WARRANTY
The following conditions apply to the QUATTRO warranty: Within 12 months after
delivery, damage or defects in the unit that is proven to be caused by faulty
manufacture will be repaired by LARSEN & BRUSGAARD at no cost to the end-user.
To make a claim under this warranty, send the unit to an authorized dealer, or
directly to LARSEN & BRUSGAARD, together with the dated purchase invoice or
receipt. The
warranty becomes void if the damage is caused by external circumstances, or if
the unit has been serviced or repaired by third parties unauthorized by our
national agents or
LARSEN & BRUSGAARD.
All further claims, especially for defects after skydiving accidents, are
excluded. LARSEN & BRUSGAARD has no obligation to honor any extension of
warranty granted by any national agent.
WAIVER OF LIABILITY
The buyer and user of the QUATTRO indemnify the manufacturer and vendor from
any liability for damage incurred before, during, and after skydiving with the
instrument.
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.
When testing the QUATTRO on the ground the alarms sounds may be perceived
louder than in freefall, due to the lack of outside wind noise and pressure
changes.
Do not put the QUATTRO directly next to the ear while testing the alarm sounds
on the ground, as the QUATTRO alarm volume is very loud. It may cause pain or
damage
to the ear.
The QUATTRO must be mounted correctly, to ensure the alarms are audible during
freefall. Always ensure the
QUATTRO is mounted correctly prior to jumping. 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 microtechnology and features
the most advanced programming for accurately measuring freefall & canopy
descent rates.
The QUATTRO allows the skydiver up to 4 sets of warning altitudes for high
speed, and 3 for low-speed flight. This provides added interactivity in
configuring frequently used
warning alarms. The QUATTRO can also be set up to three climb warning alarms
for the ultimate precision altitude awareness.
The QUATTRO raises the bar yet again to provide skydivers with the most
accurate and useful functions available in an audible altimeter:
• 4 High-Speed warnings:
Allows settings up to 19990 feet and can be used for large formations,
wingsuit flight setup, and other precision skydives where multiple high-speed
warnings are needed
and desired.
• Track Guide:
0.5-second pulsating tones between the 1st and 2nd warnings help keep track of
altitude separation, in tracking groups or waves.
• 3 Canopy Descent / Low-Speed warnings:
The Canopy Descent warnings are essentially low-speed warnings, and can also
be used by wingsuit flyers to keep track of altitude in preparation for
separation and canopy deployment.
The QUATTRO is fully automatic and can be manually turned ON or OFF. 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 and
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 specifically designed for advanced skydiving disciplines: Large
Formations, Relative Work, Free Flying, Wingsuit Flying, Student, Tandem, AFF,
and also canopy-related activities such as accuracy and CRW.
QUATTRO sets the standard as being the most advanced audible altimeter
available with more features, greater accuracy and the ability to finely tune
your altitude awareness.

Climb to Altitude Warnings and Altitude Offset Selector
The altitude during climb at which the beep is heard may be changed or up to
three different altitudes during climb may be selected for beep sounds.
At the lowest preset altitude (factory preset to 1,000 feet), the QUATTRO
sounds a sequence of beeps. These beeps have two functions:
1. The beeps indicate that the QUATTRO has calibrated itself to the local
ground elevation and is ready to jump.
2. The number of beeps indicates the altitude at which the highest warning
alarm is set; for example: If set to 4,500 feet, the signal will sound: beep-
beep-beep-beep(pause)beep.
The number of rapid-sequence of beeps indicates the highest warning altitude
in thousands of feet.
The beep after a pause (if any), signifies a 500-foot altitude increment.
Should the battery voltage of the QUATTRO show low capacity, the beep sequence
is followed by 5 short beeps. This indicates that the batteries should be
replaced.
When the aircraft begins climbing to altitude, the QUATTRO displays the
current altitude at the top of the display.
NOTE: At the same time the output volume setting is automatically changed
to low volume “1” and it cannot be changed until the batteries have been
replaced.
Setting Climb to Altitude Warnings and Altitude Offset The setting of warning
altitudes can be performed either on the ground or in the airplane during the
climb to jump altitude.
Note : Minimum selectable height is 1000 ft (300 meters).
Default values ‘1000 ft’., ‘— ft.’, and ‘— ft.’ have been factory preset for
Climb to Altitude Warnings.
In the Main Window mode, press to access the Climb to Altitude Warnings and
Altitude Offset Selector. Perform ACCESS in this window.
3 Warning Alarms
- Press until 1st warning altitude flashes
- Press to change 1st warning altitude
- Press again and the 2nd warning altitude flashes
- Press to change 2nd warning altitude
- Press again and 3rd warning altitude flashes
- Press to change 3rd warning altitude
The sequence of Climb 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 2nd or even the 3rd 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 warning 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 3rd warning alarm.
1 or 2 Warning Alarms
If you wish only 1 warning alarm or 2 alarms, preset the alarm(s) not used to
‘— ft.‘
Altitude Offset
If the DZ elevation differs from that of the airport of takeoff, use the
altitude offset capability to set the DZ elevation prior to entering the
airplane or set the altitude offset to
zero when climbing through the DZ elevation (positive altitude for higher DZ
elevation, negative altitude for lower DZ elevation).
Press again. The altitude (normally 0) next to the FT or
MT indicator will begin to flash.
Press to set an altitude offset to match the altitude of the landing DZ
relative to the takeoff airport.
NOTE : When performing manual altitude offset the QUATTRO enters Jump
Mode and retains the altitude offset for 14 hours if no jump is made.
After 14 hours the QUATTRO recalibrates to the field elevation where it is
currently located and once again displays 0.
The altitude offset is not retained when the QUATTRO is powered OFF.
OPERATIONAL CONSIDERATIONS
Prior to Jumping
The QUATTRO continually adjusts to the local elevation and displays 0 FT (MT)
at the top of the display. If the top of the display does not show “0” (or
your selected altitude
offset) prior to jumping, the unit has not adjusted itself to the local
elevation and it must be manually zeroed. See the section, “Altitude Offset
Function” under Menu functions
above. Even when the display turns OFF, the unit is still ready for jumping.
Setting an Altitude Offset
If the drop zone (DZ) elevation is different from that of the takeoff airport,
you may compensate for this difference by setting an Altitude Offset – see the
Altitude Offset menu
the function described above.
Battery Status
Full capacity: Symbol shows two black bars inside the battery icon.
Half capacity: Symbol shows one black bar inside the battery icon.
Low capacity: The symbol shows no black bars, just an “empty” battery icon.
Batteries should be replaced as soon as possible.
As a reminder, 5 short beeps sound when climbing through the lowest preset
climb altitude. At the same time, the output volume setting is automatically
changed to low volume “1”.
Empty batteries: The battery icon flashes. Replace batteries immediately.
Mounting the QUATTRO
The QUATTRO can be mounted on the outside of a helmet.
Loop the wax cord through the four mounting holes and fasten with knots to the
helmet.
NOTE : Make sure that there is no material between the QUATTRO
loudspeaker hole and your ear.
Resetting the QUATTRO
Press a paperclip into the tiny hole on the rear side of the unit and release.
The unit restarts.
NOTE: Reset the unit after battery replacement, when troubleshooting and when
verifying software version number.
Air Filter
The QUATTRO is water-resistant against minor splashes of water.
The Air Filter is the white circular part mounted on the side of the unit. If
it becomes wet, let the QUATTRO dry in a warm place for 48 hours.
NOTE: The Air Filter must be replaced if jumping is resumed quickly or if
the QUATTRO has been submerged into water. Air Filter removal tooling kit is
an accessory
that can be purchased separately. QUATTRO Firmware Version Perform reset. The
version number is displayed at the upper part of the screen (altitude area).
The numbers
displayed in the middle of the screen is a factory reference number.

Customer settings are kept in non-volatile memory when removing batteries.
However, the built-in clock may again be set to the correct time.
Trouble-shooting
When the QUATTRO detects a fault, an error (“ERR”) sign and troubleshooting
numbers 2 to 4 are displayed in the upper part of the screen. At the same time
the unit beeps
every minute.
The “ERR” troubleshooting codes are as follows:
ERR 2, ERR 3, ERR 4 = unit is defective. Remedy: perform a reset
If the unit does not function correctly even after replacing
