Hi there!

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.

Thank you for your feedback.

For your questions:

A: there is a new version user guide should correct that tyo.

A1: The belt will be a good idea. The unit currently can wake up from sleep if yoy press one key.

A2: This feature is used to change the backlight or display mode by the motion event. Example tap the device. Also, this feature can be turned off by select OFF.

A3: The current firmware should already work this way.

B: You may need to way for longer time for the environment temperature.

C: Currently the gyroscope data only to show how the unit position in Hex value.
