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
transmit the time codes via the the radio station WWVB.The signal is
transmitted in a very low frequency [60,000 Hz]. The Acurite® clock you have
purchased includes a built-in receiver which picks up the signal from the WWVB
station. Dueto solar radiation in the atmosphere, the atomic clock signal is
weak during the day. Most synchronization with the WWVBatomic clock signal
happens at night when there is less interference.

Operating Range of Batteries 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.

(3 • PLACEMENT )
Now that setup is complete, you must choose a location to place the wireless
sensor and the main unit. The wireless sensor MUSTbe placed less than 100
feet away from the main unit.
This wireless thermometer uses radio frequency for communication, which is
susceptible to interference from other electronic devices and large metallic
items or thick walls. Always place both units at least 3 feet away from
appliances ITV, microwave, radios, etc. Ior objects Ilarge metal surfaces, thick
stone walls, etc. Ithat may interfere with the wireless communication.

Placement of Main Unit
Place the main unit in a dry area free of dirt and dust. To help ensure
an accurate indoor temperature measurement, be sure to place the
main unit out of direct sunlight, and away from any heat sources or
vents in your home.
There are 2 placement options for the the main unit. Youmay hang
the main unit on a wall using the integrated hang hole on the back.
Alternatively, you may use the fold out "table stand" to place the
main unit on a table top or other flat surface.
Placement of Sensor
The wireless sensor MUSTBE PLACEDOUTDOORSto observe
outdoor temperatures and relay the outdoor temperature to the main
unit display. The wireless sensor must be placed less than 100feet
from the main unit.
The wireless sensor is water resistant and is designed for outdoor
use. However, to extend the life of the product, place the wireless
sensor in an area protected from direct weather elements. Toensure
an accurate outdoor temperature measurement, be sure the wireless
sensor is placed out of direct sunlight and away from any heat
sources.

Wireless Reception
The main unit has a wireless signal reception
icon in the temperature display area and in the
clock display area. If there are a low number of
"bars" present, you may experience no
temperature display I..__..Ior clock inaccuracy.
In either case, you may need to relocate one or
both of the units. If most or all 4 of the bars are
present, wireless reception is good and no action

Troubleshooting
Problem Possible Solution
Bad Temperature Relocate the main unit and/or the wireless
sensor. Both units must bewithin 100feet
Reception from each other. Make sure both units are
placed at least 3 feet from other electronic
T Ill appliances and devices that may interfere
no bars with the wireless communication [such as
TVs, microwaves, computers etc]. NOTE:It
may take up to 20 minutes for the main unit
to resynchronize with the sensor when
batteries are replaced.
Bad Atomic Clock Relocate the main unit. Make sure main unit
is placed at least 3 feet from other electronic
Reception appliances and devices that may interfere
T Ill with the wireless communication [such as
TVs, microwaves, computers etc]. Large
no bars metallic surfaces will also interfere with the
atomic clock signal.
No Outdoor If wireless reception is bad [no bars]. see
Temperature or "Bad Reception··section above.The wireless
Humidity Display ID setting on each unit must match for both
units to communicate properly. See "Set
