What is the maximum distance I can have the remote sensor from the displays ?
The maximum open-air distance is 100 metres in a straight line although you should take into account the environment, distance and interferences. Subtract 6 to 10 metres for an exterior wall or any other similar obstruction, in width or composition. Subtract 3 to 10 metres 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 stations as mentioned hereunder and change the angle that the remote transmits through the siding or glass until an outdoor temperature remains on the displays 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 to show on the display for the first time or after loss of information (i.e. power blackout)
Bring all units (stations + transmitter) inside your house and have the units 1 to 2 meters apart with nothing inbetween them. 1. 2. 3. 4. Remove the batteries from all units, displays and remote sensor. Wait until the displays are blank to clear all memory (we recommend one minute). Put the batteries back into the transmitter. Taking care NOT to press any keys, reinstall the batteries into base stations.
Be careful, batteries must be inserted as mentionned hereabove (transmitter first, then in the base stations) to ensure a good functioning.
5. 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 should be showing on your display. You can now put your outdoor sensor back outside.
Note : By combining the 2 temperature stations WS 9750 and WS 9850, it is possible to have up to 6 outdoor transmitters (addition of 5 transmitters as an option).
How can I read and reset the MIN/MAX temperatures?
This Temperature stations will display the daily maximum and minimum outdoor temperature for each outdoor channel, at the bottom of the LCD, in normal display. To view the daily max and min temperature of another channel, you shall press the SET/CH key in normal display. The daily minimum temperature record is reset automatically at 8:00 pm and the daily maximum temperature is reset automatically at 8:00 am every day.
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 advised against reloading batteries.
How do I manually set my time, How do I manually set other features of theese stations?
1. Press and hold the SET button for 3 seconds. 2. Degrees Celsius will be flashing. To toggle between Celsius and Fahrenheit, press and release the + button. When you have your choice shown on the display, press and release the SET button once. 3. 12h or 24h will now appear. To toggle between 12h and 24h, press and release the OUT/+ button. Press then and release the SET button once. 4. The hour will now be flashing: press and release the + button until correct hour is displayed. 5. The minutes will now be flashing. Press and release the + button until the correct value is displayed. Press and release the SET button once.

What means when OFL instead of data is displayed?
OFL is displayed when in- or outdoor temperature data are out of range. NOTA: - indoor temperature measurement range : from -9.9 C to 59.9 - outdoor temperature measurement range : from -39.9 C to 59.9 C In the case of outdoor temperature, 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).
