Instruction Manual
WARNING!
The SOLO is intended to be a backup device and must not be relied upon as your
primary means of maintaining altitude awareness.Use the SOLO at your own risk.
When testing the SOLO II 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 SOLO II directly next to the ear while testing the alarm sounds
on the ground, as the SOLO II alarm volume is very loud. It may cause pain or
damage to the
ear. The SOLO II must be mounted correctly, to ensure the alarms are audible
during freefall. Always ensure the SOLO
II is mounted correctly prior to jumping.
The SOLO II must be active (powered on) prior to entering the airplane.
INTRODUCTION
Congratulations on purchasing your new SOLO II! The SOLO II design is based
upon the latest fi ndings in microcomputer technology and freefall parameters.
The SOLO II is fully automatic. It continually records the ambient air
pressure and temperature and adjusts the electronic circuitry to the local
elevation. The SOLO II’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 SOLO II can be mounted on the outside of any type of helmet
by means of the enclosed ties. The SOLO II is specifi cally designed for
advanced skydiving disciplines: Relative Work, Free Flying, Student, Tandem,
and AFF Please read ALL of the instructions prior to actual skydiving use. It
is a very good idea to practice ACCESS’ing the SOLO II and setting the warning
values on the ground prior to your fi rst jump with the SOLO II. For further
information or to ask questions about OLO II or any other L&B altitude
awareness instrument, please visit our website and our Product Support Forum

INSTRUCTIONS
Power ON
The SOLO 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
button. SOLO II runs a self-test and sounds three beeps.
Perform ACCESS
General note: The SOLO II goes out of ACCESS if no button has been pressed
within 5 sec. ALL functions (except Power ON) can be performed ONLY when the
SOLO II is in ACCESS mode.
- Press and release quickly
- When the ACCESS indicator light illuminates, immediately press **** and keep it pressed
- When the ACCESS indicator illuminates again, release it immediately
The SOLO II now displays three preset warning altitude lights.
Setting the Warning Altitudes
The SOLO II factory altitude warning settings are:
1st warning: 4,500 ft.
2nd warning: 3,000 ft.
3rd warning: 1,500 ft.
The setting of warning altitudes can be performed either on the ground or in
the airplane during the climb to jump altitude.
3 warning alarms
- Press
- Press to change the 1st warning altitude
- Press
- Press to change the 2nd warning altitude
- Press
- Press to change the 3rd warning altitude
The sequence of warning alarm lights
Please 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
altitude indicator. The 2nd warning altitude indicator could be set to a
higher value than the 1st warning alarm indicator, or a lower value than the
3rd warning altitude indicator, and so on.
This is not a problem; when the SOLO II exits ACCESS mode, it will
automatically sort and store the warning 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.
2 warning alarms
It is possible to only have 2 warning alarms. The procedure is the same as
above, but choose the same altitude for the 1st, 2nd, and 3rd warning alarms
(the SOLO II then sounds only the 2nd and 3rd warning alarms).
1 warning alarm
It is possible to only have 1 warning alarm. The procedure is the same as
above, but choose the same altitude for all
3 warning alarms (the SOLO II then sounds only the 3rd warning alarm).
Testing the alarm sounds Press and hold
Power OFF
The SOLO II can be manually powered OFF to further extend the battery lifetime
when not in use. The preset warning altitudes are stored in non-volatile
memory when the SOLO II is powered OFF. When powered OFF, the SOLO II cannot
be used for jumping.
Press repeatedly until the OFF indicator light illuminates.
Press and hold until the altitude warning, light display starts to count down
(from 65, 60, 55, etc.), then release.
1,000 Feet Test
At 1,000 feet +/-100 feet, the SOLO II sounds a sequence of beeps. These beeps
have two functions:
1. The beeps indicate that SOLO II 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 5,500 feet, the signal will sound: beep-
beep-beep-beep- eep(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 SOLO II be below, the 1,000-foot test
sequence is followed by 5 short beeps.
This indicates that the batteries should be replaced.
Prior to Jumping
The SOLO II normally continuously adjusts itself to the local elevation.
However, if the “READY” indicator light fl ashes, the unit has not adjusted
itself to the local elevation and it must be powered OFF and ON prior to
jumping. Setting a Drop Zone (DZ) Offset If the DZ elevation is higher or
lower than that of the takeoff airport, take this into account when setting
your alarm altitudes; don’t forget to reset the warning altitudes when you
return to your normal DZ environment.
Low Battery
When the ‘Low Bat’ indicator illuminates, replace the batteries. If the
battery voltage is low, the SOLO II sounds 5 short beeps when climbing through
1,000 feet.
Battery replacement
Carefully remove the screw from the battery cover and remove the batteries.
Install new batteries using the correct polarity.
Use only
Renata CR-2325.
Note: Reset the SOLO II after replacing batteries.
Reset
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 and when
troubleshooting.
Air Filter
The SOLO II 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 SOLO II dry in a warm place for 48 hours.
NOTE: The Air Filter must be replaced if jumping is resumed quickly or if
the SOLO II has been submerged into water. Air Filter removal tooling kit is
an accessory which
can be purchased separately.
Mounting the SOLO II
The SOLO II 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 SOLO II loudspeaker hole
and your ear.
Troubleshooting
When the SOLO II detects an internal fault, the warning altitude “65” LED fl
ashes 2 to 4 times. At the same time the unit beeps every minute.
The “65” LED fl ashing codes are as follows:
2, 3 or 4 fl ashes: Unit is not functioning properly Remedy: Perform a reset
If the unit does not function correctly, even after replacing the batteries
and pressing reset, perform the following:
Press and hold while resetting. The SOLO II resets to factory altitude warning
settings.
If the unit is still faulty, please contact your local dealer or LARSEN &
BRUSGAARD.
