TABLE STAND OR WALL MOUNT
BATTERIES
Use the stand on the back of the product, or mount it on
a wall with a nail.
Batteries are not supplied with this product. You will need
to purchase 2 x UM-4 (AAA) 1.5V alkaline batteries for
the main unit, and 2 x UM-4 (AAA) 1.5V alkaline batteries
for the remote sensor.
Insert batteries before first use, matching the polarity as
shown in the battery compartment. For best results, install
batteries in the remote sensor before the main unit. Press
RESET after each battery change.
NOTE Do not use rechargeable batteries.

This product is shipped with a THR122NX Thermo
Sensor that collects Temperature data. Data can be
collected from only 1 sensor.
1.
Open the remote sensor battery compartment with
a small Phillips screwdriver.
2.
Insert the batteries, matching the polarity as shown
in the battery compartment.
3.
Selec any channel.
4.
Place the sensor near the main unit. Press RESET
on the sensor. Then, press and hold SEARCH on
the main unit to initiate signal sending between the
sensor and the main unit. The reception icon on
the main unit will blink for approximately 3 minutes
while it is searching for the sensor. (Refer to the
Data Transmission section for more information.)
5.
Close the remote sensor battery compartment.
6.
Secure the sensor in the desired location using the
wall mount or table stand.
• Position the sensor close to the main unit during
cold winter months as below-freezing
temperatures may affect battery performance and
signal transmission.
You may need to experiment with various locations to
get the best results.
Standard Alkaline batteries contain signifcant amounts
of water. Because of this they will freeze in low
temperatures of approximately 10ºF. Disposable Lithium
batteries have a much lower threshold for temperature
with an estimated freezing range of below -40ºF. The
Liquid Crystal Display in outdoor thermometers will
remain operational to -20ºF with adequate power.
For best results:
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.
• Insert the batteries and select the channel before
you mount the sensor.
• Place the sensor out of direct sunlight and
moisture.
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).
• Do not place the sensor more than 98 feet
(30meters) from the main (indoor) unit.
• Position the sensor so that it faces the main
(indoor) unit, minimizing obstructions such as
doors, walls, and furniture.
EN
• Place the sensor in a location with a clear view
to the sky, away from metallic or electronic
objects.
SETUP SENSOR
DATA TRANSMISSION
TEMPERATURE
Data is sent from the sensor every 80 seconds. The
reception icon shown in the Outdoor Temperature
Area shows the status.
This product can display current, minimum, and maximum
temperatures collected by the remote sensor and main
(indoor) unit.

DESCRIPTION
Main unit is searching for
sensor.
A channel has been found.
Outdoor data is collected and displayed every 80
seconds. Indoor data is collected and displayed every
10 seconds.
SELECT TEMPERATURE UNIT
Press the ºC / ºF switch into the desired location. The
switch is located in the main unit battery compartment.
The setting for the main unit overrides the remote sensor
setting.
Channel 1 is selected
--- shows in Outdoor
Temp Area
The selected sensor cannot
be found. Search for the
sensor or check batteries.
MINIMUM / MAXIMUM RECORDS
SEARCH FOR SENSOR
Press MEMORY to toggle between current, maximum
(MAX) and minimum (MIN) records. To clear the records,
press and hold MEMORY for 2 seconds. A beep will
sound to confirm that the memory has been cleared.
To search for a sensor, press and hold SEARCH for
2 seconds.
NOTE If the sensor is still not found, check the
batteries, obstructions, and remote unit location.
NOTE Signals from household devices such as
doorbells, electronic garage doors, and home security
systems may cause temporary reception failure. This
is normal and does not affect general product
performance. The reception will resume once the
interference ends.
RESET SYSTEM
The RESET button is located main unit battery
compartment. Press RESET when you change the
batteries and whenever performance is not behaving
as expected (for example, unable to establish radio
frequency link with remote sensor).
SAFETY AND CARE

handled properly. Observe the following guidelines:
Do not subject the main unit to extreme force, shock,
or fluctuations in temperature or humidity.
•
Do not tamper with the internal components.
•
Do not mix new and old batteries or batteries of
