8 – Plug In Timer
To conserve battery power, as soon as setup and programming are
complete, plug the desired device into the timer and plug the timer
into a properly grounded outlet.
About the Battery
- The battery voltage is continuously
monitored. If a low voltage is
detected, the TOD display will
alternate between the current
TOD display and the “Lo” (low
battery) display (Fig. 16).
The timer requires two LR44 batteries to keep time up to three
months without power.
Replace the batteries as soon as possible after the low battery
display appears.
Change the batteries within one minute of unplugging in order to keep the time and programming settings. Afterwards, if the
display is wrong or displays MO, “12:00 AM”, reset the time
and programming.
While the batteries are removed, the timer will turn off the display to conserve power.
Dispose of the used batteries promptly according to local regulations. Keep batteries away from children.
