TURES section. Program entries as described below. Refer to 
page 4-5 for general programming information, if needed. 
(1) Place the PRG EN switch in the ON position. 
(2) From the desired keyset, program the keyset features as 
follows. 
a. C.O. 
line restriction: Designates the C.O. line(s) 
that cannot be used to make outgoing calls from the 
keyset. Only incoming calls, calls on hold, and 
recalls may be accessed on these C.O. lines. No 
C.O. lines are restricted during initialization. 
1. While on hook, dial #l. 
2. 
Press the line key(s) that will be restricted. 
For example, dialing #l and pressing line keys 2 
and 3 will prevent the keyset user from using 
C.O. lines 2 and 3 for outqoinq calls.

incoming call on 
line key to flash 
on all keysets. If desired, this program can be 
used to designate the C.O. line(s) that will ring 
for incoming calls at the keyset. For example, if 
C.O. 
lines 1 and 3 are designated, calls will 
audibly ring in on those lines, but not on lines 
3-6. When the system is initialized, only the 
attendants keyset (intercom number 10) is assigned 
ring-in for all C.O. lines.

While on hook, dial #2. 
2. 
Press the line key(s) that are to audibly ring 
for incoming calls at this keyset.

to default status, skip this step.) 
3. Lift and replace the handset.

c. Keyset  options: No  options  are  preset  during  ini- 
tialization. 
1.  While  on  hook,  dial  #3. 
2.  Dial  the  desired  option(s).  For  example,  dial- 
ing  #3123  will  enable  options  1,  2,  and  3.  (To 
return  to  default  status,  skip  this  step.) 
Option  1  -  Incoming  page  disable:  Internal 
pages  will  not  be  heard  through  this  keysets 
speaker. 
Option  2  -  Ring  intercom  first:  Incoming  in- 
tercom  calls  will  rinq  until  they  are  answered. 
The  keyset  user  must-press  the-ON/OFF  key  or 
lift  the  handset  to  answer  intercom  calls.

-  Night  answer:  Incoming  calls  pro- 
grammed  to  ring  in  at  the  attendants  keyset 
will  audibly  ring  in  at  this  keyset  when  the  system  is  in  night  ring  mode.  C.O.  lines  that 
are  programmed  to  audibly  ring  only  at  keysets 
other  than  the  attendants 
keyset  are  not 
affected  by  night  ring  mode.  An  incoming  call 
causes  the  associated  line  key  to  flash  on  all 
keysets  in  both  day  and  night  ring  modesh 
Option  4  -  Speakerphone  activation  pre-select 
disable:  Prevents  the  speakerphone  from  being  activated  automatically  when  a  line  key  or  an 
Executive  Keysets  DSS/BLF  key  is  pressed.  When 
this  option  is  enabled,  the  keyset  user  must 
press  the  ON/OFF  key  to 
activate  the 
speakerphone. 
Option  6  -  Toll  restrict:  Restricts  toll-call 
,dialing  at  the  keyset,  depending  on  the  system  options  that  were  enabled. 
3.  Lift  and  replace  the  handset. 
Repeat  the  programming  sequence  for  each  keyset.  Remem- 
ber  to  complete  each  programming  sequence  by  lifting  and  replacing  the  handset. 
When  all  of  the  keysets  have  been  programmed,  return  the  PRG  EN  switch  to  the  OFF  position.

1. INTRODUCTION 
1.01 
This section describes the troubleshooting procedures to 
follow in the event of a system or keyset malfunction. 
2. 
DEFECTIVE UNIT RETURN POLICY 
2.01 
If it is necessary to return defective equipment after per- 
forming the troubleshooting procedures in this section, follow 
the instructions below. To aid record keeping, order a box of 
two-part material return authorization (MRA) tags in advance from 
Inter-Tels Order Processing Department. 
NOTE : When returning the KSU for repairs, place a piece of paper 
between 
(1) 
(2) 
(3) 
(4) 
(5) 
(6) the battery and its clip to prevent it from discharging. 
Obtain an MRA number from Inter-Tels Order Processing 
Department. Write it on an MRA tag. 
Identify the unit by the equipment name, part number, 
and serial number. 
Describe the defect and, if applicable, identify the 
intercom number or C.O. line related to the defect. 
Document the estimated length of time the item had been 
in service prior to the failure. 
Attach the upper portion of the MRA tag to the item. 
Retain the bottom portion for your files. 
Write the MRA number and ATTN: MRA on the outside of the 
shipping box.

3. TROUBLESHOOTING 
A. 
PRE-TROUBLESHOOTING CHECKLIST 
3.01 Use this troubleshooting checklist before you start the 
system troubleshooting procedures. It may save you time and 
possibly eliminate the need for detailed troubleshooting. 
NOTE: 
In locations where there is low humidity, static can build 
up= This often causes small shocks or sparks when metal objects 
are touched. Although the internal metal components of the sys- 
tem are well insulated, 
a large static charge could cause an in- 
terruption in the systems digital signals. If this occurs, the 
system would perform a reset, which may cause dropped calls or 
reset features. If the KSU or keysets are located in high-static 
areas, 
take precautions to eliminate the static. 
If problems 
persist,

Is the problem caused by user errors? Use the feature 
according to the instructions in FEATURES.

Are the integrated 
circuits, PCBs, and equipment cables securely seated and 
connected? Refer to INSTALLATION for more information.

the RUN LED does not light: 
Check the AC fuse that is accessible from the 
right side of the KSU. 
If open, replace it (2A, 
25OV, slow-blow). 
Check the breaker to the isolated, dedicated, AC 
power source. If tripped, reset it. 
Connector 57 on the Main Control PCB is not con- 
nected properly. Refer to page 2-7 for the 
location of the connector. 
the RUN LED is flashing: 
There may be insufficient voltage available from 
the AC power source. Measure the AC voltage. 
If it is low, contact an electrician. 
If the AC power is sufficient, there is a prob- 
lem on the Main Control PCB. 
Replace the KSU. 
If the problem involves a programmable feature, place 
the PRG EN switch in the ON position and check the ERROR 
LED for an indication of a data base error. (The ERROR 
LED will not flash unless the PRG EN switch is ON.)

Follow the 
procedures given below.

ROM failure: A major system error has oc- 
curred. Place the PWR switch in the OFF 
position for 10 seconds, then return it to 
the ON position. If the flashing does not 
stop, replace the KSU. 
6 System/station programming: 
An error has 
been detected in one of data base program- 
ming areas. Either initialize the data base 
or reprogram the areas that are affected. 
(User-programmable f.eatures such as call 
forwarding and night ring mode can be cor- 
rected by the keyset user or attendant.) 
Possible effects of the error include: 
All lines are subject to toll restriction. 
No line is programmed for call forward to 
the public network. 
Keyset options are incorrect.* 
Ring-in assignments are incorrect.* 
Call forward mode is incorrect.* 
C.O. line restriction is incorrect.* 
Timers, night ring mode, 
and the system 
toll restriction option have been returned 
to default status. 
*Can affect more than one keyset. 
7 System/station speed dialing: 
An error has 
been detected in one or more system or sta- 
tion speed-dial numbers. 
The faulty number 
has been erased and can be reprogrammed by 
the attendant or the keyset user. 
b. Initializing the system will cause the ERROR LED to 
stop flashing for errors 6 and 7. 
If you do not 
wish to initialize and prefer to reprogram the af- 
fected area, manually stop the flashing LED by plac- 
ing the PRG EN switch in the OFF position and then 
returning it to the ON position.
