Dirt, dust and salt air can reduce the thermal sensitivity of the system.
After each mission, rinse sensor lens with low-pressure water to remove
dust and dirt.
The windows should be cleaned with a cotton cloth or lens tissue
dampened with isopropyl alcohol. Light pressure is sufficient to remove
oils, grease, or water spots, etc.
remove larger particles before cleaning.
Fingerprints on the optics windows are especially harmful.

System Wash-Down

The following procedure is optional as missions or SOP
dictate.
Do not use high-pressure water or air (over 2 PSI) to clean
the SGA. High-pressure water or air could cause damage to
the ferrofluidic seals located in the azimuth and elevation
axes of rotation. Use a low-pressure fresh water stream not
less than 0.5" diameter or other low pressure cleaning
method.
Based on standard operating procedures (SOP), the SGA should be
washed off with low-pressure fresh water after each mission. These
components may be exposed to considerable amounts of dirt and
potential corrosive particles that need to be removed. The SeaFLIR II
Imaging System can be operating or shutdown during this procedure
without damage.
4.2.3

Troubleshooting

Fault isolation flowcharts are provided to assist the operator in
maintaining the SeaFLIR II Imaging System in case of a Lowest
Replaceable Unit (LRU) failure. The flow charts cover three different
scenarios, Power faults (Figure 4-1), SGA faults (Figure 4-2) and
Video/Graphic faults (Figures 4-3 and 4-4). Each of the charts shows
probable scenarios and corresponding corrective actions for the fault
types down to the LRU and/or cable assembly.
