							PART 3 MAINTENANCE AND TROUBLESHOOTING
INTRODUCTION
This section explains how to keep the BUSINESSCOM
PLUS System operating properly.
It also shows how to
prevent or minimize operating problems, avoid system
failures,and extend the time between service calls.
o TELEPHONE TROUBLESHOOTING
The Telephone Test Procedure serves as an aid to
troubleshooting,and the Troubleshooting Guide sug-
gests common causes of system malfunctions.
o SYSTEM TROUBLESHOOTING
explains in greater detail the procedures required
to determine and correct specific system problems.
o POWER SUPPLY FUSES
The Power Supply Fuses table shows the function and
corresponding indications of failure for each fuse in
the systems power supply.
Maintenance and Preventive Maintenance
All system 
 use long-life components that do not
require regular,
scheduled maintenance or cleaning,
but several preventive maintenance procedures will
help to keep the telephones and the system in good
working order:
o Do not install the system in an environment that
promotes accumulation of dust, carbon or metal
particles,harmful vapors or contaminants: such
an environment may shorten the life of these
components.
o Before disconnecting or connecting power supply to
KSU and before installing or removing 
 be sure
that the power is OFF.
o The system uses a non-rechargeable lithium battery
to support system memory.
Replace this battery after
three years of service or if system memory becomes
altered without cause.
WARNING: D O  NOT ATTEMPT TO RECHARGE THIS BATTERY.
PERSONAL INJURY MAY RESULT.

Verify that the telephone set is connected to the
correct modular jack.
Using a voltmeter,measure the voltages at station
jack as described in INSTALLING THE 
 AND
CHECKING THE WIRING.
Disconnect the telephone from its modular jack, and
temporarily connect directly to MDF block in the
equipment room.
Temporarily try a similar telephone in the modular
jack for the telephone.
Verify the proper installation of the telephones
such as the speakerphone PCB.
Using a voltmeter,individually verify each station
cable lead.
Verify that the telephone cabling used is two-pair
twisted station cable.
Move station cable runs away from AC power lines
and data or computer-equipment cabling by at least
several inches.
Use commercially-available in-line chokes and
filters to remedy Radio Frequency Interference.
(For a definition of Radio Frequency Interference,
see FCC and 
 Requirements in GENERAL
INFORMATION.)
Check that all key telephone sets are installed
on-premises,using cable runs that are not exposed
to environmental hazards.
Check that OPX telephones are installed with addi-
tional secondary protection, such as lightning
protectors,near the MDF.
