I was wondering if it was safe to remove the cover on a Monterra device. Just in case it ruins the seal on it or causes other problems. Just to clarify I am not talking about the D-Ring battery cover. I am talking about getting into the innards of the actual circuitry. Also, one more question. Is the Memory ([B]RAM[/B]) modifiable in this device? If anybody could answer my question that would be nice. Thanks in advance!
