Larsen & Brusgaard PROTRACK II User manual

#2.1

Every technical device can fail. So everything
imaginable can happen with the PROTRACK II,
including, but not limited to: displaying a status
which is not true, failing to function, or functioning
at a wrong moment or at a wrong occasion. If you
or your friends or family are not willing to accept
these uncertainties and risks, then please don’t use
PROTRACK II.
PROTRACK II Manual

WARNING!
FAILURE TO FOLLOW ALL WARNINGS, INSTRUCTIONS, AND REQUIRED PROCEDURES MAY
RESULT IN SERIOUS INJURY AND DEATH.
Always ensure your PROTRACK II is adjusted to the selected DZ elevation prior to
jumping to account for any changes in barometric pressure.
Audible altimeters may give erroneous warnings if you are tumbling or the altimeter
is in a burble (wake), such as when sit flying.
If you are in doubt about how this limitation affects your skydiving, consult a
licensed instructor.
DO NOT use this equipment unless you are currently participating in, or have
successfully passed, an approved skydiving course.
The PROTRACK II is intended to be a backup device and must not be relied upon as
your primary means of maintaining altitude awareness.
Do not put the PROTRACK II directly next to your ear when testing the freefall alarm
PROTRACK II is a trademark of LB ALTIMETERS, Denmark.

Therefore, we reserve the right to make changes and improvements to any of the
products described in this guide without prior notice.

sounds on the ground, as the PROTRACK II 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 PROTRACK II on the ground.
If the PROTRACK II is not mounted correctly, you may not hear the alarm sounds.
Make sure the PROTRACK II is mounted correctly before you jump.
The PROTRACK II must be active (powered ON) prior to entering the airplane.
Do not perform ACCESS less than 1 minute prior to exit.
Use the PROTRACK II at your own risk.

After power up, the PROTRACK II enters Ground Mode.
In Ground Mode, the screen display will switch OFF after 60 seconds to save battery
power. However, the unit is still ready to jump.
The PROTRACK II uses very little power and does not need to be switched OFF.
However, we recommend that you switch OFF the PROTRACK II when traveling on
commercial flights, when driving in mountainous areas and when the jump season is
over. To power OFF the PROTRACK II, see “Power OFF” section.
5 - Power ON
The PROTRACK II 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 PROTRACK II runs a self-test and sounds two beeps as it flashes the screen two
times. It then displays a “Device Info” screen.

7 - Flight Mode
Shortly after take-off the Flight Mode window turns ON, indicating that the unit has
switched to Flight Mode. This window will show current altitude, date, and time.
At the lowest “Climb to Altitude” warning the PROTRACK II sounds a sequence of
beeps. See chapter 12 ”Climb to Altitude Warnings” for further explanation.
6 - Ground Mode
After Power ON and shortly after landing from a jump the PROTRACK II enters
Ground Mode.
In Ground Mode the PROTRACK II continually records the ambient air pressure and
temperature and within 30 minutes calibrates itself to the local elevation.
In Ground Mode the screen display will switch OFF after 60 seconds to save battery
power. However, the unit is still ready to jump.
When in Ground Mode, press any key to enter the main window.

- High Speed Warnings (HI-xx)
- Low Speed Warnings (LO-xx)
- Logbook

9 - Performing ACCESS
Note: Do not perform ACCESS less than 1 minute prior to exit.
To avoid any unintentional changes in settings, all settings are “locked” behind an
ACCESS procedure.
ACCESS procedure is required to change any settings in the PROTRACK II.
1. Press and quickly release – 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, immediately release
By repeatedly pressing the PROTRACK II scrolls through the menu functions in the
selected window.

30 31
To leave a menu function, wait until the display times out, or press and hold for
5 sec.
NOTE: The PROTRACK II goes out of ACCESS and back to the Main
Display if no button has been pressed within 30 sec.
All functions (except Power ON) can be performed ONLY when the PROTRACK II is
in ACCESS mode.
10 - Altitude Offset
MM-DD
HH-MM
Explanation:
If the Landing Zone (LZ) elevation is different from that of the aircraft takeoff, use the
altitude offset capability to set the difference prior to entering the airplane, or set the
altitude offset to zero when climbing through the LZ elevation.

32 33
Perform ACCESS from the flight mode screen:
The altitude (normally 0) next to the FT or MT indicator will begin to flash.

34 35
Press or to set an altitude offset to match the altitude of the aircraft takeoff
relative to the Landing Zone.
Examples:
1) If the aircraft takeoff is 2000 ft. lower than the Landing Zone, the altitude offset must
be set to “-2000 ft.”
If the aircraft takeoff is 1500 ft. higher than the Landing Zone, the altitude offset
must be set to “1500 ft.”
2) If the PROTRACK II is switched OFF during climb to altitude. Switch the PROTRACK II ON
and adjust the altitude to the same altitude as shown on the airplane altimeter (AGL).
3) When doing a B.A.S.E. Jump (> 6 sec. freefall)
At the exit point enter the present altitude above the landing area.
4) When climbing to exit altitude in an airplane with a pressurized cabin activated.
When cabin pressure has been released, program the unit to the present altitude or
to a compensated altitude.
WARNING
Be cautious when operating the Altitude Offset.
If programmed to an altitude different from the present altitude, the pre-selected
warning alarms will sound relative to the new programmed altitude.
NOTE: DO NOT PROGRAM ALTITUDE OFFSET LESS THAN 1 MINUTE PRIOR TO EXIT.
NOTE: When performing manual altitude offset the PROTRACK II enters
Flight Mode and stays in Flight Mode for 14 hours, if no jump is made.
After 14 hours the PROTRACK II recalibrates to the field elevation where it is currently
located and enters Ground Mode. The altitude offset is not retained when the PROTRACK
II is powered OFF.

36 37
11 - Warning Windows (common for all)
The following options are available after performing ACCESS in “Climb to Altitude
(CL)”, “High Speed (HI)” or “Low Speed (LO)” windows.
- Select Warning Memory Bank
- Set or disable warnings
- Enable / Disable Guide Tones (only for Low Speed warnings)
- Set volume
- Set pitch
- Hear selected warnings, volume and pitch
11.1 Warning Memory Bank Description
The PROTRACK II makes it possible to store warning altitudes in four custom ”Warning
Memory Banks”. This is a useful option when performing various types of jumps, e.g.,
Freefly, AFF, Tandem, Camera, etc.
In the Warning Bank area, a number indicates which Warning Memory Bank the
warning altitudes are stored in.
NOTE: The PROTRACK II will sound at the selected altitudes that were displayed
last on the LCD.
