ALTIMETERS lb-solo-II Altimeter
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 at: www. L-and-B.dk

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.
