Interpreting LED Prompts
Issue 3 April 2006 21
Since there is no display, the 4601 uses its LEDs to indicate error, wait, data entry, and other
conditions. Use the following table to interpret and understand the phone’s LED signals.
If This LED Is Doing This For This Amount of Time Then
Message Waiting
indicator at the top
of the phone and
the Message
button LED on the
left middle of the
faceplate
Flashing on
and off 500 milliseconds on, 500
milliseconds off,

The phone is waiting for
you to enter data.

faceplate
Illuminated,
but not
flashing,
winking, or
fluttering
Steadily User input is not allowed
(i.e., processing is
occurring) or a voice
message is waiting.
Call Appearance
Line a’s indicator Winking one
or more times 200 milliseconds on, 50
milliseconds off The telephone is providing
feedback after you enter
(press) a numeric digit from
1 to 9. This occurs, for
example, when registering
your phone for the first time
(see Registering the Phone
in Chapter 2: Using Your
4601 IP Telephone).
Basically, the indicator
“winks out” the digit you
pressed (for example, if
you pressed 4, Call
Appearance Line a’s
indicator winks four times).
Each subsequent digit you
press causes Call
Appearance Lines a and b
to alternate winks.
