2.Install Batteries into Wireless Display Insert 2 new "AA", 1.5 volt ALKALINE batteries into the wireless display according to the polarity marked on the battery compartment. Make sure to do this within 2 minutes of performing the start up process for the TX61U-IT. (Diagram on page 3)

Once the batteries are properly installed in the wireless display, the unit will beep and all segments of its LCD will light up briefly. The indoor temp and the time (displayed as 12:00) will appear on the LCD. 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.

3.Wireless Temperature Reception

After the wireless display is powered up, it will start receiving data from the TX61U-IT sensor. If reception is successful, the outdoor temp will appear on the wireless display. If the outdoor temp does not display within 5 min, remove the batteries from the display and go back to Step 1 (make sure the batteries are fresh).

If this happens, press the reset button on the TX61U-IT sensor to wake it up. If the voltage is higher than 2.5V, the LCD will turn on again and resume the transmission of the wireless temperature signal.

If the voltage is lower than 2.5V, “LO” will appear on the LCD and the sensor will enter into "IDLE" mode. Move the sensor to a brightly lit area. In "IDLE" mode, the LCD turns off and the sensor charges up the internal rechargeable batteries automatically. When the battery voltage charges to 2.5V, the LCD will turn on and the transmission of signal will start again.
