WIRELESS INDOOR/OUTDOOR HUMIDITY AND TEMPERATURE MONITOR
INSTRUCTION MANUAL
Model No. TX-2B
Introduction
Congratulations on your purchase of the wireless indoor/outdoor temperature monitor. You will now be able to
know the outdoor/indoor temperature while sitting inside.
Components
1. One base station unit (Receiver)
2. One remote sensor (Transmitter)
3. Four AAA size batteries (included)
*Although the remote sensor is designed to be rain-proof, the remote sensor must be always placed
upwards so that rain won’t get inside the sensor through the vent holes on the bottom of the senor
which functions to let the remote sensor detect the environmental temperature more precisely and
quickly.
Indoor Base Station (Receiver) Features
1. LCD display: Displays the current outdoor temperature and indoor temperature
2. Battery Compartment: Holds 2 AAA batteries to power the unit
3. Tabletop and wall-mounted design
4. Indoor Temperature range: -4 °F ~ 158°F (-20 °C ~ 70 °C).
5. Temperature display unit: °C and °F selectable
6. Temperature Resolution: 0.1 °C/°F
7. Low battery indication
Buttons
CHANNEL/SYNC: Press once to display the temperature readings from up to 3 outdoor remote sensors;
Press and hold this button to enter the synchronization mode.
°F /°C /: Press to select the temperature display in ºC or ºF.
Outdoor Remote Sensor (Transmitter) Features
1、Battery Compartment: Holds 2 X AAA batteries to power the unit
2、Rain-proof and wall-mounted design
4. Outdoor Temperature range: -58°F ~ 158°F (-50 °C ~ 70 °C)
Buttons
CHANNEL Selector (1,2,3): Slide to set Channel 1,2 or 3.
RESET: Press once to reset the remote sensor.
TX: Press to send temperature data to the receiver manually.
Battery Installation and Setup
1、Open the battery compartment of the remote sensor as below Figure;
2. Slide the channel selector switch inside the battery compartment to your desired channel. For the first
remote you may select any channel, for additional remotes select any unused channel;
3. Insert (2) AAA batteries according to the polarity markings. Replace the battery compartment cover .
4. Open the battery compartment at the back of the base station and insert (2) AAA batteries according to the
polarity markings. Replace the compartment door;
5. Press the °F /°C button at the back of the base station to display the temperature in °F or °C.
Note:
Do not mix old and new batteries.
Do not mix alkaline, standard (carbon zinc), or rechargeable (nickel cadmium) batteries.
For maximum performance in normal conditions we recommend using good quality alkaline batteries.
If the battery power is low, there will be low battery icon showing on the base station display.
Synchronize Remote Sensors with The Base Station
Please note: each time the batteries (either base station or remote sensor) are replaced or base
station/remote sensor lost connection, make sure to follow the below synchronization process to pair
and re-connect the base station and remote senor:
1. Position the remote sensor near the base station;
2. Once the batteries are installed in the base station, the RF signal icon (located on the upper left of the
base station display) will flash for 3 minutes, indicating that the base station is in synchronization mode: it is
waiting for remote sensors to be registered.
3. If 3 minutes have passed after the batteries were installed in the base station and the RF signal Icon is
no longer flashing, press and hold the CHANNEL/SYNC button on the back of the base station for 3-4 seconds
until the RF signal icon is flashing again to set it back in synchronization mode;
4. Install the batteries in the remote sensor and wait for a moment or just press either the TX or RESET button
inside the remote sensor battery compartment, the remote sensor temperature/humidity will show on the base
station display which indicates the synchronization is complete.
5. If you have additional remote sensors, repeat the above steps to register the remote sensors (up to 3 remote
sensors can be registered with one base station);
6. If you have registered more than one sensor, press the CHANNEL/SYNC button on the base station to
select the remote channel you want displayed permanently on the base station. Press CHANNEL/SYNC button
until you observe a circular arrow on the base station LCD display under the channel number. The unit will then
auto-scroll, changing from channel to channel every 5 seconds.
Place the Base Station and Remote Sensor
1. The indoor base station (receiver) should always be placed in a well ventilated indoor area and located
away from vents, heating or cooling elements, direct sunlight, windows, doors, or any other openings.
2. The remote sensor (transmitter) can be placed on a flat surface indoor or outdoor. Make sure the sensor is
within the transmission distance from the base station and with minimal obstructions.
3. The base station and remote sensor can both be wall mounted
