Indoor/Outdoor Thermometer (630-0859)      Operating    Faxback Doc. # 6422

The temperature updates every 10 seconds, so it might take several
minutes for the temperature to register a rapid temperature change.

TEMPERATURE DISPLAY RANGES

Because the indoor temperature sensor is on the thermometer but the
outdoor temperature sensor is on an outside remote location, the outdoor
and indoor temperature display ranges are slightly different.

INDOOR TEMPERATURES

When the indoor temperature is above 122 degrees F or below 23 degrees F,
the display blanks out.

OUTDOOR TEMPERATURES

When the outdoor temperature is above 158 degrees F, HHH appears on the
display.  When the outdoor temperature is below - 58 degrees F, LLL
appears on the display.

Note:  When the indoor or outdoor temperatures return to within the
measurement range, the LCD display returns to normal.

MAXIMUM AND MINIMUM TEMPERATURES

The thermometer automatically stores in memory the maximum and minimum
indoor and outdoor temperatures since you last reset the thermometer or
replaced the battery.

READING THE MAXIMUM AND MINIMUM TEMPERATURES

To display the recorded maximum or minimum temperatures, press MIN or
MAX.  The minimum or maximum temperature recorded and MIN or MAX appear
on the display.

To return the display to the current indoor and outdoor temperatures,
press MIN or MAX again.  MIN or MAX disappears from the display and the
current indoor and outdoor temperatures reappear on the display.

CLEARING THE MAXIMUM AND MINIMUM TEMPERATURES

Press RESET to clear the maximum and minimum temperatures stored in
memory, MAX, MIN, and - 188.8 degrees E appear on the display for about
3 seconds.  Then the current temperature reading reappears on the
display.

USING THE STAND

You can use the stand on the back of the thermometer for easy viewing.
Simply lift the stand away from the thermometer and set the thermometer
on a flat surface.
