up the Weather Projection Station again. Proceed from step 1 in “Setting

Up”,“Battery Installation” or “How to use the Projector Adaptor”.

HOW TO USE THE PROJECTOR

The projector projects the current time and the current outdoor temperature onto the ceiling, preferable within a darkened room. The projection image can also be adjusted in 4 upright positions, each with a rotation of 90º by

using the ABOUT WWVB RADIO CONTROLLED TIME key .

TO PROJECT THE TIME OR TEMPERATURE ONTO A FLAT SURFACE:

The projector will only project the current time, outdoor temperature or alternate between time/outdoor temperature only.

1.Point the projection lens to the appropriate direction (maximum distance of the projection is 6 feet/2 meters).

2.Press the DISPL key to select the desired mode for the projection. There are 3 display modes:

M0 – projecting the current time only.

M1 – projecting the current outdoor temperature only.

M2 – projecting by switching the display of the current time and the current outdoor temperature for every 5 seconds.

3.Adjust the projection image in an upright position with the Manual background key.

Note:

If more than one Thermo-hygro Sensor is used, only the temperature from sensor 1 will be projected.

Note:

The projection brightness is not adjustable as it is constantly set at its brightest level.

ABOUT WWVB RADIO CONTROLLED TIME

The NIST (National Institute of Standards and Technology—Time and Frequency Division) WWVB radio station is located in Ft. Collins, Colorado, and transmits the exact time signal continuously throughout the United States at 60 kHz. The signal can be received up to 2,000 miles away through the internal antenna in the Weather Projection Station. However, due to the nature of the Earth’s Ionosphere, reception is very limited during daylight hours. The Weather Projection Station will search for a signal every night when reception is best.

The WWVB radio station receives the time data from the NIST Atomic clock in Boulder, Colorado. A team of atomic physicists is continually measuring every second, of every day, to an accuracy of ten billionths of a second per day.

These physicists have created an international standard, measuring a second
