occur, replace the battery immediately. Do not leave a low or dead battery in the clock.

To replace the battery

1. Remove the battery cover.

• Rotate the battery cover so its

mark moves from CLOSE to OPEN.

2. Remove the old battery.
3. Load a new battery, making sure that its positive (+) and negative (–) ends are facing correctly.

• Loading a battery incorrectly can cause it to burst and damage the clock.

4. Replace the cover.

• Place the battery cover onto the clock so its

mark is initially aligned with OPEN. Next, rotate the cover so


mark moves from OPEN to CLOSE.

• The battery cover can fall off or water can get into the clock if the cover’s

mark is not pointed at CLOSE.

• Dirt or dust on the battery compartment gasket can allow water to get into the clock. Use a soft, dry cloth to

wipe the gasket clean before replacing the battery cover.
