AUTO POWER OFF FUNCTION
If this unit is left unattended for about 1 minute, it will
automatically power down from the current mode and enter
the stand-by mode, showing room temperature, time, and
date. The display alternates between time and date in a
pattern that repeats every minute as follows: time 11 sec /
date 4 sec / time 11 sec / date 4 sec / time 30 sec.
BATTERY REPLACEMENT

The stand-by mode shows NOTHING on the display except
the time and date. When the ON/MEM button is pressed,
NOTHING is displayed except the battery mark blinking 12
times followed by OFF for 1 second and then the display
returns to NOTHING except the time and date.
