Yes it is stated as JIS4 on the Sangean site. The JIS4 Standard is not really a Water-Proof standard, but rather water-resistant. JIS4 in a nutshell means the product must be able to work without damage after submersion in water up to 1 metre for 30 minutes. In other words, it is for products where expected use around water is not under high-pressure, but it could get wet and still be ok. Typical for products with intended use around pools, marine craft, or weather/rain use. Not intended for taking diving for example.

Q: Will it work in a heavily insulated aluminum siding with shop florescent lighting?

I have one in my large barn w/ florescent lighting, and it works better than the radio that was in there. I don't see where insulation would interfere with reception.

Q: Help an old geezer out here...what is the purpose of being able to plug in an iphone? Just charging it?

Just to output the audio into the radio so it is louder. You cannot charge the iPhone with the radio.

Q: how good is this radio dependable good reception strong

hi catie , love this thing to death , the re-charge batteries are great , it runs for no less than 12 hrs at work , it has a very high volume output , my only gripe is the reception, it can be terrible at time`s , I have no idea why , but being digital , you can not simply turn the dial to make it come in better , but it does have the ability to use your phone or what ever type of electronics you might have , I do not have any of that crap , just the AM - FM , but for the durability and coolness of the radio , it is worth every penny , just needs a bigger antenna from radio shack or something .
