Speakerphone Performance Tips
The speaker on your MLS-18D, MLS-12D, or MLS-12 phone has a sensitive
sound-activated switch. Room acoustics and background noise can affect the
proper operation of the speakerphone. To ensure that your speakerphone
works effectively, follow these guidelines:
Avoid placing your phone in areas with high background noise caused by
loud voices, radios, heaters, air conditioning fans, printers, copiers,
typewriters, or other noisy office equipment.
Avoid rustling papers near the microphone (lower right corner of your
phone).
Avoid talking before the other person is finished speaking. When you
both talk at the same time, only one person’s voice comes through.
Do not use your speaker to make announcements over a loudspeaker
paging system connected to your system.
When talking, always face your phone and stay within two feet of it.
If you have difficulty hearing the other party, try increasing the speaker
volume. If you have background noise, try turning off the the microphone
when the party at the other end is speaking and turning it on when you
speak. If the difficulty persists, lift the handset to continue the
conversation.
Standard Telephones
In addition to system phones, you can connect industry-standard touch-tone or
rotary dial telephones—and even some feature phones with built-in calling
features—directly to the system. You can also combine standard phones on the
same extension with system phones or other devices, without using expensive
adapters or connectors.
Standard phones can do many of the things that system phones can do, and
you can save money by using them in certain situations when a system phone is
not needed. Follow these guidelines when using standard phones:

Use standard phones as power failure backups. System phones will not
work without power. In the event of a power failure, standard phones at
extensions 10 and 16 can connect to lines 1 and 3, respectively, for
continued operation. You can connect standard phones in combination
with system phones at power failure extensions, or you can simply keep
spare standard phones at those extensions to serve as replacement in
case of a power failure.
Set Automatic Line Selection for standard phones to “intercom first.”
This enables a user at a standard phone extension to access system
features, including intercom calling.
To use a system calling feature, press [
# ] followed by its dial code.
(Instructions for using these features on standard phones are included in
Chapter 5, “Feature Reference.”)
