U-Line 2175RS I recently installed my undercounter refrigerator and It makes a two toned beeping sound ever 30 seconds and there is a message in the digital board ER. Do you know what this is.

It is called a stutter dial tone and usually means that you have messages on you voice mail.... But its is sounding like a motor boat, and sounds like your in a tunnel while talking. You may need to call your local repair. Could be a bad line card.. as long as its happening on all your phones..

A busy tone (Busy Signal) and a reorder tone are two similar on-off repeating tones that differ in the spped that they beep on and off. Some lay terms for a reorder tone is a Fast Busy tone. Both types of tones use two different frequency tones simultaneously, 480 and 620 Hz, for the beep sound. Busy tones are a half second of tone and a half second of silence, repeated. Today's reorder tone is a quarter second of tone and a quarter second of silence repeated, twice as fast as a busy; a long time ago the cadence was a little different.

seems a bit hi depoending on ambiant,
but you should be running like 160-10

While you are away from your home or
office, you can use a touch-tone phone,
or a pulse (rotary) phone with a pocket
tone dialer (available through your local
RadioShack store) to enter your PIN and
do any of the following:
• set the phone to answer or not
answer calls
• listen to your messages
• record a new outgoing message
• erase messages
• monitor the room where the phone
is located
Notes:
• You cannot remotely operate the
phone using its handset or another
telephone on the same line as the
phone.
• You can also listen to the message
recorded on Line 2 by making a call
to Line 1’s number (or vice versa).
USING THE TOLL-SAVER
If RING TIME is set to TS (toll-saver),
(see “Setting the Number of Rings” on
Page 15), the phone answers after three
rings if you have new messages (ones
you have not listened to). If there are no
new messages, the phone answers after
five rings. This gives you time to hang
up before the phone answers so you
can avoid unnecessary long-distance
charges.
Note: Toll-saver works only on the line
you called. If Line 1 has no new messages,
but Line 2 has one, the telephone
answers after five rings when you
call Line 1.
USING REMOTE
COMMANDS
Follow these steps to operate the phone
from a remote location.
Note: If you wait more than 15 seconds
between keypresses, the phone sounds
a long beep and hangs up.
1. Dial your phone number and wait for
the phone to answer.
2. If the phone is not set to answer
calls, it answers after about 10 rings
and sounds a series of beeps.
3. When the outgoing message begins
(or the phone sounds a series of
beeps), press #, then enter your PIN
within 2 seconds.
If the PIN is correct, the phone announces
the day and time, then it announces
the number of new and old messages.
The phone plays all new messages,
then beeps about every two seconds to
let you know it is ready to accept remote
commands.
Notes:
• If the phone does not respond, try
entering your PIN again. If you enter
an incorrect PIN three times, the
phone beeps and hangs up.
Remote Operation 27
• When the phone is operating from a remote location, it stops all answering functions
and rC appears on the display on the base. The phone resumes answering
functions when it is no longer in remote operation, if you have not turned it off.
• The remote playback of incoming messages is limited to 4 minutes. If you have
more messages after 4 minutes have passed, you must press # 2 again to listen
to the rest of the messages.
• When using remote operation, you can only delete the current message during
playback. You cannot delete all the messages stored at one time.
The following table shows the remote commands you can use.
Note: Remote operation stops when someone picks up the handset and presses either
LINE 1 or LINE 2 (whichever is flashing), or any phone on the same phone line.
