Replacing the Circuit Board Batteries
The ATR240 is equipped with (1) CR2032 3v Lithium Coin Cell battery on the Main
board. The battery should last approximately 1.5 to 2 years under normal operating
conditions. Do not attempt to replace the battery as it will void your warranty. If
your clock is already out of warranty you can attempt to replace the batteries yourself
but note that you could damage the board if you short out any components on the
circuit board. Avoid using metal objects to remove the batteries.
Note: all Time Recorder settings will be reset to factory defaults as soon as the Main
board battery is removed.
