TECH NOTE 1
PRIVACY (COL OVERRIDE) ON VA 41210
(PAGE 54 INSTALLATION & PROGRAMMING MANUAL)
The explanation of the privacy feature is a bit confusing when used in conjunction with CO
Line override terminology. Privacy (initial set "0" for all stations) means that
a station programmed in this manner cannot override any other station regardless of
whether that station has been programmed as a "0" or "1".
No privacy (programming set "1") means that a station
programmed in this manner can be overridden by any other station regardless of whether
that station has been programmed as a "0" or "1".
TECH NOTE 6
INTERMITTENT SYSTEM LOCKUP/RESET OF VA61410 KSU's
The intermittent system lockup and/or reset that has been reported on scattered VA61410
systems can be corrected with the replacement of the RAM chip found on CPU to the top with
a revision level number on it. This chip is attached to a socket for easy removal and that
socket is designated 1C2.
The actual change of this chip is done as such:
1. Power the system down.
2. Remove CPU Card #3 from the KSU, and remove the card from the
plastic holder.
3. Install new chip in 1C2 in same direction as old chip was removed
taking care not to bend any leads.
4. Replace card into plastic sleeve , and reinstall in the KSU.
5. Power the system up.
The proper revision level that is needed to solve this version 1.1. This chip is installed
on all KSU's shipped from the factory after September 1987. The serial number on the KSU
will read 87I, 87J... where the number is the year of production, and the letter is the
month of production. This chip can be mailed out upon request from Technical Support if
the one in your cabinet is an earlier version. We can be reached at (201) 392-4843. Once
this change is made, the old software chip should be returned to:

As a reminder - once the VA61410 system has been installed, switch #1 on CPU Card #3
should be set to the "Hold" position, and this switch should remain in that
position until the system is taken out of operation, as per "General Operational
Procedures" found on page 36 of the Installation and Programming Manual. Some
technicians have been leaving this switch in the " CLR" position, which can
result in programmed memory loss and the
possibility of system lockup and/or system reset for no apparent reason.
TECH NOTE 07
PROGRAMMABLE PRIVACY RELEASE TIME ON VA-309 AND VA-824
There is an additional programmable parameter for system-wide alteration of the privacy
release timing feature found on the VA-309 and VA-824 systems. Previously, to release
privacy to a second station, the user originally on the CO call accessed the
"CONF" key, allowing the second party to enter the ongoing CO call. If this
action was not completed in the prescribed time period, the procedure would have to be
repeated.
System program number 118 is a program to vary the time period allotted for the second
person to access the CO. This program can be altered to allow no privacy release, a 10
second time period in which the party can enter the CO call, (default), a 30 second time
period in which the party can enter, or an unlimited time to enter.
HIT THE ON\OFF KEY THEN * 0 0 0 1 #
THEN ENTER * 1 1 8 FOLLOWED BY
DATA ENTRY 0 = NO PRIVACY RELEASE
1 = 10 SECOND RELEASE PERIOD
2 = 30 SECOND RELEASE PERIOD
3 = UNLIMITED RELEASE PERIOD
THEN HIT THE # KEY TO STORE THE DATA THEN THE ON\OFF KEY TO EXIT
TECH NOTE 7 (YES, there are two notes with number 7)
SINGLE TELEPHONE FEATURES THAT ARE AVAILABLE WITH VA41210, VA61410
KSU's
1. Any single line telephone can access an outside line via 01 for CO line, 02 for CO line
2 etc. up to the highest CO line installed in that particular system.
2. Internal calling to any station, and reception of an internal call via dialing the two
digit station number.
3. Placing a call on hold is done by flashing the hookswitch, and retrieving it is done in
the same manner. To use this function may require a change to program 104.
4. Hold recall will work as a normal function of the system on any call put on hold from a
single line instrument.
5. A single line telephone can be a part of a conference call, but may not initiate the
conference.
6. If more than two lines are simultaneously ringing the single line phone will not ring
on any number of lines above two. However, the user on that phone can access ringing line
by dialing the number of that line. For example, if CO lines 1 and 2 are ringing on the
system, and lines 3 and 4 begin to ring, the user on this single line instrument can
access either of those lines by picking up the handset and dialing "03" or
"04" if they know, or are told that line 3 or 4 is ringing.
7. Single line telephones can have a call transferred to them, but cannot transfer a call
unless the micro processor on the SLT card has the MN1554L411 designation on it. This
number is found on the edge of IC1. If the number on that chip is MN1554L41, it can be
sent to me for replacement with the newer microprocessor chip.
If a new microprocessor chip is desired, send the old one to Technical Support.

TECH NOTE 8
CORRECTION TO "OPTIONAL PROGRAM MANUAL FEATURES" FOR
VA-41212 & VA-61410
Program number 103 on the "Optional Program Features" manual, Connection of Door
Phone" shows the default setting of connections as being designated by a 0.
This manual has the number designation for connection and and no connection as 0 and 1
respectively. In fact, the program parameters really are connection is 1 and no connection
is 0. These units both default to a doorphone connection with a program code of 1.
TECH NOTE 9
ACCESS PROGRAMMING ON VA-82410
There is an error in the manual for programming 9 access on the VA-82410. In the
"Installation and Programming Manual for VA-82410", reference is made on page 59
to see page 14 for further information. The manual should read "see page 18".
Similarly, in the combination VA309 / VA 824 manual on page 78, references is made to page
14, this should in fact read, "see pages 21 and 177".
TECH NOTE 10
CALL FORWARDING ON THE VA-30910, VA-82410
A phone that is forwarded to another phone for intercom and CO calls will forward for
intercom calls, and will ring for CO calls. In order to pick up a forwarded call, the user
must 1) pick up the handset, or hit the on/off key, and 2) access the line that the call
has come in on by dialing 8 + the line number. Example: A CO call comes in on line 1 to a
phone forwarded to a second party. The second party's phone rings, and the user picks up
the handset and dials 81 to get the CO call. It is not necessary for the second phone to
have the same line appearances as the phone that has been forwarded in order to pick up
the ringing line.
TECH NOTE 14
PROGRAMMABLE PRIVACY RELEASE TIME ON VA-309 AND VA-824
There is now a programmable parameter for system wide alteration of the privacy release
timing feature found on the VA-309 and VA-824.
Previously, to release privacy to a second station, the user on the station originally on
the CO call accessed the "CONF" key, allowing the second party to enter the
ongoing CO call. If this action was not completed in the prescribed time period, the
procedure would have to be reinitiated.
System program number 118 is a program to vary the time period allotted for the second
person to access the CO. This program can be altered to allow no privacy release, a 10
second time period in which the second party can enter the CO call, (which is the present
and default condition), a 30 second time period in which the second party can enter the CO
call, or an unlimited time period in which the second party can enter the CO call.
The default condition corresponds to a data entry of "1" , when program number
118 appears on the programming stations LCD.
TECH NOTE 15
SINGLE LINE TELEPHONE FEATURES THAT ARE AVAILABLE WITH VA-30910,
VA-82410 KSU's
1. Making an extension call from SLT
a.) Go off hook
b.) Dial two digit number of extension being called
2. Receiving an extension call at a SLT
a.) Pickup handset after phone rings
3. Making a CO call from a SLT
a.) Pickup handset after phone rings
b.) Dial 8 plus the line number desired (or 9 if
the KSU is registered as a hybrid unit)
c.) Dial telephone number
4. Receiving a doorphone call (the ring cadence will be the same as a CO ring cadence)
a.) Pickup handset after phone rings
b.) Dial "75" from SLT to have voice communication with doorphone A or dial
"76" to have voice communication with doorphone B
5. To page from SLT to one or all groups
a.) Go off hook
b.) Dial "#,0,0" , "#,0,1" , "#,0,2" , or "#,0,3"
depending on which group is to be accessed, "#,0,0" will page all groups
simultaneously
6. To open a door from SLT (voice communication cannot be done
simultaneously)
a.) Go off hook
b.) Dial "78" from SLT to open door A or dial "79" to open door B
7. Meet me page (answering a page from a SLT)
a.) Go off hook
b.) Dial "#,#" or "*,*"
8. Dial code access to pickup a ringing intercom call at another station (SLT cannot
pickup ringing CO call to another station)
a.) Go off hook
b.) Dial "*,*"
9. To pickup a call from a SLT that was placed on hold by a proprietary phone, the SLT
user must know the line that the call came in on. The SLT user then dials 8 + the line
number to get the call. A SLT user cannot pickup a CO that was place on hold by another
SLT, unless and until a dial tone is heard in the handset of the SLT that is trying to
access the call on hold. This time period is immediate if a VA-30941 SLT card is being
used, and in 15 seconds if a VA-30942 combination card is being used. (This can be
determined by the hold recall timer) When the SLT that put the call on hold begins to
ring, the second SLT can access the call on hold by dialing 8 plus the line number that
the
10. CO line transfer from a SLT (screened only)
a.) When in conversation, flash hookswitch
b.) Dial two digit extension number of the person to whom the call will be transferred
c.) Talk to person at that extension number
d.) Hang up handset
11. Hold recall tome defaults to 0, resulting in a recall time of 6 seconds when a caller
is put on hold from a SLT. There may be as much as an 8 second delay for this to happen
depending on exactly when the call was placed on hold in relation to the hold recall timer
of the system. Hold recall cannot be removed from a SLT.
12. If intercom call parameters are set to voice call for intercom calls, intercom calls
made to a SLT will always be tone (ringing) calls.
13. Ring cadence for CO calls to a SLT is 2 seconds on, 4 seconds off. Ring cadence for
intercom calls is 1/2 second on, 1/2 second off, 1/2 second on 4 1/2 seconds off.
14. To enter an account code from a SLT the user must flash the hookswitch, then when the
hold recalls the phone, they must flash again, access the "#", then access
"8" plus the one digit line number.

TECH NOTE (Note number unknown)
DSS CONSOLE OPERATION ON THE VA824 AND VA1232
The effect of the DSS console on the operation of the paired proprietary phone causes the
paired phone to default to certain line key assignments that cannot be changed to Flexible
Feature Keys. CO line keys number 1 through 6 cannot be reassigned to Flexible Feature
Keys even though they appear to have taken the new program code to make them
Flexible Feature Keys. The philosophy here is that if the DSS console is being used, there
are probably enough stations in the system to warrant at least 6 CO lines.
Since the VA 824 has the capability to have only 1 DSS console (which must be paired to
station 10), station 10 will be the only affected station as far as line key assignments
go. The VA 1232 has the capability to handle up to 4 DSS consoles connected individually
at any odd numbered extension. Should Flexible Feature Key assignments be attempted to be
made on the VA 1232 to any phone paired to any DSS console, the CO line Keys can indeed be
programmed to be Flexible Feature Keys. The exception, once again, will be the CO line
keys in positions 1 through 6 on the proprietary phone at station 10, if there is a DSS
console paired with it on station 11.
