Chapter 3: Maintenance
Replacing RealPrice Hardware
Except for the ESL battery replacement described in this chapter, the
RealPrice System hardware does not require any preventive
maintenance. If there is a problem, trained NCR Customer Service
personnel or other trained personnel can use the diagnostics and
troubleshooting information in the RealPrice Utilities Guide (B005-0000-
1487) to analyze and isolate the problem.
RealPrice hardware is not field-repairable. If it is determined that a
CBS, antenna, power supply, or ESL is defective, use the procedures
described in this chapter to replace the unit with a new one. If
appropriate, contact your NCR representative for information on
where to send the defective unit for repair.
Important Information: After removing or replacing the CBS or a
transmit antenna, it is recommended that RF communications be re-
certified. It is also recommended that the change in the site
configuration be noted for support purposes. For more information,
contact your NCR representative and reference the following:
