indoor temperature, 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.

RECEPTION OF SENSOR SIGNAL
OPERATING THETEMPERATURETATION
1. Remove the battery door and insert 2 new
AAA size batteries as per the polarity
information marked on the battery
compartment.
2. Press “RESET” key.
3. Slide “°C/°F” switch to select between °C and
°F.
4. Slide the battery door back on.
5. Press “CHANNEL” key to select the desired
channel.
Note When the sensor signal is received, the icon
“” will be displayed on the LCD.
OPERATING THE SENSOR
1. Remove the battery door and slide the
“CHANNEL” switch to CH 1.(When using
additional sensors, make sure each sensor is
assigned a different CHANNEL number.)
2. Insert 2 new AAA size batteries, matching
polarities(+/-).

4. Slide the battery door back on.
Note
Tip 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
