Re: white vertical lines

The LVDS cable between the units mainboard and LCD is loose, or the LCD driver IC is on the way out. the only way to fix this is to reseat the cable or replace the mainboard

'tab' button doesn't work on Motorola MC3190

You get 3 different keypad models of the Motorola MC3190:
- 28 Key Numeric
- 38 Key Shifted Alpha
- 48 Key Alpha Numeric

So depending on the type of keyboard your model has, using TAB are different across these 3 keypads.

Please Note: Keypad functions can be changed by an application so the mobile computer keypad may not function as described.

When the FUNC button is pressed the icon "F" appears on the taskbar on WinCE devices or the icon "Blue Circle" appears at the bottom of the screen on Windows Mobile 6.1 devices.

In order to use the TAB function, do the following:

28 Key Numeric - Press the blue FUNC button (Bottom right next to Power button), and press the RIGHT ARROW button.

38 Key Shifted Alpha - Press the blue FUNC button (Right side below RIGHT ARROW button), and press the RIGHT ARROW button.

48 Key Alpha Numeric - Press the blue FUNC button (Right side below ENTER button) and press the number 9 button.

Cannot connect with the current connection settings. To change your connection settings tap settings.

I sometimes will wipe the device clean and install a new version of OS.. but you can call motorola directly and ask for a download link for the build number you want. 1.847.576.5000

this link should get you in the right spot.. but you want the Cleaner Device Software if you can find it..

load it to a micro/SD card, put it into the device. plug into power, hold 1 & 9 press power.. release all.. press power again and hold yellow laser trigger until it asks you to update loader.. this will reset your device.

we had to disable power save on ours cause the scanner sleeps and shuts off wifi, and took 1-2 minutes to reconnect to our wifi radios.. and the app would time out.. so I suggest doing the same.

I have two MC9090s where it will not go past the splash screen. It will notify me of whether I did warm boot, cold boot, or if the battery door is open, so it's not frozen at the screen. I've requested...

Press and hold the trigger while cold booting the device. THEN PUT STRAIGHT INTO A POWERED CRADLE (or the loading menu will not display)

If you really struggle contact to have the units repaired.

MC9190 WLAN Problem

To permanently disable the Suspend Mode on a MC9190:
On your PC, create an empty text file, then type the 2 following lines:
"BattSuspendTimeout" = dword:00000000

Save the file, then change the extension to ".reg". This changes the text file into a registry file.
Copy the registry file in the /Application folder of the scanner gun. Cold boot the device. Your MC9190 will no longer go to sleep mode, or "suspend mode".

To automatically enable the Wireless antenna at startup, create another registry file, then type the 2 following lines:
Save the file, and copy it into the /Application folder of the scanner gun. Cold boot the device.

How do you enable Wireless on MC9090

If there is an 'X' on the radio icon not a '!' then it has been disabled.

To switch it on hit the wireless icon in the taskbar and select [enable radio].

If the radio fails to switch on then try a warm boot:-

Hold down the power button for approximately 10 seconds until the splash screen is shown.

If it still fails proceed with a cold boot:-

Partially remove the battery, hold down the On/Off button, the trigger and reinsert the battery. When the orange light on the keyboard flashes release the on/off button and the trigger.

If the on/off button or trigger is held down longer than required this occasionally causes the terminal to get caught in a warm boot cycle

If the fault is still not rectified then the device requires repair. Which we can help with as we have a specialised repair centre.

If there is an '!' on the radio icon not a 'X' then the radio cannot associate to an AP due to regulatory issues.

Hit the wireless icon in the taskbar and select [options], a pop up is then display, select [Regulatory] from the pull down menu. Then select your country and switch of 802.11d if not required. Save and exit
