You'll occasionally need to replace the battery in your Time Timer MOD.
To replace the battery, please follow the instructions below:
1. Open the battery compartment on the back of your Time Timer MOD using a small, Phillips head screwdriver.
The battery compartment is securely closed by a small screw to adhere to the Consumer Product Safety Improvement Act (CPSIA) standards. Although the timer is not a toy, we do realize the product may be used around small children. Therefore, the battery compartment is securely closed by a small screw to adhere to CPSIA standards.
2. Insert the AA battery negative side (the flat end) first into the compartment so that it is touching the spring.
3. Replace the cover to the battery compartment and tighten using the small, Phillips head screwdriver.
