Installation Precautions
The ETUs used in this system make extensive use of
CMOS technology that is very susceptible to static
electricity. Static discharge must be avoided when
handling ETUs. Always use the following precautions:
Wear a grounding strap anytime you handle the ETU.
Make all ETU DIP switch setting changes before
inserting it in the KSU. Ensure that Make Busy switch
is Off.
Carry ETU in a conductive polyethylene bag to
prevent static electricity damage.
