What is the maximum distance I can have the remote sensor from the display?
The maximum open-air distance is 25 meters in a straight line although you should take into account the environment, distance and interferences. Subtract 6 to 10 meters for an exterior wall or any other similar obstruction, in width or composition. Subtract 3 to 10 meters per interior wall or any obstruction that is similar in width or composition. (An obstruction would include anything that is between the line of sight like a roof, walls, floors, ceilings, trees, etc.) Also keep your units away from electronic appliances like TVs, microwaves, computers, refrigerators and speakers.
Does the remote transmitter have any trouble transmitting through specific materials?
Yes and No We have trouble maintaining a signal through metal siding, stucco walls and UV glass. You can get the remote sensor to transmit through these materials, but it will take a little bit of trial and error. Reset the weather station as mentioned above and change the angle that the remote transmits through the siding or glass until an outdoor temperature remains on the display for an extended period of time. Keep in mind that the signal from the remote must travel through some space (10 cm of air minimum) before reaching a wall or glass window.
Where can I mount the remote sensor?
In order to get an accurate reading and to prolong the life of your sensor we recommend that you have it in a sheltered area out of the sun and direct rain. Fog and Mist will not affect the sensor, but a soaking in water may. You can mount it outside under an eve of your house or any other suitable place that will keep it out of the sun and rain. Do not wrap the sensor in plastic or seal it in a plastic bag.

How can I get outdoor temperature or humidity to show on the display for the first time or after loss of information (i.e. power blackout)
Bring both units (station + transmitter) inside your house and have the units 1 to 2 meters apart with nothing inbetween them. 1. 2. 3. 4. 5. Remove the batteries from both units, display and remote sensor. Wait until the display is blank to clear all memory (we recommend one minute). Put the batteries back into the display. Taking care NOT to press any keys, reinstall the batteries into the remote sensor. Do not press any keys for at least 10 minutes after installing the batteries. (Let them establish a good connection. Pressing a button during this stage would be enough to stop the search for the sensor which is being now carried out by the station). 6. An outdoor temperature and humidity should be showing on your display. You can now put your outdoor sensor back outside.
How do I reset the MIN/MAX temperatures and humidity?
Press and hold the either the IN (In is for resetting the indoor temperatures and humidity) or the OUT (Out is for resetting the outdoor temperatures and humidity) key for about 4 seconds. The minimum and maximum values for temperature and humidity that appear then on the screen are the current ones.

Why the display of the temperature and/or humidity is different between the outdoor sensor and the station?
You may observe that the station and the remote sensor may show two different temperature and/or humidity values. This is perfectly normal for the sensor collects outdoor temperature/humidity data every 60 seconds while the station does every 5 minutes.
What do I do if my display is blank?
Check the polarity on your batteries to make sure they are installed according to the diagram in the battery compartment. Also make sure that you are using a quality alkaline battery. We advise against reloading batteries.
How do I change the way the date is displayed?
This weather station has only one display for the calendar (date/month)
Why is my time incorrect or not displaying at all?
1. This clock receives a DCF-77 signal from Frankfurt to set the clock to atomic time. Sometimes, due to poor atmospheric conditions or local interferences you will not be able to receive a signal immediately. The best way to get a signal is to put your clock in a window facing Frankfurt until you see the tower icon appear. If definitely you are not receiving the signal, wait one night, during the night time there are less atmospheric disturbances. 2. If your time is off by an increment of exactly 1 hour, 2 hours, or more change your TIME ZONE on zero not to have time zone on the atomic time (which is CET meaning Central European Time (Brussels, Paris, Rome, Berlin, Madrid. ). Change time zone on -1 for Great Britain and Portugal. Match any time zone when receiving DCF-77 signal. 3. For this weather station, the time zone goes from -12 hours up to +12 hours.
How do I manually set my time if I do not wish to use the DCF-77 function? How do I manually set other features of this station?
*** The most recent models of this station have the DCF-77 activation and deactivation function *** If your station is provided with this function, deactivate in the first time the DCF-77 signal reception, then proceed as follows:
1. 2. 3. 4. Press and hold the SET key for 5 seconds. On the second line of your screen will appear 12h or 24h. To toggle between these 2 modes, press the CH button. When you have your choice shown on the display, press and release the SET button once. The time zone will now be flashing. To change the time zone press and release the CH button. When the correct time zone is selected, press and release the SET button once. The hour will now be flashing: press and release the CH button until the correct hour is displayed. Check the AM/PM mode. NOTA: In the 12h display format, only PM (for the afternoon) is displayed, under the word TIME. In the morning (AM), this area will stay blank. When correct hour is displayed, press and release the SET button once. The minutes are now flashing. Press and release the CH button until correct value is shown, press and release the SET button once. The day of the week is now flashing.

To increase or decrease the contrast of the LCD display press and release the CH button. Press and release the SET button once.
What means when OFL instead of data is displayed?
OFL is displayed when in- or outdoor temperature or humidity data are out of range. NOTA: - indoor temperature measurement range : from 0 C to 60 C (* from -9.9 C to 59.9) - outdoor temperature measurement range : from -29.9 C to 59.9 C (* from -29.9 C to 69.9 C) - in- and outdoor humidity measurement range: from 19 to 95 % (* from 1 to 99 %) for stations manufactured between 1999 and 2003. (* Between brackets are ranges for 2004 stations provided with new Swiss high definition sensor). In the case of outdoor temperature and humidity OFL can also be displayed when any interference occurs. Correct data transmission is usually restored during the next data collection. If that is not the case, you should restart your station (see above).

Weather forecast icon

Weather forecast icon indicates improvement or degradation trend rather than immediate sun or rain as the icon shows.
Example: if current weather is cloudy and the icon of rain is displayed, this does not imply that the station is deficient because it is not raining. It simply means that the atmospheric pressure fell and that weather will be getting poor but not necessarily raining.
Once your station installed, it is recommended to ignore the forecast for the next 24 to 48 hours, in order to leave time to the station and to operate in constant condition and altitude. Each noticeable and important change of atmospheric pressure will result in a change of icon. In the climates subjected to abrupt weather changes (e.g. sunny to rainy weather) the station will operate more precisely than in a climate with small weather variations (e.g. almost always sunny). In addition, an estimated forecast precision is about 75%. The La Crosse Technology weather stations are the only ones being equipped with a pressure sensor which records pressure variations every 3 hours and which calculates, on a 12 hours average, and displays weather tendency

averages. Consequently, the La Crosse Technology weather stations are more sensitive and more precise than all other similar products.

Function keys

This station has 8 function keys: 4 are apparent (SET, IN, OUT and CH key), 4 others are placed in a closed compartment (AL1, AL2, DATE and SNZ key). To reach these 4 last keys, just open smoothly the protective cap in the front of the station. Take care not to damage the cap while opening.
Check the polarity on your batteries to make sure they are installed according to the diagrams in the battery compartment. Also make sure that you are using a new good quality alkaline battery. We advised against reloading batteries.
How can I consult and reset the MIN/MAX temperatures?
This Temperature station will display the daily maximum and minimum outdoor temperature. The daily minimum temperature record is reset automatically at 8:00 pm and the daily minimum temperature is reset automatically at 8:00 am for the maximum every day. Thats why you need to set time ( see hereafter) You can manually reset both maximum and minimum records : Press + button for 3 seconds
How do I manually set my time?
1. Press and hold the SET button for 3 seconds. 2. The hour will now be flashing: press and release the + button until correct hour is displayed. Press then and release the SET button once. 3. The minutes will now be flashing: Press and release the + button until the correct value is displayed. Press and release the SET button once.
OFL is displayed when in- or outdoor temperature data are out of range. NOTA: indoor temperature measurement range : from -29C to 70 C outdoor temperature measurement range : from 25 to 95%
You will generally have to re-start your station, i.e. remove the batteries, wait a few minutes (until complete clearing of the LCD) and re-insert them.
