Thanks for the answers. Now I start to see what should I do,
but still would like to check with you if this is OK.

According to the manual, if I switch to low output power mode (it
has two modes) the maximum output power is 0.5 watt. This should
mean, according to my understanding, that if I use it only in low-
power mode and only on the FRS channels I should be fine.

So, I plan instead of returning the radios to the shop, to go on
using them with those limitations. I still prefer to have the
high power option, in case of real emergency, that's why I prefer
not to switch to FRS-only radio. Also, I would like to start
listening from time to time on the GMRS channels (no transmitting),
just to see how are the things there and decide if I would like to
get GMRS license or not (I probably would).

Is this OK?

Thanks,
