TIME CALIBRATION SIGNAL RECEPTION PRECAUTIONS 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. Inside, among buildings, or near neon signs Inside a vehicle Near refrigerators or other household appliances, near office equipment, mobile phones or wireless LAN devices. Near a construction site, airport, or other sources of electrical noise, underground or in tunnels, near railroads, highways, or radio stations with interfering frequencies. Near high-tension power lines Among or behind mountains Signal reception is normally better at night than during the day. Radio interference can make signal reception impossible. Strong electrostatic charge can result in the wrong time being set. If you are in an area where proper time calibration signal reception is impossible, the clock keeps time with the precision noted in "SPECIFICATIONS". For more information, please study the WWVB WEB page of NIST at:

MAIN UNIT/SUB UNIT COMMUNICATION PRECAUTIONS Certain environmental cinditions can greally reduce the communication range. Locating the sub-unit near a device that transmits radio signals using the same frequency as this product can cause communication failure of this product. Avoid using multiple product in the same area. Doing so can mixing of their signals. USING THE CLOCK Any of the following procedures can be used to set current date and time. Auto receive of the time calibration signal Manual receive of the time calibration signal Manual setting without using the time calibration signal Alarm Off Current time

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. 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 (

Replace the battery compartment cover. 5. Press the RESET button (). Be sure to press the RESET button () after replacing batteries. To replace sub-unit batteries Replace batteries whenever the following :
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 (). Be sure to press the RESET button () after replacing batteries. 7. Press the RE-SYNC button (). 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 (-50C) and HI for temperatures above 158F (70 C).
Though temperature readings are displayed up to 32F(0 C).and greater than105C (41F), note that such
