TIME CALIBRATION SIGNAL RECEPTION PRECAUTIONS
ALM OFF
The alarm does not sound.
Stopping the Alarm
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 reach a distance of 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 below) may affect the transmitting distance.
Receive unsuccessful
The alarm sounds at the preset time for one minute.
The alarm time appears in place of the date on the display whenever the Alarm Mode selector（⑤） is set to
ON or SNOOZE. The backlight also turns on for the first four seconds that the alarm sounds.
The alarm sound changes over four levels as it sounds.

When RF communication cannot be successful.
When LCD dimmed.
1. Open the stand so you can see the back cover.
2. Remove the back cover screw, and then open the back cover.
3. Remove both old batteries.
4. Load full set of new batteries. Make sure that their positive (+) and negative (-) ends face in the correct
directions.If you load batteries incorrectly, they can burst and damage the product.
5. Replace the back cover and secure it in place with the screw.
6. Press the RESET button (⑮). Be sure to press the RESET button (⑮) after replacing batteries.
7. Press the RE-SYNC button (⑪).

Unsuccessful Signal Reception
The antenna icon disappears from the display when a signal receive operation is unsuccessful. If this happens, try
changing the position or orientation of the clock, and press the WAVE button ( ④) to receive again.
The time calibration signal includes both Standard Time and Daylight Saving Time (summer time) data.
Battery precautions
Keep batteries out of the reach of small children. If a battery is accidentally swallowed, contact your physician
immediately
Be sure to load the batteries with their positive (+) and negative (-) ends facing correctly.
Never charge the batteries that come with the clock.
Should batteries ever leak while in the clock, wipe out the fluid with a cloth, taking care not to let any get into
your skin.
Replace the batteries at least once a year, even if the current batteries are working properly.
The batteries that come with the clock lose some of their power during transport and storage.
THERMOMETER FUNCTIONS
Both the main unit and the sub-unit are equipped with their own temperature sensors. Temperature data measured
by the sub-unit is sent by wireless transfer to the main unit. You can toggle the main unit display between the main
unit temperature reading and the sub-unit temperature reading. This make it possible to view both the indoor and
outdoor temperature on the main unit display.
Temperature Measurements
Both the main unit and the sub-unit take temperature measurements every 16 seconds.
The temperature display shows LO for temperatures below - 58 ¡F (-50 ¡C) and HI for temperatures above
158 ¡F (70 ¡C).
Though temperature readings are displayed up to 32 ¡F(0 ¡C). and greater than105¡C (41 ¡F), note that such
readings are actually outside the guaranteed temperature range of this clock.
Switching between Celsius and Fahrenheit
Push the ¡C / ¡F button( ⑩) to select either Fahrenheit (¡F) or Celsius (¡C).
Fahrenheit (¡F)
Celsius (¡C)
Do not use or store this clock in areas exposed to temperature extremes, strong magnetism, strong vibration, or
strong impact.
Heat can shorten battery life and cause malfunction. Keep the clock away from heaters and direct sunlight when
using it.
Never use the clock in a bathroom or any other area subject to high humidity.
Never try to take the clock apart. Doing so can cause malfunction.
To clean the clock, use a soft, dry cloth or a cloth moistened in a solution of water and a mild neutral detergent.
Wring out all excess moisture from the cloth. Never use thinner, benzene, alcohol or other similar agents.
Keep your manual and all information handy for future reference.
USING THE WEATHER FORECAST FEATURE
A built in pressure sensor makes it possible to forecast upcoming weather over the next 12 hours based on changes
in barometric pressure. Note that these forecast are not absolutely accurate, and are intended for general
reference only.
Weather Forecasts
Barometric pressure readings are taken every 15 minutes. Weather forecast are based on the last six
readings. Upcoming weather forecasts are displayed using the graphic indicators shown below.
