Do this gently because these are horribly flimsy and really easy to break.
Drop out any batteries that were in there.
Check the battery terminals for corrosion if you just bought the camera.
If they are covered in a white residue, spray on some electrical contact cleaner and carefully scrape away any residue with a sharp implement.

Never use rechargeable batteries–Canon warns against this (which either means that the metering will be wrong or your camera will explode).
Do your part to destroy the environment by dropping in a pair of disposable batteries (“heavy duty” carbon-zinc or alkalines).
Close the battery door; again, be as gentle as you can, to avoid breaking it.

Again, line up the two red dots.
Then, rotate the body of the lens until it clicks into place, just like the bayonet-mount lenses for other cameras which these lenses pretend to be.
A solid, non-blinking P: green means go![1] X Research source The camera is happy and ready to shoot. A slowly-blinking P: If it blinks about twice a second, it’s warning you that your picture might be blurred by camera shake (this happens if the shutter speed is down to 1/30 or slower). Use a tripod or brace yourself against a solid surface. [2] X Research source Or do as Canon’s manual recommends and nuke your subject with direct flash, if you insist on getting boring photographs. If you find yourself down in this range quite a lot, you might want to consider shooting a faster film. A rapidly-blinking P: You’re dead; you’re either trying to operate outside the T50’s metering range or you’re going to need a shutter speed longer than two seconds. The T50 simply cannot operate under extreme low-light conditions.
