MOS CIRCUIT BOARD HANDLING PRECAUTIONS
The display terminal circuit boards contain a number of MOS
(metal oxide semiconductor) integrated circuits. The MOS
circuits are susceptible to irreparable damage if they are
exposed to excessive static electricity and thus require special
handling. Follow the precautions listed here at all times when
handling these boards.
• Never insert, remove, or otherwise connect/disconnect any
circuit(s) while power is applied.
