1 USB Client Port This port is used to transmit system data and fi le data (download,

device.

Important!
Always make sure to fi rst remove the Handheld Terminal from the USB Cradle
when switching the selector switch.
Allowing the power contacts become wet can cause an electric shock or fi re. In
addition, if the contacts become soiled, contact may be impaired resulting in
poor charging. For reasons of safety and maintaining charging battery pack(s)
in optimum condition, clean the power contacts by wiping with a dry cloth or
cotton swab after disconnecting the AC adaptor.
Never short out the power contacts of the USB Cradle. This can damage the
USB Cradle.
Do not subject the Handheld Terminal and USB Cradle to vibration or impact
during communication. This can cause communication to be interrupted.
When placing the DT-X30 into the cradle, make sure that it is seated properly and
that the power LED at the front of the USB Cradle is lit in green. Charging and
communication will not proceed properly if the Handheld Terminal is not seated
properly.
Always cap ports that are not being used. Using the USB Cradle while the ports
are uncapped can cause damage.
