Timex T110 User Manual

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. 

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.
