Troubleshooting

The screen displays 

FAIL.

•  The phone has been disconnected from AC 

power. When AC power is restored, the screen 
returns to the usual display, and one-touch 
numbers will be retained but the redial numbers 
will be erased.

Display screen is blank.

•  Make sure the power cord is connected to both 

the phone and an electrical outlet not controlled 
by a wall switch.

The call privacy feature 
does not work.

•  In some installations that have fiber optic service 

(digital service to the building, analog service 
within the building) the signals to the extensions 
may not support the call privacy feature.

Error tone (fast busy sig-
nal) is heard when making 
a page call.

•  The 

Do Not Disturb feature is activated at the 

extension you are calling.

A double beep sounds 
every 30 seconds.

•  There is a call on hold at this extension. Press 

and release the 

LINE button of the call on hold 

to return to the call and turn off the reminder 
beep.

Operation during a power 
failure.

•  This phone operates during a power failure if 

a working battery is installed. You will be able 
to answer calls with the handset, and dial calls 
using the dial pad keys and the one-touch or 
redial features. No other features will work until 
power is restored. All programming and voice 
messages are retained during a power failure.

Cannot join a conversation 
in progress.

•  The call privacy feature prevents another set 

on the system from interrupting a conversation. 
Make sure you press the 

LINE button to release 

privacy. (See the 

Call privacy section on the 

user’s manual.)
