Calls can be made or received by lifting the handset.
Ambient Noise Level Measurement (not applicable to IP stations)
The master station has a function to measure ambient noise level at its
installation site, automatically making the internal setting for proper
hands-free conversation. (IP stations do not have this function.)
When acoustic feedback such as squeal or howl* inhibits hands-free
conversation, recalibrate by re-measuring ambient noise as follows.
* Caused by a portion of the sound output from the speaker returning
to a microphone of the same amplifier.
With the handset in place, press the [
] key and then the
[
] key to begin ambient noise level re-measurement.
"Re-measuring" will appear on the LCD (if the AN-8000MS station is
being used).
After about five seconds, a confirmation tone sounds to indicate that
ambient noise re-measurement has been completed.

2.1.3. PTT conversation
This function makes announcements and
conversations possible to areas with a high
ambient noise level. Pressing the Push-to-talk
key during a conversation enables one-way
conversation from the party who pressed the
Push-to-talk key. Conversation flow is reversed
when the key is released. When both parties
have pressed the Push-to-talk key, the party
who pressed the button last is given
precedence to speak.
Tip
The master station automatically measures the ambient noise level when the Exchange is powered up or
the station is connected to the line. During the measurement, the station's status indicator flashes and the
dial operation cannot be performed.
