DESCRIPTION AND INSTALLATION

1. GENERAL

1.01 This section covers the installation of the KS-14580

Telephone Answering Device.

1.02 The KS-14580 Telephone Answering Device is a machine

used to furnish automatic telephone answering and re-

cording service on central office and P.B.X. extension lines. The

machine consists of recording and reproducing equipment en-

cas ed in a metal cabinet about 10" x 14" x 8" in size and weigh-

ing about 40 lbs. Th e machine can be used on individual lines and

2 and 4-party lines with full selective ringing. It is necessary

to use a modified 531C subscriber set when the machine is used

on party lines.

1.03 The machine is arranged to respond to an incoming ring

with an announcement message up to 30 seconds in

length. At the end of this messa ge, the caller may record an

incoming message of abo ut 25 seconds maximum length . The

recording and reproducing is done on vinylite record s. The larger

record (KS-14583 List 1) which is 8" in diameter is used for

recording incoming messag es and will accommodate a maximum

of 130 ZS-second mes sages on each side. The smaller record

(KS-14583 List 2) 4" in diameter, is used for the announcement

me ssage and can accommodate one message on each side . The

announcement message is recorded by the subscrib er, using the

associated telephone set transmitt er as a recordin g microphone.

1.04 In response to an incoming ringing signal, the small

turntable which carries the announcement record starts

to turn and the pickup arm is lowered to the announcement

record. The announc ement messa ge is transmitted to the tele-

phone line. At the end of the announcement message, the pickup

arm is restored, tl1e sma ll turntable stops and the large turntable

start s to turn. About 1 second later, a tone signal is transmitted

over the telephone line indicating to the calling party that the

machine is ready to record his message. About 23 seconds later,

the tone is again transmitted indicating that the recording period

is about over. About 2 seconds later, the machine releases the

line and is ready to respond to the next call.

1.05 The machine may also be used for answering incoming

calls only, as described in 6.13.

1.06 The subscriber may play back the messages recorded

in his absence by placing the pickup arm at the proper

location on the large record and operating the PLAYBACK

button. The recorded messages are reproduced in the telephone

receiver.

1.07 When the machine is not in use, the telephone line

should be switched to the regular telephone set by de-

pressing the button marked OFF. When this button is depressed,

the line is connected directly to the telephone set in the normal

manner without any bridged equipment in the machine.

1.08 When any button except the OFF button is depressed,

the ringer in the telephone set is disconnected. However,

an incoming ring causes the ringing relay in the machine to pro-

duce an audible signal as an indication of an incoming call. If

required, connections can be made so that the bell in the tele-

phone set will also ring.

3. POWER SUPPLY

3.01 The KS-14580 telephone answering device is designed

to operate on 115-volt, 60-cycle a-c power supply. In no

case should the machine be directly connected to direct current

since serious damage will result. With the use of a suitable

inverter, however, the machine will operate on direct current.

If d-c is encountered, refer the matter through regular organi-

zation channels to the Engineering Department for advice

before proceeding with the work.

3.02 The machine is protected by means of a 2-ampere fuse

which is located under the case at the left rear of the

chassis next to the warning light. Should the machine fail to

operate, this fuse should be checked. The fuse is an S-310-CCT

Littelfuse, 2a.

4. LOCATING

4.01 Locate the machine in accordance with the considera-

tions outlined below. If the customer's wishes cannot

be followed, explain the reason therefor.

(a) The machine must be located within easy reach of the

subscriber's telephone set.

(b) A desk or table sufficiently strong and stable (approxi-

mate weight of KS-14580 Peatrophone is 40 lbs.) and

where ventilation is not restricted is a satisfactory location.

and need not be fastened.

(d) Avoid locations that subject the apparatus to excessive

moisture or heat.

(e) The bottom cover of the machine is provided with

vents or openings for ventilation. The subscriber should

be advised to avoid piling papers, books or other objects

around the machine since this will reduce ventilation and

cause the machine to overheat.

(f) The machine is equipped with a 10' power cord and plug

for connection to a standard power supply outlet.

Note: In view of the above, it may be necessary to relocate

the subscriber's telephone set , so that the power supply

outlet may be conve_nient, and at the same time, a suit-

able support for the machine obtained.

5. INSTALLATION

5.01 Do not connect the machine to the power supply until

all of the installation work described in the following

paragraphs is completed.

6.04 Record a suitable announcement message, e.g., "This

is Exchange 6-9970. You are being answered by an

automatic machine. This is a test record being used by the

Telephone Company to check the service. When you hear the

first tone signal, please leave a message commenting on the

performance. Do not hang up until after you hear the second

tone signal." While recording, use transmitter in the normal

manner and speak loudly enough to keep the volume indicator

(see Fig. 1) flashing brightly.

6.05 At the end of the message, immediately depress the

OFF button and hang up the telephone. This order

should be followed or the sound of the hangup will be recorded

on the record.

6.06 Always depress the OFF button immediately after the

last word of the announcement message. This results

in a record on which the groove stops at the end of the message

and permits the pickup arm to operate a switch that trips the

machine into its incoming recording cycle. This avoids having

the calling party wait for some time before hearing the first

tone signal.

6.07 When recording an announcement message, the large

turntable will stop automatically after 30 seconds, thus

preventing a longer message from being made. If the message

is incomplete when the turntable stops, it must be rerecorded

on an unused side of a record.

6.08 Remove the small record from the large turntable and

place it on the small turntable. Place the pickup arm at

the forward end of the bridge as far as it will go (see Fig. 1).

Remove the hand set from its mounting, depress the TEST

TALK OUT button, and listen to the announcement message

in the hand set receiver. Check to be sure that the message is

complete and intelligible. When listening to the announcement

message in this manner, the volume is automatically adjusted

to be less than will actuallv be transmitted to the line when the

machine responds to a call.

6.09 If the recorded announcement message is satisfactory,

proceed with a test of the incoming recording.

6.10 Place a large record on the large turntable. Place the

recorder head on the record so that the index mark

on the head coincides with the first mark on the cover shield

plate. If the test record is partially used, place the recorder

head over an unused portion. Depress the AUTOMATIC but-

ton. The READY lamp will light and the WARNING lamp

will go out. The machine is now ready to automatically answer

a call. The large turntable will make approximately one revolu-
