Frequently Asked Questions - T80864 LA CROSSE TECHNOLOGY
How do I set up the T80864 thermometer?
To set up, insert 2 AA batteries into the main unit and 1 AA battery into the outdoor sensor. Place the sensor within 100 feet of the main unit. Wait for the signal to connect; the outdoor temperature will display within a few minutes.
How do I switch between Celsius and Fahrenheit?
Press and hold the °F/°C button on the main unit for 3 seconds to toggle between Fahrenheit and Celsius display.
What batteries does the T80864 require?
The main unit uses 2 x AA batteries, and the outdoor sensor uses 1 x AA battery. Use fresh 1.5V alkaline batteries for best performance.
Why is the outdoor sensor not receiving a signal?
Check that the sensor is within range (100 ft open air) and that both batteries are inserted correctly. Move the sensor closer and avoid large metal surfaces or electronic interference. Press and hold the TX button on the sensor for 2 seconds to resend a signal.
How do I reset the thermometer?
Remove all batteries from the main unit and the sensor, wait 30 seconds, then reinsert them. This clears all stored data and restores factory defaults.
How do I read the MIN/MAX temperature records?
Press the MIN/MAX button to cycle through the minimum and maximum recorded temperatures. Press and hold the button for 5 seconds to clear the records.
How far can the outdoor sensor be from the main unit?
The transmitter has a maximum range of 100 feet (30 meters) in open air. Actual range may be reduced by walls, windows, and other obstacles.
How do I clean the thermometer?
Use a soft, dry cloth to wipe the display and housing. Do not use any solvent or abrasive cleaner as it may damage the plastic finish.
Is the outdoor sensor waterproof?
The sensor is weather-resistant and designed for outdoor use, but do not submerge it in water. Protect it from direct rain or flooding.
What should I do if the display shows --- for outdoor temperature?
This indicates a loss of signal. Press and hold the TX button on the sensor to transmit a new signal. If the problem persists, replace the sensor battery and check the transmission path.
