to three climb warn-
ing alarms for the ultimate in precision altitude awareness.
NEW!! The QUATTRO raises the bar yet again to provide sky-
divers with the most accurate and useful functions available
in an audible altimeter:
- Four high-speed warnings:
Allows settings up to 19990 Feet and can be used for
Bigway formations, wingsuit fl ight setup and other precision
skydives where four high-speed warnings are needed and
desired.
- Track Guide:
0.5 second pulsating tones between the 1st and 2nd warn-
ings help keep track of altitude separation of tracking groups
or waves.
- Three canopy descent and low speed warnings:
The Canopy Descent Alerts are essentially low speed alerts
and can also be used by wingsuit fl yers to keep track of alti-
tude in preparation for separation and canopy deployment.
The QUATTRO is fully automatic and can be manually turned
off or on as well. The QUATTRO continually reads ambient
air pressure for real-time accuracy and attention to ground
level.
The QUATTRO’s small and ergonomic design provides the
user with comfort & less bulk when used inside a soft or
hard-shell helmet. Rigging materials are included for those
wishing to mount the audible on the outside of a helmet.
The QUATTRO is specifi cally designed for advanced skydiving
disciplines: Bigways, Formation Skydiving, Freefl ying, Wing-
suit Flying, Student, Tandem, AFF, and also canopy related
activities such as accuracy and CRW.
QUATTRO sets the standard as being the most advanced audi-
ble altimeter available with more features, greater accuracy
and the ability to fi nely tune your altitude awareness.

Three Warning Alarms
You can choose to only have three warning alarms. The
procedure is the same as above, but choose same altitude for
the 1st and 2nd warning alarms (the QUATTRO then sounds
only the 2nd, 3rd and 4th warning alarms).
NOTE: Track Guide is then disabled.
Two Warning Alarms
You can choose to only have two warning alarms. The proce-
dure is the same as above, but choose same altitude for the
1st, 2nd and 3rd warning alarms (the QUATTRO then sounds
only the 3rd and 4th warning alarms).
One Warning Alarm
If you want only one warning alarm, choose same altitude
for all four warning alarms using the above procedure. (The
unit sounds only the 4th warning alarm).
Track Guide
Press
again.
Explanation:
When Track Guide is activated, a series of 0.5 second beeps
sound between the 1st and 2nd high speed warning.
To enable Track Guide
Press repeatedly until Track Guide fl ashes. Press
or
until the Track Guide icon is ON.
To disable Track Guide
Press repeatedly until Track Guide fl ashes. Press
or
until the Track Guide icon is OFF.
NOTE: When Track Guide is enabled, the Track Guide icon will show
in the warning bank area of all warning bank displays and in the
Main Window.
Sound Volume
Press
again.
Four output values will begin to fl ash.
Press
or
to select output volume for all four high-
speed warnings.
”1” is very low volume (112 dB), ”10” is very high volume
(117 dB)
The QUATTRO is factory preset to ”7”.
NOTE: In case of low battery battery capacity the volume will
automatically switch to ”1” and it cannot be changed until the
batteries have been replaced.
Sound Volume Track Guide
Press
again.
One output value will begin to fl ash.
Press
or
to select output volume for Track Guide.
”1” is very low volume (112 dB),”10” is very high volume
(117 dB)
The QUATTRO is factory preset to”3”.
NOTE: In case of low battery capacity the volume will automatically
switch to ”1” and it cannot be changed until the batteries have
been replaced.
Sound Pitch
Press
again.
The musical note icon and pitch bar graph will begin to
fl ash.
Press
or
to change the pitch up or down. The pitch
bar graph will display the number of bars corresponding to
the selected pitch and the selected pitch will sound.
Note: When selecting a pitch on either side of the center
vertical bar (3,800 Hz), the output volume decreases about
5 dB because the speaker is no longer at its optimum
resonance frequency.
Test Warning Sounds
Press
again.
The ear icon will begin to fl ash.
Press
or
.
This causes the QUATTRO to sound the preset alarm sequence
at the selected pitch.
INSTRUCTIONS
Power ON
The QUATTRO has been powered off prior to shipping from
our factory. To turn the power ON, press and hold any key
until the unit beeps, then release the key. The QUATTRO runs
a self-test and sounds three beeps as it fl ashes the screen
three times. It then displays a screen confi guration referred
to henceforth as the “Main Window”.
This represents the starting point for all further actions with
respect to QUATTRO actions and subsequent displays.
NOTE: To save battery power, the screen display will switch OFF after
14 hours. However, the unit is still ready to jump.
Performing ACCESS
Performing ACCESS can be done in the:
1) Climb to Altitude Warnings and Altitude Offset Window
2) High Speed Warnings and Setup Selector Window
3) Canopy Descent and Low Speed Warnings Window
1. Press
and release quickly – the padlock icon turns off
(disappears)
2. When the padlock icon reappears, immediately press
and keep it pressed – the padlock icon will disappear
again
3. When the padlock icon appears again,
release immediately
NOTE:: The QUATTRO goes out of ACCESS and back to the Main
Window if no button has been pressed within 5 sec. ALL functions
(except Power ON) can be performed ONLY when the QUATTRO is in
ACCESS mode.
Menu Function Sequence
By repeatedly pressing
the QUATTRO scrolls through the
menu functions in the selected window:
To leave a menu function, wait until the display times out,
or,
press and hold
for 5 sec.,
or,
press repeatedly until the padlock icon fl ashes, then press
or
to exit.
High Speed Warnings and Setup Selector
Perform ACCESS in the High Speed Warnings and Setup
Selector Window.
Warning Bank Menu Functions
The QUATTRO has four freefall warning banks.
When the warning bank icon is fl ashing, press
or
to
select warning bank 1 to 4.
Setting the Warning Altitudes
The setting of altitudes in each warning bank can be per-
formed either on the ground or in the airplane during climb
to jump altitude.
Four Warning Alarms
1. Press
until 1st warning altitude fl ashes
2. Press
or
to change 1st warning altitude
3. Press
again and the 2nd warning altitude fl ashes
4. Press
or
to change 2nd warning altitude
5. Press
again and the 3rd warning altitude fl ashes
6. Press
or
to change 3rd warning altitude
7. Press
again and the 4th warning altitude fl ashes
8. Press
or
to change 4th warning altitude
Sequence of Warning Alarm Altitudes
You may note that when setting the warning altitudes, it is
possible to set the 1st warning alarm altitude lower than the
second or even the 4th warning altitudes. The 2nd warning
altitude could be set to a higher value than the 1st warning
altitude or a lower value than the 3rd warning altitude, and
so on. This is not a problem – when the QUATTRO exits
ACCESS mode, it will automatically sort and store the warn-
ing alarms such that the highest warning altitude becomes
the 1st warning alarm, the next highest warning altitude
becomes the 2nd warning alarm, and the lowest warning
altitude becomes the 4rd warning alarm.
