4. Maintenance
4.1. Sensor Cleaning
The D90 features an Integrated Dust Reduction System that uses 4-frequency ultrasonic vibrations to free image-degrading dust particles from the sensor's optical low-pass filter. Regular use of this function helps maintain image clarity. For stubborn dust, professional cleaning may be required.
4.2. General Cleaning
Use a soft, lint-free cloth to clean the camera body. For the LCD monitor, use a specialized LCD cleaning cloth. Avoid using harsh chemicals or abrasive materials. Keep the lens and sensor free from dust and fingerprints by using appropriate cleaning tools (e.g., a blower brush for dust, lens cleaning solution for smudges).
4.3. Battery Care
To prolong battery life, store the battery in a cool, dry place when not in use. Avoid extreme temperatures. Fully charge the battery before extended shooting sessions. If the camera will not be used for a long period, remove the battery.
