3.3 Maintenance Utilities
The DX-80 includes a versatile maintenance utility that you access through PC-DBA. A technician
with PC skills can easily use the maintenance function to obtain various data and information about the
DX-80 and all connected components.
The DX-80 system allows you to administer system database parameters via an IBM
®
Compatible,
Personal Computer. The use of a PC has distinct advantages over programming the system via the
digital telephone, including: specific database archiving (via save function), remote programming, out
-
board programming (program the system template into the PC memory then send it to the DX-80 when
ready). The PC program that interfaces with the DX-80 system is PC-DBA (PC-Database Adminis
-
tration). Note: PC-DBA is a DOS-based programming utility.
PC-DBA requires the following resources in the PC environment:
• PC running DOS (PC-DBA can be run in a DOS Window but performance can be impacted by
other Windows
®
modules. We do not warranty or guarantee any level of performance in the
Windows environment.)
• 640k minimum RAM
• 386 minimum microprocessor
• 2 megabytes minimum space on the hard disk

When using PC-DBA to make customer
database changes you must take special
precaution not to overwrite existing data with
residual PC-DBA working directory values.
When using PC-DBA to update any database,
it is highly recommended to perform the
function Receive All prior to making any
specific database changes to assure that the
working directory database matches the
database in use at the customer site.
Bad Memory
battery
If power fluctuations occur and the memory
battery backup battery is low or bad, the
customer database is susceptible to being
defaulted (factory settings loaded) whenever a
power interruption occurs. If this occurs
change the standard (photo-cell type) lithium
battery.
