SYSTEM MAINTENANCE
Maintaining the Vertical DX-120 digital telephone system is a combination of customer database changes, facilities
and apparatus moves, adds and changes. These requirements are accomplished by practicing the techniques,
illustrations and step-by-step instructions listed in the previous sections of this manual.
Cleaning the Telephones
When properly installed, the Vertical DX-120 is relatively maintenance-free. However, as with most things, from
time to time the digital telephone instruments may become dirty or dusty and require cleaning. We recommend the
following be considered:
•
Use a clean, dry cotton (or other soft, absorbent) cloth to wipe the instrument clean.
•
Do NOT use cleaning chemicals
-
The use of chemicals to clean the telephone plastics is NOT recommended since some chemicals can
cause permanent damage to the telephone finish.
-
If deep soiling conditions exist, many specialized telephone cleaning solutions will provide satisfactory
results.
-
When trying any cleaner for the first time, apply the cleaner to a small sample area on the underside of
the instrument. If the expected results are achieved, proceed with cleaning the remainder of the
telephone.
TECHNICAL PROBLEM SOLUTIONS
The system trouble shooting procedures are a logical approach to fault identification, analysis, and correction. The
DX-120 may generate symptoms of problems that actually occur outside of the office environment.
Problems Not Related to System Issues
The following is a list of that may be common situations that are NOT the result of a system component or software
failure.
•
system restarts (from temporary AC power interruption)
•
fading (from the long distance carrier)
•
dropped calls (caused by internal users randomly pressing holding CO line buttons)
