The Military ALTITRACK is water resistant down to 5 ft for 24 hours.
After jumping into (salt) water the Air Filter may be contaminated with particles (salt and dirt) and
must be rinsed in fresh water or replaced.
21 - Replacing the Air Filter
General: After jumping into (salt) water, the small holes in the Air Filter may have become
contaminated with particles (salt and dirt) which could prevent the sensors inside the instrument
from reading the air pressure correctly on the next jump.
If no particles can be seen after rinsing the instrument in fresh water then replacement of the Air
Filter should normally not be necessary and the unit can be put aside to dry. However, for safety
reasons, LARSEN & BRUSGAARD recommends that the Air Filter is replaced after each water
jump.
After rinsing the Military ALTITRACK thorougly in fresh water, replace the battery cover which has
the Air Filter integrated.
Note: Wrist Mount assembly must be removed before rinsing
