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.
Cannot Access Program Mode
■ Is the extension off-hook? You cannot program the phone and talk on it at the same time.
Telephone Does Not Ring
■ Make sure the Do Not Disturb (DND) feature is not activated.
■ Make sure ringers are turned on.
■ If there are several non-system phones on the line that do not ring, disconnect some of
them.
■ If the INTERCOM light flashes but you do not hear a paging signal, make sure the Do Not
Disturb (DND) feature is not activated.
■ If you subscribe to Telephone Company Voice Mail, make sure the Delay Ring setting is not
greater than the time it takes for Voice Mail to answer. See pg. 13.
Telephone Handset is Dead
■ Make sure the coiled handset cord is plugged into the HANDSET jack, not the HEADSET jack.
See pg. 7.
Intercom Paging Signal Not Received
■ Make sure you have programmed your extension number correctly. Line 1 must be
connected at all extensions and must be the same telephone number/line for Page and
Intercom to work properly.
■ Make sure the Do Not Disturb feature is turned off at the extension you are calling.
Cannot Join a Conversation in Progress
■ The PRIVACY feature prevents another extension on the system from interrupting a
conversation. Press the LINE button to release privacy.
TROUBLESHOOTING ADDITIONAL FEATURES
A dedicated HEADSET button on the 420 allows you to keep the headset plugged in, and to only
use it when desired.
USING A HEADSET
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.
The Caller ID database and the Directory database are stored in non-volatile memory and will not
be affected during a power failure.
POWER FAILURE OPERATION
When the back-up battery becomes old or weak, the word BATT will appear on the display.
