My GW-9400 is now about 9 months old and I'm very happy with it.
But since a while, my Rangeman get sometimes no radio signal. Even a manual sync won't help... It shows L2 or even L3 and a few moments later it shows ?ERR?.
Most of the time this happens when I'm wake up and it is cloudy/raining outside. But that also happend when it was sunny later that day.
As far as I remember, when I bought the watch, it was way more raining those days and it still got L3 Signal.
Right in the moment it is cloudy but not raining (normal autumn day in Austria ) and it still shows Error when I try to sync it. (I'm at work so it also happens outside my house) It tried it two times: 1x it syncs until L3 and then error appears, second time it shows error right after one minute without the signal indicator appearing.
I wear my Casio 5 days a week day and night if that matters.
Is my watch maybe faulty?
