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 residual electricity. • BATTERIES: Please be sure you are using fresh batteries testing to a minimum of1.48, on a voltmeter that reads in numbers. • SENSOR FIRST: Place batteries into the outdoor sensor first. Make sure they are installed according to the 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.
