It is important with most of our displays to remain without power for at least 

15 minutes.  

 

Note: Failure to allow a display to rest for 15 minutes can result in failure to 

connect with the outdoor sensor or missing segment on the display. The 

instruction manual describes a setup for a new unit that has not had time to 

build up stored power. 

 

GENTLY PUSH the RESET button on the TX62U-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 followed by the battery voltage will 

be shown on the LCD then the current temperature. 

 

Note: Voltage needs to be higher than 2.5V to maintain normal operation. If 

the voltage is below 2.5V, place the TX62U-IT in a window in the full sun for 

a day or two. 

 

DISPLAY NEXT: 

 

Note: Start with the Battery Switch in the Battery position.   

  

 

*RECHARGEABLE ALKALINE BATTERY (charged by solar panel): Install 

Alkaline Rechargeable battery. Move battery switch to the right. 

 

Allow the sensor and display to remain 5 feet apart for 15 minutes to 

establish a strong connection. Do not press buttons at this time. You should 

see a reading on the outdoor temperature area in the first minute. 

 

OR 

 

*PLAIN ALKALINE BATTERY:  

 

Please be sure you are using fresh batteries tested to a minimum of 1.48, on 

a voltmeter that reads in numbers.  

 

Install batteries into the display according to the diagram in the battery 

compartment.  Leave switch to the left. 

 

Allow the sensor and display to remain 5 feet apart for 15 minutes to 

establish a strong connection. Do not press buttons at this time. You should 

see a reading on the outdoor temperature area in the first minute. 

 

Outdoor Temperature Transmitter 

 

Compatible Outdoor Transmitters 

 

The TX62U-IT and the TX62UTH-IT sensors (915MHz) are compatible with this 

station. 

 

Fahrenheit/Celsius 

 

 

This clock reads in Fahrenheit only. 

 

Dashes shown for Outdoor Temperature 

 

 

Dashes means the connection is lost between the clock and the outdoor 

transmitter.   

 

Distance/Resistance can cause loss of sensor signal. If possible avoid more than 

1 wall, window, tree etc., between the display and the sensor. UV coated 

windows may actually reflect the signal. Stucco walls will absorb the signal.
