My wife purchased a new ET-73 for my birthday in March and the few times that I have used it I can't get it to transmit unless I am in direct view of the transmitter...
Is anyone else have this trouble? The batteries are new so I can eliminate that problem.
It is very frustrating since I have been looking forward to having this thermometer for a while and now that I have it, it doesn't do me any good.
Thanks for any help.
