Device Locked or Touchscreen Disabled
Make sure the touchscreen is not disabled or locked. On rare occasions, the operating system may state that the
touchscreen is currently enabled when it is not. Follow the instructions below.
Surveyor 2: Press the Blue shift and then Back Space (back arrow) key, repeat as necessary- Press and hold Power
button until menu appears, then use down arrow and Return keys to select "Enable TS" or "Disable TS", repeat as
necessary
Mini 2:Press the Shift (up arrow) + Backspace (back arrow) hardware keys- Press and hold Power button until menu
appears, then use down arrow and Return keys to select "Enable TS" or "Disable TS", repeat as necessary
Reset the Device
Perform a (Soft or Warm) Reset by pressing and holding the Power (On/Off) button for 5-10 seconds until the screen
flashes off briefly and the device resets.
Perform a Hard Reset by pressing and holding the Power (On/Off) button for a full 20 seconds. The screen and LEDs may
flash a few times during this time, but continue to hold until the full amount of time has elapsed.
Clean Touchscreen
Make sure nothing conductive is adhered to or stuck under the side lip around the touchscreen. After disabling the
touchscreen (as explained above) for cleaning the touchscreen and blowing (or washing and drying) out under the side
lip, you may need to both re-enable the touchscreen and perform a soft Reset (also explained above).
Switch Touch Profiles
If possible, you can use the hardware keypad or keyboard; an attached USB keyboard or mouse; or a remote display control
connection (such as MyMobiler) to navigate to Start > Settings > System > Touch to highlight a different Mode (profile)
and select the Load button. If loading another profile resolves the issue, if desired you may be able to switch back to
the original profile.
Reload or Update Touchscreen Firmware
Using direct install files to update the operating system or to specifically just reload/update the touchscreen firmware
may resolve the issue. Direct install files for just reloading/updating the touchscreen firmware are provided at the
following links.
Surveyor2-Touch-Reload.zip
Mini2-Touch-Reload.zip
Extract the ZIP file, copy the extracted files to the handheld (root directory or inserted MicroSD), connect wall
charger, and then soft Reset (hold Power button for 5 seconds).
Remove Power and Restore System
Removing the battery and wall charger for a few minutes will allow all hardware to reset. This may reset the touchscreen
hardware (if performing a Hard Reset did not already).
