Battery Backup Installation
It is strongly recommended that a 9-Volt battery be installed into the unit, as directed below, in order to activate this product’s Battery Backup feature. In the event that the AC power cord is disconnected or a power failure or other interruption occurs, the Battery Backup will maintain clock and alarm settings for the life of the battery. During any interruptions the clock display will be blank, but time and alarm settings will be saved and automatically restored when AC power is again active.
To install the battery:
1.Open the battery compartment cover.
2.Install one 9-Volt battery (alkaline is recommended for longer life), making sure that the large terminal matches to the large outlet.
The Battery Backup Indicator LED is located in the lower-right-hand corner of the display. The LED will light when no battery is installed, or when the installed battery is low on power.
After installing the battery and reading the Maintenance notes, plug the AC power cord into an outlet, being sure to match the wide blade of the plug to the wide slot of the outlet. Never force the plug into an outlet. When the unit is connected to AC power for the first time, the display may blink until the time is set.
Note: You should replace the battery every six months, or after any extended power outage that could drain the battery power.
