What is Radio Controlled Clock 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 deviate less than 1 second within 3,000 years. The NIST broadcasts the time signal ( WWVB, 60kHz ) continuously from Fort Collins, Colorado.
Feature • Receive 60kHz WWVB signal transmitted by NIST at Fort Collins Colorado • Automatic time adjustment after signal reception • Calendar with day of the week display • Hour, minute and second display • Indoor temperature and remote temperature • Centigrade or Fahrenheit readout • Indoor temperature measurement range from -20°C ~ 70°C ( -4°F ~ 158°F ) • Outdoor temperature measurement range from -50°C ~ 70°C ( -58°F ~ 158°F ) • Temperature resolution 0.1°C ( 0.
Battery Installation Battery Installation of the Main Unit • Open the battery door. • Load full set (2pcs AA size battery) of new batteries in polarity (+) and (-) as indicated. • Close the battery door. Battery Installation of the Remote Unit • Open the battery door. • Load full set (2pcs AA size battery) of new batteries in polarity (+) and (-) as indicated. • Close the battery door. Warning : Do not mix old and new batteries.
Wave Signal Receive Operation The main unit automatically receives time signal everyday at 02:00am and makes any required adjustment to the time setting, indicated by the flashing tower icon . If the time signal is successfully received, the tower icon will stop flashing and will display steadily. A WAVE OK indicator will appear on display. Important : Do not perform any button or switch operation while a signal receive operation is in progress.
Check IN / REMOTE Temperature The indoor temperature is displayed on the INDOOR temperature field and the OUTDOOR temperature will be shown on the OUTDOOR temperature field. Display Unit The default unit for temperature is °C, press °C/°F button will toggle the display unit of temperature between °C and °F.
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 Atomic Clock down to make it secure. The remote unit comes with a wall mount holder which can hold the unit on wall, or just place it on a flat surface.
