If the sensor display is blank, place under a lamp for 24-hours to charge. 

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 (or under a lamp). Complete a restart. 

 

It may be helpful to orient the Display 90 degrees towards the sensor for better 

reception.  

 

Try repositioning the sensor or the display for better reception. 

 

Inaccurate Outdoor Temperature Reading 

 

 

The outdoor transmitter reads the environment. When mounted in the home it 

will read inside temperature. 

 

When the transmitter reads high during the day but not at night it is a 

positioning

 problem. 

 

Side-by-side test: Bring the outdoor transmitter in the house and place it next 

to the clock for 2 hours.  

 

Compare indoor and outdoor temperature. The temperatures should be within 4 

degrees to be within tolerance.  See the section on 

accuracy

 for details. 

 

If the transmitter reads correctly when next to the clock then try a different 

location outside.  

 

Look for heat sources such as sunlight, door or window frames, or reflected 

heat. 

 

Intermittent Outdoor Temperature 

 

 

RF (radio frequency) communication may come and go occasionally. This can be 

normal in some environments (e.g. moister climates). If transmitter signal is 

lost, please wait 2-4 hours for the signal to reconnect on its own.  

 

Move the outdoor transmitter to a closer location. 

 

Freezer test: Confirm the clock is reading the correct outdoor transmitter. 

Place the transmitter in the freezer for an hour and watch the temperature drop 

on the clock. 

 

Indoor distance test: Please complete th

restart

 with transmitter and clock 

5-10 feet apart and inside to establish a strong connection.  

 

After 15 minutes if there is a reading in the outdoor temperature area, move the 

transmitter to another room with one wall between the transmitter and the 

clock. Observe to see if the Temperature remains on consistently for 1-hour.  

 

If the temperature remains on while in the house then it is likely a 

distance/resistance

 issue. Move the transmitter to different locations outside to 

find a location where the temperature reading will hold. 

 

Distance/Resistance

 can cause loss of transmitter signal.  

 

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 (or under a lamp). 

  

MIN/MAX Temperature readings 

 

This station will show the minimum and maximum temperatures from setup, until 

you reset the min/max temperatures or remove the batteries from the station.  If
