INSTRUCTION MANUAL
The Radio Controlled Clock with Thermometer
With the Radio Controlled Clock, you have the most accurate timepiece within
the continent. It can receive the time signal transmitted by the National
Institute of Standards and Technology (NIST), which is regulated by 3 atomic
clocks and deviates less than 1 second within 3,000 years. The NIST broadcasts
the time signal (WWVB, 60kHz) continuously from Fort Collins, Colorado. This
signal can be received anywhere in the continental USA that long wave (AM)
radio reception is possible with a portable radio. It is expected that the
signal can cover a distance of over 2,000 miles from the transmitter.
Therefore, your clock will receive the signal within the broadcast range
anywhere an AM signal can be received; generally the signal cannot be picked
up in massive metal and concrete structures unless near a window. In addition,
some environmental effects (see next page) may affect the transmitting
distance. For more information, please study the WWVB WEB page of NIST at:
http://www.boulder.nist.gov/timefreq/
Environmental Reception Effects
The Radio-Controlled Clock obtains the accurate time with wireless technology.
Same as all wireless devices, the receiving ability may be affected by, but
not limited to, the following conditions
- Long transmitting distance.
- Nearby mountains and valleys.
- Among tall buildings.
- Near railway, high voltage cable. etc. Near freeway, airport, etc.
- Near construction site.
- Inside concrete buildings.
- Near electrical appliances.
- Bad weather.
- Inside moving vehicles.
- Nearby metallic structures.
Location Precautions
This clock receives a radio wave much like a TV or radio. Be sure to locate it
near a window or some other locations where reception is good. Avoid the
following locations, which can interfere with proper reception.

GETTING STARTED
BATTERIES INSTALLATION
Batteries Installation of the Clock
- Open the battery cover of the main unit.
- Insert 3 “C” batteries in polarity(+) and(-) as indicated.
- Close the battery cover.
- The low battery icon will show in the indoor temperature window when your batteries need replacement.
Radio Controlled Clock Reception
Your radio controlled clock receives the offical time signal from Fort
Collins. Successful reception will activate the WAVE OK icon. If the clock
fails to receive the “WAVE” signal in the first reception sequence after power
up, it will repeat a 10-minute reception sequence every 3 hours. This
operation stops once the WAVE is received. The clock automatically refreshes
the WAVE each night. You can start reception of the time signal anytime by
pressing the WAVE button.
Note : Frequent use of this feature may affect battery life.
Unsuccessful Wave Signal Reception
If the automatic updates at 1 :00am is failed, the wave on top of the @ tower
and the OK icon will disappear.
If unsuccessful signal reception after battery installation or after reset,
the main unit will keep trying for 10 minutes every hour until time signal
reception is successful.
Interference
Signals from other household devices, such as entry controls, door bells and
home security systems, may temporarily interfere the Radio Controlled Clock
and cause reception failure. This is normal and does not affect the general
performance of the product. The transmission and reception of temperature
reading will resume once the interference has stopped.
Manual Clock Setting
If 20 minutes after power up your clock has not successfully received the time
signal, you may set the clock manually or the clock will continue an automatic
search each 3 hours until the signal is received. Best reception of the WAVE
is during the nighttime when the atmosphere allows a stronger signal to travel
farther from the transmitter. It is strongly recommended that you allow the
radio controlled clock one or two evenings to automatically catch the WAVE and
set itself.
If you decide to manually set the clock, please follow these easy steps :
- Slide the switch to TIME SET and the time will flash on the display. Press the HR and MIN buttons until you reach the desired time.
- Slide the switch to calendar and the year and date will flash on the display. Press the YEAR, MONTH and DATE buttons until you reach the desired calendar setting.
- Slide the Switch to the LOCK Position.
- Press the 12HR/24HR button to choose the desired display format. “AM” and “PM” display only in the 12HR format.
- Press the °C/”F button to choose the Centigrade or Fahrenheit scale. Both the indoor and outdoor temperature will display in the chosen scale.
Note : The display on the remote unit can also show Centigrade or Fahrenheit independent of the temperature scale chosen for the clock display.
Wall Mounting or Using the Stand
The main unit has a built in stand you can flip open to support the main unit
on a flat surface. You can close the flip and mount the unit on a wall. Drive
a screw into the wall until the head extends about 1/8 inch from the wall,
then locate the keyhole slot over the screw head and slide the Radio-
Controlled Clock down to make it secure.
Trouble – Shooting
- Press the “Reset” button when the clock is displaying irrelevant time even when the tower icon shows. This may happen when the external noise is severe enough to interfere with the time signal.
- Press the “Reset” button on the wireless transmitter if the readout is irrelevant or does not respond.
Care of Your Clock
- Avoid exposing your clock to extreme temperatures, water or severe shock.
- Avoid contact with any corrosive materials such as perfume, alcohol or cleaning agents.
- Do not subject the clock to excessive force, shock, dust, temperature or humidity. Any of these conditions may shorten the life of the clock.
- Do not tamper with any of the internal components of this clock. This will invalidate the warranty and may cause damage.
Warning : Changes or modifications to this unit not expressly approved by the party responsible for compliance could
void the user’s authority to operate the equipment.
ESD Press Reset Button
Under the environment with electrostatics discharge, the sample may
malfunction and require user to reset the sample.
Under the environment with radio frequency interference, the sample may
malfunction and require user to reset the
sample.
