Climb to Altitude Warnings and Altitude
Offset Selector
Description
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), signifi es a 500-foot altitude increment.
Should the battery voltage of the QUATTRO show low capac-
ity, the beep sequence is followed by 5 short beeps. This
indicates that the batteries should be replaced.
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.
When the aircraft begins climbing to altitude, the QUATTRO displays
the current altitude at the top of the display.
Setting
The setting of warning altitudes can be performed either on
the ground or in the airplane during climb to jump altitude.
Setting Climb to Altitude Warnings and Altitude Offset
NOTE: Minimum selectable height is 1000 ft (300 meters)
Note: 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.
Three 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 3rd warning altitude fl ashes
6. Press
or
to change 3rd warning altitude
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 warn-
ing alarms such that the highest warning altitude become
the 1st warning alarm, the next highest warning altitude
becomes the 2nd warning alarm, and the lowest warning
altitude becomes the 3rd warning alarm.
One or Two Warning Alarms
If you wish only one warning alarm or two alarms, preset the
not used alarm(s) to ---
Altitude Offset
Explanation:
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.
Press
again. The altitude (normally 0) next to the FT or
MT indicator will begin to fl ash.
Press
or
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 fi eld 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
function described above.
Battery Status
Full capacity: Symbol shows two black bars inside the bat-
tery icon.
Half capacity: Symbol shows one black bar inside the battery
icon.
Low capacity: Symbol shows no black bars, just an “empty”
battery icon. Batteries should be replaced as soon as pos-
sible.
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 fl ashes. Replace batteries
immediately.
Mounting the QUATTRO
The QUATTRO can be mounted on the outside of the helmet.

shooting and when verifying software version number.
Air Filter
The QUATTRO is water resistant.
The Air Filter is the white circular part mounted on the side
of the unit. If it becomes wet (after a splash in the swoop
pond) then 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 which can be
purchased separately.
