To Customers Who Use the PowerShot A530 / PowerShot A540 Digital Camera
Canon have discovered that, in a very small number of PowerShot A530 and PowerShot A540 digital cameras, the area around the battery cover on the bottom of the camera may become hot.
They have discovered that in cameras where the opening/closing spring on the inside of the battery cover sticks out beyond its regular position, if a battery is put into these cameras and the battery cover is closed, it causes a short-circuit and the following phenomena occur:
1) The bottom of the camera becomes extremely hot near the battery cover.
2) Batteries that are loaded are depleted quickly.
3) The number of shots that can be taken becomes extremely small.
PowerShot A530, PowerShot A540 Digital Cameras
PowerShot A530 and A540 digital cameras affected by this phenomenon will be repaired free of charge, regardless of warranty status. Accordingly, if the opening/closing spring on the inside of the battery cover of your PowerShot A530 or A540 digital camera sticks out, please do not use the camera. Instead, please visit Canon website and ring their call centre at your earliest convenience.
