Commissioning
1. First insert the battery to the thermometer, then to the exterior wireless
sensor (see Battery insertion and replacement).
2. On or after power on, the LCD display for 3 seconds, then detecting the
temperature / humidity / low voltage emission current temperature / humidity
data at the same time, LED flash, after entering the normal mode, each
synchronization cycle before the arrival of the detection temperature / humidity
and transmitting a data.
Battery insertion and replacement
When inserting or replacing batteries in the sensor, proceed as follows:
1. Remove the battery compartment cover.
2. Insert the battery, take care to maintain the correct polarity of the inserted
battery, follow the symbols at the bottom of the battery compartment.
3. Close the battery compartment cover.
Use alkali batteries, never use rechargeable batteries.
In case of low temperatures, lithium batteries are recommended.
Troubleshooting of sensor signal reception problems
If the sensor data fail to display, remove batteries from the sensor and from the
meteo station and repeat the procedure according to the “Commissioning”
section!
Also check:
1. if the wireless sensor and the thermometer are 1.5 m to 2 m from any sources
of interference such as computers, monitors, televisions and
other electric appliances.
