CANON IXUS 561
Lens sometimes does not extend and error message 'lens error restart camera' appears when camera is turned on. This does not work without several tries and much button pressing. Problem is not caused by finger(s) in front of lens barrel.

Think your problem is that you are looking in the wrong spot. Don't know why your manual is telling you to look there (are you sure your manual is for the A560)?
Your CR1220 date/time battery is located in the regular battery compartment. Look right beside your AA batteries. You'll see a little flap labeled "CR1220". Slide this open with your fingernail, and take the little coin battery down to your local drugstore to buy a replacement.

Here is the suggestion:

The battery compartment cover and the design of the metal electrical contacts is flawed. These acontacts re made of springy metal, but there isn't enough force to press the metal securely against the battery. The end of each contact has a metal tab that prevents it from being bent further out to increase the tension. These contacts are the cause of the low-battery warning.

Some fixed the camera by inserting tiny pieces of plastic foam (i.e., spongy, like from "foam rubber" pillows) under the metal contacts. Used a small screwdriver to gently bend up each metal strip, and stuffed a small piece of foam under it. This provides enough force to keep the contact securely touching the battery. or You can also try the "toothpick trick" as described in various forums, and it seems to be working. There is a belief that there is a design flaw with the battery compartment door, or the springs that press against the battery. By wedging a toothpick under the battery contacts, it seems to force the contacts into the battery, seemingly helping with the problem that many are facing in this and other forums.
