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), 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, transmitter.
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 forecast station is not able to detect the WWVB-signal (disturbances, transmitting
distance, etc.), the time and date can be manually set (see “program menu”).
Care and Maintenance
Do Not Mix Old and New Batteries
Do Not Mix Alkaline, Lithium, Standard, or Rechargeable Batteries
Do not expose the forecast station to extreme temperatures, vibration or shock. Keep dry.
Clean forecast station with a soft damp cloth. Do not use solvents or scouring agents.
The forecast station is not a toy. Keep it out of reach of children.
The forecast station is not to be used for medical purpose or for public information, but is determined
for home use only.
The specifications of this forecast station may change without prior notice.
Improper use or unauthorized opening of housing will void the warranty.
If the forecast station does not work properly, change the batteries and/or check the a/c cord
connection.
Position the Outdoor Transmitter
Once the forecast station shows the outdoor temperature/humidity, place it 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. transmitting range in open air is over 200 feet (60 meters) from outdoor
transmitter to forecast station.
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).
To achieve a true temperature/humidity 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.
