Appendix C: Troubleshooting
• Check battery status on both units when there is a problem. Low battery power may cause data errors.
Error: Radar Time Out or Connection Abandoned error box appears.
Solution: Exit out of LifeLocator, reenter and try again. If same error appears, repeat the Startup Procedure including
turning the sensor Off then On again.
turning the sensor Off then On again.
Error: Erratic detection of motion or breathing.
Solution: Check around the sensor. Make sure there is no other motion in the vicinity of the sensor. Check sensor and
control unit battery power. If problems persist, the environmental noise due to other communications equipment may be
overwhelming the sensor. These can be visualized in EXPERT mode.

Note: The internal 1GB card can store more than 50 hours of data on the sensor. Since the file system was never intended
to go beyond File 99, it will keep overwriting File 99 once it is reached. It is hard to imagine that one would collect all 99
files ½ hour long, but if the 1GB card is full, the system may hang. You would need to Clear Storage and delete all files to
recover. Periodically clear storage to avoid memory issues.

Error: High radio frequency noise/WiFi environment or nearby waving vegetation causes false positive indicators.
Solution: Enter Maintenance Mode (from Main menu press Maintenance three times then press Yes). On the Maintenance
screen press Sensitivity which will change the System setting to Low. Penetration range will not be affected. System
setting can be changed back to High by pressing Sensitivity again.

Appendix D: System Use
1.
The user should place the sensor face down on the rubble and back away about 30 feet or more (up to 50 feet max).
The wireless control unit collects data for about three minutes and indicates the presence and distance to the victim.
Motion and breathing may be detected as early as twenty seconds. A longer period of time improves the confidence
level of detection. After three minutes, the sensor should be moved to the next point in the search grid.

2.
A single sensor returns only the approximate distance to but not the exact position of the victim, since there is a
“solid viewing angle” that widens and narrows depending on the medium being penetrated.
“solid viewing angle” that widens and narrows depending on the medium being penetrated.
For example, the victim might be six feet away from the sensor but not directly beneath it
In moist sand, the victim could be about 50 degrees away from perpendicular, whereas in dry sand or concrete
rubble, this angle might be wider.
rubble, this angle might be wider.
3.
Since it is impossible to know when disasters will strike, it is important that LifeLocator training be conducted
routinely so that users are skilled at System operation. It is equally important that the System batteries are fully
charged at all times and UVSS recommends a minimum of a
monthly inspection of all System batteries to maintain optimum
performance.

Although a user might get the victim’s position by moving a single sensor around
and triangulating the distances, it is likely to be more important to simply to make
the positive ID and start digging. A proposed search pattern is shown in the
diagram. It uses 12-foot (4m) spacing between search points with staggered lines
to minimize the area not searched close to the surface. Once areas are identified
(clear, suspect, etc), mark the area with paint, flags, etc.
