Troubleshooting

Problem

Action

The terminal will not 
start.

Make sure that the terminal is connected to a power 
source. If the external power cable has come unplugged, 
plug it back in and press the ON/OFF key to restart the ter-
minal. 
If the internal battery was charged, the terminal will main-
tain your session until you reconnect it to the power source 
and restart it. If the internal battery was not fully charged, 
you may have lost any unsaved data.

If the terminal is connected to a vehicle battery as a power 
source, check the vehicle battery. If it is depleted (dead), 
replace the vehicle battery.

The start-up process 
fails.

The terminal may be out of range of the Access Point (AP) 
and unable to communicate with the host computer. Move 
closer to the AP.

If either of these messages appears, contact your System 
Administrator:

Boot server doesn’t exist. 

Boot server not configured for this 

terminal.

Application does not 
respond.

The terminal may not be connecting to the Access Point 
(AP). Applications function until they need to transmit to 
the AP, then they stop responding. Contact your System 
Administrator.

Scanner laser works 
but does not read bar 
codes.

The bar code on the label may not be clearly printed. Try 
scanning another label of the same product, or type in the 
bar code data manually.

The scanner window may be dirty. Clean it with a soft, dry 
cloth moistened with an ammonia-based glass cleaner.

Scanner does not 
operate.

Make sure the scanner is properly connected to the termi-
nal’s Scanner Connector. Then restart the terminal with the 
scanner connected.
