Shouldn't a 67i set to Expedition Mode remain there? After a recent startling loss of energy remaining in my 67i battery, I discovered that when the device receives an InReach message, it switches to full power mode and remains there until reset back into Expedition Mode. Is there a reason for that? I'm pretty sure the device was not designed to trick users into depleting their battery on a long expedition. I use the "Prompted" setting for Expedition Mode. This is especially troubling since the device (contrary to the manual's explanation of LED codes) shows the same single-flash code whether the device is in Expedition Mode or in full power mode.
