Thank you for your purchase of this Indoor / Outdoor
Thermometer. Please read these instructions carefully
and keep the manual well for future reference.
The receiver unit has a clear and easy-to-read display
that shows the indoor temperature, time, the maximum
& minimum temperature records in the past 24 hours
as well as the outdoor temperature measured and
transmitted from the remote sensors. It is able to
receive and display readings from up to 3 remote
sensors.
The 433 MHz technology means no wire installation is
required and you can place the sensors within 30m
(100ft) from the main (indoor) unit.
This product is designed to synchronize its date and
time automatically once it is within range of the WWVB-60
signal from the atomic clock in Fort Collins, Colorado.

Wireless ranges can be impacted by a variety of
factors such as extremely cold temperatures. Extreme
cold may temporarily reduce the effective range
between the sensor and the base station. If the unit’s
performance fails due to low temperature, the unit will
resume proper functioning as the temperature rises to
within the normal temperature range (i.e. no permanent
damage will occur to the unit due to low temperatures).

The time and calendar are radio-controlled. The current
time and calendar are automatically synchronized with
the atomic clock signal from Fort Collins, Colorado.
When used for the first time (after inserting batteries
or pressing “RESET” key), the clock will start to search
for the atomic clock signal and the signal reception
icon will flash for 5 minutes.

OVERVIEW

Standard Alkaline batteries contain significant amounts
of water. Because of this they will freeze in low
temperatures of approximately -12°C (10°F).
Disposable Lithium batteries have a much lower
threshold for temperature with an estimated freezing
range of below -30°C (-22°F).

cold winter months as below-freezing
temperatures may affect battery performance
and signal transmission.
The transmission range may vary depending on many
factors. You may need to experiment with various
locations to get the best results.
