1. Dial the telephone number of the Model 400.
2. Let the telephone ring once and then hang up.
3. Wait approximately ten seconds
4. Call the Model 400 back.
It will answer the telephone on the first ring.
Explanation: The pattern of one ring, followed by a second call (within 30
seconds), signals the Model 400 to answer your incoming call, bypassing
the telephone answering device.
NOTE: Special Case: If the Model 400 shares the same line with a
telephone answering device, and during certain time periods, frequent,
incoming calls are expected on that line, then you may want to
temporarily disable the TAD feature. If you leave the TAD enabled, it
will not adversely affect normal operation, but if two outside telephone
calls are received within the same 30-second time window, the Model
400 will interpret this pattern as a signal to answer the telephone. If this
occurs, press any key on the Model 400 to hang up.

If a telephone answering device is not used on the same telephone line as
the Model 400, make sure that the TAD feature is disabled, or turned off.
Only Rings Until Answer programming will determine how incoming
calls are answered. For example, if you program Rings Until Answer to 3,
incoming calls will be answered in 3 rings.

The Listen-in Time is the amount of time you can listen to sounds from
the Model 400’s built-in microphone at its installation site. When you call
in for a Status Report, the Model 400 announces Listen-in Time at the end
of its first round of status readings, saying, “Listen for (programmed time
entered).” The programmable range is from 0 to 255 seconds (or up to 4.17
minutes). The default value is 15 seconds.
NOTE: The microphone is also used to monitor high sound level. See
Chapter 5, Section 5.10 through Section 5.11.1.
