Chapter 2: Hardware Installation 2-37
Summary
If there is a touch screen calibration issue during or after installation,
take the following actions in the order listed:
1.
Recalibrate.
2. If recalibration is unsuccessful after two attempts, then run the
Noise check to change the frequency.
3. If you are still unable to calibrate, change the touch screen glass.
4. The final step is to replace the Processor Board. If this corrects the
problem, then the old glass is probably OK to reuse.
Out-of-Box Failures
The RSG-Atlanta Customer Satisfaction Hotline will replace out-of-box
failed hard disks with identical, preloaded drives. Once a system is
successfully installed, all disk contents are the responsibility of the
customer. The customer is responsible for restoring operating system
software and/or customer-specific data onto replacement disks sent to
repair a failed or damaged disk in the field. NCR provides recovery
tools for the operating system and platform software.
