MAINTENANCE PROCEDURES
a.
Preventive Maintenance
Use of preventive maintenance allows detection and correction of minor
faults before they become serious enough to cause equipment failure. As
a result, major repairs can be avoided, and the equipment can be
maintained in an operable condition with a minimum of maintenance.
Every 3 months, perform the following.
1.
Inspect all interface connecting cabling for deterioration or other
damage.
2.
Clean the enclosure with a soft cloth using any mild commercial
cleaner.
b.
Troubleshooting
If problems occur at the initial installation phase, they are probably due to
improper installation/set-up.
