Canon EOS Rebel T3 Mode D'emploi page 11

LCD Monitor
Although the LCD monitor is manufactured with very high precision
technology with over 99.99% effective pixels, there might be a few dead
pixels among the remaining 0.01% or less pixels. Dead pixels displaying
only black or red, etc., 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.
In low or high temperatures, the LCD monitor display may seem slow or it
might look black. It will return to normal at room temperature.
Cards
To protect the card and its recorded data, note the following:
Do not drop, bend, or wet the card. Do not subject it to excessive force,
physical shock, or vibration.
Do not touch the card's electronic contacts with your fingers or anything
metallic.
Do not store or use the card near anything having a strong magnetic field
such as a TV set, speakers, or magnet. Also avoid places prone to having
static electricity.
Do not leave the card in direct sunlight or near a heat source.
Store the card in a case.
Do not store the card in hot, dusty, or humid locations.
Lens
After detaching the lens from the camera, attach the lens
caps or put down the lens with the rear end up to avoid
scratching the lens surface and electrical contacts.
Cautions During Prolonged Use
If you use continuous shooting, Live View shooting, or
movie shooting for a prolonged period, the camera may
become hot. Although this is not a malfunction, holding the
hot camera for a long period can cause slight skin burns.
About smudges adhering to the front of the sensor
Besides dust entering the camera from outside, in rare cases lubricant from the
camera's internal parts may adhere to the front of the sensor. If visible spots
remain on the image, having the sensor cleaned by a Canon Service Center is
recommended.
