How do I replace the battery in my Marathon TI030012 Minute Timer?

[DallasFitz]

If your Marathon TI030012 Minute Timer with Magnetic Clip displays a low battery indicator or stops working, a battery replacement is needed. The timer uses one AAA battery. Here's how to change it: First, remove any protective plastic film from the LCD screen. Then, locate the battery compartment on the back of the timer. Open the compartment by sliding the cover in the direction of the arrow. Insert a new AAA battery, making sure the positive (+) and negative (-) ends align with the markings inside the compartment. Close the battery cover securely. The timer should display "00:00" once the new battery is correctly installed and functioning. For any problems or if the timer still doesn't work after a battery change, consult the Marathon Watch Company Ltd. customer service information in your timer's manual for support.
