Query: Loses connection with remote temperature sensor

I have had this product for about 3 months, in that time I've had to reset the connection between the remote sensor and the unit 3 times. This is not an easy process, the sensor is outside (obviously). You have to take the batteries out of both the clock and the sensor, then put them back in (first the sensor then the clock). Takes me a good 20 minutes each time (and on one occasion I had to repeat the whole thing twice). Then after a week they lose contact again! It's a good-looking clock, but essentially worthless to me as a way to know the temperature outside.
