TECHNICAL ASSISTANCE AND REPAIR SERVICE 
Technical Assistance 
---_ .--.--.-- --.._ _ 
Shquld 
you experence difficulty with installation, checkout, or 
programming, and have made an attempt to isolate the problem using 
information provided herein; 
or 
should you encounter problems at a 
later date which cannot 
be resolved by referiny to this manual, call 
the Comdial Technical Service staff. 
800-431-4345 (in Virginia: They can 
be reached at 
800-654-3345) between the hours of 8:00 AM 
and 8:OO PM Eastern time, Monday through Friday. 
When calling for technical assistance, 
you should 
be at the job site 
and you should have in your possession, as a minimum, an accurate 
volt-ohm meter and a copy of this manual. 
Repair Service 
- -- .--.--.-.-v 
If your 
KSU or an individual station needs repair, subsequent to the 
warranty period, it may be returned to Comdial. Comdial will, at 
their option, 
either repair the defective equipment or replace it with 
a remanufactured unit. This repair will 
be done for a fixed charge. 
For information on this charge, 
please call or write to the address 
given 
below.

Attention: Repair Department 
Telephone: (804) 978-24Oa 
When returning equipment for repair, 
pack it carefully to prevent 
damage. Any damages during shipment will 
be the responsibility of the 
purchaser. 
The equipment should be shipped freight or postage 
prepaid. 
FUSI~ LOCATION 
The KSU is protected against short circuit damage 
by a fuse located in 
the primary of the AC transformer winding. Fuse FS-1 is a 2 amp, 
25OV, SLO-t3iXl type fuse. 
The fuse holder is located near the top of 
the right side of the KSU cabinet. Always replace this fuse with one 
of the 
same value and type, otherwise, 
equipment damage could result. 
FAILURE ISOLATION 
VJirinq 
-.- 
Refer to the installation check 
out procedure for inst>ructions for 
testing the 
system wiring for possible failure.

System gt_atus Indicator 
.- -- .- ---- ---- 
The red LED located near the fuse holder 
is the system status 
indicator. 
This indicator should turn on steady when AC power is 
applied to the 
KSU. If the indicator flashes after power up, it couid 
be indicating a processor failure. Unplug and reconnect the AC power 
to the 
KSU and observe the LED indication. If it still shows a 
flashing indication, refer to Figure 4-l. 
Station Self Test 
------ .---- --_ 
The multiline stations can be self tested for proper operation per the 
following instructions. 
1. Disconnect the line cord at the station base. 
IMPORTANT NOTE 
THE ADJACENT ODD OR EVEN STATION WILL BE DISABLED DURING THE 
TIME THAT THE STATION 
LINE CORD IS BtiING DISCONNECTIW OR 
HKONNEWED. 
2. Press and hold the tYUTE 
key I and reconnect the line cord to the 
station connector. The station will 
automatically perform a self 
test routine. Release the MUTE key as soon as the test begins. 
The sequence of the test is as follows:

DSS/BLF Console Self Test 
, Test the DSS/BLF Console for proper lamp operation per the following 
procedure. 
1. Disconnect the console line cord plug from the line. 
2. Press and hold console key Cl0 while reconnecting the line cord 
plug to the line. 
IMPORTANT NOTE 
THE COMPANION STATION WILL BE DISABLED DURING THE TIME 
THAT THE CONSOLE IS BEING DISCONNECTED AND RECONNECTED. 
3. Release console key ClO, and note that the BLF indicators will 
each turn on in sequence beginning with the station 10 indicator. 
The indicators will then turn off and the console will become 
operational. 
Paired Stations 
-- - 
Station ports 10, 11, 12, 
and 13 
ports 10, 11, are paired for data with 
12, and 13 adjunct 
respectively. Station ports 10 through 41 
are paired for data and for overload protection as shown in Table 3. 
Adjunct ports 10, 
11, 12, and 13 are not overload 
paired with any 
other port. 
If erratic light indications or ring signals occur at a paired 
station, an open data pair at either station may be the fault. A 
station with an open data line may work properly on a short loop but 
fail on a long loop. Test the wiring of stations showing this symptom 
per the checkout procedure given in Chapter 2. 
If a fault occurs which causes more than 300 ma. 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.

Failure Analysis 
- - --a 
KSU And Station 
Figure 4-l details a failure analysis flow chart to assist a service- 
technician in isolating a failure in a defective system. 
One way to 
isolate a failure is 
to substitute a known good assembly for a 
suspected one. This is the recommended failure isolation method to 
use with the system. 
Connecting and disconnecting stations to the 
system does not affect 
the stored station auto/speed dial memory data. 
This data is stored 
in the KSU memory and not at the individual stations. 
KSU, however, 
causes all stored memory to be lost. 
Replacing the 
This includes all 
memory dialing numbers as well as all COS programming data.

L)ESK/WALL REVERSAL AND WALL MOUNTING 
(22 Line/Feature Keyset and Single-Line Keyset, Only) 
Conversion 
To convert a station from a standard desk model to one which can be 
hung on the wall, follow the procedure outlined below. 
1. 
Remove and discard the pull out directory (22 Line/Feature Keyset, 
only). 
2. 
Remove the lower housing of the station, and rotate it 180 
degrees. 
w 
The PWB contains circuitry which is sensitive to static 
electricity discharge. 
Be sure that your body and the 
workplace are properly grounded to avoid any static 
electricity discharge while performing the desk/wall 
reversal. 
3. Remove the knockouts from the desired mounting holes as 
illustrated in Figure 4-2. 
4. Replace the lower housing. 
Make sure that all wires are clear. 
Wall Mountinq 
-- -a 
Mount the station directly on the wall using two, #lo, panhead screws 
(obtained locally), or mount it on a wall jack cover plate. 
1. 
2. Thread the #lo screws into the wall within l/8-inch of the 
surface. Refer to Figure 4 for the spacing dimensions. 
Insure that the housing is converted properly for a wall mounting 
installation (see above instructions). 
3. 
4. Pull out the latching lever. 
Position the keyhole shaped holes in the bottom of the station 
over the #lO screws or the cover plate studs. Slide the station 
down until a slight click is felt. 
5. Push the latching lever in to lock the station in place. 
6. 
To remove the station, pull out the latching lever, lift to unsnap 
both screws or studs from the bottom housing, and lift the station 
away from the wall.
