Indoor/Outdoor Thermometer
(630-1026)                 Operation                  Faxback Doc. # 50951

Once you install batteries in the remote sensor and the main unit, the
remote sensor displays its local temperature and starts transmitting
signals about every 30 seconds.  The main unit starts searching for those
signals.

The temperature measured at the main unit appears on the bottom half of
its display (indicated by [IN]).  Once the main unit receives the remote
sensor's signal, the temperature measured at the remote sensor appears on
the top half of the display.

Note:  If the main unit does not receive or stops receiving a signal from
       the remote sensor, it displays - - . - instead of a temperature.
       Try manually searching for a signal (see "Manually Searching for a
       Signal" in Faxback Doc. # 50952) or resetting the main unit (see
       "Resetting the System" in Faxback Doc. # 50952).

Setting/Selecting The Display Channel

Your thermometer system's main unit can display information for up to
three different remote sensors.  Additional remote sensors (Cat. No.
63-1027) are available at your local RadioShack store.

Set CHANNEL 1/2/3 inside each remote sensor's battery compartment to a
different setting.

To display the temperature information for a remote sensor, repeatedly (if
necessary) press CHANNEL on the main unit you see the channel number you
set that sensor to use.

Note:  If you set two or more remote sensors to use the same channel, the
       main unit displays temperature information for the remote sensor's
       signal it received first.

Changing The Degree Format

You can view the temperature in Fahrenheit (F degrees) or Celsius (C
degrees) format on the main unit and on the remote sensor, and set each
separately.

To change the degree format for all temperatures displayed on the main
unit, set C/F degree on the back of the main unit to the desired setting.

To change the degree format displayed on the remote sensor, set C/F degree
inside the remote sensor's battery compartment to the desired setting.

Reading The Temperature Trend Display

The main unit displays the current temperature trend as rising, steady, or
falling.  The trend is based on the average temperature measured at the
selected channel's remote sensor within the last 30 minutes.

Note:  If your thermometer displays HH.H degrees or LL.L degrees, this
       means that the temperature has exceeded or fallen below the
       thermometer's measurement range (see "Specifications" in Faxback
       Doc. # 50954).  When the temperature returns to within the
       measurement range, the display returns to normal.

Reading The Kinetic Wave Display

The kinetic wave display (directly above the CHANNEL number) shows the
status of the signal being received by the main unit. The display consists
of three graduated arcs above a solid dot.

When the dot appears alone, the main unit is not receiving a signal.  When
the arcs appear one after another, the main unit is searching for or
receiving a signal from the selected channel's remote sensor.

Checking The Maximum/Minimum Temperatures

The main unit stores the maximum (highest) and minimum (lowest) local
temperatures and those of each remote sensor in its memory.

Follow these steps to recall the maximum and minimum temperatures stored
since the last memory reset.

1.  Repeatedly press CHANNEL on the main unit to select the desired
    channel.

2.  Press MEM once to recall the maximum temperature (MAX) and again to
    recall the minimum (MIN) temperature.

3.  Press MEM again to return to the current temperature display.

To clear the maximum and minimum temperature memory for the main unit and
the selected channel, and reset them to the current temperature, press
CLEAR.  The display resets and the current temperatures appear.

Using The Temperature Alarm

You can set the thermometer's temperature alarm to sound when the
temperature at a remote sensor exceeds or falls below upper and lower
temperature limits you set.

When a set temperature limit is reached at a remote sensor, an alarm
sounds at the main unit for 1 minute, the main unit displays the
information for that channel, and HI or LO and the temperature flash.  To
silence the alarm sooner, press ON/OFF TEMP AL on the main unit.

Follow these steps to set the alarm.

1.  Repeatedly press CHANNEL on the main unit to select the desired
    channel.

2.  Press HI/LO once to set the high temperature limit, (HI flashes) or
    twice to set the low temperature limit (LO flashes).

3.  Repeatedly press /\ to increase the alarm temperature setting one
    degree at a time.  Hold down /\ to increase it in five degree
    increments.

    Notes: When setting the alarm, the lower limit starts at -50 degrees
           C (-58 degrees F) or the last set alarm temperature.

           The highest limit you can set is +70 degrees C (158 degrees F).
           When you press /\ after reaching that limit, the range starts
           over at -50 degrees C (-58 degrees F).

4.  To turn on the alarm for the selected limit (HI or LO), press ON/OFF
    TEMP AL so HI or LO appears.  Or, press it so OFF appears to turn off
    that limit's alarm.

5.  Repeat Steps 2-4 (if desired) to set the other limit and turn its
    alarm on or off, then press HI/LO to return to the current temperature
    display.
