Consider the distance the clock is located away from other electronic in the
home.
Resistance:
Obstacles such as walls, windows, stucco, concrete, and large metal objects can
reduce the range.
When considering the distance between the transmitter and the clock (330 feet
open air) cut that distance in half for each wall, window, tree, bush or other
obstruction in the signal path.
Closer is better.
Do not mount the transmitter on a metal fence. This significantly reduces the
effective range.
Interference:
Consider items in the signal path between the transmitter and the clock.
Sometime a simple relocation of the transmitter or the clock will correct the
interference issue.
Windows can reflect the radio signal.
Metal will absorb the RF (radio frequency) signal.
Stucco is held to the wall by a metal mesh.
Transmitting antennas (ham radio, emergency dispatch center, airports, military
base etc.)
Electrical wires (utilities, cable etc.)
Vegetation is full of moisture and reduces signal.
Dirt: Trying to receive a signal through a hill is difficult.
Projection Alarm Clock
How tall are the Time Numbers?
The time numbers are 0.59 inches tall.
12-Hour or 24-Hour Time Format
Display the time in 12-hour or 24-hour format
Default is 12-hour time.
Use the Program Menu
to switch time formats.
Power Requirements
This clocks powered by a 6 volt AC power adapter
Alternatively, optional 3-AA alkaline batteries
Inaccurate Indoor Temperature Reading
Look for heat sources such as sunlight, door or window frames, or reflected heat
of cold.
