Does the GSP 7 have a battery? If so, how do I go about replacing it?
I have a GSP 7 that I've recently brought out of retirement. It works fine, but I don't think it's recalling its state when I shut it down. For example, when I power it up, it looks like it resets and then selects patch 1. But not always.
I'm wondering if it has a battery, and if so, what kind and are there instructions on how to replace it available?
