Batteries are not supplied with this product. You will need to purchase
2 x UM-3 (AA) 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.

2. Press A or V to change settings.
3. Press MODE to confirm.
Product can stand on detachable base or be mounted on a wall with a nail.
The main unit is shipped with a THN122N Thermo Sensor that col¬
lect temperature data and can be connected to 3 THN122N remote
sensors to collect additional temperature data. Additional sensors
sold separately.
To set up your remote sensor:
1. Open the remote sensor battery compartment with a small Phillips
screwdriver.
2. Insert the batteries, matching the polarity (+ and -) as shown in
the battery compartment.
Ml Standard Alkaline batteries contain signifcant amounts of
water. Because of this they will freeze in low temperatures of approxi¬
mately 10*F (-12”C). Disposable Lithium batteries have a much lower
threshold for temperature with an estimated freezing range of
below -40°F (-40X). The Liquid Crystal Display in outdoor thermom¬
eters will remain operational to -20°F (-28°C) with adequate power.
Wireless ranges can be impacted by a variety of factors such as ex¬
tremely 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 tow tem¬
peratures).
3. S et the channel switch to any channel. The switch is located in
the battery compartment.

DESCRIPTION
Channel
Channel 1 - 3. If you are using more
than one sensor, select a different
channel for each sensor.
4. Place the sensor near the main unit. Press RESET on the sensor.
Then, press CHANNEL and MEM at the same time 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 SENSOR
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.
For be9t results:
• Insert the batteries and select the channel and temperature
unit before you mount the sensor.
■ Place Ihe sensor out of direct sunlight and moisture.
• Do not place the sensor more than 30 meters (98 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.
You may need to experiment with various locations to get the best
results.
Data is sent from the sensor every 40 seconds. The reception Icon
shown In the Temperature Area shows the status.
