GETTING STARTED
POWER
Insert batteries before first use, matching the polarity
(+ and -).
NOTE Install batteries in the remote sensor before the
main unit. Press RESET after each battery change. Do not
use rechargeable batteries. We recommend that you use
alkaline batteries with this product for longer usage and
lithium batteries in temperatures below freezing.

REMOTE SENSOR
The sensor collects temperature readings approx. every
40 seconds and sends them to the main unit. The main
unit can collect data from up to 3 sensors.
To set up the sensor:
1. Slide open th e battery door.
2. Insert the batteries, matching th e polarit y (+ / - ).
Reset after each battery chan ge.
3. Select a channel. Make sure you use a different
channel for each sensor.
4. Close the bat tery compartme nt.
5. Secure th e sensor in the desire d location using th e
wall mount or table stand.
For best results:
• Place the sensor out of direct sunlight and moisture.
• Do not place the sensor more than 30 meters (100
feet) from the main (indoor) unit.
• Position the sensor so that it faces the main (indoor)
unit, minimizing obstructions such as doors, walls, and
furniture.
• Place the sensor in a location with a clear view to the
sky, away from metallic or electronic objects.
• Position the sensor close to the main unit during 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.
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).
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).
SENSOR DATA TRANSMISSION
The reception icon in the outdoor temperature area shows
the status.
ICON DESCRIPTION
Main unit is searching for the
sensor(s)
A channel has been found and
sensor signal is being received
The sensor cannot be found.
Search for the sensor or check
batteries
To search for a sensor:
Simultaneously, press and hold MEM and CHANNEL
for 2 seconds.
NOTE If the sensor is still not found, check the batteries,
obstructions, and remote unit location.
CLOCK
CLOCK RECEPTION
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.
The clock collects the radio signals whenever it is within
3218 km (2000 miles) of a signal.
NOTE Initial reception takes 2-10 minutes for first set up
or when RESET is pressed. Once complete, the reception
icon will stop blinking. If the signal is weak, it can take up to
24 hours to get a valid signal.
RECEPTION SIGNAL
STRONG WEAK NO SIGNAL
To enable and force a signal search:
Press and hold for 2 seconds.
To disable the signal reception:
Press and hold for 2 seconds.
SET CLOCK
If the clock signal reception is enabled and a signal is
being received the clock does not need to be manually
set.
To manually set the clock:
1. Press and hold MODE for 2 seconds.
2. Press and to change the settings.
3. Press MODE to confirm.
4. The setting sequence is: 12 / 24 hour format, hour,
minute, year, date / month format, month, date, and
display language.
