La Crosse Technology, Ltd. Page 2Batteries Half of all warranty issues can be resolved with fresh batteries of the appropriate voltage. We suggest name brand alkaline batteries for indoor displays such as temperature stations. Use batteries dated at least six years in advance of the current year. Batteries dated earlierthan six years from now may still work, but may be unstable in performance. Alkaline batteries manufactured this year will have an expiration date 10 years in the future.Battery technology has improved and batteries will maintain voltage longer in storage.However, the environment the batteries reside in for the 10 years can deplete the power. Good name brand batteries make less noise, which reduces the chance of RF (radiofrequency) interference from the battery compartment. A minimum voltage of 1.48V for eachbattery is necessary for proper performance. Outdoor Transmitters: Use Alkaline batteries (or Lithium for temperatures below - 20°F/-28.8°C) Temperature Station: Use alkaline batteries. Overpowered or underpowered batteries maycause loss of indoor readings, missing segments, dim display etc.Temperature Station Factory RestartFACTORY RESTART: RESTART DISTANCE: For best results please bring the outdoor transmitter in the houseand place 5-10 feet from the display unit. REMOVE POWER: Remove batteries from the transmitter and from the temperature station. DISCHARGE ELECTRICITY: With the power removed, press one of the buttons on thedisplay at least 20 times to clear all memory. Please do this even if the display is blank toremove any random electricity. Verify the display is blank. UNPOWERED FOR 15 MINUTES: Let the temperature station and transmitter rest withoutbatteries for 15 minutes. IMPORTANT: Failure to allow a temperature station to rest for 15 minutes can result infailure to connect with the outdoor transmitter or missing segments on the display.Note: The instruction manual describes a setup for a new unit that has not had time to buildup residual electricity. BATTERIES: Please be sure you are using fresh batteries testing to a minimum of 1.48, ona voltmeter that reads in numbers. TRANSMITTER: Place batteries into the outdoor transmitter first. Make sure batteries areinstalled according to the diagrams in the battery compartment. TEMPERATURE STATION: Install batteries into the temperature station according to thediagram in the battery compartment. CONNECTION: Allow the transmitter and display to remain 5 feet apart for 15 minutes toestablish a strong connection. Do not press buttons at this time. You should see a readingon the outdoor temperature area in the first minute. See the section on mounting and distance/resistance/interference for details on mountingthe outdoor transmitter.Outdoor Temperature TransmitterCompatible Outdoor Transmitters A TX38U-IT outdoor transmitter is compatible with this Temperature Station.Power Requirements 2-AAA batteries power the outdoor transmitter. We recommend alkaline batteries for the transmitter.
