Temperature Alert Thermometer with Remote Sensor
(630-1011)                 Operation                  Faxback Doc. # 19308

IMPORTANT:  If the temperature falls below -58 degreesF (-50 degreesC), LLF
            (Low Low Fahrenheit) or LLC (Low Low Celsius) appears on the
            display and/or the display gradually fades out.  When the
            temperature returns to within the measurement range, the
            display returns to normal.

            If the temperature exceeds 158 degreesF (70 degreesC), HHF
            (High High Fahrenheit) or HHC (High High Celsius) appears on
            the display and/or the display goes blank.  When the
            temperature returns to within the measurement range, the
            display returns to within the measurement range, the display
            returns to normal.

            After you change the degree format or sampling cycle, you must
            press RESET. Otherwise, the thermometer continues to use the
            previous settings.  After you press RESET, the thermometer
            briefly displays -188E then the current temperature.

            Pressing RESET clears the LO and HI temperatures and resets
            both to the default settings (see "Setting the LO/HI Alarm
            Temperatures").

            Pressing RESET clears the MIN and MAX temperatures and resets
            both to the  current temperature (see "Displaying/Clearing the
            MAX/MIN Temperatures").

Changing the Degree Format

You can set the thermometer to display the temperature in either Fahrenheit
or Celsius.

1.  Set degreesC/degreesF on the back of the thermometer to degreesC for a
    Celsius reading, or degreesF for a Fahrenheit reading.

2.  Carefully insert a pointed object, such as a straightened paper clip,
    into RESET and press down gently to reset the memory.

Changing the Sampling Cycle

Your thermometer is preset to measure the temperature and update the
display every 60 seconds.  For a more frequent measurement, you can change
the sampling cycle time to 10 seconds.

Follow these steps to change the sampling cycle.

1.  Set FAST/NORMAL on the back of the thermometer to FAST for a
    temperature reading every 10 seconds, or to NORMAL for a reading every
    60 seconds.

    NOTE:  To conserve battery power, use the NORMAL setting.

2.  Carefully insert a pointed object, such as a straightened paper clip,
    into RESET and press down gently to reset the memory.

Measuring the Temperature

To measure the temperature through the remote sensor, remove the battery
compartment cover, then plug the sensor cord into the jack inside the
compartment.

To measure the temperature at the thermometer, simply unplug the remote
sensor's cord from the jack inside the battery compartment.

Displaying/Clearing the MAX MIN Temperatures

To view the highest (MAX) and lowest (MIN) temperatures recorded since the
last memory reset, press MODE until they appear on the display.

To reset the MAX temperature, press RESET MAX on the back of the
thermometer.  To reset the MIN temperature, press RESET MIN.

To reset both the MAX and MIN temperatures at the same time, press MEMORY
CLEAR on the front of the thermometer.

NOTES:  After you press RESET MAX, RESET MIN, or MEMORY CLEAR, the
        thermometer briefly displays -188, then the current temperature.

        Pressing RESET also clears the MIN and MAX temperatures and resets
        both to the current temperature.

Setting the LO/HI Alarm Temperatures

You can set the thermometer to sound an alarm when a set low (LO) or high
(HI) temperature is reached.  The thermometer has preset LO (50 degreesF,
10 degreesC) and HI (86 degreesF, 30 degreesC) alarm settings. 

To change the LO and HI settings, follow these steps.

1.  Press MODE so the LO and HI temperatures appear on the display.

2.  Repeatedly press LO and HI to set the desired low and high
    temperatures.

NOTES:  When setting LO and HI, the display cycles upward only.  For
        example, when the display reaches the upper limit (limit (158
        degreesF, 70 degressC), it drops back to the lower limit (-58
        degreesF, -50 degressC) and resumes cycling upward.

        To rapidly change the settings, press and hold down LO or HI.

        The LO setting must be lower than the currently displayed
        temperature and the HI setting must be higher than the currently
        displayed temperature.  Otherwise, the alarm will not sound.

Using the Alarm

To turn on the alarm, set ALARM ON/OFF to ON.

When the temperature exceeds either the LO or HI setting, the alarm sounds
for 1 minute then sounds for about 3 seconds every minute for 12 hours,
and the LO or HI temperature, whichever triggered the alarm, continuously 
flashes.

NOTE:  When you press MODE while the alarm is sounding, LO or HI, whichever
       triggered the alarm, flashes on the display.

To silence the alarm before it automatically stops, press either MEMORY
CLEAR, RESET MIN, RESET MAX, LO, or HI.  The alarm sounds again the next
time the temperature exceeds the LO or HI setting.

To silence the alarm and turn it off so it will not sound again, set ALARM
ON/OFF to OFF.
