Troubleshooting
Problem: T-RX™ will not power on.
Suggested Action: Does the battery have sufficient charge? Plug-in provided AC adapter. Try
powering your T-RX™. If the unit powers, keep the T-RX™ connected to external power until the battery
is fully charged. If the T-RX™ does not stay powered after charging is complete, the battery may need
to be replaced.
Problem: T--RX™ Does not indicate it is charging when the external AC adapter is plugged in.
Suggested Action: Verify light is on at AC adapter. If it is not lit, try another AC outlet. If the adapter
power light does not light contact CCX technologies to purchase a new AC adapter.
Problem: The touch screen indicates I am pressing on a different section of the screen other than
where I touch.
Suggested Action: Perform a screen calibration per the section above titled,
How to calibrate the
T-RX™ touchscreen.
