Introduction
Preventive Maintenance
Preventive maintenance requires no access to the
interior of the instrument and may be performed by the
user.
For VIASYS Neurocare systems, preventive
maintenance consists of:
• Scheduled file backup and hard drive maintenance
procedures, as described in Chapter 5: Routine
Backup and Maintenance Procedures.
• Periodically cleaning and inspecting the exterior of
the instrument.
It is recommended that you develop a schedule for these
purposes.
Inspecting the System
Routinely check the system for secure cable connections
and any sign of exterior damage.
Cleaning the System
Turn OFF the system power before cleaning the
instrument. Do not permit solutions or sterilization
agents to seep into the electronic portions of the system.
Take special care around controls, connectors and panel
edges. Do not use any abrasive cleaners.
Remove any dust from the exterior of the system with a
soft brush or cloth. Use a brush to dislodge any dirt on
or around the connectors and panel edges. Remove
stubborn dirt with a soft cloth slightly dampened with a
mild detergent solution or cold sterilization agent.
When the monitor is on, the screen has a slight static
charge, which attracts dust. To remove any dust
accumulation, wipe the screen with a soft brush or lint-
free cloth. You may use an antistatic spray on the screen
to reduce static buildup.
Service
If the system is not functioning properly, do not operate
it until all necessary repairs are made and unit is tested
for proper functioning in accordance with VIASYS
Neurocare published specifications. It is recommended
that all repairs be performed by a qualified service
representative only.
Periodically check the system ground integrity, the
system leakage current and the leakage current of the
amplifier.
