My friend got this model (upon my recommendation). When it was installed in her home, a strange thing happened. The signal from the remote control of the pana is apparently the same as or close to the mitsubishi aircon she has in her house (the kind operated by remote control). So, whenever she touched anything in her pana remote (volume, switch channels etc), the aircon would respond with an annoying click. she had no choice but to buy another model/brand.
