Give details about the clock. Is it mechanical or electronic?

They are advertised as 50 foot range, but the accuracy starts falling off past about 35 feet

can the battery be replaced. If so, how? open the cover on the back of the device. this is done by squeezing the cover of the battery sector slightly. then remove the old batteries and replace the new ones (I assume you have the AAA) and put the new ones in keeping with the polarity for the device to work properly and then close the battery compartment cover in reverse order

Battery compartment contains reset button. Press. Will need to re-enter time and date. https://www.acurite.com/kbase/weather-stations/02031RM_Weather_Station.html

Place your remote temperature sensor and the inside unit together for about an hour to see if they both read the same or if there is a large difference in the temperatures.Dashes on the outside temperature reading may indicate that the inside unit is not receiving a signal from the remote. Change the batteries on the remote or change the location of the inside and/or outside units so that they can receive a strong signal between each other.Your smartphone temperature may be coming from a location that is not near your home. They are often from a weather service. Where is your local temperature sensor located? Is it in the sun? Is it on the south side of the house, or another location where the sun or an air conditioner or other heat source may affect the accuracy of the reading? Try to locate your outside sensor in a shaded location with plenty of ventilation, and away from heat sources.

Do you have a setting for the power line frequency? Some devices get their timebase from the power line frequency and if your powerline is 60 Hz, but you have it set on 50 Hz, then it will speed it up because of the 10 extra cycles per second.

The sensor should flash briefly when you put in good batteries. Afterwards it should flash about every couple of minutes. If you have a voltmeter check the batteries are at least 1.3 volts (the voltage will drop when they get colder). Ideally they should be about 1.4-1.6 V. Try cleaning the battery compartment contacts and springs with a cotton bud and alcohol. If the contacts look rusted then use fine emery paper or scrape with a screwdriver to remove the rust and tarnish. Clean the ends of the batteries by rubbing with a tissue or cloth. When inserting new batteries twist them inside the battery housing to help make better contact. Another thing you might try is to use a screwdriver to very carefully stretch the springs in the battery compartment a little to allow better contact. (Warning do not pull the spring too hard so as not to damage it) If using new batteries does not help then the sensor may have a fault. If the led on the outdoor sensor is flashing but the indoor sensor does not pick up the signal you can try putting the indoor sensor closer to the outdoor sensor. Otherwise you may need to re-tune the indoor sensor to the correct frequency (there is a small adjustable screw inside).

Hold the CLK button, and then the ADJ button. https://fccid.io/OWF-WSRX/Users-Manual/Users-Manual-171217

Radio Frequency communication may come and go occasionally. This can be normal in some environments (e.g. moister climates). If transmitter signal is lost, please wait 2-4 hours for the signal to reconnect on its own.

Hi Bogdan. i think the LCD is not good. if it is possible to replace it??? regards. nuwan

try new test leads first. even if the unit is miscalibrated, you should get the same measurements from the same components/circuits. you'll need to send the unit to a calibration center, or the manufacturer, to get it zeroed out, if you still need to afrer getting new test leads
