you wish a 24-hour min/max reading, reset the min/max temperatures at the same 

time each day. 

  

VIEW MIN/MAX READINGS: 

Press and release the PLUS button to view outdoor MIN/MAX readings, then indoor 

MIN/MAX readings then return to the normal display. 

  

RESET MIN/MAX READINGS: 

 Press and hold the PLUS button for 5 seconds to reset both Indoor and Outdoor 

MIN/MAX readings to current temperature. 

 

Sensor Stop Mode 

 

 

Place the sensor into Stop mode: Hold your hand over the solar panel for 10  

 

seconds and gently key the reset. The sensor display will say STP then go blank. 

 

Activate the sensor at any time by gently keying the reset button. 

 

Outdoor Transmitter Fell and No Longer Works 

 

 

First charge the sensor under a lamp for 24-hours. Then, try the restart with the 

station. Often a sensor was just shocked and may reconnect with a proper 

restart. 

 

Mounting/Positioning Outdoor Transmitter 

 

 

Mount outdoor temperature transmitters vertically and under a bit of an 

overhang.  

 

Protect the outdoor transmitter from standing rain or snow, and from the 

overhead sun, which can cause it to read incorrectly. Generally, mounting under 

an eave or deck rail works well. 

 

Construct a small roof or box for the transmitter if you do not have an overhang. 

Please be sure the box is vented. 

 

The solar sensor charges best when mounted on the East side of the house so it 

can receive  

cool morning sun to stay charged. 

 

Mount at least 6 feet in the air for a strong signal. 

 

Outdoor transmitters are water resistant but not water proof.  

 

Avoid more than one wall between the transmitter and the Clock. 

 

Do not mount near electrical wires, transmitting antennas or other items that 

will 

interfere

 with the signal. 

 

RF (radio frequency) signals do not travel well through moisture or dirt. 

 

Place the outdoor transmitter and the Clock in the desired shaded locations, and 

wait approximately 1-hour before permanently mounting the transmitter to 

ensure that there is proper reception.  

 

Do not mount the transmitter on a metal fence. This significantly reduces the 

effective range. 

 

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).
