Just got the GMC-320+ and went through the manual. There are some issues I can't handle with. I dont need a super accurate device, it's more for curiosity while geocaching/urban exploring.
A) The power-saving method is nice. The motion-detection too. The manual says, if the motion-detection is ON, it wont wake up the device.
A1) It would be nice to have the device at the belt during roaming around and get it out of power-save by alarm/push a button/double tab for a check (I think, thats the idea).
A2) Unfortunately the device wake up by every little movement. And there is no 'ON' in motion detection; just 'OFF', 'On Backlight' and 'On Backlight & DisplayMode'. Whats the difference? Can't get it out...
A3) Is there a way to wake the device up from power-save mode by pressing a button, without changing the display (just wake-up; not use the button as a function button)?
B) The temperature display. Is there any way to gauge that thing? There are never ever 28░C in my office. Two other sources show 15.0░; GMC means 27.8░.
C) How is the gyroscope to use? Is that in a way of factor times a hexadecimal value!? Just see for x, y and z a value like '0xFFE3'. Even when i put it steady on the table it seams to wobbling constantly around...
That's it in the first place. Beside that issues, it's a nice device... will test it by time. Seems to respond on the schist tiles in the floor by +0.08 ÁSv/h... funny.
