System Programming
It is very important to load default customer data when a system is first installed,
when upgrading software feature packages or when severe power disturbances
cause reason to doubt the customer database integrity. If any of these conditions
exist, please use the
Power Up Initialization
information in
Chapters 2 and 3, DHS and
DHS-E Description and Installation
, before proceeding with any customer specific
programming.
Customer Database programming is protected from loss during power interruptions by an
internal Nicad or Nimh battery. This battery will maintain customer database
programming for up to 300 hours when fully charged. For a battery to become fully
charged, the system must be powered continuously for 14 hours.
