About the Atomic Clock
A clock is considered atomic if it has an accuracy of one second in a million
years. Consumer clocks are considered atomic if they attain this accuracy by
receiving a signal from an atomic clock. In North America, the National Institute
of Standards and Technologies operates an atomic clock in Colorado which
transmits the time codes via the radio station WWVB. The Acurite clock you have
purchased includes a built-in receiver which picks up the signal from the WWVB
station. For the best possible reception, place the main unit with the back side
facing Colorado. NOTE: Due to solar radiation in the atmosphere, the atomic
clock signal is weaker during the day. Most synchronization with the WWVB
atomic clock signal happens at night when there is less interference.
About the Wireless Sensor
This wireless weather station features a wireless sensor that provides wind,
temperature and humidity data and broadcasts this information to the main
display unit. This wireless sensor will provide accurate outdoor weather
conditions when placed properly. The wireless sensor contains sensitive
electronic components and a balanced anemometer (for wind speed
measurement). Care must be taken during setup and when considering
placement to make certain the unit is not dropped or struck with any falling
debris from trees or structures.

A/8/C Wireless Selection
To allow for more than one weather station and wireless sensor network
to be used in close proximity, the main unit and the wireless sensor have
a small switch labeled "A B C" within the battery compartments. This
switch selects one of 3 wireless modes to use, and both switches MUST
be set in matching positions (either A, B, or C) for wireless
communication to take place successfully.
Battery Choice & Temperature Range
Extended periods of cold temperatures

below -4°F / -20°C

can cause alkaline
batteries to function improperly. This will cause the outdoor wireless sensor to
stop transmitting temperature readings. Use lithium batteries in these low
temperature conditions to ensure continued operation for wireless sensors placed
outdoors. NOTE: Rechargeable batteries are not recommended due to higher
operating voltages
