M1713
After the batteries are completely dead, the
bAt-Lo indicator will disappear, leaving a
completely blank display.
Press down on left ends of batteries to remove.
If you insert the new batteries within 20 to 30
seconds of removing the old ones, you will not
have to reprogram the thermostat. However, if
the display is blank, the batteries are dead or
incorrectly installed and you will have to
reprogram. See pages 14 to 17 to reprogram.
IMPORTANT
Although the thermostat has a low
battery indicator, replace the batteries
once a year to prevent the thermostat
and heating/cooling system from
shutting down due to lack of battery
power.
As a precaution, when leaving home for longer
than a month, change batteries before you
leave to prevent system from shutting down
due to lack of battery power.
