Canon EOS REBEL T7i Manual De Instrucciones Básicas página 21

If condensation forms on the camera, do not use the camera. This is to avoid

damaging the camera. If there is condensation, remove the lens, card and
battery from the camera, and wait until condensation has evaporated before
using the camera.
If the camera will not be used for an extended period, remove the battery

and store the camera in a cool, dry, well-ventilated location. Even while the
camera is in storage, press the shutter button a few times once in a while to
check that the camera is still working.
Avoid storing the camera where there are chemicals that result in rust and

corrosion such as in a chemical lab.
If the camera has not been used for an extended period, test all its functions

before using it. If you have not used the camera for some time or if there is
an important shoot such as a foreign trip coming up, have the camera
checked by your nearest Canon Service Center or check the camera
yourself and make sure it is working properly.
If you repeat continuous shooting or perform Live View shooting or movie

shooting for a prolonged period, the camera may become hot. This is not a
malfunction.
If there is a bright light source inside or outside the image area, ghosting

may occur.
LCD Monitor
Although the LCD monitor is manufactured with very high precision

technology with over 99.99% effective pixels, 0.01% or fewer of the pixels
may be dead, and there may also be spots of black, red, or other colors.
Dead pixels are not a malfunction. They do not affect the images recorded.
If the LCD monitor is left on for a prolonged period, screen burn-in may occur

where you see remnants of what was displayed. However, this is only
temporary and will disappear when the camera is left unused for a few days.
The LCD monitor display may seem slightly slow in low temperatures, or

look black in high temperatures. It will return to normal at room temperature.
