7. Plant personnel frequently use hand-held radios ("walkie-talkies"), or citizens-band
radios mounted in maintenance vehicles, for communications. To avoid RFI problems,
review the following:
• If radio communications must take place within an operating area or process
controller area, a base-station transceiver with an external antenna should be
used.
• For other applications, radio transmitters with outputs rated as high as 5 watts
must be kept at least 3 meters (10 ft.) from the Enhanced Micro TDC 3000
equipment during operation. Transmitters with outputs higher than 5 watts
must be kept as far as possible from your equipment. Keep equipment doors
closed while operating.
Other sources of RFI include generators, arcing relays, or motor contacts, etc.
8. Follow proper cleaning procedures when cleaning the operator area or the control room:
• Do not use water freely. Mop should be only dampened, not wet or dry.
• Use a lint-free, antistatic-type dust cloth to remove dust.
• Do not sweep around areas containing cartridge disks or drives.
• Use a vacuum cleaner on carpets—preferably one connected to an external
system.
• Do not allow liquids to be placed on the Enhanced Micro TDC 3000 keyboards
and equipment. Liquid spills will damage electronic components.
9. Clean the cartridge disk drive as outlined in the Universal Station Service manual in the
LCN Service - 1 binder to prevent errors and loss of data when loading programs.
10. Regularly clean the CRT face to minimize operator fatigue. Cleaning procedures are
found in Universal Station Service manual in the LCN Service - 1 binder.
11. Clean the printer before startup and periodically thereafter, as described in the
Universal Station Service manual in the LCN Service - 1 binder.
12. Periodically clean the operator and engineer keyboards by dampening a cloth with mild
detergent and wiping the keys. Do not spray detergent solution on the keys as moisture
may ruin the circuits underneath.
13. Periodically check and clean or replace the air filters in each cabinet. Refer to
subsection 6.3.1 of this manual for filter removal and cleaning procedures.
