Thanks for the reply. I will check out the MX-600-that would also give me remote capability without the need for line-of-sight connectivity. I like the functionality of the 3806 remote (except for the button display membrane, which is somewhat dim and hard to read when used outside), but I would like to have a second remote that I can take out to the patio while still have remote control capability in the main zone. The scenario that keeps popping up is: my wife is watching TV and needs to control the volume, channel, etc, while I am on the patio listening to an FM station or a CD. It would be really nice to be able to control the 2 zones simultaneously with 2 different remotes. I also heard about a remote called the Dolphin that is apparently made for use in spas and pools, and it has RF remote capability. I will be checking that one out as well, since it it designed specifically for outdoor use.
