Positioning of World Time Center
Hanging
Hole
The World Time Center has been designed to be hung on a wall. To mount please do the following:
1.Fix a screw (not supplied) into the desired wall, leaving the head extended out the wall by about 5 mm as indicated above.
2.Using the World Time Center's hanging hole on the back of the unit, carefully hang it onto the screw. Always ensure that the product securely locks onto the screw head before releasing.
Note:
Users are recommended to check that the WWVB time signal is properly received before permanent standing, hanging or mounting of World Time Center. Should the World Time Center not pick up the signal from the desired location, then relocate slightly. Once the signal is received, mount your system units permanently.
Important Notes
•Avoid placing the World Time Center where it can be exposed to sudden changes in temperature, i.e. direct sunlight, extreme cold and wet/moist conditions since the design of this product is for indoor use only. This will help to avoid any inaccurate readings and any possible damage to the unit.
•Should the World Time Center be exposed to extreme and sudden temperature changes, it will lead to rapid changes in its readings and thereby reduce its accuracy.
Care and Maintenance
•Avoid placing the units in places prone to extreme temperatures, vibration and shock as these may cause damage and inaccurate readings.
•When cleaning the World Time Center and Temperature Sensor's displays and casings, use a soft damp cloth only. Do not use solvents or scouring agents as they may mark the LCDs and casing.
•Do not submerge the units in water.
•Immediately remove all low powered batteries to avoid leakage and damage. Replace only with new batteries of the recommended size.
•Do not make any attempts to repair the units. Return them to their original point of purchase for repair by a qualified engineer. Opening and tampering with the units may invalidate their guarantee.
Battery Change
For best performance, batteries to all units should be replaced when the low battery indicator is displayed on the LCD of the World Time Center and the Outdoor temperature sensor or at least once a year to maintain maximum running accuracy.
Please help in the preservation of the environment and return used up batteries only to an authorized depot.

Subject Index
Here the interested user will find a number of additional informations regarding the function of this Wallclock Weather Station. Their knowledge however is not necessary for efficient operation of this system.
Clock, Radio Controlled
The time base for radio controlled time and date is a operated by the NIST radio station WWVB in Ft. Collins, Colorado. WWVB broadcasts are used by millions of people throughout the United States to synchronize electronic products like clocks, clock radios and wristwatches. WWVB continuously broadcasts time and frequenzy signals at 60kHz and the time information received and displayed is absolutely accurate regardless of summer or wintertime.
Software Operations
•WWVB Time Signal
Once every day with reception within 12:00am to 6:00am, after every setup or reset and after leaving the programming mode with the time manually changed the software of the World Time Center will start a reception of the WWVB time signal.
•Indoor Temperature and Humidity
The software of the World Time Center will perform measurements of the current indoor temperature every 20 seconds, the current indoor humidity every 1 minute. In programming mode and while any one key is pressed no WWVB reception will take place.
