Model 308 battery replacement. Leave the unit plugged in and turned on and the battery should not need replacement for several years. It is only a back up for temporary power outages, the unit will function with or without it as long as it is plugged in and turned on. If you do not want "sunrise" turn your lamp off.Purchase Now!
Note: Use the buttons to stop sunrise while your lamp is on. While your lamp is on, don't use any other method of turning off the sunrise.
Unplugging, using a power strip switch, or anything else while the light bulb icon shows "ON" may damage the computer chip.
If you need to prevent sunrise for an extended period (going on vacation?) shut off the sunrise by using the buttons first, then unplug the unit. Or, shut off your lamp.
