How to Reset an Emerson Smartset Clock

By Kallie Johnson

An Emerson SmartSet alarm clock utilizes patented SmartSet technology to automatically update the date or time displayed on the clock, even after power outages. The alarm clock relies on a lithium coin cell battery to maintain the clock and alarm settings and automatically update this information. The battery has a lifespan of three to five years. If the battery dies, it needs to be replaced. Once the battery has been replaced, the clock needs to be reset with current information in order for it to automatically update the date or time in the future.

Step 1

Use a small Phillips head screwdriver to remove the screw securing the battery holder to the backside of the alarm clock. Gently pull the battery holder out of the unit.

Step 2

Lift the old, lithium coin cell battery out of the battery holder. Place a new battery, positive (+) side up, in the battery holder. Slide the battery holder back into the unit. Secure back into the unit with the screw.

Step 3

Press and hold the "Month/Date" and "Time" buttons.

Step 4

Press the "Set +" button, while still holding the "Month/Date" and "Time" buttons once the display changes from Time to Year.

Step 5

Once the current year is displayed, release all of the buttons.

Step 6

Press and hold the "Month/Date" button.

Step 7

Press and hold the "Set +" button while still holding the "Month/Date" button once the display changes from Time to Month/Date.

Step 8

Release the buttons when the correct month and date appear on the display.

Step 9

Press and hold the "Time" and "Set +" buttons to set the correct time. Release the buttons when the current time is displayed on the screen.
