SECTION 210

GENERAL

This chapter provides a comprehensive understanding

of how to properly install each component of the

Electra Mark11 Digital Telephone System. It is recommended this chapter be read in its entirety to familiarize yourself with its content. This will enable a faster, more productive installation and cut-over.

Power being supplied to the system should be applied as a final step prior to the system operational testing (as described in Chapter 5 of this manual).

The Electronic		Telephone	Units	(ETUsl	make
extensive	use	of CMOS technology.		STATIC
DISCHARGES		TO ANY	ETU	MUST	BE
AVOIDED.
