Congratulations! You have purchased the 420, a versatile fully featured 4 line telephone. The
420 is designed to work as a
system, the 420 supports advanced telephone features such as intercom, paging and call
transfer. Up to twelve 420s can be connected as a system.
Plan your system before you install the telephones, remembering the following requirements:
■ The 420 telephones communicate over
the wire on line 1. Line 1 must be
common to all 420 telephones for the
system features to operate.
■ The total length of telephone wiring
connected to line 1 should not exceed
600 feet.
The 420 is designed to support telephone company features, including CENTREX. Caller ID and
Call Waiting Caller ID and other telephone company features require subscription to these
services.
NOTES:
■ You must subscribe to the combined service of Call Waiting and Call Waiting Caller ID to use the Call Waiting
Caller ID feature. Check with your local telephone company for service availability.
■ DSL service on line 1 or 2 may interfere with system communications. Use line 3 or 4 for DSL.

SETTING THE DELAY RING
The DELAY RING is useful in installations where all 4 lines are common (square) and a
receptionist is answering all calls. Each extension would activate the DELAY RING for the
desired period of time except for the receptionist.
Incoming calls would ring at the receptionist extension ONLY for the DELAY RING time. If the
receptionist doesn’t answer, after that time other extensions would begin to ring. By varying the
delay ring time, a hierarchy of back-up for the receptionist can be defined.
Most ring cycles are 6 seconds per ring. So to delay for two rings, program 12 seconds. For
three rings, program 18 seconds, and so on. Programming is in two second increments. The
default is DELAY RING OFF.
NOTE TO VOICE MAIL SUBSCRIBERS:
■ If you set the DELAY RING for LONGER than the number of rings that the voice mail waits before answering,
the phone will never ring.

▼ button until the following screen

SETTING THE PRIME LINE
The PRIME LINE is the line that the 420 attempts to use when going off-hook when the phone
is not ringing. Line 1 is the default.
If the phone is ringing and you go off-hook, the 420 will answer the ringing line. If more than
one line is ringing, the 420 will answer the line that was ringing first.

PROGRAMMING LINE GROUPS / PRIVATE LINE
The 420 system can support up to 12 extensions and 15 lines. This is possible by using line 4
for line groups. This allows additional lines to be shared by extensions. The 420 must be
programmed for line groups for the system functions to operate properly. The chart below
describes a typical line group application using eight lines.

these area codes to determine how to dial Caller ID numbers. LOCAL and HOME area codes will
not be dialed when calling a number stored in a Caller ID record.
When numbers are transferred from the Caller ID database to the DIRECTORY (see
TRANSFERING A CALLER ID RECORD TO THE DIRECTORY on page 33) local and home area
codes will NOT be transferred to allow correct dialing.
If you must dial your home area code when dialing locally, program “000” as your home area

USING A HEADSET
If you wish to connect a headset to the 420, we recommend the Plantronics family of products,
for which the 420 has been optimized. These headsets can be purchased from your telephone
company, your local electronics retailer or from Plantronics directly. Specify a RJ-22 headset
connector when ordering.
A dedicated HEADSET button on the 420 allows you to keep the headset plugged in, and to only
use it when desired.

POWER FAILURE OPERATION
Incoming calls can be received (the phone will ring) and outgoing calls can be made on all four
lines using the handset or headset. An optional 9 volt battery must be installed for power failure
operation. The speakerphone will not function during a power failure.

be affected during a power failure. During a power failure, the Directory and Program Modes will
not operate. New Caller ID data transmitted during a power failure will not be displayed or

TROUBLESHOOTINGADDITIONAL FEATURES
During Initial Set-up, the Phone Beeps Continuously
■ Make sure that each 420 in the system is assigned a unique EXTENSION NUMBER between
11 and 22.
Intercom, Page All, Privacy and/or other system features do not work properly.
■ DSL service can interfere with communication between Executive Series telephones. Usage
should be restricted to Line 3 or 4 and a filter (provided by the DSL provider) should be
installed.
■ Make sure the total length of wiring used in your system is less than 600 feet. If the wiring
is longer, you may need to use a special filter device. Contact the company from which you
purchased the phone to obtain this filter.
■ Installation sites at greater distances from the telephone company central office may also
experience network communication problems. These problems include inability to make or
receive intercom calls or inconsistent call transfers and paging. If you are experiencing
these problems, a filter (part number 3001-01) needs to be installed. Contact the company
from which you purchased the phone to obtain this filter.

USER INSTRUCTIONS
1. This equipment complies with Part 68 of the FCC rules. On the bottom of this equipment is a label that
contains, among other information, the FCC registration number and Ringer Equivalence Number (REN)
for this equipment. If requested, provide this information to your telephone company.
2. The REN is useful to determine the quantity of devices you may connect to your telephone line and still
have all of those devices ring when your number is called. In most, but not all areas, the sum of the
RENs of all devices should not exceed five (5.0). To be certain of the number of devices you may
connect to your line, as determined by the REN, you should call your local telephone company to
determine the maximum REN for your calling area.
3. If your telephone causes harm to the telephone network, the telephone company may discontinue your
service temporarily. If possible, they will notify you in advance. But if advance notice is not practical,
you will be notified as soon as possible. You will be advised of your right to file a complaint with the
FCC.
4. Your telephone company may make changes in its facilities, equipment, operations, or procedures that
could affect the proper operation of your equipment. If they do, you will be given advance notice so as
to give you an opportunity to maintain uninterrupted service.
5. If there is a problem with this unit, the telephone company may ask you to disconnect this equipment
from the network until the problem has been corrected or you are sure that the equipment is not
malfunctioning.
6. Repairs can only be made by the manufacturer or an authorized service agency. Unauthorized repairs
void registration and warranty. Contact seller or manufacturer for details of permissible user-performed
routine repairs, and where and how to have other than routine repairs made.
7. This equipment may not be used on coin service provided by the telephone company. Connection to
party lines is subject to state tariffs. (Contact your state public utility commission or corporation
commission for information.)
