This unit uses a microprocessor control system. Do not short or jumper between
terminations on circuit boards or modules; control or board failure may result.
Be aware of electrostatic discharge (static electricity) when handling or making
contact with circuit boards or module connections. Always touch a chassis
(grounded) part to dissipate body electrostatic charge before working inside
control center.
Use extreme care when handling tools near boards and when connecting or dis-
connecting terminal plugs. Circuit boards can easily be damaged. Always hold
boards by the edges and avoid touching components and connections.
This equipment uses, and can radiate, radio frequency energy. If not installed
and used in accordance with the instruction manual, it may cause interference to
radio communications. It has been tested and found to comply with the limits for
a Class A computing device pursuant to Subpart J of Part 15 of FCC Rules,
which are designed to provide reasonable protection against such interference
when operated in a commercial environment. Operation of this equipment in a
residential area is likely to cause interference, in which case the user, at his own
expense, will be required to take whatever measures may be required to correct
the interference.
Always store and transport replacement or defective boards in anti-static ship-
ping bag.
