USB Charge Port
Charge a smart phone, camera or other devices when the forecast station is plugged into a power outlet
with the included 5V AC adapter.
Note: This is a power-output charging port. It does not supply power to the projection alarm.
Connect your external device’s USB charging cable (not included) to the
USB charging port.
Charging times will vary.
USB Power Output: 0.5A maximum current. Charge 0.5A devices or
devices that are self-regulating.
Note: Some USB cables are for data transfer only and cannot be used for
charging. Make sure that the USB cable you use will charge your device. Most
USB cables included with mobile devices will work for charging.
ATOMIC SIGNAL SEARCH:
The LCD backlight, projection and USB charging port will momentarily turn off
while the station searches for the atomic signal. After the initial search, this
station will only search for the atomic signal after midnight.
Temperature Trend Icons
The indoor and outdoor temperature trend indicators are updated every 30 minutes. These trends
represent temperature changes over the past three hours.
Temperature rose more than 2°F /1°C in the past three hours
Temperature has not changed more than 2°F /1°C in the past three hours
Temperature fell more than 2°F /1°C in the past three hours
The temperature trend indicators are shown next to the indoor temperature and outdoor temperature
readings.
Outdoor Temperature Flashing
Low battery icon
present: Change batteries in the transmitter, and then hold the CH button until
the station beeps to search for the outdoor transmitter again.
End of Transmission Range: Move the transmitter closer to the display. Avoid obstructions in the
signal path. Keep transmitter and display away from electronics.
WWVB Radio-controlled Time
The NIST radio station, WWVB, 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 Projection Alarm. However, due to the nature of the Earth’s
Ionosphere, reception is very limited during daylight hours. The Projection Alarm will search for a signal
every night when reception is best. The WWVB radio station derives its signal from the NIST Atomic
Clock in Boulder, Colorado. A team of physicists continually measures every second of every day to an
accuracy of ten billionths of a second a day. These physicists have created an international standard,
measuring a second as 9,192,631,770 vibrations of a Cesium 133 atom in a vacuum. This atomic clock
regulates the WWVB transmitter.
WWVB Reception Icon
The icon with full signal strength will appear on screen in front of the date when the
reception of atomic time is successful.
The tower icon will show solid when the display has received the WWVB signal.
No tower icon displayed. The display was unable to receive a signal at this time.
8
Reposition the display for better signal reception or try again at bedtime.
The display will start searching at UTC: 07:00 and if no reception on the first attempt they will try
again at 08:00, 09:00 and 10:00. Each attempt will be at least 2 minutes and the most will be 10
minutes.
If there is no signal or too much interference, the receiver will only be on for 2 minutes.
If the signal is good, it may catch a signal in ABOUT 2-3 minutes.
If the signal is marginal it will try to catch a signal for up to 10 minutes.
ATOMIC SIGNAL SEARCH:
The LCD backlight, projection and USB charging port will momentarily turn off while the station searches
for the atomic signal. After the initial search, this station will only search for the atomic signal after
midnight.
Note: In case the Projection Alarm is not able to detect the WWVB-signal (disturbances, transmitting
distance, etc.); the time may be manually set.
Manual Signal Search
In normal mode, hold the RCC button until the reception icon appears to force a search of the WWVB
signal. The WWVB icon will flash during the search. If this icon disappears after the 2 minute search,
the radio time signal is not available at the moment.
Recommended distance to any interfering sources like computer monitors or TV sets is a minimum of
6 feet (2 meters).
Within ferro-concrete rooms (basements, superstructures, etc.), the received signal is naturally
weakened. In extreme cases, please place the unit close to a window and/or point its front or back
towards the Fort Collins, Colorado.
During nighttime, the atmospheric disturbances are usually less severe and reception is possible in
most cases. A single daily reception is adequate to keep the accuracy deviation below 1 second.
Note: In case the Projection Alarm is not able to detect the WWVB-signal (disturbances, transmitting
distance, etc.), the time and date can be manually set (see “program menu”).
Low Battery Icon
-
When this icon appears in the indoor (IN) data reading section, replace the batteries in the
Projection Alarm.
When this icon appears in the outdoor (OUT) data readings section, replace the batteries in the
outdoor transmitter.
Position the Outdoor Transmitter
Once the Projection Alarm shows the outdoor temperature, place the Projection Alarm and the transmitter
in the desired locations and wait approximately 1 hour before permanently mounting the transmitter to
ensure that there is proper reception. The transmitter should be mounted vertically, in a shaded,
protected area, at least 6 feet from the ground to avoid damage and ensure accurate readings. The
transmitter is water resistant, not waterproof and should not be placed anywhere it will become
submerged in water or subject to standing water or snow.
Choose a location for the transmitter that is within range of the Projection Alarm and under an overhang
for accuracy. Wireless transmitting range in open air is over 200 feet (60 meters) from outdoor transmitter
to Projection Alarm.
Option 1:
Install one mounting screw (not included) into a wall leaving approximately ½ of an inch
(12.7mm) extended.
Place the transmitter onto the screw, using the hanging hole on the backside.
Gently pull the transmitter down to lock the screw into place.
Option 2:
Insert the mounting screw (not included) through the front of the transmitter and into the
wall.
Tighten the screw to snug (do not over tighten).
9
To achieve a true temperature reading, mount where direct sunlight cannot reach the outdoor transmitter.
Mount the outdoor transmitter on a North-facing wall or in any well shaded area. Under an eave or deck
rail work well. The maximum transmitting range in open air is over 200-feet (60 meters). Obstacles such
as walls, windows, stucco, concrete and large metal objects can reduce the range. Place the transmitter
at least 6 feet in the air to improve signal transmission.
Position the Projection Alarm
1. The Projection Alarm has a wide base to sit on a desk or table.
2. Choose a location 6 feet or more from electronics such as cordless phones, gaming systems,
televisions, microwaves, routers, etc.
3. Place within range of the outdoor transmitter.
4. The maximum transmitting range in open air is 200-feet (60 meters). Obstacles such as walls,
windows, stucco, concrete, and large metal objects can reduce the range.
5. For best WWVB reception orientate the Projection Alarm with the front of the back facing Ft. Collins,
Colorado.
