Tapping the window 
buttons or icons does 
not activate the 
corresponding feature.

Screen is not 
calibrated correctly.

Re-calibrate the screen. See Calibrating the Screen on page 1-8.

The system is not 
responding.

Warm boot the system. See Resetting the EDA on page 2-24.

A message appears 
stating that the EDA 
memory is full.

Too many files stored 
on the EDA.

Delete unused memos and records. If necessary, save these 
records on the host computer (or use an SD card for additional 
memory).

Too many 
applications installed 
on the EDA.

Remove user-installed applications on the EDA to recover memory. 
Select Start - Settings - System tab and tap the Remove Programs 
icon. Select the unused program and tap Remove.

EDA keeps powering 
down to protect 
memory contents.

The EDA’s battery is 
low. 

Recharge the battery.

The radio is powered 
on for a long time.

Because this mode requires battery power, power it off when not 
needed. Using the SetDeviceState() API (refer to the SMDK Help 
File), set the Bluetooth to D4 power state.

The EDA does not 
accept scan input.

Scanning application 
is not loaded.

Load a scanning application on the EDA. See the system 
administrator.

Unreadable bar 
code.

Ensure the symbol is not defaced.

Distance between 
exit window and bar 
code is incorrect.

Place the EDA within proper scanning range.

EDA is not 
programmed for the 
bar code.

Program the EDA to accept the type of bar code being scanned. 

EDA is not 
programmed to 
generate a beep.

If the EDA does not beep on a good decode, set the application to 
generate a beep on good decode.

Battery is low.

If the scanner stops emitting a laser beam upon a trigger press, 
check the battery level. When the battery is low, the scanner shuts 
off before the EDA low battery condition notification. 
Note: If the scanner is still not reading symbols, contact the 
distributor or Symbol Technologies.
