4.3.a External Cleaning
Clean the exterior of the DBAL-I
2
by flushing with water and wiping with a clean,
soft cloth. Cleaning should be done whenever the DBAL-I
2
becomes dirty or
after exposure to salt water.
4.3.b Exit Port Lens Cleaning
To clean the POINT and ILLUM Exit Port Lenses, wipe clean using a soft cloth or
disposable applicator dampened with water.
4.3.c Battery Compartment
Before each use, inspect the battery and battery compartment for dirt, dust, or
corrosion. If dirty, clean using a soft cloth or disposable applicator.
4.3.d Battery Cap
Prior to water operations or immersion, inspect the O-ring seals in the battery
cap to make sure they are free of sand or dirt particles. If the O-ring becomes
cut, nicked or dried out, it should be replaced. If the battery cap is bent or
scratched in the O-ring seating area, it should be replaced.
4.3.e IR ILLUM
Prior to water operations or immersion, make sure that the IR ILLUM Focusing
Knob has been tightened in a CCW direction so that it is seated on the housing.
This will fully compress the internal O-rings to prevent the possibility of water
infiltrating the housing.
