How to use

Install the battery into the device with correct polarity, observing the positive (+) and negative (−) markings. Ensure the battery compartment contacts are clean and free of corrosion before insertion. Replace both batteries at the same time in devices that use multiple cells to maintain consistent voltage. Dispose of spent batteries according to local regulations for lithium cells and do not attempt to recharge primary lithium coin cells.

Usage recommendations

Store unused batteries in a cool, dry place away from direct sunlight and metal objects to avoid short-circuiting. For optimal device performance, use genuine Panasonic cells and replace batteries before the device indicates low power to prevent potential data loss in memory-backed electronics.
