Maintenance and Troubleshooting
Solution
Temporarily disable the radio link to force
data transmission through the cradle. Tap
the wireless LAN icon from the systray on
the Today screen.
Tap the Mode/General tab. Enter an in-valid
value in the ESSID: text box and tap the OK
button. Power cycle the terminal. Verify that
your radio link has been disabled (the
wireless LAN icon has a red box with a ! on
it).
Once you have completed your data
transmission, re-enable your radio link.
Connect the unit to an Ethernet network
with a correctly functioning DHCP server.
Connect a properly configured DHCP
server or DHCP relay agent to the subnet,
and power cycle the cradle. Check the
DHCP server log to verify that the cradle is
receiving a response to its DHCP request.
Ensure the ethernet cable is connected to
an active hub.
Remove power supply input A/C voltage for
30 seconds, then reapply power to
establish proper power supply output
voltage.
Check power supply using different cradle
and power outlet.
Remove, wait a minute, and then reinsert
the terminal, ensuring it fits snugly onto the
connector at the bottom of the cradle.
Ensure the power supply is securely
connected and receiving power.
