How do I replace batteries in the ST01 series timer

The Intermatic ST01 uses a CR2 3 Volt-DC battery to operate the "click-clack" ON - OFF function of the timer.

In order to change the battery, simply pull down the flap just below small display screen. This is the manual switch that you can push to turn the timer on and off.

Just use your fingernail at the top of the door flap and pull down, it will open up and reveal another small tab. This is the battery holder/tray.

To open this, either use your fingernail or a small flat bladed screwdriver at the top to slide out the battery holder tray.

If you remjove and replace the battery within 30 seconds or less, you won't have to reprogram the time/day/date/year. Otherwise taking longer you'll have to reset the time and date feature of the timer.

Don't worry, the timer remembers your program ON - OFF cycles regardless of whether the battery is in the timer or not.

Hope you find this Very Helpful and best regards!

Intermatic Inc. is recalling about 240,000 in-wall electronic timers, models ST01 and EI600. When consumers try to replace the timer’s battery place a metal object through the battery tray slot, the object can reach internal metal contacts, posing a shock hazard to consumers.
