Maintenance

Although TPS does not need periodical maintenance, a functional check with every facility maintenance check is
strongly recommended.

Confirm sensor is fastened securely

Ensure the front window / lenses of TPS are clean and without scratches
8.2.

Cleaning

Clean the front surface from dust or dirt with a soft towel. To clean the surface with a towel, it must be either dry
or slightly moist, but should not be wet.
