1) ActiveSync automatically is on when the device is on. Why? It destroys the battery life. Can it be set to come on manually?
On your home screen (TouchFlo) press & hold the "Menu" button in the extreme upper right corner. This will open an Icon Window: if ActiveSync is running it will appear with its own little icon + an "X" box that will turn it off.
Also, the "Wrench" icon opens the Task Manager which (among other things) shows a list of running programs & allows you to kill them (selectively, or all at once).
2) When the device is OFF, and a call is made to it, the device powers ON. That also drinks the battery juice. Can it be set to not ring when it is powered OFF?
Several thoughts:
1) Simply Pressing the power button does not actually turn the Fuze "OFF" - it merely puts it into a Sleep Mode, which kills the display but leaves the unit otherwise ready for work.
2) To actually turn the Fuze OFF, Press And HOLD the power button: you will get a warning that you will lose any unsaved data - it you hit "Yes" the Fuze will actually power completely down. Obviously you must now Press AND HOLD the Power button to turn it back on - which will take a bit of time; approximately similar to a soft-reset on a PPC (or, at least, on my Axim X30 Mid....

)
3) Pressing either Volume button (on the Left side of the Fuze) opens the Volume Application & presents you with On-Screen Touch Buttons that will instantly Silence the ringer or put the unit into Vibrate mode.
You can return the unit to Ring mode - AT your previously set volume - simply by Touching the darkened Volume Level Meter that appears above "Vibrate" icon.
Very Handy!
4) If you activate the Gyro function you can Silence the Ringer - and reject the incoming call - simply by turning the Fuze face down. (Phone Settings - "Advanced" allows you to set "Reject A Call With Text Message" - which is ON by Default, along with a Default "I am busy....." message. This setting also works if you select "Reject" when a call comes in.)
5) Tapping on the Signal Strength indicator (on the upper icon bar) - or the WiFi indicator if turne on, or the 3G/Edge icon - will open a dialog box that allows you to select either "Settings" for that service, OR the "Wireless Manager."
NOTE: With TouchFlo on, pressing one of these icons opens a completely redundant Status Screen that shows you what is running - simply press one of the Communication icons (WiFi, 3G or Antenna).
The Wireless Manager allows you to turn ON or OFF: Airplane Mode;
PHONE (!); Bluetooth, Wifi, MS Direct Push, and Data Connection.....
3) I cannot locate a case that protects the touchscreen---and remains practical with the screen showing so as to continally apprise me of all types of messages as they arrive. Even putting the device into my shirt pocket makes it turn a page. Betwixt the touchscreen and the PTT button, I am repeatedly hitting the HOME "button" to get back to where I want to be.
No help on case yet. Have seen some FLIP cases that fit the Fuze, and while these work well for PDA (PPC) functions - have 2 for my Axim, 1 Industrial and 1 Fancy Dress - they would not work for phone (although with Bluetooth activated....)
Sounds like you are putting the unit into your pocket with screen still Active. Instead, press the power button to turn screen off: again, this only puts unit to "Sleep" and it will retain whatever application(s) you had open.
Slighly different take on "protect the touchscreen": Have you applied the Screen Protector that came with the Fuze? Like most of these, the one for the Fuze can be a pain to apply - especially as they provide NO instructions whatsoever for it (unless included on CD??), but you can find these on line if you need.
Managed - FINALLY! - to get mine on well, and you would not even know the unit has it applied unless you look Very Carefully....
Am liking the Fuze more & more with continued usage....
