RESTART DISTANCE: For best results please bring the outdoor sensor in the house and place 5 feet from the display unit.
REMOVE POWER: Remove batteries from the sensor. Next remove batteries (and/or a/c cord) from the display.
DISCHARGE ELECTRICITY: With the power source removed, press one of the buttons on the display at least 20 times to clear all stored power. Please do this even if the display is blank to remove any remaining power. Verify the display is blank.
UNPOWERED FOR 15 MINUTES: 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.
BATTERIES: Please be sure you are using fresh batteries tested to a minimum of 1.48, on a voltmeter that reads in numbers.
SENSOR FIRST: Place batteries into the outdoor sensor first. Make sure they are installed according to the polarity diagrams in the battery compartment.
DISPLAY NEXT: Install batteries (or a/c cord) into the display according to the diagram in the battery compartment.
CONNECTION: 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.

Alkaline batteries will not work below freezing in the outside temperature sensor. Buy Lithium batteries for the outside sensor unit alkaline are okay for the inside unit.
SOMETIMES WHEN METAL IS IN DIRECT SUNLIGHT IT WILL GIVE FALSE READING. MY OUTDOOR THERMOMETER IS METAL AND IT READS ABOUT 15 DEGREES HOTTER THEN IT IS. BECAUSE IT'S IN DIRECT SUNLIGHT.
You have to push some buttons to tell the MAIN unit to scan, then put battery into the REMOTE, set channel, and hit reset through a little hole. And the MAIN should see it.
I had the same problem, Since the outside temp wouldn't read, I figured it was the outside unit batteries. Went through half a dozen AAA batteries and wouldn't read. It was the indoor unit. Had the same bats I installed 3 years ago. DUH! Replaced the AAA, and all was well. When the inside batteries die out, it has just enough juice to read indoor temp, but not enought to sense exterior signal.
Sometimes the RF frequency from the outside transmitter loses contact with the clock's frequency ( it has happened to me only twice in 6 years ), and then the outside temp will not show. Simple solution to fix this is: Take down the outside transmitter and the internally mounted clock. Remove batteries from both. Wait about 10 mts. First install batteries in the transmitter, then after about 30 seconds, install batteries in the clock. In about 5 mts, you will find the clock showing the external temp like before.
