Enhanced 911 Configuration
The exclamation point within an equilateral triangle is intended
to alert the user to the presence of important operating and
maintenance (servicing) instructions in the literature
accompanying the product.
CAUTION: Only qualified persons should service the
system.
The installation and service of this hardware is to be
performed only by service personnel having
appropriate training and experience necessary to be
aware of hazards to which they are exposed in
performing a task and of measures to minimize the
danger to themselves or other persons.
Electrical shock hazards from the telecommunication
network and AC mains are possible with this
equipment. To minimize risk to service personnel and
users, the system must be connected to an outlet with
a third-wire ground. Service personnel must be alert to
the possibility of high leakage currents becoming
available on metal system surfaces during power line
fault events near network lines. These leakage currents
normally safely flow to Protective Earth ground via the
power cord. Therefore, it is mandatory that connection
to an earthed outlet is performed first and removed last
when cabling to the unit. Specifically, operations
requiring the unit to be powered down must have the
network connections (central office lines) removed first.
CAUTION: Warning
Local, state and federal requirements for Emergency
911 services support by Customer Premises
Equipment vary. Consult your telecommunication
service provider regarding compliance with applicable
laws and regulations.
