Same instructions came with my handhelds. So there's no way to keep it turned on using AC power it seems, more of a portable unit. How is the reception when travelling in a car? My handhelds have the weather channels, but they don't come in too clear in the car. Nothing as clear as my Midland 300 with the telescopic antenna located on the 2nd floor of my house.
While traveling over the weekend, the radio did sound the alarm for a "Flash Flood Warning" while sitting in the cup holder (fold down console in a Buick Le Sabre), I'm not sure how far I was from the transmitter, but I do know the radio had correctly switched to a new frequency (as it should do while in the "travel" mode). The audio was very clear and easy to hear over the road noise.
I only used it for the four hours it took us to arrive at our destination, so I'll have to check the battery life some time this week.
Yes. I would say it's best used as a portable unit - exactly what I needed.
