INITIAL SET-UP
Remote Module—
(Battery Installation, °F/°C Selection)
1. Lift the stand, located on the back of the remote module, to expose the battery
cover and the RESET and °C/°F buttons.
2. Remove the battery cover.
3. Insert the batteries according to the polarities shown by the battery compartment
illustration.
4. Replace the battery cover.
5. Select the temperature display unit for the remote module by pressing the °C/°F
button.
Note: The temperature display unit of measure (°C/°F) of the remote module and the
main unit are independent of each other. The remote module may be set to display °C
and the main unit may be set to display °F and vice-versa. Changing the unit of
display on one does not affect the display of the other.
Main Unit—
(Battery Installation, °F/°C Selection)
1. Prior to installing the batteries into the main unit, insure the TIME SET switch,
located on the back of the unit, is set to the LOCK position.
2. Remove the battery cover.
3. Insert the batteries according to the polarities shown by the battery compartment
illustration.
4. Replace the battery cover.
5. Select the temperature display unit by pressing the °C/°F button.
Note: The temperature display unit of measure (°C/°F) of the remote module and the
main unit are independent of each other. The remote module may be set to display °C
and the main unit may be set to display °F and vice-versa. Changing the unit of
display on one does not affect the display of the other.
SET-UP TIPS
1. Insert batteries into the remote module before the main unit.
2. Place the main unit as close as possible to the remote unit. This will ensure easier
reception of signal.
3. Position the remote module within the effective transmission range (up to 30
meters/100 feet).
Note: The effective range is significantly affected by building materials and by where
the main unit and remote modules are positioned. Try various setups to insure proper
signal reception.
Important: Though the remote module is weather resistant, it should be placed away
from direct sunlight, rain, or snow.
SIGNAL RECEPTION
Atomic Clock—
The unit contains a pre-tuned internal radio receiver that receives a 60 kHz frequency
signal generated by the U.S. Atomic Clock. The U.S. Atomic Clock is located in
Boulder, Colorado and is operated by NIST (National Institute of Standards and
Technology).
Once the batteries have been installed, the unit automatically activates its receiver.
Upon successful reception of the signal from the Atomic Clock, the correct time-of-day
and date will appear on the display.
The unit may not receive a signal immediately. It may take as long as 72 hours to
receive a complete signal from the Atomic Clock. The clock will attempt a signal
reception for 10 minutes every 3 hours until it successfully receives the signal from the
atomic clock. While the unit is attempting to receive a complete signal for the first
time, the clock may be set manually (see the “Manual Clock/Calendar Setting”
section). Best reception often occurs between midnight and 4 am.
The successful reception of the Atomic Clock signal is dependent upon the positioning
and location of the unit. Insufficient signal strength or external electrical interference
may prevent the unit from receiving a complete signal. The main causes for poor
reception are heavily reinforced concrete and steel structures and/or placement of the
unit close to video or PC monitors. There are certain areas of the Eastern United
States where urban interference or signals from the United Kingdom’s Atomic Clock
may distort or interfere with the signal from the U.S. Atomic Clock.
Atomic Clock Signal Indicators
Indicates completed signal reception and synchronization with the Atomic
Clock.
Flashing, indicates that the unit is attempting to receive the signal from the
Atomic Clock.
Not flashing, indicates signal has not been successfully received.
If this symbol appears for more than 72 hours, the unit should be
repositioned for better reception.
Remote Module—
Once the batteries have been installed in the remote module, the unit automatically
activates its transmitter. Once the batteries have been installed in the main unit, the
main unit automatically activates its receiver. The clock will attempt to receive the RF
signal from the remote temperature module for 5 minutes. Upon successful reception
of the remote module’s signal, the display will show the remote temperature.
If no signal is received from the remote module, the main unit display will show “- - -”
for the remote temperature. Press the RE-SYNC button, located on the back of the
main unit, to initiate signal reception again.
The successful reception of the remote module’s RF signal is dependent upon the
positioning and location of the remote module. Insufficient signal strength or external
electrical interference may prevent the unit from receiving the signal. The main causes
