Step 1.
Wake Up TX61U-IT Sensor
To begin the set up process, use a paper clip
to GENTLY PUSH the reset button on the
TX61U-IT sensor. All LCD segments will light
up briefly. The code number and the security
code ("20" for example) of the model will be
displayed sequentially. Next, the battery
voltage will be shown on the LCD, it should be
higher than 2.5V to maintain normal operation.
Then the current temperature will appear on
the sensor's LCD and it will start to transmit the
wireless temperature signal.
Note:
When the voltage of the TX61U-IT
sensor is lower than 2.5V, the transmission of
signal stops and “LO” is displayed on the LCD
for approximately 2 seconds before the sensor
enters into the "IDLE" mode. In the "IDLE"
mode, the LCD turns off. The sensor will check
and charge up the internal rechargeable
battery automatically. When the battery voltage
rises up to 2.5V, the LCD will turn on and
transmission of signal will start again.
Step 2.
Install Batteries into Wireless Display
Insert 2 new "AA", LR6 1.5 volt ALKALINE
batteries into the Wireless Display according to
the polarity marked on the battery compartment
within 2 minutes of performing the start up
process for the TX61U-IT. (Diagram on page 7)
Once the batteries are properly installed in the
Wireless Display, the unit will beep and all
segments of its LCD will light up briefly. Then
the indoor temperature and the time (displayed
as 12:00) will appear on the LCD.
Page 4 of 14
If it does not appear after 30 seconds, please
reinstall the Wireless Display batteries and try
again. Once the indoor data is displayed,
proceed to the next step.
Step 3.
Wireless Temperature Reception
After the Wireless Display is powered up, it will
start receiving wireless temperature signal from
the TX61U-IT sensor. If reception is successful,
the outdoor temperature will appear on the
Wireless Display. If this does not happen after
5 minutes, please remove the batteries from
the Wireless Display, make sure the batteries
are fresh and go back to Step 1.
Step 4.
Distance Between Units
To ensure sufficient 915 MHz wireless
communication, the final distance between the
Wireless Display and the TX61U-IT sensor
should be no greater than 200 feet (60.96
meters) open air.
TX61U-IT Sensor Power Save "STOP" Mode
If the TX61U-IT sensor is placed in a dark
environment for 24 hours, it will enter into the
"STOP" mode to save power. The LCD will turn
off and it will stop transmitting the wireless
temperature signal. If this happens, please
press the reset button on the TX61U-IT sensor
to wake it up again. Afterwards, if the voltage is
higher than 2.5V, the LCD will turn on again
and resume the transmission of the wireless
temperature signal. However, if the voltage is
lower than 2.5V, “LO” will appear on the LCD
and the sensor will enter into "IDLE" mode.
If the battery voltage is lower than 2.5V, please
relocate the TX61U-IT sensor to a brighter
environment in order to charge up the internal
rechargeable batteries to continue normal
operation.
