Hi, thank you for contacting My name is Russell. I will do my best to provide the right answer to your question.

First try replacing the batteries.... no, you've already tried that.

How old is the alarm?

Where has it been operating?

If it has been 7 years, the ERR message means it is at the end of its life, and must be replaced as a whole.

Try this: press and hold down the Peak Level Memory button.

If the digital display now shows E09 then that confirms it: your alarm is at the end of its lifetime (of about 7 years in-use.)

Your smoke alarm will not detect CO in this mode. It is strongly recommended that you replace it with a new one.
