I am experiencing odd audio parameters being recalled by my CDC four / CDC four:m. Whats happening?

If you are finding that your CDC four or CDC four:m is recalling odd audio parameters when you are booting the console up, it maybe a sign of the internal backup battery failing.

The audio parameters of the CDC four and CDC four:m are stored in RAM memory, which is powered by a 3V lithium battery when the mains power is switched off. After a couple of years the battery will be below its optimum charge and this may result in unexpected audio parameters being recalled by the console when powered up.

We would therefore recommend that you change this battery for a new one every 12 months.

Below are links to specific instructions for replacing the internal on both the CDC four and CDC four:m:
