Review Battery Tips 1. Replace the batteries as soon as LO Batt flashes in the display. The LO Battery indicator flashes in the display one month before the batteries run down completely. 2. Always use fresh AAA alkaline batteries. Non-alkaline batteries do not last as long and can leak, causing thermostat damage. 3. 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. 4. As a precaution, replace the batteries when leaving your home for more than a month to prevent your heating/cooling system from shutting down if the batteries run down completely. 57 69-1725-1
