I didn't get any of my stuff until I went in to be activated, we just put disposable batteries in the uhhhh disposable battery I don't know, thing. My clinic is a 2 processor clinic so I got 2 processors, one for a back up. I ordered a white one and a teal one. They screwed up my order. They sent 2 white processors so she'll send one back and I'll pick up the teal one when I go for my second mapping on the 31st. Also I have a small battery for the Aqua pack (and all the waterproof accessories that comes with) the battery thing that uses disposables plus 3 large rechargeable batteries (2 teal 1 white) I ordered medium batteries but they sent large. But screw it, I'll live. Then basically at least 2 backups of everything, cables and tmics, head pieces etc etc etc. they were running a special, automatically you get 2 accessory kits, I picked the backup kit and the Aqua kit but with the special you got a 3rd for free so I also got a compilot. She doesn't think I'll be able to use that fur a few months. Oh!! And a nice back pack, travel kit, the obviously the zephyr and charger. I may have forgotten something.
You can send back the batteries and they will replace them, even opened, since it was a mistake. Personally, I don't like the big batteries and use the smallest ones. They give me a day of use and they are much more comfortable.
The Compilot is a great way to do rehab, especially if you have hearing in your other ear. She has to activate that on your programs though. I don't know why she thinks you should wait to use it, especially if you are understanding speech already. The backpack is great. I use mine all the time!!
