I have a P20 back purchased about 2 years ago. Almost since day one, I have been getting error messages (one is 7227) and dialogs on the H1 screen such as, "Detach Magazine", "Attach Magazine", "Lens error", "System error" . . . the list goes on and on.
As Paul Schefz comments, many people have experienced these issues with the H1. You are not alone. It might be tough to put your finger on the exact issue.
* Capture Integration in Atlanta sells a tiny cable for the "older backs" that deals with power issues. It plugs into the FW port of the back. I would recommend calling them and buying that cable. Sorry, do not know what it's called, officially. It makes sure that the back has enough power.
http://www.captureintegration.com, ask for Tim Palmer.
* My P25 had the same issues. The newer backs have been changed slightly to avoid this issue, ie, P30, P21.
* Honestly, my opinion is that all these issues surround the H1 body, not the Phase backs. I sold all H1 gear and have never looked back. I got all of those error messages, and only at the most inopportune times. The H1 plots against you, and waits for the perfect light, before it fails. Since switching to Contax, those error messages are a thing of the past. I'm not telling you to switch, but I am reporting real-world history. It is Victor Hasselblad himself, orchestrating these error messages, from the grave -- still pissed off that they switched to 645 shape.
* In the POWER section of your Phase menu, check your setting, either AutoDetect, or Battery, or FW. That will also bite you, if the Powerbook's power drops below 50%, if you're on location.
* There are many variables to track this down. I'd talk to Capture Integration; very helpful and knowledgeable, and then, when you upgrade, do it with them. Sometimes you need a dealer with knowledge and availability. Phase One support, as a company is, shall we say, less than stellar. You need a solid dealer with real-world experience.
* Is that your real name? Sounds like a "film star" name.
