Disabling the Touch Screen on Symbol VC5090 FLT Terminals

You can disable the touch screen a couple of ways:

Firstly you can use the user programeable keys (see Prduct Ref Guide) where you can assign a function to the P1/P2 keys. One function available is disable the touch screen.

Secondly you can disable via the registry. To do this you need to create a reg key that sets the power state of the touchscreen to off.
Best way to find the key you need to alter is do a dump of the registry (using regsave tool or symscript) and look for the device driver TCH1.
In this key you should see a power state option...if you set power state to 4 it will switch the touch screen off. Create the key in notepad and save with a .reg extension. Place in the application directory and the setting will merge every cold boot.....please note you will then need to disable the calibration in Welcome.exe otherwise you will never be able to get past that window.

Cold Boot issue on Symbol VC5090 FLT Terminals

You can manually change the power setting to stop this behavior. The best thing to do would be to create a .reg file out of the following keys....

[HKEY_CURRENT_USER\CONTROLPANEL\DEVICES\CDL1:]
"TIMEOUTWAKEUPFLAG" = DWORD:00000000
"POWERKEYWAKEUPFLAG" = DWORD:00000000
[HKEY_CURRENT_USER\CONTROLPANEL\DEVICES\CDL2:]
"TIMEOUTWAKEUPFLAG" = DWORD:00000000
"APIWAKEUPFLAG" = DWORD:00000000
"POWERKEYWAKEUPFLAG" = DWORD:00000000

...and then copy that reg file onto a terminals \Application directory.
Then make the terminal cold boot, which will merge these reg keys and the terminal should be set so that if you suspend using the power button, remove power and then replace power, press the power button again the terminal should resume where it left off.

Sorting out Motorola VC5090 terminals

There are several scenarios that can happen with the VC5090 terminal. I'll try to describe each one and the remedy...

(1) The terminal re-boots and displays the "crosshairs"
(A) You must align the touch screen using the crosshairs, if you don't perform this the screen won't know where your stylus is and you won't be able to use the touch screen.
Tap the screen with something pointed but not damaging at the point where the crosshairs are located. You have to do this five times, and , at the end you will be prompted to tap the screen anywhere in confirmation.
At this point a box will appear on the left of the screen with some icons in, double tap the EXIT icon, then on the desktop, double tap the Telnet CE icon.

(2) When I tap an icon, nothing happens.
(A) The likelihood is that the screen has lost it's calibration and doesn't know where you are tapping. While you think your tapping over the right icon, the terminal thinks your tapping elsewhere.
You need to get to the crosshairs screen as per (1) above. There are two ways to do this.
The fastest way is to press the P1 P3 and POWER keys and hold for a few seconds, release the power key first, followed by the other two.
This should "cold boot" the terminal and after a minute you'll get to the crosshairs, proceed as per (1) above.
OTHERWISE.... Press the CTRL and ESC keys together to pop-up the start menu. Use the up, down and right arrows to get to the "Settings", "Control Panel". Then use the arrow keys to navigate to the icon called "Stylus", then press ENTER.

Now press the TAB key once, the RIGHT arrow once, the TAB key again and ENTER... This will end up at the crosshairs screen. Proceed as (1) until you have confirmed your calibration, then you can tap the X in the top right corner of each window to return to the desktop and then find and double tap the TelnetCE icon.


(3) The terminal is locked in some way, or behaves erratically.
(A) Press the POWER and P2 keys, then release POWER followed by P2 to warm boot the terminal.
