If music is to be part of the system, connect a music source to the common equipment music interface jack (phono
jack) provided for this purpose. The impedance of this input is approximately 600 ohms. Level adjustment of the
music source may be necessary. The system will not support background music at stations with bridged proprietary
and auxiliary devices connected. See Section 3.5.6 for more information.MusicInterface

2.6 Checking The System2.8. I Checking The Installation and Wiring
::
Verify that the common equipment is mounted properly and that all wiring is correct.Check all of the following
wiring carefully: the chassis ground wiring, the line port wiring, the station port wiring, the AC wiring, and any
accessory wiring.
Once the basic system is verified as operational, perform the class of service programming as described in Chapter 3.2.8.2 Checking the Wiring Resistance To Ground
With the system unpowered, check the DC resistance from each individual wire terminal to earth ground. When
Ohm-meter measurements show low 
DC resistance (under 1 Megaohm) disconnect the wire and correct the problem.2.8.3 Powering-Up The System
And Doing A General Check
Connect the AC power. Check the green light emitting diode (LED) system status indicator. Be sure that it is on
steady.If 
it is off or flashing, refer to Section 2.9, Isolating System Failures.2.8.4 Checking The DC Voltages of The Station Ports
Check the common equipment and telephone installation for proper operation by performing the following voltage
measurement.
Make the following voltage measurements at the station connector blocks under the following conditions:.
Bridging clips installed.
AC power connected to the common equipment.
All telephones on-hook
Measure the voltage across each voice pair and across each data pair (See Tables 2.2 and 2.3).The measured voltage
must be as follows:

							InstullutionIMIG-1122.8.5 Checking Battery
And Batterv Charuer DC Voltaaes
Correct voltage of battery charger circuit without the batteries connected is as follows: between + 13.6V DC
and 
+13.8V DC for the positive battery and between -13.6V DC and -13.8V DC for the negative battery
(contact Comdial if the voltage is higher or lower),
Nominal voltage of each of the batteries is 12V DC,
Each fully charged and disconnected battery should not exceed a voltage of 
13.1V DC. A completely
discharged battery may check as low as 
1OV DC,
When the battery backup is installed and the system is powered, check the following:
Each fully charged battery connected to the system should have a voltage of less than or equal to 
13.8V DC (if
the value is greater than 
13.8V DC, contact Comdial).
NOTE: The typical battery service check is every three months.
,2.8.6 Checking The Default Conditions
The system operating features are set to default conditions at initial power-up. ‘These conditions provide a b&c
operating system with a known set of parameters, and the system should be initially checked out with the default
conditions in place. At any time while the system is operating, default conditions can be reset from station
port 10 or 12. For more information, see Chapter 3, section 3.4.

2.9 Isolating System Failures2.9. I Checking The System Status Indicator
“, . ..-. . :
A green LED located on the common equipment cabinet near the music port is the system status indicator. men the
system has power, this indicator 
SOYS lit.If the indicator flashes after power-up, it is indicating a processor failure.
Unplug and reconnect the AC power to the power supply and observe the LED indication.If it still shows a flashing
indication, equipment replacement may be necessary.
2.9.2 Doing A Station Self Test
You can self test the multiline stations for proper operation using the following instructions:
1.Disconnect line cord at station base.
2.Press and hold the 1 button and reconnect line cord to station connector. Station will automatically perform self
test routine.
NOTE: Active calls to the adjacent port may be dropped when you do a self test.
3.Release the 1 button as soon as test begins. Sequence of test is as follows:l
LED Indicators will light in sequencel
LED Indicators will then turn offl
Ringer will sound
4.Replace any station that does not pass the self test.2.9.3 Checking Failure Indications
If erratic light indications or ring signals occur at a paired station, an open data pair at either station may be the
cause.A station with an erratic data line connection may work properly on a short loop but fail on a long loop.
Stations are paired for overload current protection (2.6.2). If a fault occurs that causes more than 
300 milliarnps of
current to-be drawn, the overload paired stations are disabled by circuit action. Disconnect the disabled stations and
reconnect them one at a time to isolate the faulty one.

							FCC InformationIMI661122.10 FCC Rules And Regulations
This electronic key system complies with Federal Communications Commission (FCC) Rules, Part 68. The FCC
registration label on the common equipment contains the FCC registration number, the ringer equivalence number,
the model number, and the serial number or production date of the system.
2. IO. INotification To Telephone CompanybpI
Unless a telephone-operating company provides and installs the system, the telephone operating company which
provides the lines must be notified before a connection is made to them. The lines (telephone numbers) involved,
the FCC registration number, and the ringer equivalence number must be provided to the telephone company.The
FCC registration number and the ringer equivalence number of this equipment are provided on the label attached to
the common equipment. The user/installer is required to notify the telephone company when final disconnection of
this equipment from the telephone company line occurs.e
2.10-Z Compatibility With Telephone Network
When necessary, the telephone operating company provides information on the maximum number of telephones or
ringers that can be connected to one line, as well as any other applicable technical information. The telephone
operating company can temporarily discontinue service and make changes which could affect the operation of this
equipment. They must, however, provide adequate notice, in writing, of any future equipment changes that would
make the system incompatible.2.10.3 Installation Requirements
Connection of the electronic key system to the telephone lines must be through a universal service order code
(USOC) outlet jack supplied by the telephone operating company. If the installation site does not have the proper
outlet, ask the telephone company business office to install one.The correct outlet jack for this system is either a
type 
RJ21X or type RJ14C.
2.10.4Party Lines And Coin Lines
Local telephone company regulations may not permit connections to party lines and coin lines by anyone except the
telephone operating company.
2.10.5 Troubleshooting
If a service problem occurs, first try to determine if the trouble is in the on-site system or in the telephone company
equipment. Disconnect all equipment not owned by the telephone company.
If this corrects the problem, the faulty equipment must not be reconnected to the telephone line until the problem has
been corrected. Any trouble that causes improper operation of the telephone network may require the telephone
company to discontinue service to the trouble site after they notify the user of the reason.
